1 box of lemon cake mix
1 box lemon instant pudding mix
3/4 C. oil
1 tsp. lemon flavor
10 oz. 7-Up
Combine all ingredients, except the 7-Up, and mix well. Add the 7-Up and mix again. It will foam up as you add the 7-Up. Bake in a greased and floured 9x13 pan at 300 degrees for 50 minutes. I like to frost it with a cream cheese frosting.
