7UP Lemon Cake Recipe

This classic 7UP Lemon Cake is a rich, buttery Bundt cake with a delicate lemon flavor and an incredibly tender, moist crumb. The addition of 7UP gives the cake a light citrus character while helping create a soft texture. It is simple enough for an everyday dessert but beautiful enough to serve at family gatherings, holidays, birthdays, potlucks, and afternoon tea.

Introduction

7UP cake became popular as a classic American-style soda cake, particularly because home bakers discovered that lemon-lime soda could add both flavor and moisture to traditional cake recipes. The combination of butter, sugar, eggs, flour, and 7UP produces a dense yet tender pound-cake-style dessert.

For the best result, use room-temperature eggs and softened butter. Properly creaming the butter and sugar is especially important because it helps create the cake’s fine texture.

Ingredients

For the Cake

3 cups all-purpose flour
3 cups granulated sugar
1½ cups unsalted butter, softened
5 large eggs, room temperature
7.5 ounces 7UP, approximately 1 cup
2 tablespoons fresh lemon juice
1 tablespoon finely grated lemon zest
1 teaspoon vanilla extract
½ teaspoon salt

For the Lemon Glaze

1½ cups powdered sugar
2 to 3 tablespoons fresh lemon juice
1 tablespoon 7UP
1 teaspoon finely grated lemon zest
½ teaspoon vanilla extract, optional

Equipment

10-inch Bundt pan
Large mixing bowl
Electric mixer
Measuring cups and spoons
Rubber spatula
Wire cooling rack
Small bowl for the glaze

Instructions

Method 1: Prepare the Pan

Begin by generously greasing a 10-inch Bundt pan with softened butter or baking spray. Make sure you reach all the grooves and sides of the pan.

Lightly dust the pan with flour, then tap out any excess.

Preparing the pan carefully is important because this cake is rich and moist and can otherwise stick to the detailed surface of a Bundt pan.

Method 2: Prepare the Ingredients

Remove the butter and eggs from the refrigerator ahead of time so they can reach room temperature.

Measure the flour carefully. If possible, spoon the flour into your measuring cup and level it with a knife rather than scooping directly from the flour container.

Wash and dry the lemon. Finely grate the yellow outer skin to obtain the lemon zest, avoiding the bitter white pith underneath.

Juice the lemon and set the juice aside.

Method 3: Cream the Butter and Sugar

Place the softened butter in a large mixing bowl.

Beat the butter on medium speed until smooth and creamy.

Gradually add the granulated sugar and continue beating for approximately 4 to 6 minutes.

The mixture should become noticeably lighter and fluffy.

This step is one of the most important parts of the recipe. Properly creamed butter and sugar help give the finished cake a beautiful, fine crumb.

Method 4: Add the Eggs

Add the eggs one at a time.

Beat well after each addition, scraping down the sides of the bowl as necessary.

Do not add all five eggs at once. Adding them gradually helps the mixture remain smooth and evenly incorporated.

Add the vanilla extract, lemon zest, and lemon juice.

Mix briefly until everything is combined.

Method 5: Add the Flour

In a separate bowl, whisk together:

All-purpose flour
Salt

Add approximately one-third of the flour mixture to the butter mixture.

Mix on low speed just until incorporated.

Add about half of the 7UP and mix gently.

Continue alternating between the flour mixture and 7UP, beginning and ending with the flour.

Do not overmix the batter.

Once the final flour has been incorporated, stop mixing as soon as you no longer see dry streaks.

Method 6: Add the 7UP

Pour the remaining 7UP into the batter as directed by the alternating method above.

The batter should be thick, smooth, and creamy.

You may notice a slight citrus aroma from the lemon and 7UP.

Avoid vigorously stirring the batter after the soda has been added.

Method 7: Form the Cake

Transfer the batter into the prepared Bundt pan.

Use a spatula to spread the batter evenly.

Gently tap the pan on the counter once or twice to help remove large air pockets.

Smooth the surface.

Method 8: Bake

Preheat your oven to 325°F (165°C).

Place the Bundt pan on the center rack.

Bake for approximately 70 to 85 minutes.

Begin checking around 70 minutes because ovens and Bundt pans can vary.

The cake is ready when:

The top is golden brown.
The cake has pulled slightly away from the sides of the pan.
A wooden skewer inserted into the thickest part comes out clean or with a few moist crumbs.
The center feels firm but springs back lightly when touched.

If the top begins browning too quickly, loosely cover it with aluminum foil during the final portion of baking.

Method 9: Cool the Cake

Remove the cake from the oven and place it on a cooling rack.

Allow it to cool in the pan for approximately 15 to 20 minutes.

Carefully run a thin knife around any areas that appear stuck.

Place the cooling rack over the Bundt pan and carefully invert the cake.

Allow the cake to cool completely before glazing.

Do not try to remove the cake immediately after baking because the structure is still delicate and may break.

Lemon Glaze Method

Place the powdered sugar in a small bowl.

Add 2 tablespoons of fresh lemon juice and 1 tablespoon of 7UP.

Whisk until smooth.

Add additional lemon juice a few drops at a time if the glaze is too thick.

If the glaze is too thin, add a little more powdered sugar.

Stir in the lemon zest.

The finished glaze should be thick enough to coat the cake while still flowing slowly down the sides.

Formation of the Cake

The character of this cake comes from the way the ingredients work together.

The butter provides richness and tenderness. The sugar contributes sweetness and helps create a delicate crumb. The eggs provide structure and richness, while the flour gives the cake its framework.

The 7UP adds liquid and lemon-lime flavor. The carbonation itself is not the primary leavening agent; rather, the cake’s structure comes mainly from the eggs and the mixing method.

The lemon zest and fresh lemon juice intensify the citrus flavor and keep the cake from tasting overly sweet.

The result is a substantial, buttery cake that is moist without being wet and tender without falling apart.

History of 7UP Cake

7UP cakes belong to a long American tradition of incorporating familiar packaged foods and beverages into home baking. Lemon-lime soda became particularly popular in cakes because its citrus flavor naturally complements butter, sugar, and vanilla.

Recipes for soda cakes became especially recognizable during the mid-20th century, when home cooks increasingly experimented with convenient commercial ingredients.

The 7UP cake eventually became known as a Southern-style favorite, particularly when baked in a Bundt pan and finished with a simple lemon glaze.

Its enduring popularity comes from its simplicity: a handful of familiar ingredients can produce an impressive cake with a distinctive citrus flavor.

Serving Suggestions

Once the glaze has set, slice the cake into generous pieces.

It can be served:

Plain with coffee or tea
With fresh strawberries
With fresh blueberries
With whipped cream
With vanilla ice cream
With a spoonful of lemon curd
With fresh raspberries
Alongside afternoon tea
As a dessert after a family dinner

For an especially beautiful presentation, sprinkle a little extra lemon zest over the glaze before serving.

Tips for the Best 7UP Lemon Cake

Use softened butter

The butter should be soft enough to beat easily but should not be melted.

Use room-temperature eggs

Room-temperature eggs incorporate more easily into the butter mixture and help create a smoother batter.

Cream thoroughly

Do not rush the butter-and-sugar stage. Four to six minutes of proper creaming can make a noticeable difference in texture.

Don’t overmix

Once the flour is incorporated, mix only until combined. Excessive mixing can produce a tougher cake.

Use fresh lemon

Fresh lemon zest and juice provide a much brighter flavor than bottled lemon juice.

Grease the Bundt pan carefully

Pay particular attention to the grooves and center tube.

Let the cake cool

Allowing the cake to cool before removing it helps prevent cracking or breaking.

Glaze only after cooling

A completely cooled cake gives you the best-looking glaze because it will remain on the surface rather than immediately melting into the cake.

Variations

Extra-Lemon 7UP Cake

For a stronger lemon flavor, add another teaspoon of finely grated lemon zest to the batter and make the glaze slightly more lemon-forward.

Lemon-Lime Cake

Add a small amount of finely grated lime zest along with the lemon zest for a brighter lemon-lime flavor.

Simple Powdered Sugar Finish

Instead of the lemon glaze, allow the cake to cool completely and dust it lightly with powdered sugar.

Berry-Topped 7UP Cake

Serve individual slices with strawberries, raspberries, or blueberries and a spoonful of lightly sweetened whipped cream.

Lovers of This Cake

This recipe is especially suited to anyone who enjoys traditional pound cakes, buttery Bundt cakes, lemon desserts, and old-fashioned homemade baking.

It is also an excellent choice when you want a dessert that can be prepared ahead of time. The flavor often becomes even more developed after the cake has rested for several hours.

For gatherings, the entire cake can be prepared the day before, covered once completely cooled, and glazed shortly before serving.

Storage

Store the completely cooled and glazed cake in an airtight container at room temperature for up to 3 days.

For longer storage, refrigerate it in a tightly covered container for approximately 5 to 7 days. Allow refrigerated slices to sit at room temperature for a short time before serving for the best texture.

The cake can also be frozen without the glaze. Wrap it tightly in plastic wrap and then in aluminum foil. Freeze for up to 2 to 3 months.

Thaw completely before adding the glaze.
