Fruity Pebbles Frosting with Ermine Base

You know that feeling when you dunk your spoon into a bowl of Fruity Pebbles and get hit with that sweet, nostalgic milk at the bottom? That rainbow blast of flavor? That’s exactly what this Fruity Pebbles Frosting with Ermine Base brings to the table—but in a silky, pipeable form that makes your baked goods shine.

Let me be clear: this isn’t your average sugar bomb of a buttercream. Nope. We’re talking a lighter, less cloying frosting that still packs a flavor punch. The ermine method gives you a smooth, custard-like base, while cereal milk infuses it with that childhood magic.

What Makes It Different?

Flavor Profile: Fruity, Creamy, and Balanced

• Cereal milk gives it that unmistakable Fruity Pebbles essence
• Subtle sweetness compared to American buttercream
• Smooth, custardy texture

Why Choose Ermine Over Buttercream?

• Less sweet (seriously, you won’t feel like your teeth are under attack)
• Holds its shape beautifully
• Feels light, not greasy

Ingredients

Cereal Milk

• 2 cups Fruity Pebbles
• 4 cups whole milk (or non-dairy alternative)

Frosting Base

• 1 cup cereal milk (from above)
• 1/4 cup all-purpose flour
• 2/3 cup granulated sugar
• 1 cup unsalted butter (softened)
• 1 tsp vanilla extract
• Pinch of salt (omit if using salted butter)
• Optional: 1/2 cup crushed Fruity Pebbles (for folding in or decorating)

Instructions

Step 1: Make the Cereal Milk

• Pour the Fruity Pebbles into a large mixing bowl and cover with the milk.
• Let it steep for 20–30 minutes so the milk absorbs all that vibrant, fruity flavor. You’re essentially making a cereal tea.
• Once time’s up, strain the mixture through a fine mesh sieve into a clean bowl or container. Don’t press on the cereal—it’ll make the milk gritty.
• Set aside 1 cup for the frosting and chill the rest for other uses (like lattes or milkshakes).

Step 2: Cook and Cool the Roux

• In a medium saucepan, combine 1 cup cereal milk, flour, sugar, and a pinch of salt.
• Whisk constantly over medium heat until it thickens into a pudding-like consistency, about 3–5 minutes. Watch for bubbles and keep stirring so it doesn’t scorch.
• If it looks lumpy, strain through a fine mesh sieve into a shallow dish.
• Press plastic wrap directly onto the surface to prevent skin from forming.
• Let it cool completely to room temp. (You can speed this up in the fridge.)

Step 3: Whip the Frosting

• Beat softened butter in a stand mixer or with a hand mixer until it’s pale, fluffy, and almost doubled in volume (3–5 minutes).
• Slowly add the cooled roux, one spoonful at a time, beating well between each addition to avoid splitting.
• Once fully incorporated, beat in vanilla extract and another pinch of salt if desired.
• For added texture and crunch, gently fold in crushed Fruity Pebbles at the end. Just don’t overmix—they’ll soften if left too long.

Tips & Tricks

• Don’t press the cereal when straining milk. It clouds the flavor.
• Cool the roux fully before combining. Warm roux = melted butter = disaster.
• Whip that butter well. You want it light and airy before adding anything else.
• Want extra cereal crunch? Fold in the Fruity Pebbles right before using.

Storage

• Store in airtight container in the fridge for up to 1 week
• Freeze for up to 2 months
• Re-whip at room temperature until fluffy before use

Serving Ideas

• Slather on vanilla cupcakes for a pop of nostalgia
• Pair with funfetti cake to double down on the birthday vibes
• Use in cookie sandwiches for a cereal milk twist
