Ingredients:

  • 1/2 cup (113g) unsalted butter, softened
  • 3/4 cup (150g) granulated white sugar
  • 3/4 cup (165g) packed light brown sugar
  • 1 large (50g) egg, room temperature
  • 1 tsp (5ml) vanilla extract
  • 2 1/4 cups (280g) all-purpose flour
  • 1 tsp (5g) baking soda
  • 1/2 tsp (3g) salt
  • 2 tsp (10ml) blue gel food coloring
  • 10 oz (280g) Oreo cookies, roughly chopped
  • 1/2 cup (90g) M&Ms
  • 1/2 cup (85g) white chocolate chips

Instructions:

  1. Preheat oven to 350°F (175°C). In a large bowl, beat the softened butter with both white and brown sugars on medium-high speed for 2–3 minutes until the mixture looks light, fluffy, and pale.
  2. Stir in the egg, vanilla extract, and blue gel coloring until the batter is a uniform, vibrant blue.
  3. In a separate bowl, whisk together the flour, baking soda, and salt.
  4. Turn the mixer to low and gradually add the dry ingredients, stopping the mixer the second the last streak of flour disappears to avoid overmixing.
  5. Fold in the chopped Oreos, M&Ms, and white chocolate chips using a spatula.
  6. Scoop rounded mounds of dough onto a parchment-lined sheet, spacing them 2 inches apart.
  7. Press a few extra Oreo chunks and M&Ms into the tops of the dough mounds.
  8. Bake for 10–12 minutes; remove when the edges are just set and the centers still look slightly underbaked.
  9. Transfer the cookies to a wire rack immediately to cool and firm up.
