1 package (18.25 ounces) lemon cake mix
1 egg
1 cup lemon-lime soda
Confectioners' sugar for topping
Recipe
Preheat the oven to 350°F. Coat a 9" x 13" baking dish with nonstick cooking spray.
In a large bowl, combine all the ingredients except the confectioners' sugar; mix well and pour into the baking dish. Bake for 30 to 35 minutes, or until a wooden toothpick inserted in the center comes out clean.
Let cool completely. Sprinkle with confectioners' sugar, slice, and serve.
