hope you make ROSE’S heavenly CAKES: Peanut Butter Ingots (page 317) as soon as you can. if you haven’t made these, you haven’t tried the bright side of cake baking!
ingots (also known as financiers) are a unique cake batter, made mostly of egg whites, flour and nut flour, and hot melted butter. there is no leavening. they are crisp like heaven on the outside, and cake tender buttery on the inside.
here is a closeup of the egg white, flour, nut batter, prior adding the hot melted butter.
