Rice Krispies Treats Recipe – Chewy, gooey Rice Krispies treats filled with colored sprinkles, decorated with vanilla frosting, and topped with more sprinkles! An easy, fun, and festive treat for your next celebration!
Today is a big day in our family. Our son, Jake, turns 5! If there was ever a time to share a recipe for Rice Krispies treats loaded with sprinkles and decorated with vanilla frosting, today is the day. My sweet boy only turns 5 once, and I want to celebrate his big day one of the best ways I know how – with sweet treats!
Jake is lucky enough to enjoy three birthday celebrations this year. For two of his celebrations, we will have birthday cake, but for his party with his friends I decided to skip the cake and make big, thick, sprinkle-filled and frosting-topped Rice Krispies treats. What kid would turn down one of these?!
These Rice Krispies treats are chewy and sweet and loaded with gooey marshmallows and colored sprinkles. I like to top each of the squares with a swirl of vanilla frosting, but you can also spread the frosting across the whole tray of Rice Krispies treats. You’ll love serving these at your next birthday party or celebration! Adults and kids will both devour them.
Birthday Sprinkle Rice Krispies Treats
Rice Krispies treats:
- 4 tablespoons unsalted butter
- 10 oz bag plus 2 cups mini marshmallows
- ½ teaspoon pure vanilla extract
- 6 cups Rice Krispies cereal
- ¼ cup plus 1 tablespoon sprinkles, divided
- ½ cup unsalted butter, softened
- 2 cups powdered sugar
- ¾ teaspoon pure vanilla extract
- 3 teaspoons milk, plus more if needed
- pinch salt
- 2 tablespoons sprinkles, for decorating
Rice Krispies treats:
- Line a 9x9 pan with foil and grease the foil. Set aside
- In a large saucepan over low heat, melt butter. Add marshmallows and stir continuously until the marshmallows have melted. Remove from the heat and stir in vanilla extract. Immediately stir in Rice Krispies, stirring until well coated. Scatter ¼ cup of sprinkles over the Rice Krispies and stir just a few times until the sprinkles are dispersed. Do not over-mix or the color from the sprinkles could bleed into the Rice Krispies. Lightly press the mixture into the prepared pan, creating an even layer. Use a piece of waxed paper or buttered fingers to help press the mixture into the pan. Don't press too hard or the treats could get tough. Sprinkle the top with remaining 1 tablespoon of sprinkles. Cool before topping with frosting.
- Using a hand mixer or stand mixer, beat butter until smooth. Add powdered sugar, vanilla extract, milk, and salt and beat on low speed. Increase to medium-high speed and beat for 1-2 minutes, until creamy and fluffy. Add more milk, if necessary, to thin. Spread the frosting across the top of the bars or use a piping bag fitted with a star tip to pipe frosting onto the top of each bar. Decorate with remaining sprinkles.
