Preheat your oven to 350°F (175°C) and prepare your baking sheet with parchment paper.

Twist apart the Oreo cookies, using the cream-less sides for the recipe.

In a medium mixing bowl, combine softened butter and powdered sugar, and beat until fluffy.

Spread filling on one Oreo half, sandwich it with another half, and repeat for all Oreos.

Melt the chocolate kisses in a microwave-safe bowl until smooth.

Place a melted chocolate kiss on each Oreo sandwich, letting it flow slightly down the sides.

Melt white chocolate chips and drizzle over each cookie.

Sprinkle colorful sprinkles on top before the white chocolate sets.

Cool the cookies on a wire rack before serving.
