Ingredients

Cookie Bars

1 Tbsp + 1 tsp rainbow sprinkles, divided $0.86
1 cup sugar $0.34
1 tsp baking powder $0.04
2 cups all-purpose flour $0.33
2 tsp vanilla extract $0.48
1 large egg $0.41
1 stick salted butter + more to grease the pan*, room temperature $0.99
1 cup whole milk $0.27

1 tsp vanilla extract $0.24
2 cups powdered sugar $1.10
2 Tbsp whole milk** $0.01

Instructions

Gather ingredients and preheat your oven to 350℉. Leave both sticks of butter out to reach room temperature. Grease a 9x13” baking dish with cooking spray or a little butter.
Combine 1 Tbsp rainbow sprinkles, sugar, baking powder, and flour in one bowl. Combine 2 tsp vanilla and egg in another smaller bowl.
Mix together dry ingredients in the first bowl and then add softened salted butter. Mix with a hand mixer until combined.
Then, add egg and vanilla mixture.
Once combined, pour in 1 cup milk and mix.
Pour batter into prepared baking dish and smooth it out so it’s level with a spatula.
Bake for 25-30 minutes until the edges are golden brown and a toothpick inserted in the center comes out clean. Let cool completely before frosting.
While your cookie bars are cooling, make frosting by combining softened unsalted butter, 1 tsp vanilla, powdered sugar, and 2 Tbsp whole milk with a hand mixer until smooth.
Frost the cooled cookie bars. I used an offset spatula.
Top with the remaining 1 tsp rainbow sprinkles. Slice and enjoy!

Notes

*You can use cooking spray or butter, whatever you have on hand.

**Heavy cream or half and half also works in place of the whole milk in the frosting.
