Monster Cookies {Oats, Peanut Butter, M&M's, Chocolate}

If you want a crowd-pleaser.  If you want a cookie to share at a party.  If you want to take some cookies to work...

Make this monster cookie.  

This is the cookie I think about when I think about childhood. Well, aside from my mom’s chocolate chip cookies. We made these monster cookies all the time. The smell of the dough alone brings back memories. Holidays, parties or just because.

These are chewy, sweet and oh-so-addicting. And you know what? It’s okay to treat yourself once and awhile. Food is also memories and each recipe has a story.

Monster Cookies

  • 1 cup white sugar

  • 1 cup dark brown sugar

  • ½ cup unsalted butter, softened

  • 1 cup creamy peanut butter

  • 2 teaspoons vanilla extract

  • 3 large eggs

  • 4 ¼ cups quick cooking oats

  • ½ cup whole-wheat pastry flour or all-purpose flour

  • 2 tsp. baking soda

  • pinch of salt

  • 1-2 cups candy coated chocolate (M&M’s)

  • 1 cup semi-sweet chocolate chips (you can also use milk chocolate chips)


  1. Cream the butter and the sugars together until well combined. Add in the egg, vanilla and peanut butter and mix until combined.

  2. Slowly add in the baking soda, salt, oats and flour until combined. Stir in M&M’s and chocolate.

  3. On a baking sheet lined with parchment paper, scoop out large tablespoons of dough.

  4. Bake at 350 degrees for about 9-10 minutes, or until the edges are just golden and the middle seems underdone (they will continue to bake as they rest on the pan when you take them out of the oven). Rotate the pans halfway through the baking time. Then take them out and let sit on the pan for about 5 minutes. Remove and let cool on a wire rack completely.

  5. Store in airtight container.
