There’s something timeless about a Lemon 7-Up Cake. It’s the kind of cake that shows up at Sunday dinners, church potlucks, and family gatherings — always stealing the spotlight with its tender crumb, refreshing citrus flavor, and buttery richness. This cake gets its legendary moisture and lift from a surprising ingredient: 7-Up soda. The carbonation creates an airy texture, while the lemon-lime flavor enhances the fresh citrus notes, making every bite bright, soft, and unforgettable.
This is the perfect cake for anyone who loves old-fashioned baking with a modern twist. The combination of real butter, fresh lemon juice, and soda produces a cake that’s moist enough to melt in your mouth, yet sturdy enough to slice beautifully. Finished with a tangy lemon glaze, this cake feels both comforting and elegant — ideal for holidays, tea time, or any occasion that calls for something sweet and special.
Ingredients
For the Cake:
-
1½ cups unsalted butter, softened
-
3 cups granulated sugar
-
5 large eggs, room temperature
-
3 cups all-purpose flour
-
½ teaspoon baking powder
-
½ teaspoon salt
-
1 tablespoon lemon zest
-
2 tablespoons fresh lemon juice
-
1 teaspoon vanilla extract
-
1 cup 7-Up soda (room temperature)
For the Lemon Glaze:
-
1 cup powdered sugar
-
2 tablespoons fresh lemon juice
-
1 tablespoon milk
-
½ teaspoon lemon zest
Instructions
1. Prepare the Bundt Pan
Preheat your oven to 325°F (165°C). Generously grease a 10-inch bundt pan with butter or baking spray, making sure to coat every curve. Dust lightly with flour and tap out the excess. This step ensures the cake releases perfectly after baking.
2. Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter until light and fluffy. Gradually add the sugar, beating for 5–7 minutes. The mixture should become pale and airy. Proper creaming creates the cake’s soft texture and rich flavor.
3. Add the Eggs
Add the eggs one at a time, mixing well after each addition. This keeps the batter smooth and prevents curdling. The eggs give structure and contribute to the cake’s delicate crumb.
4. Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt. Slowly add this dry mixture to the butter mixture, alternating with the 7-Up soda. Start and end with the flour. Mix gently to keep the batter light and avoid overworking it.
5. Add Flavorings
Stir in the lemon zest, lemon juice, and vanilla extract. The fresh lemon gives the cake its vibrant citrus aroma and flavor.
6. Pour and Bake
Pour the batter evenly into the prepared bundt pan. Smooth the top with a spatula. Bake for 75–85 minutes, or until a toothpick inserted into the center comes out clean. The cake should have a golden crust and a soft, moist interior.
7. Cool the Cake
Let the cake cool in the pan for 15 minutes, then carefully invert it onto a wire rack. Allow it to cool completely before glazing.
Make the Lemon Glaze
In a small bowl, whisk together powdered sugar, lemon juice, milk, and lemon zest until smooth. Drizzle the glaze over the cooled cake, letting it run down the sides for a beautiful finish. The glaze adds a tangy brightness that balances the cake’s sweetness.
