I got this recipe from my mother--she used to make it for club meetings and church functions when I was younger. Now my kids like it too! One thing to note--there is no baking soda or baking powder in this recipe--the beaten eggs make it rise.
Cream butter and sugar; add eggs and beat until fluffy. Add all other ingredients except cherry pie filling and beat well. Spread batter into a 10 X 15 jelly roll pan that has been greased and floured or sprayed with cooking spray. Spread cherry pie filling on top of batter in spoonfuls making 4 rows the length of the pan. Bake in a 350 degree oven for 35-45 minutes. May sprinkle with powdered sugar or drizzle with powdered sugar icing when done baking.
