Step 1

Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper. Spread the cake mix across the baking sheet. Bake for 5 minutes, then remove from the oven and let cool.

Step 2

Line a 9×9-inch square baking dish with parchment paper, leaving some of the paper hanging over the edges. Lightly spray with oil.

Step 3

In a large pot, melt the butter over medium-low heat. Add marshmallows. Stir together just until the marshmallows are melted through. It is important to slowly melt them; do not overcook the marshmallows or your rice krispies treats will become hard.

Step 4

Once the marshmallows are melted, immediately remove the pot from heat. Stir in the cake mix, vanilla extract, almond extract, and salt. Mix together to evenly combine.

Step 5

Add rice krispies cereal and 2 tbsp rainbow sprinkles to the pot. Gently fold together, evenly coating all of the cereal.

Step 6

Transfer the mixture to the baking dish. Using a silicone spatula, press it across the dish in an even layer.

Step 7

In a small bowl, add white chocolate chips. Microwave in 30-second intervals, stirring in between, until melted through. Spread on top of the rice krispie treats. Top with the remaining rainbow sprinkles.

Step 8

Set rice krispies aside to cool for one hour. After, slice into 12 or 16 squares. Enjoy!
