Melt Milky Ways with 1 stick butter. Remove from heat and let cool completely (lukewarm) – if not, you will not get a light cake.
Cream remaining 2 sticks of butter with sugar.
Add eggs and cooled chocolate candy mixture.
Mix flour and soda together and add alternately with buttermilk, blending well. Add vanilla and nuts.
Bake in greased/floured 13”x9” pan at 325° for 50-55 minutes.
