These colorful Fruity Pebbles Cupcakes are a fun, crowd-pleasing treat for birthdays and celebrations. The cupcakes start with a white cake mix but gain extra flavor and texture from Fruity Pebbles cereal added to the batter. The buttercream frosting is enhanced with finely crushed Fruity Pebbles for a vibrant, flavorful finish kids and adults love.
The cereal adds bursts of fruity flavor and beautiful color throughout the cupcakes and frosting. This recipe is simple to make and is adaptable — I often use Fruity Pebbles in other desserts too, like rice crispy treats and cheesecake.

The complete ingredient amounts are listed in the recipe card below.
Recipe variations
- Cake mix alternatives: Try yellow, vanilla, strawberry, or funfetti mixes for different flavors.
- Sheet cake: Bake this as a 9×13 sheet cake instead of cupcakes; spread the frosting and garnish with cereal.
- Mini cupcakes: Use a mini muffin pan for bite-sized treats; adjust the bake time accordingly.
- Cereal brands: Either name-brand Fruity Pebbles or a similar generic cereal will work.
- Health swap: Replace the oil with applesauce to lower fat content if desired.
How to make Fruity Pebbles cupcakes
- Step 1: Preheat the oven to 350°F and line two cupcake pans with liners.
Step 2: In a large mixing bowl combine the cake mix, water, vegetable oil (or applesauce) and eggs. Mix until smooth.
Step 3: Gently fold in 1 cup of Fruity Pebbles with a spatula so the cereal stays intact and distributes evenly.
Step 4: Fill each liner about 3/4 full. Bake for 18–21 minutes, or until a toothpick inserted into the center comes out clean. Transfer to wire racks to cool completely.
Step 5: While cupcakes cool, make the frosting. Beat the softened butter and powdered sugar until smooth and combined.
Step 6: Add the milk and clear vanilla extract, then beat 1–2 minutes more until the frosting is light and fluffy.
Step 7: Finely crush 1/2 cup Fruity Pebbles (food processor or sealed bag + rolling pin). Fold the crushed cereal gently into the frosting, pipe onto cooled cupcakes, and top with additional cereal for garnish.
FAQs
Store leftover cupcakes in an airtight container at room temperature for up to one week. If you prepare cupcakes in advance, wait to add the cereal garnish until just before serving to keep it crunchy.
Yes. You can freeze unfrosted cupcakes for up to three months. Thaw overnight in the refrigerator and bring to room temperature before frosting. Freezing frosted cupcakes is not recommended if you want the cereal topping to stay crisp.
Tips and Tricks
- Crush the cereal finely: For smooth piping, be sure the cereal is finely pulverized before adding it to the frosting.
- Don’t overfill liners: Filling liners about 3/4 full prevents spills and helps the cupcakes rise evenly.
- Fold gently: Mix the cereal into the batter by hand to avoid crushing it and to keep texture.
- Cool completely: Allow cupcakes to cool fully before frosting so the buttercream doesn’t melt.
- Use clear vanilla: Clear vanilla extract keeps the frosting color bright and prevents any yellow tint.
