Here’s my moist, airy, and light Japanese strawberry shortcake recipe with homemade whipped cream. This simple and elegant cake is perfect for celebrating all occasions. Detailed step-by-step picture instructions are included.
Strawberry Shortcake is probably one of the most popular and classic cakes in Japan. Whether it’s for birthdays, Christmas (did you know this cake is also sold as “Christmas Cake”?) or any type of celebration, we enjoy Strawberry Shortcake all year round. Cakes have such a special place in Japanese culture that we even bring them when we visit friends and family.
If you need a classy dessert to serve at your dinner party or something special for a bridal shower, a beautiful homemade Japanese Strawberry Cake fits the bill for the most special occasions. With some basics from the pantry, this simple yet elegant cake is one to remember when celebration season hits. Or when the strawberry is in season in your area, you have good enough reason to whip up this sweet treat to celebrate. I promise, your guests will fall hard for it!
What is the Japanese Strawberry Shortcake?
The concept of the Japanese Strawberry Shortcake may have been originated in the US with some adaptation. Instead of sweet biscuits, a Japanese strawberry shortcake is made of 2-3 layers of sponge cake, with fresh strawberry slices, whipped cream filling, and whipped cream frosting.
This cake might seem rather simple, yet when all the components are prepared perfectly, it comes together as an amazing dessert.
The majority of recipes for Japanese strawberry shortcakes are very similar, so what makes them different? It all comes down to the various techniques you use when making it. I want to thank my dear friend Naomi for spending hours in my kitchen testing different variations of strawberry shortcake recipes with me. We spent days testing and making so many cakes, and we decided this is by far the best one.
Because this recipe requires detailed explanations, it was impossible for Mr. JOC to take step-by-step pictures AND film the video at the same time. Therefore, we decided to focus on the step-by-step pictures this time because I can’t explain everything in our short video. We’ll add a video for this recipe in the future.
Components of Japanese Strawberry Shortcake
This recipe is probably the longest recipe ever on my blog, with close to 50 steps. I know it’s a bit of an overkill but I really think these step-by-step pictures are helpful and I can explain the step a little more in detail along the way.
Japanese strawberry shortcake consists of 3 components: sponge cake, whipped cream, and strawberries. It’s simple as that. However, creating the perfect sponge cake and whipped cream involves many techniques.
And to make a really good shortcake, precise measurement (please use a kitchen scale and thermometer!) really helps, especially if you don’t bake often.
Japanese sponge cake is very moist, airy, light, and it’s not overly sweet. Personally, I think this is the most important part of the cake.
The sponge cake is a genoise cake, made by beating air into the eggs to make it rise rather than using a chemical leavening agent like baking soda or baking powder.
The dimensions of the sponge cake we need to consider include sweetness, elasticity, and texture.
The sponge cake cannot be too sweet or else it overpowers the whipped cream and the tartness of the strawberry. The sweetness has to be perfectly balanced with the rest of the cake.
When you bite into the sponge cake, it needs to have some elasticity and firmness of bite. Once again, if it’s too hard or too soft, it ruins the cake.
Lastly and probably the most critical is the texture of the sponge cake. The size of the bubbles within the sponge needs to be consistent. It should not be too rough on the tongue yet it does need some structure so you can feel them. This is probably the part I tested the most to achieve the perfect result.
By the way, if you want to bake a flat cake (my cake is a little curve on the top), I found a great article to solve this problem!
Freshly Whipped Cream
To make fresh whipped cream is not too difficult. Before you begin whipping cream, make sure to chill your bowl and the heavy cream so that the cream will stay cold longer during the whipping process. Basically, cream whips better when it’s cold. The temperature affects how long it requires to whip, how light and fluffy it will get, and how long it is likely to stay that way (more science here).
My friend and I have tested the different amounts of sugar and we concluded that 8% of sugar to heavy whipping cream ratio gives perfect sweetness for the cake.
Fresh strawberries might not be the easiest ingredient to purchase depends on where you live. I know I’m spoiled in California where we literally have strawberries all year round. When you select the strawberries, make sure they are equal in size and not too large so they’ll be more visually appealing.
Last note, since we do not wash the strawberries but clean them with a damp cloth (to prevent them from going bad and adding moisture to the cream.), I do recommend buying organic ones.
Japanese Strawberry Shortcake for the Holidays
After several recipe testings, I am really happy with my results. My friends and family who enjoyed the cake agreed as well. Since then, I’ve served the Japanese strawberry shortcake several times over the holidays and it’s been a huge hit.
The flavor and texture of strawberry shortcake get even better if you let it rest overnight, so it is also a great make-ahead treat.
Japanese Strawberry Shortcake
For the Sponge Cake
- 3 Tbsp unsalted butter
- 2 Tbsp whole milk (I highly recommend using whole milk instead of reduced-fat milk. I’ve tried using both, and I concluded that whole-fat milk makes a difference with the final result.)
- 4 large eggs (50 g each w/o shell)
- ½ cup sugar (½ cup + 2 Tbsp to be precise)
- 1 cup cake flour (No cake flour? See Notes; if you use a measuring cup, fluff your flour with a spoon, sprinkle it into your measuring cup, and use a knife to level it off. Otherwise, you will end up with more than 120 g of flour.)
- 1 Tbsp butter (for greasing; can also use shortening or cooking spray)
For the Syrup
- 2 Tbsp water
- 3 Tbsp sugar
- 1 Tbsp liquor of your choice (optional; I like orange liqueurs like Grand Marnier or Cointreau.)
For the Fresh Whipped Cream
- 2 cups heavy (whipping) cream (36% or more milkfat) (36% fat; must be at least 30-35% fat)
- 3 Tbsp sugar (8% of heavy cream weight: 480 ml x 8% = 38g)
For the Decorations
- 1 lb strawberries (for filling and decoration; if you like to decorate your cake with strawberries, you want to look for similar-sized strawberries to make it look pretty. Buy an extra pack to increase your chances of finding similar-sized strawberries!)
- 10 blueberries
- 2 sprigs mint leaves
- Gather all the ingredients.
Before We Start
- Make sure the eggs and butter are at room temperature. Sift the cake flour at least twice.
- Place the cake pan on top of parchment paper, trace around the pan, and cut out the circle. Grease one side of the parchment paper and both the bottom and sides of the cake pan with butter. Then fit the parchment paper in the cake pan, greased side up. I avoid parchment paper on the sides because sometimes it pulls the batter and affects the final result of the cake.
- Preheat your oven to 350ºF (180ºC). For a convection oven, reduce cooking temperature by 25ºF (15ºC). It’s always better to preheat longer, preferably 15-20 minutes extra. Tip: You preheat the oven so that all the surfaces inside your oven (walls, floor, door, and racks) are the desired cooking temperature. This makes for an even temperature throughout the oven and you won’t lose as much heat when you open the door for a few seconds. Depending on your oven, preheating might take 10 to 20 minutes.
- Prepare a double boiler. If you have never done this before, please see the Notes section below. Turn on the stove’s heat to high and bring the water in the saucepan (Pot A) to a rapid boil. Once boiling, reduce the heat to maintain a steady simmer. Put the 40 g (3 Tbsp) of butter in the small bowl (Bowl #1) and set over the saucepan. Let the butter melt gently.
- Once the butter is melted, remove the bowl from the saucepan. Then add 30 ml (2 Tbsp) whole milk and whisk to combine. Set aside to keep it around 104ºF (40ºC).
To Make the Sponge Cake
- In a stand mixer bowl (Bowl #2), add 4 eggs and break the egg yolks and whites with your whisk.
- Add 120 g (½ cup + 2 Tbsp) sugar and whisk to combine.
- In a large pot (Pot B), bring about 2 inches of water to 140ºF or 60ºC and maintain the temperature. Then, set the stand mixer bowl (Bowl #2) directly over the pot and whisk constantly so the eggs don’t become scrambled eggs. This method is called a bain-marie (or water bath), where the bowl of food is set directly over a larger container of hot or simmering water. You can also use the double boiler method, where you set the egg mixture bowl (Bowl #2) over Pot B. The bowl doesn’t touch the simmering water of the pot. In both cases, the water tempers the heat to permit gentle, even cooking.
- Whisk until the temperature of the egg mixture reaches 104ºF (40ºC). Remove Bowl #2 from Pot B and set it up on the stand mixer with the whisk attachment.
- Whisk on high speed (level 10) until the mixture is fluffy, for about 2 minutes. The batter should be loose yet thick and glossy.
- When the batter is pale, fluffy, and tripled in volume, reduce the speed to low speed (level 4) for several seconds. Stop the mixer and lift some of the batter with the whisk to check the consistency. If the batter falls off your whisk in a solid line or ribbon on top of the mixture, you’ve reached the “ribbon stage” (see the Notes). Remove the bowl from the stand mixer.
- Add half of the flour to the bowl. Using the whisk, fold gently but thoroughly. Do this by rotating your bowl slowly while simultaneously moving your whisk in a down-and-over motion.
- Add the rest of the flour and fold gently to make sure all the flour is incorporated quickly so your mixture doesn’t deflate.
- With your spatula, take out one scoop of the batter from the bowl and add it to the butter and milk mixture. Tip: If we add the butter and milk mixture into the entire cake batter, the fat in the butter will deflate the batter.
- Incorporate the butter and milk mixture into a small amount of the batter first before adding it to the entire cake batter.
- Add the mixture back into the cake batter by pouring it over a silicone spatula. This prevents the mixture from deflating the batter and helps disperse the mixture. Gently fold until incorporated. When you lift the spatula, the batter should fall like a ribbon.
- Pour the batter into the center of the cake pan, from right above the cake pan. You want to avoid introducing extra air into the batter at this point. Collect the leftover batter in the bowl and pour it around the edges of the cake pan, not the center.
- Firmly tap the cake pan on the counter to release air bubbles in the batter.
- In the preheated oven, bake at 350ºF (180ºC) for 20-25 minutes. Check if the sponge cake is done by inserting a skewer in the middle; if it comes out clean, the cake is ready. While the cake is baking, start preparations for the cake assembly (see below).
- As soon as you take out the cake pan from the oven, drop it on the counter to “shock” the cake so it stops shrinking. Separate the cake from the pan by running a sharp knife or offset spatula around the sides.
- Take the cake out of the pan by placing the wire rack on top and flipping it over.
- Immediately remove the parchment paper.
- Place another wire rack on top and flip it back over. The top of the cake is now facing up.
- Cover the cake with a damp towel until cooled (to keep moisture in the cake). Make sure the towel is thin (not heavy) and wring the water out well so that the towel is damp, not wet. I use IKEA’s thin dish towel. If you keep the sponge cake for later use, wrap it with plastic wrap and keep it in the fridge (see Notes).
To Prepare the Cake Assembly (While the Cake is Baking)
- Divide the strawberries into 2 groups, for decoration and for filling. Keep the beautiful, same-sized strawberries for the decoration. Remove the husk and clean the strawberries with a damp paper towel (do not wash, as we don’t want the strawberries to be moist and become moldy). Slice off the core for all the strawberries.
- For the strawberries that we will use for the decoration, cut them in half lengthwise. For the strawberries that we will use for filling, slice them lengthwise into ¼-inch (5 mm) slices.
- To make the syrup, combine water, sugar, and liquor (optional) in a small bowl (Bowl #3). Microwave for 1 minute to dissolve the sugar.
To Make Fresh Whipped Cream (While the Cake is Cooling)
- Prepare an ice bath by placing ice cubes and water in a large bowl (Bowl #4). Place a clean and dry mixing bowl (Bowl #2) in the ice bath and add heavy whipping cream and sugar to keep it cold.
- Transfer the mixing bowl to the stand mixer and whisk on high speed. The cream will become thicker and smooth. When you lift the whisk out of the cream while it’s still liquid, and the cream holds its shape as it drops, it’s ready. Remove the bowl from the stand mixer and put it back in the ice bath.
To Assemble the Cake
- With a serrated knife, slice the middle of the cooled cake horizontally into half. Now you have 2 layers (top and bottom).
- Place the bottom of the cake on the cake circle. Brush the syrup on the top and sides of the bottom layer. This will help the sponge cake stay moist.
- Using a hand whisk, whisk only the cream at one spot by the edge of the bowl instead of whisking the entire bowl of cream. We will be making whipped cream as we need it. With this approach, we can also control the stiffness of the whipped cream.
- When the cream reaches medium peaks, transfer it to the top of the bottom cake layer. Medium peaks mean when you lift the whisk, the cream will hold its shape, but the tip of the peaks will fold back on itself.
- Spread the whipped cream evenly. If you don’t have enough whipped cream, whip more and add it onto the cake.
- Place the sliced strawberries on top of the whipped cream as you see in the pictures. Keep the center area open by not covering it with strawberries. This will make it easier to cut the cake into slices.
- Whip the cream again at the edge of the bowl.
- Transfer the whipped cream to the top of the strawberry layer. Spread just enough cream to cover the strawberries; do not add too much.
- Place the top layer of the sponge cake over the bottom layer. Brush the syrup on the top and sides of the sponge cake.
- Whip more cream and place it on top of the cake.
- Place the tip of the offset spatula in the center of the cake at a 30-degree angle and turn the cake turntable toward you to create a smooth top. Lightly coat the sides of the cake with a thin layer of whipped cream.
- Now add more cream to the sides, little by little. Place the offset spatula at a 90-degree angle and push the turntable away from you.
- Remove the excess cream from the cake and put it back into the bowl.
To Decorate the Cake
- For a basic decoration, I use a Wilton 2A decorating tip. Put the tip in the piping bag and cut off the tip so the metal will show from the bag. Fold the top half of the bag outward as you see in the picture (over your hands).
- Whip the cream to stiff peaks. When you lift the whisk, the peaks will hold firm. Put the cream into the piping bag. Once you fill the bag halfway, lift up the top half of the bag and push the cream down toward the tip.
- Squeeze the piping bag to test to make sure the cream comes out smoothly. When you’re ready, hold the piping bag at a 90-degree angle and squeeze about a 1-inch-wide ring of whipped cream around the top edge of the cake. This will be the base for the strawberries.
- Decorate and place the strawberries cut-side down on top of the whipped cream. Then squeeze small dollops of whipped cream between and around all the strawberries. Place the blueberries between the whipped cream dollops. Place the small mint leaves as desired to add color.
- For 1 cup cake flour, measure 1 cup all-purpose flour, then take away 2 Tbsp all-purpose flour and add 2 Tbsp cornstarch. Be sure to sift the flour to distribute the cornstarch well before using it in your cake batter.
