ROSE’S heavenly CAKES: Genoise Tres Cafe (page 182) uses coffee on the batter:
the recipe calls to mix coffee extract with the eggs prior beating. i mixed the coffee extract with the warm butter instead. yum!
here is the baked genoise. i adore the cafe colour!
in my opinion, genoise, and all other sponge cakes not using baking powder, bake well on any size and shape pan. for my take, i am using a 7-inch silicone chrysanthemum pan.
