Peanut Butter - Fudge Marble Cake

Directions

Preheat the oven to 350℉ (180℃).

Grease and flour two 8- or 9-inch round baking pans.

Prepare the cake batters according to the package directions using the eggs, ⅓ cup of oil and water.

In the top of a double boiler, over hot NOT boiling water, melt the peanut butter chips with the remaining 2 Tb of oil, stirring constantly.

Gradually add the peanut butter to the vanilla batter, blending well. Pour the peanut butter batter into the prepared pans. Randomly place spoonfuls of the chocolate batter on top and swirl in as directed on the cake package.

Bake for 30 to 40 minutes or until a wooden pick inserted in the center comes out clean. Cool 15 minutes, in the pans, on a wire rack then remove from the pans and cool completely. Frost as desired.
