Ingredients
For the Cake:
-
3 cups all-purpose flour
-
3 cups granulated sugar
-
5 large eggs, room temperature
-
1 cup unsalted butter, softened
-
½ cup vegetable shortening
-
¾ cup 7UP (room temperature)
-
2 tablespoons lemon zest
-
2 tablespoons fresh lemon juice
-
1 teaspoon vanilla extract
For the Lemon Glaze:
-
2 cups powdered sugar
-
¼ cup 7UP
-
1 tablespoon fresh lemon juice
Step 1: Prepare the Pan and Oven
Preheat your oven to 325°F (165°C). Grease and flour a 10-inch Bundt or tube pan thoroughly, making sure to coat every groove. This cake is rich and delicate, so proper greasing ensures it releases cleanly after baking.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and shortening together until smooth and creamy. Gradually add the granulated sugar and continue mixing for 4–5 minutes until the mixture becomes light, fluffy, and pale in color. This step is essential for creating the soft texture that makes this cake so special.
Step 3: Add Eggs and Flavorings
Add the eggs one at a time, beating well after each addition. This helps create a stable and smooth batter. Next, mix in the lemon zest, lemon juice, and vanilla extract. The fresh citrus aroma will instantly brighten the batter.
Step 4: Add Flour and 7UP
Reduce the mixer speed to low. Slowly add the flour, alternating with the 7UP, beginning and ending with the flour. Mix just until combined—do not overmix. The carbonation in the 7UP helps create a light, airy texture without the need for baking soda or baking powder.
Step 5: Bake the Cake
Pour the batter evenly into the prepared pan and smooth the top. Bake for 65–75 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden and slightly cracked.
Once baked, remove the cake from the oven and allow it to cool in the pan for about 10–15 minutes.
Step 6: Prepare the Lemon Glaze
While the cake cools, whisk together the powdered sugar, 7UP, and lemon juice in a small bowl until smooth. The glaze should be pourable but thick enough to cling to the cake.
Step 7: Glaze and Serve
Carefully invert the cake onto a serving plate or cake stand. While the cake is still warm, slowly pour the glaze over the top, allowing it to drizzle down the sides and soak into the cake. This step adds extra moisture and a bright lemon finish.
Let the cake cool completely before slicing for clean, beautiful slices.
