3 1/4 cups rolled oats
33 tablespoons butter
1 1/2 cups white sugar

Sift together the oats, butter, sugar, egg and chocolate. Press the mixture into the prepared pans.
Bake at 375 degrees F (190 degrees C) for 10 to 12 minutes, or until a toothpick inserted into the center of the cake comes out clean. Cool in pan on a wire rack.
