Monster Cookies
Fluffy, lighter-than-air peanut butter oatmeal cookies stuffed with mini chocolate chips, M&Ms, rolled oats, and Rice Krispies will be your new family favorite cookie.
Servings 4 dozen cookies
Ingredients
- 2/3 cup unsalted butter, at room temperature
- 1/2 cup creamy peanut butter (I use Skippy)
- 2/3 cup brown sugar, packed
- 1/2 tsp vanilla extract
- 2 eggs
- 1 1/2 cups all-purpose flour
- 1/2 tsp salt
- 1 tsp baking soda
- 1 cup old fashioned rolled oats
- 3/4 cup mini semi-sweet chocolate chips
- 3/4 cup M&Ms
- 1 cup Rice Krispies cereal
Instructions
PREP INSTRUCTIONS
- Preheat your oven to 350F.
- Line four baking sheets with parchment paper and set aside.
BAKING INSTRUCTIONS
- In a large bowl of a stand mixer** cream together the butter, brown sugar, and peanut butter until smooth. Scrape down sides of the bowl as needed.
- Beat in the eggs, one at a time, mixing well between each addition.
- Beat in the vanilla extract.
- In a separate, medium-sized bowl, whisk together the flour, salt, and baking soda.
- Slowly add the flour mixture into the wet ingredients, beating thoroughly in between additions and scraping down thsides of the bowl as needed, until incorporated. Cookie dough will be thick.
- In this order, add the oats, the chocolate chips, the m&ms, and the rice krispies, giving the mixer a quick turn in between each addition to incorporate the mix-ins. You want to add the Rice Krispies last so they don’t break apart in the mixer.
- Scoop Monster Cookies onto prepared baking sheets; you should be able to fit 12 cookies on each sheet since they don’t spread much in the oven.
- Bake Monster Cookies at 350F for 9-10 minutes, or until the bottoms have just started turning brown. The cookies will look underdone, but they will harden as the cool.
- Cool the Monster Cookies on baking sheets for 5 minutes, then transfer to a wire rack to cool completely. Eat within 1-2 days of baking.
Notes
**You can use a hand mixer for this recipe, but a stand mixer works best since the dough gets pretty thick.
