For cake:

Cream together butter and shortening. Add sugar and eggs. Sift dry ingredients together and add vanilla. Add alternately with cream mixture. Bake in a large pound cake pan (tube pan) 9 to 10 inches. Put wax paper in bottom. Spray sides and bottoms. Cook 325 degrees for 80 minutes. My stove cooks it in 1 hour at 300 degrees. Don’t overcook it. It will be dry. Some stoves cook different.

For icing:

Melt butter and chocolate together. Add sugar and vanilla. Cream well and spread. It should be firm. And spread good not runny. I let it set a few minutes and run a knife around tube and it comes out good.
