Equipment
- Stand Mixer
- 2 Baking sheets
Ingredients
- ½ cup creamy peanut butter
- ½ cup unsalted butter softened
- ½ cup brown sugar packed
- ½ cup granulated white sugar
- 1 large egg plus egg yolk
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- ½ teaspoon salt
- ¾ cup old-fashioned oats
- 1 cup all-purpose flour
- ¾ cup red and green holiday candies like M&Ms
- ½ cup semi-sweet chocolate chips
- ½ cup white chocolate chips optional
- ½ cup Holiday sprinkles optional
Instructions
- Preheat the oven to 350°F (175°C). Line two large baking sheets with parchment paper.
- In the bowl of your stand mixer fitted with a paddle attachment or large bowl with a hand mixer, beat peanut butter, butter, brown sugar, and granulated sugar on high speed until smooth and creamy.
- Add the egg and egg yolk, then mix in the vanilla extract.
- In another small bowl, whisk together the baking soda, salt, oats, and flour.
- With the mixer on low speed gradually add the dry ingredients to the wet mixture, mixing until just combined.Do not over mix.
- Fold in the m&ms, chocolate chips, and optional white chocolate chips and sprinkles.
- Using a large cookie scoop (about 2 tablespoons), drop dough balls onto the prepared baking sheets, spacing them 2 inches apart.Optionally, top each cookie with more m&ms and chocolate chips.
- Bake for 10–12 minutes, until the edges are golden. Centers may appear slightly underdone; they’ll set as they cool.
- Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
- For the best results and a chewy texture, use a creamy, non-natural peanut butter (like Skippy or Jif). Natural peanut butter can be too oily and make the cookies spread.
- This recipe is very flexible! Feel free to swap the chocolate chips and M&Ms for your favorite mix-ins like holiday-themed sprinkles, chopped pretzels, or even toffee bits.
- Be sure to use old-fashioned rolled oats, not instant or quick oats. The larger flakes give the cookies their signature chewy texture.
- The dough is meant to be thick and sticky! Chilling is not required, but it can help prevent spreading if your kitchen is war
