Prep: 15 minutes
Cook: 20 minutes
Total: 35 minutes
Servings: 20 people



  • Preheat the oven to 325°F
  • In a bowl whisk together flour, soda, powder and salt. Set aside.
  • Cream butter and sugar only just until a smooth paste forms. This is critical for thick and chewy cookies.
  • Beat in the egg, scraping down the sides of the bowl and really making sure it is incorporated. Add the peanut butter and beat until smooth.
  • Reduce the speed to low and slowly add the dry ingredients a bit at a time. I never wait until it all incorporates before adding more, but you don’t want to overwhelm the batter either. Easy does it!
  • Once all the flour has mixed in, add the chocolate chips, oats and mini M&M’s.
  • Press it into a cast-iron skillet. If yours is nicely seasoned, you don’t even need to spray it. If you don’t know, just give it a little spritz with nonstick cooking spray.
  • Pop in preheated oven and bake until golden brown around the edges and the top. It will take 20-22 minutes.
  • Cool and then slice and enjoy. Or just gather your besties, pull it from the oven, and pile it high with ice cream and dig right in.
