Ingredients for Fruity Pebbles Frosting

- ⅓ cup (18 g) + 2 Tablespoons Fruity Pebbles cereal (divided; reserve 2 Tablespoons for garnish)
- ⅓ cup (78 ml) whole milk (or substitute with heavy cream for a richer flavor)
- 4 oz (113 g) white chocolate (chopped into small pieces for easy melting)
- 1 cup unsalted butter (softened to room temperature for smooth mixing)
- 2 cups (250 g) powdered sugar (sifted for a lump-free frosting)
- ⅛ teaspoon salt (to balance the sweetness)
Step-by-Step Instructions
- Soak the cereal: Place ⅓ cup of Fruity Pebbles in a small bowl and pour the milk evenly over it. Let it soak for 20 minutes to infuse the milk with flavor.
- Melt the white chocolate: Chop the white chocolate into small pieces and place in a microwave-safe bowl. Microwave for 30 seconds, stir, then heat in 15-second increments, stirring well in between, until fully melted and smooth. Let it cool until no longer warm but still melted.
- Prepare the butter: In a large mixing bowl, beat the softened butter with an electric mixer until smooth and creamy.
- Combine chocolate and butter: Once the chocolate has cooled, drizzle it into the butter and mix until smooth and well combined.
- Add powdered sugar: Gradually add the powdered sugar, stirring until completely incorporated and the frosting is smooth.
- Incorporate salt: Add the salt and mix well to enhance the flavor.
- Strain the cereal milk: Pour the soaked cereal and milk through a fine mesh strainer into a measuring cup. Use a spatula to press out as much milk as possible, then discard the cereal.
- Add milk to frosting: Measure out 2 Tablespoons of the infused milk and add it to the frosting. Stir on low speed until smooth and fully incorporated.
- Grind remaining cereal: Grind the reserved 2 Tablespoons of Fruity Pebbles into fine crumbs using a food processor or mortar and pestle.
- Mix in cereal crumbs: Add the ground cereal to the frosting and use a spatula to stir until smooth and evenly combined.
- Pipe or spread: Use the frosting immediately to pipe or spread over cooled baked goods. Enjoy the vibrant, fruity flavor!
Perfect Pairings: Serving Suggestions
This Fruity Pebbles Frosting is a vibrant and fun addition to any dessert! Spread it over vanilla or Funfetti cupcakes for a colorful treat, or use it to frost a classic yellow cake for a nostalgic twist. It also pairs wonderfully with sugar cookies or as a dip for fresh fruit like strawberries and bananas. Get creative and let the fruity flavors shine!
Storage Tips: Keep It Fresh
Store your frosting in an airtight container in the refrigerator for up to 5 days. Before using, let it sit at room temperature for about 15 minutes to soften, then give it a quick stir to restore its creamy texture. Pro tip: If you’ve already frosted your baked goods, keep them covered in the fridge to maintain freshness.
Time-Saving Hacks
Short on time? Use pre-melted white chocolate or a white chocolate melting wafer to skip the chopping and microwaving step. You can also grind the Fruity Pebbles in advance and store them in a small container until you’re ready to mix them into the frosting. Every minute saved counts!
Equipment Essentials
To make this recipe a breeze, you’ll need a few key tools: a fine mesh strainer for separating the cereal and milk, a small food processor or blender for grinding the cereal, and an electric mixer for achieving that smooth, creamy texture. If you don’t have a food processor, you can crush the cereal in a sealed bag with a rolling pin—just aim for fine crumbs!
Recipe Variations to Try
Switch up the flavors by using different cereals like Cocoa Pebbles for a chocolatey twist or Trix for a rainbow of colors. You can also swap white chocolate for milk or dark chocolate if you prefer a richer taste. Experiment and make it your own!
