Tandy Cake is a yellow cake topped with a peanut butter layer and a hard chocolate glaze. This recipe takes a couple of hours to prepare, but it is well worth the time! It tastes fantastic!
Preheat the oven to 350°F (175 degrees C). Grease and flour a 10x15-inch baking dish. Sift the flour and baking powder together and set aside.
Combine the eggs, sugar, and vanilla extract in a large mixing bowl. Beat with an electric mixer on high speed until light and lemon-colored. Incorporate the flour mixture. 2 minutes in the microwave, or until the milk and margarine begin to bubble. Incorporate into the batter.
Pour batter into a 10x15-inch baking pan. Cook for 20 to 25 minutes, or until a toothpick inserted into the center of the cake comes out clean.
When the cake has cooled, spread the peanut butter evenly around the edges. Refrigerate for 1 hour to set.
Melt chocolate in a microwave-safe dish and spread evenly over peanut butter layer. Allow chocolate to harden in the refrigerator.
