A two-ingredient soda cake is a wonderfully simple baking shortcut that yields a light, moist dessert with minimal effort. All you need is one box of cake mix and one can of soda — no eggs, oil, butter, or water required. The carbonation in the soda reacts with the cake mix’s leavening to create a foamy, airy batter that bakes into a fluffy cake. Use any flavor combination of boxed mix and soda to customize the result; some favorite pairings are listed below.
A Fun Shortcut for Beginner Bakers
This method works because boxed cake mixes already include dry ingredients and leavening agents. When you add soda instead of the typical liquids and fats, the carbonation and sweetness replace eggs and oil, contributing moisture, flavor, and lift. Once mixed, the batter becomes foamy and bubbly—signs that the cake will rise and bake up tender and airy. It’s a convenient recipe for rainy afternoons, last-minute gatherings, or any time you want a quick homemade dessert without a long ingredient list.
Helpful Tips & Variations
- Diet soda works: If you prefer less sugar or fewer calories, diet sodas can be substituted with good results.
- Use nonstick spray or parchment: Coat the pan well or line it with parchment so the delicate cake releases cleanly.
- Don’t overbake: Without added fat, this cake can dry out if left in the oven too long. Begin checking at 20 minutes.
- Ensure it’s fully baked: Soda cakes can be gummy if underbaked. The top should be set and slightly golden, the cake should pull away from the pan edges, and a toothpick should come out clean.
- Optional extracts: A splash of vanilla, almond, or rum extract can heighten the flavor depending on the mix and soda you choose.
- Toppings: While the cake itself is technically two ingredients, a simple topping such as powdered sugar, whipped cream, Cool Whip, or a scoop of ice cream adds a finished touch and balances the crumbly texture.
Soda Cake
Equipment
- 9×13 baking pan
- Large mixing bowl
Ingredients
- 15.25 oz box cake mix (any flavor)
- 12 oz can soda (any flavor)
- Optional: Cool Whip, whipped cream, fruit, or ice cream for serving
Instructions
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan with nonstick spray or line it with parchment.
- Empty the cake mix into a large bowl. Pour the can of soda over the mix and whisk until smooth and lump-free. The batter will become foamy—this is normal.
- Pour the batter into the prepared pan and spread to an even layer. Tap the pan lightly on the counter to settle the batter and release large air pockets.
- Bake for about 25–30 minutes, checking at 20 minutes. The cake is done when the top springs back and a toothpick inserted in the center comes out clean.
- Allow the cake to cool completely in the pan before slicing. The cake is delicate, so cooling helps it set and makes it easier to cut.

How to Make Soda Cake Step by Step
Gather the cake mix and a can of soda in your preferred flavors. The example here uses strawberry cake mix with cream soda, but any pairing works. Preheat the oven to 350°F and prepare a 9×13-inch pan with nonstick spray so the finished cake lifts out easily.
Mix the batter: Add the entire box of cake mix to a large bowl, then pour in the 12 oz can of soda. Whisk until the mixture is smooth and mostly lump-free. The batter will foam and look light and bubbly—stop once it is evenly combined to avoid overmixing.
Bake: Transfer the batter to the prepared pan and spread it evenly. Tap the pan on the counter to settle the batter and remove big bubbles. Bake about 25–30 minutes or until the cake springs back and a toothpick inserted into the center comes out clean. Edges should be slightly golden.
Cool and serve: Let the cake cool completely in the pan before slicing. Because the crumb is more delicate than a traditional cake, cooling makes slicing easier. Serve plain or add a topping like Cool Whip, whipped cream, fresh fruit, powdered sugar, or ice cream.
Soda Cake Flavor Combinations
Match cake mixes and sodas to create playful or classic flavor profiles. A few tested combinations are listed above, and you can experiment freely: fruit sodas with fruit mixes, cream sodas with vanilla or strawberry mixes, and root beer with chocolate for a nostalgic treat.
Serving Suggestions
This 9×13-inch cake yields about 12 slices. Cool fully before slicing. Simple toppings work best: a dollop of whipped cream, a scoop of ice cream, a dusting of powdered sugar, or fresh fruit that complements the cake’s flavor. Sauces like fruit compote or a simple chocolate drizzle can also enhance the experience.
Storing Leftovers
- Room temperature: Store covered for 1–2 days without perishable toppings.
- Refrigerator: Keep covered for 3–4 days; add whipped toppings just before serving.
- Freezer: Freeze plain slices wrapped tightly for up to 2 months. Thaw in the refrigerator; texture may be slightly softer.
