Ingredients
For Cereal Milk
- 2 cups Fruity Pebbles cereal
- 4 cups whole milk
For Frosting
- 1 cup cereal milk (prepared 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 into frosting)
Instructions
- Make Cereal Milk: In a large bowl, combine 4 cups whole milk with 2 cups Fruity Pebbles cereal. Stir gently to combine and let it steep for 20-30 minutes, stirring occasionally so the milk absorbs the fruity flavors.
- Strain Cereal Milk: Pour the milk-cereal mixture through a fine mesh sieve or strainer. Gently press the cereal to extract about 1 cup of cereal-flavored milk, but avoid scraping hard to prevent cereal bits from falling into the milk.
- Prepare Roux Mixture: In a medium or large saucepan, whisk together 1/4 cup flour, 2/3 cup sugar, a pinch of salt, and 1 cup of the prepared cereal milk until smooth.
- Cook Roux: Over medium to medium-low heat, continuously stir the mixture for 3-5 minutes as it thickens to a smooth, roux-like texture. Remove from heat once thickened. If lumps form, strain the warm roux through a fine mesh sieve for a smooth finish.
- Cool Roux: Transfer the roux to a heat-safe bowl and cover directly with plastic wrap to prevent a film from forming. Allow it to cool to room temperature by leaving it out for 1-2 hours or chilling in the fridge for 30-40 minutes. It must be cool before proceeding to avoid melting the butter.
- Beat Butter: Using a standing or handheld mixer at medium speed, beat the softened unsalted butter for 3-5 minutes until light and fluffy with a pale yellow color.
- Incorporate Roux: Gradually add the cooled roux mixture to the butter in 2-tablespoon increments, ensuring each addition is fully incorporated before adding more.
- Whip Frosting: Once all roux is incorporated, increase mixer speed to medium-high and beat for an additional 2-3 minutes to achieve a light and fluffy texture.
- Add Flavor and Mix-ins: Mix in 1 teaspoon vanilla extract and an additional pinch of salt. If desired, gently fold in 1/2 cup of crushed Fruity Pebbles cereal for added texture and color.
- Use or Store: The frosting is now ready to spread on your favorite cakes or cupcakes. Enjoy the vibrant fruity flavor and creamy texture!
Notes
- Ensure the roux mixture is fully cooled before mixing with butter to prevent melting and separation.
- If lumps persist after cooking the roux, straining is essential for a smooth frosting.
- You can omit the crushed Fruity Pebbles mix-in if you prefer a smoother frosting appearance.
- The frosting pairs especially well with vanilla or chocolate cakes.
- Store leftover frosting in an airtight container in the refrigerator for up to 3 days; rewhip before use.
