Lemon–Lime Pound Cake
This Lemon–Lime Pound Cake is a bright, citrusy twist on a beloved Southern classic—the famous 7UP Pound Cake of the 1950s. Softened butter, sugar, and eggs create a rich, velvety crumb, while lemon zest and extracts infuse every slice with layers of sunny flavor. The secret ingredient, a cup of lemon–lime soda, adds lift and lightness without the need for traditional leaveners. Finished with a glossy Lemon–Lime Glaze and optionally adorned with jewel-like Candied Lemons, this showstopping Bundt is tender, fragrant, and irresistibly nostalgic. A true RizzieFarms keeper.
Ingredients
Pound Cake
- 1 1/2 cups butter, softened
- 3 cups sugar
- 5 large eggs
- 2 tablespoons lemon zest
- 1 teaspoon vanilla extract
- 1 teaspoon lemon extract
- 3 cups all-purpose flour
- 1 cup lemon-lime soft drink (such as 7UP)
- Shortening (for greasing pan)
Lemon–Lime Glaze
- 1 cup powdered sugar
- 2–3 tablespoons lemon-lime soft drink (or mix lemon and lime juice)
- 1/2 teaspoon lemon zest (optional)
Optional Candied Lemons
- 1 lemon, sliced thin
- 1 cup sugar
- 1 cup water
Instructions
-
Preheat the oven
Preheat oven to 350°F. Grease a **10-inch Bundt pan** generously with shortening and dust with flour to ensure easy release.
-
Cream butter and sugar
In a stand mixer on medium speed, beat **1 1/2 cups softened butter** until creamy. Gradually add **3 cups sugar** and continue beating for 3–5 minutes until the butter–sugar mixture is light and fluffy.
-
Add eggs
Add **5 large eggs** one at a time, beating just until each egg is incorporated into the butter–sugar mixture before adding the next.
-
Add citrus flavor
Stir in **2 tablespoons lemon zest**, **1 teaspoon vanilla extract**, and **1 teaspoon lemon extract** until evenly distributed.
-
Alternate flour and soda
Add **3 cups all-purpose flour** to the batter alternately with **1 cup lemon–lime soft drink**, beginning and ending with the flour. Mix on low speed just until each addition is blended—avoid overmixing.
-
Bake
Pour the batter into the prepared **10-inch Bundt pan**. Bake at 350°F for **65–75 minutes**, or until a long wooden pick inserted into the center comes out clean. Shield with foil after 45–50 minutes to prevent over-browning.
-
Cool
Cool the cake in the pan on a wire rack for 10 minutes. Then remove the cake from the pan and allow it to cool to warm or room temperature on the rack.
-
Prepare Lemon–Lime Glaze
In a bowl, whisk **1 cup powdered sugar**, **2–3 tablespoons lemon–lime soda**, and **1/2 teaspoon lemon zest** (optional) until smooth. Adjust consistency with additional soda or sugar.
-
Glaze the cake
Spoon the Lemon–Lime Glaze over the warm or room-temperature cake so it drips down the sides.
-
Prepare Candied Lemons (optional)
In a small saucepan, combine **1 cup sugar** and **1 cup water**. Bring to a simmer, then add thin **lemon slices**. Simmer for 15–20 minutes until translucent. Transfer to parchment to cool before garnishing.
-
Garnish and serve
Top the glazed cake with candied lemons and lime rind twists, if desired. Slice and serve.
Notes
- For maximum flavor, use freshly grated lemon zest rather than bottled.
- A high-quality lemon–lime soda (not diet) provides the best rise and texture.
- This cake keeps well and tastes even better the next day.
