Ingredients

For the Cake

1 box (15.25 oz / 432 g) yellow cake mix
1 box (3.4 oz / 96 g) instant lemon pudding mix
4 large eggs
½ cup (115 g) unsalted butter, melted
½ cup (120 ml) 7UP soda
¼ cup (60 ml) lemon juice (fresh is best)
Zest of 1 lemon

Optional Glaze

1 cup (120 g) powdered sugar
2–3 tablespoons lemon juice
½ teaspoon vanilla extract

Step-by-Step Instructions

1. Preheat and Prepare Pan

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or a bundt pan and lightly flour it. You can also line with parchment paper for easy removal.

2. Mix Cake Batter

In a large mixing bowl, combine yellow cake mix and lemon pudding mix.

Add eggs, melted butter, 7UP, lemon juice, and lemon zest. Beat on medium speed for 2–3 minutes until smooth.

Tip: Don’t overmix—stop once all ingredients are fully incorporated.

3. Pour and Bake

Pour batter evenly into the prepared pan.

Bake for:

9×13-inch pan: 35–40 minutes
Bundt pan: 50–60 minutes

Check doneness with a toothpick inserted in the center—it should come out clean.

4. Cool

Allow the cake to cool in the pan for 10–15 minutes. Remove and transfer to a wire rack to cool completely before glazing.

5. Optional Lemon Glaze

In a small bowl, whisk powdered sugar with lemon juice and vanilla until smooth. Drizzle over cooled cake for extra tang and shine.

6. Slice and Serve

Cut into squares or slices. Serve on its own, with whipped cream, or with fresh berries for a stunning presentation.

Tips for the Perfect 7UP Lemon Cake

Use fresh lemon juice and zest for maximum flavor.
Do not overbake—7UP keeps the cake moist, but baking too long can dry it out.
Room temperature eggs and butter blend more evenly.
Bundt pan vs. sheet pan: For bundt, grease well to avoid sticking.

Flavor Variations

Lemon Blueberry Cake: Fold in ½ cup fresh or frozen blueberries before baking.
Coconut Lemon Cake: Add ¼ cup shredded coconut to the batter.

Lemon Poppy Seed Cake: Add 1–2 tablespoons poppy seeds for texture and flavor.

Storage

Room temperature: 3–4 days in an airtight container
Refrigerator: Up to 1 week
Freezer: Slice and freeze up to 2 months. Thaw at room temperature or warm slightly before serving.
