Ingredients

Scale

Dry Ingredients

180 g all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt

Wet Ingredients

115 g unsalted butter (melted)
125 g granulated sugar
1 large egg (room temperature)
1 tablespoon clear vanilla extract

Add-ins

100 g white chocolate (roughly chopped, plus extra for topping)
50 g rainbow sprinkles (plus extra for topping)

Instructions

Prep: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper and set it aside to prepare for baking.
Mix Dry Ingredients: In a small bowl, whisk together the flour, baking powder, baking soda, and salt until evenly combined. Set this mixture aside for later.
Mix Wet Ingredients: In a large mixing bowl, combine the melted unsalted butter and granulated sugar using a hand mixer or whisk until the mixture is well blended. Add in the room temperature egg and clear vanilla extract, then whisk again until fully incorporated.
Combine Wet and Dry Mixtures: Gradually add the dry ingredient mixture to the wet mixture, stirring until almost combined. Fold in the roughly chopped white chocolate and rainbow sprinkles using a spatula to avoid overmixing and to maintain a tender cookie texture.
Scoop Dough: Use a cookie scooper to portion the dough, placing scoops onto the prepared baking sheet. Leave approximately 2 inches between each dough ball to allow room for spreading during baking.
Bake Cookies: Bake in the preheated oven for 11-12 minutes or until the edges are set but the centers remain soft. During the last 2 minutes of baking, gently press additional white chocolate chunks on top of each cookie and sprinkle with extra rainbow sprinkles to add a decorative touch.
Cool the Cookies: Once out of the oven, optionally swirl the cookies with a round cookie cutter slightly larger than the cookies to smooth the edges into perfect rounds. Allow the cookies to cool on the baking sheet for about 10 minutes to firm up before transferring them to a wire rack to cool completely.

Notes

Using clear vanilla extract maintains the bright colors of the sprinkles without tinting the dough.
Room temperature egg helps create a smooth batter and better texture.
Do not overmix the dough once the dry ingredients are added to keep cookies tender.
Pressing extra chocolate and sprinkles on top near the end of baking adds vibrant, melty toppings and festive appearance.
Allow cookies to cool on the baking sheet first to avoid breaking as they are delicate when warm.
