Ingredients

Scale

Dry Ingredients

2 1/2 cups all-purpose flour (325 grams)
2 teaspoons baking powder (10 grams)
1 teaspoon salt (6 grams)
1 tablespoon cornstarch (8 grams)

Wet Ingredients

1 cup unsalted butter (room temperature, 8 ounces)
¾ cup granulated sugar (150 grams)
½ cup brown sugar (105 grams)
½ teaspoon vanilla extract (5 grams)
1 large egg
1 large egg yolk

Add-ins

1 cup rainbow chips (170 grams)
½ cup sprinkles

Instructions

Preheat and Prepare Baking Sheet: Preheat your oven to 375ºF (190ºC) and line a baking sheet with parchment paper to prevent sticking and to ensure easy cleanup.
Mix Dry Ingredients: In a medium-sized bowl, whisk together the all-purpose flour, baking powder, salt, and cornstarch until thoroughly combined. Set this mixture aside.
Cream Butter and Sugars: Using a hand mixer or stand mixer, beat the unsalted butter with the granulated sugar and brown sugar until the mixture is smooth and creamy. This step helps to incorporate air for tender cookies.
Add Eggs and Vanilla: Mix in the vanilla extract, the whole egg, and the egg yolk until the wet ingredients are fully combined and smooth.
Combine Dry and Wet Ingredients: Gradually add the dry ingredient mixture into the wet ingredients in small portions, mixing on low speed first to avoid flour flying, then increasing to medium speed until the dough is fully blended.
Fold in Rainbow Chips and Sprinkles: Using a wooden spoon or rubber spatula, gently stir in the rainbow chips and sprinkles evenly throughout the dough for bursts of color and sweetness.
Form Cookies and Bake: Use a medium cookie scoop to drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading. Bake for 8-10 minutes or until the edges are lightly golden.
Cool Cookies: Remove the baking sheet from the oven and let the cookies cool on it for 5 minutes before transferring them to a wire rack to cool completely, which allows the cookies to firm up without breaking.

Notes

Ensure the butter is at room temperature for easy creaming with the sugars.
If you prefer, substitute rainbow chips with chocolate or white chocolate chips.
For more vibrant sprinkles embedded in the cookie, gently press some additional sprinkles on top of the dough balls before baking.
Store cookies in an airtight container to maintain freshness up to one week.
If you want softer cookies, reduce baking time slightly to about 7-8 minutes.
