- 3/4 cup (170 g) unsalted butter, at room temperature
- 1 cup (200 g) packed light brown sugar
- 1/4 cup (50 g) granulated sugar
- 1/2 cup smooth peanut butter, at room temperature
- 1 large egg, plus 1 egg yolk, at room temperature
- 1 teaspoon vanilla
- 2 1/4 cups (280 g) all-purpose flour, spooned and leveled
- 3/4 cup (60 g) quick oats
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 3/4 cup to 1 cup semi-sweet chocolate chips
- 1/2 cup white chocolate chips
- 1 cup M&M candies
- Heat the oven to 350°F and line two baking sheets with parchment paper.
- Add the butter, brown sugar, granulated sugar, and peanut butter to the bowl of a stand mixer fitted with the paddle attachment. Beat on medium-high speed until the mixture looks creamy and airy, about 3 minutes. Scrape the bowl as needed.
- Mix in the whole egg, then add the egg yolk and blend on low speed until smooth.
- Pour in the vanilla and mix until it disappears into the dough.
- In a separate bowl, whisk the flour, quick oats, baking soda, and kosher salt together.
- Add the dry mixture to the butter mixture a little at a time. Mix just until the dough begins to come together and a few flour streaks remain.
- Take the bowl off the mixer and fold in the M&M candies, semi-sweet chocolate chips, and white chocolate chips with a spatula.
- Scoop the dough onto the prepared baking sheets with a two-tablespoon cookie scoop. For matching cookies, portion each dough ball to 2 ounces.
- Bake for 9 to 11 minutes, until the edges are lightly golden and the centers still look pale and slightly puffed. Halfway through baking, carefully lift and drop the baking sheet to help the cookies settle flatter. Repeat after baking if the tops still look too rounded.
- Let the cookies rest on the baking sheets for 10 minutes, then move them to a wire rack to finish cooling.
