Air Fryer 7-Up Cake (Easy 5-Ingredient Bundt!)

Nothing takes me back to my childhood quite like a slice of Air Fryer 7-Up Cake. My mom clipped the original recipe from a magazine ad decades ago, and that lemon-lime soda is still the secret to one of the most tender, moist cakes you’ll ever pull out of your air fryer. The best part? You only need five simple ingredients and a box of yellow cake mix to make it happen — no fancy techniques, no stand mixer, and no heating up the whole kitchen.

If you’ve never baked a Bundt cake in the air fryer, this is the recipe that will convince you. The circulating hot air sets the edges beautifully while the center bakes evenly around the hole in the pan — which means you sidestep the dreaded raw middle that trips so many people up. Once you taste it, you may never go back to the oven. (If you’re brand new to air fryer baking, start with my full guide on how to make a cake in the air fryer.)

Why You’ll Love This Air Fryer 7-Up Cake

• Only 5 ingredients. A box of cake mix does the heavy lifting, and the 7-Up does the magic.
• Incredibly moist and light. The carbonation in the soda lightens the crumb, while instant lemon pudding keeps every bite tender and flavorful.
• No oven needed. Perfect for hot days, small kitchens, or anyone who loves cooking with an air fryer.
• Foolproof Bundt shape. Baking in a Bundt pan solves the under-baked-center problem for good.
• Endlessly dress-uppable. Dust it with powdered sugar, drizzle with glaze, or serve it à la mode.

Ingredients You’ll Need

Here’s everything that goes into this 7-Up Bundt cake, plus a few notes so it turns out perfectly the first time:

• Yellow cake mix: Any standard 15.25 oz box works. Yellow gives you that classic buttery base, but a white or lemon mix works beautifully too.
• Instant lemon pudding mix: This is the flavor backbone. It deepens the citrus notes and adds richness and moisture. Vanilla pudding works if you want a milder, more neutral cake.
• 7-Up soda: Use it fresh and fizzy; the bubbles help lift the batter. Sprite or any clear lemon-lime soda is a fine swap.
• Large eggs: Bring them to room temperature for the smoothest batter.
• Vegetable oil: Keeps the crumb soft and moist. Canola or melted coconut oil both work.

How to Make Air Fryer 7-Up Cake

This comes together in one bowl in about ten minutes of hands-on time.

Step 1: Mix the batter. In a large mixing bowl, combine the yellow cake mix, instant lemon pudding, 7-Up, eggs, and vegetable oil. Beat until smooth, scraping down the sides of the bowl so everything is fully incorporated.

Step 2: Prep the pan. Generously coat a Bundt pan with nonstick cooking spray, making sure to get into every groove so the cake releases cleanly.

Step 3: Fill and air fry. Pour the batter into the prepared pan. Set it into the air fryer and bake at 320°F for 20–25 minutes.

Step 4: Check for doneness. The cake is ready when a toothpick inserted into the center comes out clean. If the top is browning too quickly, loosely tent it with foil. Let the cake cool in the pan for 10–15 minutes, then invert onto a wire rack to cool completely before glazing or slicing.

Tips for the Best 7-Up Cake

• Grease the pan thoroughly. Bundt pans have a lot of nooks — a baking spray with flour is your best friend here.
• Don’t overmix. Beat just until smooth. Overmixing develops gluten and can make the cake dense.
• Know your air fryer. Every model runs a little differently, so start checking at the 20-minute mark. Use the toothpick test as your real guide, not the clock.
• Let it cool before flipping. Releasing too early is the number-one cause of a cake that sticks or splits.

Variations and Substitutions

One of the reasons I love this recipe is how easy it is to make your own:

• Make it lemon-forward. Add a teaspoon of lemon zest to the batter and finish with a simple lemon glaze. If you love bright citrus desserts, you’ll also want my Air Fryer Lemon Bundt Cake.
• Go chocolate. Swap in a chocolate cake mix and chocolate pudding for a totally different cake — or just make my Air Fryer Chocolate Cake instead.
• Add a swirl. Love a ribbon of cinnamon running through your Bundt? Try the same air-fryer method with my Air Fryer Cinnamon-Swirl Bundt Coffee Cake.

How to Serve Air Fryer 7-Up Cake

This cake is wonderful on its own, but it’s also a perfect canvas:

• Dust generously with powdered sugar for a classic finish.
• Drizzle with a simple lemon glaze, caramel, or melted chocolate.
• Slice and serve with a scoop of vanilla ice cream.
• Top with fresh berries for a light, summery dessert.

How to Store and Freeze

Room temperature: The cake is fine left out for a few hours while serving, but for anything longer I recommend refrigerating it to extend its freshness.

Refrigerator: Store leftover cake in an airtight container in the fridge for up to 5 days. Bring slices to room temperature before serving for the best texture.

Freezer: Wrap the cooled, unglazed cake (whole or sliced) tightly in plastic wrap and foil and freeze for up to 3 months. Thaw overnight in the fridge or on the counter, then glaze and serve.

Can I Make This 7-Up Cake in the Oven Instead?

Absolutely. If you’d rather use the oven, preheat it to 350°F, pour the batter into your greased Bundt pan, and bake for about 30–35 minutes, or until a toothpick inserted in the center comes out clean. The air fryer is faster and keeps your kitchen cool, but the oven gives you the same tender results.

Frequently Asked Questions

Why do you use 7-Up in cake? The carbonation acts as a gentle leavening agent, creating a lighter, more tender crumb, while the lemon-lime flavor adds a subtle brightness that balances the sweetness.

Can I use a different soda? Yes. Sprite, Sierra Mist, or any clear lemon-lime soda will give you nearly identical results. Avoid dark sodas unless you’re going for a different flavor entirely.

Do I have to use a Bundt pan? A Bundt pan is ideal because the center hole helps the cake bake through evenly in the air fryer. If your air fryer fits a small round or loaf pan, you can use that — just adjust the time and watch the center closely.

My air fryer doesn’t fit a full-size Bundt pan. What do I do? Measure your basket first. Many 6-quart air fryers fit a 6- or 7-inch Bundt or fluted pan. You can also divide the batter between smaller pans and bake in batches.

How do I know when the cake is done? Insert a toothpick into the thickest part of the cake. If it comes out clean or with a few dry crumbs, it’s done. Wet batter means it needs a few more minutes.
