Ingredients
Scale
- For the Cake:
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 2 cups granulated sugar
- 1 cup 7Up
- 1 cup vegetable oil
- 1/2 cup sour cream
- 2 large eggs
- Zest of 1 lemon
- Zest of 1 lime
- 2 teaspoons vanilla extract
- For the Frosting:
- 1/2 cup salted butter
- 6 tablespoons 7Up
- 3 3/4 cups powdered sugar, sifted
- Zest of 1 lemon
- Zest of 1 lime
- 1 teaspoon vanilla extract
Instructions
- Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
- In a medium bowl, whisk together flour, baking soda, and salt.
- In a large bowl, whisk sugar, 7Up, vegetable oil, sour cream, eggs, lemon zest, lime zest, and vanilla until smooth.
- Gradually add the dry ingredients to the wet mixture, stirring until just combined.
- Pour batter into the prepared pan and spread evenly.
- Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Let cool completely.
- Make the frosting: In a saucepan, melt butter with 7Up over medium heat. Remove from heat and whisk in powdered sugar, lemon zest, lime zest, and vanilla until smooth.
- Spread frosting evenly over the cooled cake.
- Allow frosting to set before slicing and serving.
Notes
- Make sure the cake is completely cooled before frosting to prevent melting.
- Sift powdered sugar for a smooth, lump-free frosting.
- Store leftovers covered at room temperature for up to 3 days or in the fridge for up to a week.
- For extra citrus flavor, add a little lemon or lime juice to the frosting.
