Birthday Cake Rice Krispie Treats

The classic Rice Krispie Treat recipe is outdated. It’s about time these guys received a much-needed makeover. This is an awesome idea that I came up with while on vacation. I added in some cake mix, sprinkles and a layer of frosting- it turns the classic recipe into a treat that is perfect for birthdays!

Rainbow sprinkles, or “jimmies”, are my Mom’s favorite topping in the entire world. I figured that if she likes them on soft serve ice cream, she’ll love them in Birthday Cake Rice Krispie Treats!  (I was right… she loved them!)

Calories 558 kcal


  • 6 tablespoons (¾ stick) butter, divided
  • two 10-ounce packages marshmallows (or 8 cups mini marshmallows), divided
  • 1 cup white cake mix, divided
  • 1 cup rainbow sprinkles, divided
  • 12 cups Rice Krispies, divided
  • 1 to 1½ cups white frosting


  • You're going to make two batches of Krispie Treats, then you can assemble this dessert.
  • Make the first batch:  Spray a 13x9 inch pan with nonstick spray.  In a large pot, melt the butter and add the marshmallows.  Stir over low heat until the marshmallows are melted.  Remove from heat.  Stir in ½ cup cake mix, ½ cup sprinkles and 6 cups Krispies.  Stir until coated.  Scape into your prepared pan and flatten with clean, lightly buttered hands until you have a nice, even layer.  Let cool for a few minutes, then pop out the whole thing onto a large cutting board.
  • Repeat: Spray the pan and prepare the second batch of treats.  Add a few extra sprinkles on top of the 2nd batch.  Be sure to press down to flatten and make even.
  • Assemble: Spread the frosting onto the first layer.  Remove the 2nd batch of treats and lay them on top of the frosting.  Cut the two-layer treats into 2-inch squares.  These should be served the same day, but keep leftovers in a plastic zip bag at room temperature for up to 2 days for munching.
