I found this recipe on a bag of Publix All Purpose Flour and have been using it ever since. I made 7 up pound cake regularly as a teenager. This is a variation on that recipe. It produces a moist delicious pound cake that is even better when topped with Fluffy Lemon Frosting.
3 cups sugar
1 ½ cups butter, softened
5 eggs
1 teaspoon lemon extract
3 cups all-purpose flour, sifted
1 cup lemon-lime soda at room temperature
Preheat the oven to 325°. Line 2 loaf pans with parchment.
Beat the butter and sugar in a large bowl with an electric mixer on high speed until creamy.
Add the eggs one at a time beating well after each addition. Add the lemon extract and mix well.
Add the flour and soda alternately beginning and ending with flour. Mix until combined after each addition.
Pour the batter into the prepared pans. Bake for 1 hour or until a toothpick inserted in the center comes out clean. Cool in the pan on a wire rack for 15 minutes then remove from the pan and cool completely.
The loaves freeze well. If frosting, cut one loaf in half and frost with Fluffy Lemon Frosting.
