Ingredients
Method
Preheat oven to 350°F and line two baking sheets with parchment paper.
Brown the butter in a saucepan over medium heat until golden and fragrant. Cool for 10 minutes.
Whisk browned butter, brown sugar, granulated sugar, and peanut butter until smooth.
Mix in the egg and vanilla extract until fully combined.
In a separate bowl, whisk together flour, baking soda, salt, and oats.
Add dry ingredients to wet ingredients and stir until just combined.
Fold in chocolate chips, white chocolate chips, and M&M candies.
Scoop large portions of dough onto prepared baking sheets.
Bake for 10–12 minutes or until edges are lightly golden.
Cool on baking sheets for 5 minutes before transferring to a wire rack.
Notes
Store in an airtight container for up to 5 days. The dough can be refrigerated for up to 48 hours before baking. For thicker cookies, chill the dough for 30 minutes before baking.
