Chewy Monster Cookies (Peanut Butter Oat Recipe)
My Monster Cookie recipe creates scrumptious chewy cookies, and they’re jam-packed full of chocolate and peanut butter flavor!
Ingredients
- 1/2 cup unsalted butter softened but still cold
- 1/2 cup granulated sugar
- 1/2 cup packed light brown sugar
- 1/2 cup creamy peanut butter
- 1 large egg
- 1/2 teaspoon vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup old fashioned rolled oats not instant
- 1 cup M&Ms plus extra to top cookies
- 1/2 cup mini semi sweet chocolate chips
Instructions
- Preheat the oven to 300°F. and line a cookie sheet with parchment paper. *See Notes
- Using an electric hand mixer or stand mixer fitted with a beater attachment, cream together butter, white sugar and brown sugar in a mixing bowl.
- Add the peanut butter, egg, and vanilla, and mix well on high speed to combine.
- Reduce speed to low and add in flour, baking soda, and salt. Mix just to combine but don’t overmix or your cookies will be tough and dry.
- Using a wooden spoon or silicone mixing spatula, fold in rolled oats, 1 cup M&Ms, and mini chocolate chips.
- Using a 3-tablespoon cookie scoop, portion out the dough and arrange the balls about 2 inches apart on the prepared cookie sheet.
- Bake for 20-22 minutes, or until the edges start to brown and the center is soft.
- Remove cookies from the oven and while still warm, sprinkle with extra M&Ms (optional).
- Let the cookies cool on the cookie sheet for 20-30 minutes. This allows the center and chocolate to set. If you prefer, serve while warm and gooey.
Notes
A 3-tablespoon cookie scoop makes cookies that are a little bit larger than traditional cookies. For this reason, they need to bake at a lower temperature for a longer period of time. Otherwise, they’ll burn on the outside before the inside is cooked.
If you prefer to use a traditional 2-tablespoon sized cookie scoop, increase oven heat to 350°F. and bake the cookies for 12-15 minutes.
