Recipe for Heath Bar Dessert. Mix everything except whipped topping and Heath bits in a medium sized bowl. Mixing it with a wire whip works great. . .
Preheat oven to 350 degrees F. In a large bowl, using a pastry blender, mix the flour, granulated sugar, brown sugar and butter together until fine particles form. Remove 1/2 cup of the mixture to use to top cake. Blend in the buttermilk, egg, vanilla, baking soda and baking powder and transfer the batter to a greased and floured 9x13 inch pan.
