How to Make Easy Lemon 7UP Cake
Step 1: Preheat and Prepare the Pan
Preheat your oven to 325°F (165°C). Generously grease and flour a Bundt pan, making sure to coat all the grooves to prevent sticking. Set aside.
Step 2: Cream Butter and Sugar
In a large bowl, cream the softened butter and granulated sugar together using a mixer on medium speed. Beat for 4–5 minutes, until the mixture is light, pale, and fluffy. This step is essential for a tender pound cake.
Step 3: Add Eggs
Add the eggs one at a time, beating well after each addition. Scrape down the sides of the bowl as needed to ensure everything is evenly mixed.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt.
Step 5: Mix the Batter
Gradually add the dry ingredients to the butter mixture, mixing on low speed. Slowly pour in the 7UP soda, followed by the lemon juice, lemon zest, and vanilla extract. Mix just until combined. Avoid overmixing to keep the cake tender.
Step 6: Bake
Pour the batter evenly into the prepared Bundt pan and smooth the top. Bake for 70–80 minutes, or until a toothpick inserted into the center comes out clean.
If the top begins to brown too quickly, loosely tent the cake with aluminum foil during the last 15 minutes of baking.
Step 7: Cool and Glaze
Allow the cake to cool in the pan for 10–15 minutes, then carefully invert it onto a cooling rack.
While the cake is still warm, whisk together the powdered sugar and lemon juice to make the glaze. Drizzle the glaze slowly over the cake, allowing it to soak in.
