Dry Ingredients:
- 3 cups old-fashioned oats
- 1½ teaspoons baking soda
- ½ teaspoon salt
Wet Ingredients:
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup creamy peanut butter
- 1 cup packed light brown sugar
- ¾ cup granulated sugar
- 3 large eggs
- 2 teaspoons vanilla extract
Mix-Ins:
- 1 cup red M&Ms
- 1 cup white chocolate chips
- 1 cup blue M&Ms
- ½ cup semi-sweet chocolate chips (optional, for extra chocolate)
Instructions
- Preheat your oven to 350°F and line two large baking sheets with parchment paper.
- In a medium bowl, stir together the oats, baking soda, and salt. Set aside.
- In a large mixing bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar until smooth and fluffy. This takes about 2-3 minutes with a hand mixer, or you can do it by hand with a wooden spoon if you’ve got the arm strength.
- Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Pour the oat mixture into the butter mixture and stir until just combined. The dough will be thick.
- Fold in the red M&Ms, white chocolate chips, blue M&Ms, and chocolate chips (if using). Mix until the candy is evenly distributed throughout the dough.
- Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. These cookies spread a bit, so give them room.
- Bake for 10-12 minutes, until the edges are golden but the centers still look slightly underdone. Don’t overbake—they’ll firm up as they cool.
- Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
- Store in an airtight container for up to 5 days, or freeze for up to 3 months.
- Prep Time: 15 minutes
- Cook Time: 10-12 minutes per batch
