What You’ll Need
For the Cake:
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow cake mix | 1 box (15.25 oz) | Duncan Hines or Betty Crocker work great |
| Instant lemon pudding mix | 1 box (3.4 oz) | Adds extra moisture and flavor |
| Large eggs | 4 | Room temperature preferred |
| Vegetable oil | ¾ cup | Canola oil works too |
| 7 Up soda | 1 cup | Must be room temperature, not cold |
For the Glaze:
| Ingredient | Amount | Notes |
|---|---|---|
| Powdered sugar | 1½ cups | Sifted for smooth glaze |
| Fresh lemon juice | 3-4 tablespoons | Freshly squeezed is best |
| Butter | 2 tablespoons | Melted and slightly cooled |
| Lemon zest | 1 teaspoon | Optional but adds amazing flavor |
Smart Substitutions:
- No 7 Up? Use Sprite, Sierra Mist, or any clear lemon-lime soda
- Sugar-free option: Diet 7 Up works perfectly
- Gluten-free: Use gluten-free yellow cake mix
- Dairy-free glaze: Replace butter with vegan butter
Step-by-Step Directions
- Prepare your workspace. Preheat oven to 350°F (175°C). Generously grease a 12-cup bundt pan with butter or cooking spray, making sure to get into all the crevices. Dust lightly with flour and tap out excess—this prevents sticking.
- Let the 7 Up come to room temperature. Open the can and let it sit for about 30 minutes. Cold soda can affect the cake’s texture, so this step is crucial for the best results.
- Mix the dry ingredients. In a large bowl, combine the cake mix and pudding mix. Whisk together until evenly distributed—no lumps should remain.
- Combine wet ingredients. In a separate bowl, lightly beat the eggs. Add the oil and room-temperature 7 Up, mixing gently to preserve some carbonation.
Pro Tip: Don’t worry if the 7 Up fizzes a bit when mixed—that carbonation is what makes this cake incredibly light and fluffy!
- Bring it all together. Pour the wet ingredients into the dry mixture. Mix on medium speed for 2 minutes until smooth and well combined. The batter will be slightly thinner than regular cake batter—this is perfect!
- Pour and bake. Transfer batter to the prepared bundt pan, spreading evenly. Tap the pan gently on the counter to release air bubbles. Bake for 55-60 minutes, or until a long toothpick inserted in the center comes out clean or with just a few moist crumbs.
Don’t Peek! Resist opening the oven door for the first 45 minutes—this can cause the cake to sink in the middle.
- Cool properly. Let the cake cool in the pan for exactly 10 minutes—no longer! Run a knife around the edges, then invert onto a wire rack. Cool completely before glazing, about 1-2 hours.
- Make the glaze. Whisk together powdered sugar, lemon juice, melted butter, and lemon zest until smooth. Adjust consistency with more lemon juice (thinner) or powdered sugar (thicker).
- Glaze and serve. Drizzle glaze over the completely cooled cake, letting it drip down the sides naturally. Let glaze set for 15 minutes before slicing.

Expert Tips for Success
For Perfect Texture:
- Room temperature ingredients mix more easily and create better texture
- Don’t overmix once flour is added—this can make the cake tough
- Proper pan preparation is crucial for bundt cakes—be generous with grease and flour
Timing Matters:
- Cool for exactly 10 minutes before turning out—too short and it breaks, too long and it sticks
- Glaze only when completely cool or it will absorb into the cake instead of creating a beautiful coating
Storage Solutions:
- Store covered at room temperature for up to 4 days
- Refrigerate if your kitchen is very warm—bring to room temperature before serving
- Freeze unglazed cake wrapped tightly for up to 3 months
Flavor Variations:
- Orange twist: Use orange cake mix and orange soda (like Crush)
- Lime version: Add lime zest to the batter and lime juice to the glaze
- Vanilla enhancement: Add 1 teaspoon vanilla extract to the batter
Make-Ahead Secret: This cake actually improves overnight! The flavors meld beautifully, making day-two slices even more delicious.
Common Questions
Why does this cake use soda instead of liquid?
The carbonation in 7 Up creates tiny air bubbles throughout the cake, resulting in an incredibly light and moist texture that’s impossible to achieve with regular liquids. The citrus flavor is just a bonus!
Can I use a different type of soda?
Absolutely! Sprite, Sierra Mist, or any clear lemon-lime soda works perfectly. You can even experiment with other clear sodas like ginger ale for a subtle spice note.
What if I don’t have a bundt pan?
You can use two 9-inch round pans (reduce baking time to 25-30 minutes) or a 9×13 inch rectangular pan (35-40 minutes). Just adjust the baking time accordingly and test with a toothpick.
Can I make this cake from scratch instead of using a mix?
While you certainly can, the beauty of this recipe lies in its simplicity. Cake mixes are specifically formulated to work with additional ingredients like pudding mix and soda, ensuring consistent results every time.
How do I know when the cake is done?
Insert a long toothpick or cake tester into the thickest part of the cake. It should come out clean or with just a few moist crumbs. The cake will also start to pull slightly away from the pan edges when done.
Why did my glaze disappear into the cake?
This happens when the cake isn’t completely cool. The warm cake absorbs the glaze instead of letting it set on top. Always wait until the cake reaches room temperature before glazing.
