Confetti Cookies

This is a really basic cookie recipe using boxed cake mix – it’s perfect when you want something colorful without making frosting. The sprinkles bake right into the dough so they won’t fall off.

Ingredients (~35 cookies)

  • 1 (15.5 ounce) box confetti cake mix
  • 1 1/2 tsp baking powder
  • 3 eggs
  • 3/4 cup butter, softened (1 1/2 sticks)
  • 1 1/2 tsp vanilla extract
  • 3/4 cup rainbow sprinkles

Preheat Oven and Prep Baking Sheets

Get your oven to 350F and line three baking sheets with parchment paper.

You’ll need the extra space since this makes more cookies than the original.

Mix the Dough

In a large bowl, whisk together the cake mix and baking powder first.

Add the softened butter, eggs, and vanilla extract. Using an electric hand mixer, beat until everything comes together – it’ll look like thick cake batter at first.

The mixture will be pretty sticky compared to regular cookie dough since you’re working with cake mix.

Fold in the Sprinkles

Gently fold in the rainbow sprinkles with a spoon or spatula.

Don’t overmix here or the sprinkles will start to bleed color into the dough.

Scoop and Bake the Cookies

Using a medium cookie scoop (about 1 1/2 tablespoons), scoop the dough onto your prepared baking sheets.

Space them about 2 inches apart – they’ll spread a bit but not too much.

Bake for ~12 minutes or until the edges are lightly golden. The centers might look slightly underdone but they’ll finish cooking on the hot pan.

Let them cool completely on the baking sheet before moving them – they’ll be soft when hot but will firm up as they cool.
