Place butter in a small sauce pan and heat on low until melted. Set aside.
In a mixing bowl, whisk together the all-purpose flour, baking powder, matcha powder and sugar. Make a well and add the eggs. Gently start mixing inwards going outwards with your mini whisk. Add the heavy whipping cream, a splash at a time while continuing mixing. Finally, add the vanilla bean paste and cooled melted butter. Mix until it is all incorporated.
Pour your batter into your Flexipan® and arrange the raspberries on top by gently pushing them down.
BAKE!
Bake for 30 minutes at 350F/180C. (Every oven heats differently, monitor your cake from 25min). It is ready when the toothpick inserted comes out clean.
Once your Raspberry Matcha Sponge Cake is out of the oven, let it completely cool down before unmolding. Then, Serve and Enjoy! Bon Appétit!
