Place butter in a small sauce pan and heat on low until melted. Set aside.
In a mixing bowl, whisk the sugar and eggs together. Combine the almond flour, all purpose flour and baking powder. Add the cooled melted butter and almond extract. Mix until it is all incorporated.
Scoop your batter into your Flexipan®. Arrange the peaches on top center facing up. Sprinkle sugar and slivered almonds on top.
BAKE!
Bake for 25 minutes at 350F/180C. (Every oven heats differently, monitor your cakes from 22min). It is ready when the toothpick inserted comes out clean.
Once your Yellow Peaches and Almond Cakes are out of the oven, let them cool down for about 10min. Then, Unmold and enjoy. Bon Appétit!
