One of my favorite cake shortcuts is using a soft drink with a box of cake mix. Have you tried this? You only need three ingredients to make this cream soda cake, and I’ll show you how. That means you can serve a tasty dessert for about five dollars.
I love recipes that are simple, delicious, and affordable. This cake ticks all three boxes and is perfect for birthdays, casual get-togethers, or any time you want a quick sweet treat.

This Cream Soda Recipe Is
- Budget-friendly
- Quick and easy
- Made with a boxed cake mix
- A sweet, crowd-pleasing dessert
Ingredients Needed
This is one of the simplest cakes to prepare, and you can customize it in many ways. The ingredients are shelf-stable (except the whipped topping) and inexpensive. Keep them on hand for an easy dessert anytime. If you prefer, freeze the whipped topping until you are ready to use it.

Ingredients:
- White cake mix (15 oz) – Use any white cake mix you prefer; they are often on sale or available at discount stores.
- Cream soda (1 ¾ cups, divided) – Use cream soda in the batter and to flavor the whipped topping for a soft vanilla-soda note.
- Cool Whip (8 oz) – Fold in ¼ cup of cream soda for an easy frosting. If you prefer, use stabilized whipped cream instead.
- Optional garnish – Sprinkles, fresh berries, or crushed root beer candies to decorate.
How to Make this Simple Recipe
The full, printable recipe card appears below, but here is a clear step-by-step summary so you can prepare the cake quickly.
1. Preheat the oven according to the instructions on the cake mix box (typically 350°F). Grease a 9×13 baking dish with non-stick spray.
2. In a large bowl, combine the dry white cake mix with 1 ½ cups of cream soda (about one can). Stir with a wooden spoon for about 2 minutes until a batter forms and is well combined.

3. Pour the batter into the prepared 9×13 pan and smooth the top. Bake for about 30 minutes or according to the box directions. A toothpick inserted into the center should come out clean when the cake is done.

4. Allow the cake to cool to room temperature in the pan; placing the pan on a cooling rack helps air circulate and speeds cooling.

5. For the frosting, stir the remaining ¼ cup of cream soda into the tub of Cool Whip until smooth and evenly flavored. You can omit the extra soda if you prefer a firmer topping.

6. Spread the cream soda-flavored whipped topping evenly over the cooled cake. Garnish with fresh berries, sprinkles, or crushed candies, if desired.

7. Serve immediately or refrigerate until ready to serve. Chilling the cake briefly can help the topping set and improve sliceability.
Recipe Variations
- Try different sodas for varied flavors: orange soda, lemon-lime soda, or root beer all work well.
- Make cupcakes instead by portioning the batter into a muffin tin and baking according to the cake mix instructions for cupcakes.
- Customize the decoration for holidays by using themed sprinkles or colored candies.
- Use a stable vanilla frosting instead of Cool Whip if you want a dessert that keeps longer at room temperature.
- Create a glaze by mixing powdered sugar with a little soda until you reach the desired consistency and drizzle it over slices.

Storing Cake
Refrigerate: Store leftover cake in an airtight container in the refrigerator for up to 4 days for the best texture and flavor.
Freeze: You can freeze the cake (without delicate garnish) in a freezer-safe container for up to 3 months. Thaw in the refrigerator overnight before serving.
