In your mixing bowl, beat together the eggs and sugar until light and fluffy (about 2 minutes on medium high speed). Add your mascarpone cheese. Then, slowly incorporate the all-purpose flour, baking powder and almond extract. Fold your blackberries.
Pour your preparation into the Flexipan®, flatten the batter with your spatula. Cover with Octagonal Bonmat so your cake rises flat.
BAKE!
Bake for 35 minutes at 350F/180C. (Every oven heats differently, monitor your cake from 30min). It is ready when the toothpick inserted into the center comes out clean.
Once your Blackberry Mascarpone Sponge Cake is out of the oven, remove the Bonmat™ and let it cool down for about 10min. Then, Unmold, Serve and Enjoy! Bon Appétit!
