7 Up Bundt Cake

7 Up bundt cake is a Southern classic that proves a humble can of lemon-lime soda can do real baking work. The carbonation in the 7 Up lifts the batter with millions of tiny bubbles, contributing to the cake’s signature tender, almost cloud-like crumb. The citrus oils in the soda also add subtle lemon-lime brightness that pairs perfectly with the lemon extract.

This is a pound cake at heart, with a 1.5:3:3:5 ratio of butter to sugar to flour to eggs that delivers the dense, buttery richness people expect. The 7 Up replaces the milk or buttermilk that would normally provide liquid, and the result is dramatically lighter than a traditional pound cake without losing the signature buttery flavor.

Cream the butter and sugar until truly light and fluffy. This step takes a full 4 to 5 minutes with an electric mixer; rushing it results in a denser cake with less rise. The creaming process incorporates air into the fat, and that air is what helps the cake climb in the bundt pan.

Add eggs one at a time, beating well after each. Adding all five at once shocks the batter and can break the emulsion, leaving you with curdled, broken batter that bakes into a coarse-textured cake.

Pour the 7 Up in last and fold gently. Excess stirring deflates the bubbles before they have a chance to lift the batter in the oven.

Pro Tips

• Grease the bundt pan thoroughly with shortening (not spray) and dust generously with flour. Bundt cakes stick easily to detailed pan designs.
• Tap the filled pan firmly on the counter before baking to release air pockets that can become weak spots in the finished cake.
• Don’t open the oven during the first hour. The temperature shock can collapse the cake.
• Cool exactly 10 minutes before unmolding. Less and the cake tears; more and it sticks to the pan as it cools.
• Dust with confectioners sugar once cool, or drizzle with a simple lemon glaze for extra flavor.

Variations

• Use Sprite or any lemon-lime soda; the recipe works the same.
• Substitute almond extract for lemon for a different flavor profile, almost like a wedding cake.
• Add 1 tablespoon of grated lemon zest to the batter for additional fresh lemon punch.
