Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
• In a medium bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
• In a large bowl, cream together butter and sugar until light and fluffy. Beat in eggs one at a time, then stir in vanilla.
• Gradually add the dry ingredients to the wet ingredients, alternating with the 7-Up, beginning and ending with the dry ingredients. Mix until just combined.
• Pour batter into the prepared pan and bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean.
• Let cool completely before frosting or serving.
