A peanut butter oatmeal cookie topped with chocolate chips and M&Ms for a giant monster cookie pizza.
My mom is obsessed with M&M’s. So on Mother’s Day I was asking Kayden what her Nana’s favorite food was and she said pizza and M&M’s (totally true), which got me thinking, I don’t have any M&M recipes on my blog! But I fixed that and have a few more M&M recipes up my sleeve that will be coming soon.
This monster cookie pizza starts with a peanut butter and oatmeal cookie. The edges of the cookie are crispy while the inside is soft and chewy (my favorite part).
Once the cookie is baked, you will top with M&M’s and chocolate chips! But feel free to add any other toppings you might like. Love nuts? Add them! Peanut butter chips? Yum! Crushed Oreos? Send me a piece!
I loved eating this cookie right out of the oven all melty and warm (yup, just minutes after I took these pictures) but it can be eaten cool too if you have the willpower to let it sit for that long 😉
- 1 cup all purpose flour
- ½ teaspoon baking soda
- 6 tablespoons butter, softened
- ½ cup brown sugar
- ¼ cup granulated sugar
- ¼ cup creamy peanut butter
- 1 large egg
- 1 teaspoon vanilla
- ¾ cup old fashioned oats
- ¾ cup M&M's
- ¾ cup milk chocolate chips
- Preheat oven to 350 degrees. Spray a 9 inch pie pan with non-stick cooking spray and set aside.
- In a medium bowl, mix together the flour and baking soda. Set aside.
- In a stand mixer, combine the butter, brown sugar, granulated sugar, and peanut butter. Mix very well, approximately 2-3 minutes. Add the egg and vanilla and mix well, scraping the sides of the bowl. Add the flour mixture and stir until just combined. Add the oats and stir until just combined.
- Using a wooden spoon, press the dough to the bottom of the prepared pie ban. Bake for 15-18 minutes or until edges are slightly browned.
- Remove from oven and top with chocolate chips and M&M's. Allow the cookie to cool slightly before serving.
