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:
- 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.
- Stir in the egg, vanilla extract, and blue gel coloring until the batter is a uniform, vibrant blue.
- In a separate bowl, whisk together the flour, baking soda, and salt.
- 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.
- Fold in the chopped Oreos, M&Ms, and white chocolate chips using a spatula.
- Scoop rounded mounds of dough onto a parchment-lined sheet, spacing them 2 inches apart.
- Press a few extra Oreo chunks and M&Ms into the tops of the dough mounds.
- Bake for 10–12 minutes; remove when the edges are just set and the centers still look slightly underbaked.
- Transfer the cookies to a wire rack immediately to cool and firm up.
