Seven-Up Pound Cake Recipe

+ Directions : This is an old recipe that comes from a request in the local paper for "Classic Recipes". They called the 7-Up bottling company and they did not even know about it. Someone developed this on their own and never let the company know about it. BTW 7-Up comes from the popular card game in the 1930's. Cream the margarine, shortening and sugar together beating until light and fluffy. Add the eggs, one at a time, blending well after each addition. Beat in the flour, then beat in the extract and 7-Up. Blend well. Pour the batter into a well-greased and floured tube pan and bake at 325 degrees F for 1 to 1 1/2 hours.
