Instructions

In a medium bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt. Set aside.

In the bowl of a stand mixer fitted with a paddle attachment, cream together the butter and peanut butter on medium speed for 2-3 minutes.

Add the sugars and continue beating for 2-3 more minutes until light & fluffy.

Beat in the egg, egg yolk, and vanilla until fully combined.

Add the dry ingredients and mix on low speed until just combined.

Lastly, fold in the oats, m&ms, and chocolate chips with a rubber spatula.

Cover the bowl and place in the fridge for at least one hour or overnight.

Once the dough has chilled, preheat the oven to 350 degrees F (180 degrees C) and line two baking sheets with parchment paper.

Use a 3 tablespoon cookie scoop to portion the cookie dough onto a small parchment lined baking sheet.

Freeze the cookie dough for 15 minutes.

Place the cookie dough on the prepared baking sheets about 2 inches a part, and top with more oats, m&ms, and chocolate chips as desired.

Bake the cookies for about 12 minutes.

Allow cookies to cool completely on the baking sheet and enjoy!

Tips & Tricks (5)

Brown Your Butter First 🧈
Toast the unsalted butter in a saucepan until golden and nutty before creaming with sugars—this adds deep, complex flavor that elevates the entire cookie.
Chill Dough Before Baking ❄️
Refrigerate the dough for at least 2 hours (or overnight) to prevent spreading and ensure thick, chewy cookies with defined edges rather than flat discs.
Use Cornstarch for Softness 🌾
The cornstarch in this recipe reduces gluten development and absorbs moisture—don't skip it, as it's essential for achieving that signature soft, cake-like texture.
Separate Your Chocolate Mix 🍫
Add chocolate chips and M&Ms in the last 30 seconds of mixing to prevent them from breaking down and to maintain distinct pockets of melting chocolate throughout each bite.
Underbake Slightly for Chewiness ⏱️
Remove cookies from the oven when the edges are set but the center still looks slightly underdone—they'll continue cooking on the hot pan and set into perfect chewy cookies.
