Ingredients
- 1 box Pillsbury Zero Sugar Cake Mix
(Choose any flavor—vanilla, chocolate, yellow, or even spice cake work beautifully.) - 1 (12 oz) can diet soda
(Use clear sodas like Diet Sprite, Diet 7-Up, or Diet Ginger Ale for light-colored cakes. Use Diet Coke or Diet Dr. Pepper for chocolate mixes.)
Optional Add-Ins (Not Required But Recommended)
- ½ teaspoon vanilla extract (for extra flavor)
- Ground cinnamon (for spice or yellow cake mixes)
- Mini chocolate chips or sugar-free sprinkles (small handfuls only)
- A few finely chopped apple slices or banana slices (for fruitiness and volume)
Equipment You’ll Need
- Mixing bowl
- Hand whisk or electric mixer
- Muffin tin (standard 12-count)
- Cupcake liners or nonstick spray
Instructions
- Preheat the Oven
Set your oven to 350°F (175°C) and line your muffin tin with paper liners or grease with nonstick spray. - Combine Ingredients
In a large bowl, empty the entire box of zero sugar cake mix. Slowly pour in the can of diet soda. Stir gently at first to prevent fizzing over. Once it settles, whisk or beat until the batter is smooth and lump-free—about 1–2 minutes. No eggs or oil needed! - Optional: Add Extras
If you’re incorporating vanilla extract, fruit slices, or spices, gently fold them in now. - Fill the Muffin Tin
Divide the batter evenly into the 12 lined muffin cups. Each should be about ¾ full. - Bake the Cupcakes
Place in the preheated oven and bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean. Baking times may vary slightly depending on your oven and choice of cake mix. - Cool Completely
Remove the cupcakes from the oven and let them cool in the tin for 5 minutes. Transfer to a wire rack to cool completely before serving or storing.
Serving Suggestions
- Enjoy plain, or top with a dollop of light whipped topping or sugar-free frosting.
- Pair with fresh fruit like banana slices, strawberries, or a few apple wedges.
- Serve alongside coffee, tea, or a glass of almond milk for a cozy, satisfying snack.
Storage Tips
- Room Temperature: Store in an airtight container for up to 3 days.
- Refrigerator: Will last up to 5 days chilled. Let come to room temperature before serving for best texture.
- Freezer: Wrap each cupcake individually and freeze for up to 2 months. Thaw in the fridge overnight or at room temp for 1–2 hours.

Frequently Asked Questions
Q: Can I make these as a full cake instead of cupcakes?
Yes! Pour the batter into a 9×13-inch baking pan sprayed with nonstick spray and bake at 350°F for 25–30 minutes, or until a toothpick comes out clean.
Q: Can I use regular soda?
You can, but it will add sugar and calories. Diet soda helps keep the recipe light and low in sugar.
Q: Can I use any zero sugar cake mix?
Pillsbury’s Zero Sugar line works best for consistent texture and flavor. Other brands may vary in ingredients and baking times.
