1 (10-oz) Hershey Chocolate Bar
1 cup butter
2 cups sugar
1 cup buttermilk
1/2 tsp baking soda
2 1/2 cups cake flour
1 (5.5-oz) can Hershey chocolate syrup
1 tsp vanilla extract
Melt the chocolate bar in the top of a double boiler over hot water.
In a large mixing bowl, cream the butter and sugar together; add eggs, one at a time, beating well after each.
Stir the baking soda into the buttermilk.
Alternately add the buttermilk and the flour into the creamed mixture. Add the melted chocolate, chocolate syrup, and vanilla extract.
Pour batter into a greased and floured 10-inch tube pan (not a Bundt pan) and bake at 350 degrees for 70 minutes or until a wooden toothpick inserted in center comes out clean.
Cool cake and remove from pan. Dust with powdered sugar.
