Cream sugar and butter until smooth. Add one egg at a time and beat. Add flour and stir. Combine Sprite and lemon extract and mix with batter until smooth. Spoon batter into muffin pan with cupcakes liners.
Bake at 350 for 25-30 minutes or until tops turn golden brown.
Note: If you fill the liners more than halfway, your cupcakes may overflow.
These cupcakes are so tasty, they don't need frosting. But if you love the sugary touch, maybe esomething with cream cheese.
