Ingredients

Scale
  • 3/4 cup unsalted butter (melted)
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar (packed)
  • 1 large egg (room temperature)
  • 1 large egg yolk (room temperature)
  • 1 teaspoon vanilla extract
  • 1 3/4 cups all-purpose flour
  • 3/4 teaspoon baking powder
  • 1 teaspoon corn starch
  • 1/2 teaspoon salt
  • 10-14 Golden Oreos, roughly chopped (divided)
  • 1/4 cup rainbow sprinkles (plus extra for garnish)

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8 or 9×9 inch pan with parchment paper and spray it with cooking spray. Set aside.
  2. Whisk together the flour, baking powder, and salt in a medium-sized bowl. Set aside.
  3. Beat the melted butter and both sugars on high speed for about 2 minutes until light and fluffy.
  4. Add the egg and egg yolk, one at a time, mixing on medium speed and scraping down the bowl between additions. Add the vanilla extract and mix on low.
  5. Gradually add the dry mixture to the wet ingredients, mixing on low speed just until combined.
  6. Fold in 4 of the chopped Golden Oreos and the sprinkles until evenly distributed.
  7. Pour the batter into the prepared pan and smooth it out. Press the remaining chopped Golden Oreos on top and sprinkle more rainbow sprinkles over the surface.
  8. Bake for 25-30 minutes, or until the center is set and the edges are lightly golden brown.
