Save to Pinterest Create a vibrant, playful topping by whipping softened butter with powdered sugar, milk, and vanilla until fluffy. Fold in colorful Fruity Pebbles cereal for that signature crunch and fun appearance. Spread or pipe onto your favorite baked goods and garnish with extra cereal just before serving. This American-style butter frosting comes together in just 10 minutes and yields enough for 12 cupcakes or one 9-inch cake. For best results, apply the cereal garnish right before serving to maintain maximum crunchiness.
My kitchen counter looked like a rainbow exploded one Saturday morning when my niece challenged me to make the most ridiculous frosting I could dream up.
I brought a batch to a potluck and watched three grown adults skip the main course entirely just to hover near the dessert table.
Ingredients
- Unsalted butter (1/2 cup, softened): Room temperature butter is nonnegotiable here because cold butter leaves lumps that no amount of mixing can fix.
- Powdered sugar (2 cups, sifted): Sifting prevents those awful little sugar bombs that catch in your piping tip at the worst moment.
- Whole milk (2 tbsp): Whole milk gives the richest texture but any milk works in a pinch.
- Vanilla extract (1 tsp): A small splash rounds out the sweetness and keeps the frosting from tasting one dimensional.
- Fruity Pebbles cereal (1 cup, divided): Three quarters goes into the frosting and one quarter gets saved for a crunchy garnish that makes people smile.
Instructions
- Whip the butter:
- Beat the softened butter in a large mixing bowl with a hand mixer or stand mixer until it turns creamy and pale, roughly two minutes.
- Add sugar gradually:
- Pour in the sifted powdered sugar one cup at a time on low speed so you do not end up wearing a cloud of white dust.
- Make it fluffy:
- Add the milk and vanilla extract then beat on medium high for two to three minutes until the frosting is smooth and light as air.
- Fold in the fun:
- Use a spatula to gently fold three quarters of a cup of Fruity Pebbles into the frosting until the color streaks look like a sunset.
- Spread or pipe:
- Apply the frosting to completely cooled cupcakes or cakes using whatever method makes you happy.
- Garnish at the last second:
- Scatter the remaining quarter cup of cereal on top right before serving so every piece stays audibly crunchy.

Making It Your Own
Vegan butter swaps in seamlessly for a dairy free version and honestly most people cannot tell the difference.
Fixing Consistency Issues
If the frosting feels too loose add powdered sugar one tablespoon at a time until it holds its shape without slouching.
Serving and Storing
Store any leftover frosting in an airtight container in the refrigerator for up to three days but always bring it back to room temperature and rewhip before using.
- A piping bag with a large open star tip shows off the colorful cereal pieces beautifully.
- This frosting pairs especially well with vanilla or white cake so the colors can really pop.
- Always check Fruity Pebbles packaging for allergen information since processing facilities vary by brand.

Recipe FAQs
- → Can I make this frosting ahead of time?
-
Yes, prepare the frosting base up to 2 days in advance and store in an airtight container in the refrigerator. Bring to room temperature and re-whip before using. Add the cereal garnish just before serving for optimal texture.
- → What other cereals work well in this frosting?
-
Try Fruity Pebbles' cousin Cocoa Pebbles for a chocolatey version. Crushed Captain Crunch, Fruit Loops, or colorful sprinkles also provide excellent crunch and visual appeal.
- → How do I achieve the right frosting consistency?
-
The frosting should hold its shape when piped. If too thin, add powdered sugar one tablespoon at a time. If too thick, incorporate milk one teaspoon at a time until you reach spreadable perfection.
- → Is this frosting suitable for piping decorations?
-
Absolutely! The cereal pieces may slightly affect smooth piping, so use a large open star tip (like 1M or 2D) for best results. The texture creates beautiful rustic swirls with hidden colorful crunch.
- → Can I make this dairy-free?
-
Replace unsalted butter with vegan butter sticks and use plant-based milk. Note that Fruity Pebbles contain gluten, so this version remains gluten-containing but dairy-free suitable.
- → Why add cereal garnish right before serving?
-
Fruity Pebbles soften when exposed to moisture from the frosting. Sprinkling them just before serving preserves their signature crunch and prevents soggy cereal pieces.
