    These Green Tea Chocolates, or as we call them Matcha Nama Chocolates (抹茶生チョコレート) in Japan, simply melt in your mouth.

    As I was testing this recipe, I knew I won’t be able to stop eating them so Mr. JOC took them to work.  He told me later, “The green tea chocolate disappeared in seconds.”  I promise you, it’s really good!

    Irresistible Green Tea Chocolate (Matcha Nama Chocolate) (抹茶生チョコレートの作り方)

    Green tea powder, or matcha (抹茶), has a unique bitter taste to it.  The flavor of “matcha” is quite different from the green tea served at Japanese restaurants.  Matcha is typically used for making tea at traditional Japanese tea ceremony.  This tea tends to be thick and exceptionally bitter, but it goes quite well with wagashi (和菓子), traditional Japanese confectioneries that are very sweet by itself.

    The color of matcha is a bright, beautiful green color, so if your matcha powder doesn’t have that nice vivid hue to it, your matcha is well past its prime.  The green tea powder is also quite pricey, especially if it is of tea ceremony quality, but the culinary grade is good enough for baking and making these chocolates.

    As you may already know, green tea delivers a healthy dose of antioxidants and cancer-fighting power.  Catechins in green tea are also known to have many beneficial health properties and matcha has greater potential health benefits than other green tea.

    In Japan, there are many varieties of green tea chocolate in stores, including green tea Pocky’s, Melty Kiss, Kit Kat and the popular ROYCE’ Chocolate.

    When I made ROYCE’ copycat Nama Chocolate two years ago, I received many requests for the green tea version.  I love anything with green tea, so I’m really happy to finally share this green tea version with you this year. Right in time for Valentine’s Day!

    The cooking process for this recipe is very similar to regular Nama Chocolate recipe, but white chocolate is used instead of regular chocolate.  My only advice for you is to work fast to melt the white chocolate while the cream is warm.

    Rich, yet not so sweet, decadent truffle-like matcha green tea chocolate, it is simply irresistible. If you love green tea sweets, this will be an ultimate treat for you.

    Recipe Notes


    * Make sure the bowls and utensils you are using are perfectly dry. Even a small amount of water/steam can "seize" the chocolate melting process.

    * When buying white chocolate, make sure that it contains cocoa butter because some inferior brands contain vegetable fat. White chocolate should be ivory-colored (white chocolate made with vegetable fat is white-colored).

    * The fat content for heavy (whipping) cream is 38%, which is used to whip cream.


    The two most common problems of working with chocolate are separating and seizing.

    1) Separation (oil came out of the chocolate) happens when you get the chocolate too hot. When chocolate gets too hot, the cocoa butter separates from the solids, and there is no way to salvage it (although you can bake with it and it tastes fine). The best way to prevent separation is to use gentle heat (simmer on lowest heat) and stir frequently. Since we're not using a double boiler in this recipe, make sure you do not bring the heavy whipping cream to a full boil. Remove from heat as soon as you saw bubbles around the edges of the saucepan.

    2) Seizing happens when moisture is introduced to melted chocolate (even a tiny amount of liquid or steam). It happens all the sudden from a smooth bowl of liquid chocolate to a lumpy, grainy mass of chocolate.
