Description
These Monster Cookies are chewy, peanut buttery treats filled with oats, M&Ms, and chocolate chips. They are easy to make and perfect for satisfying a sweet craving.
Ingredients
Scale
- 1 cup (255g) creamy peanut butter (natural or regular works fine)
- 1/4 cup unsalted butter, room temperature
- 1/2 cup (100g) packed light brown sugar
- 1/2 cup (100g) granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 3 cups (260g) quick-cooking oats
- 1 cup M&Ms (regular or mini size)
- 1 cup semi-sweet chocolate chips
Instructions
- Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats for easy cleanup.
- In a large bowl, combine the peanut butter and softened butter. Use an electric mixer on medium speed to beat until smooth and well combined, about 1 minute. Add both sugars and continue beating until the mixture is light and fluffy, about 2 minutes more.
- Add the eggs one at a time, mixing well after each addition. Beat in the vanilla extract until fully incorporated. The mixture should be smooth and creamy.
- Sprinkle the baking soda and salt over the wet mixture. Mix until combined. Add the oats one cup at a time, mixing at low speed between additions to prevent oats from flying everywhere.
- Gently fold in the M&Ms and chocolate chips using a rubber spatula.
- Using a 2-tablespoon cookie scoop or spoon, drop dough onto the prepared baking sheets, spacing cookies about 2 inches apart.
- Bake for 10-12 minutes until the edges are set but the centers still look slightly underdone.
- Allow cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely. They will firm up as they cool.
Notes
- For gluten-free Monster Cookie variations, ensure your oats are certified gluten-free.
- Mix-ins can be changed based on preferences, try butterscotch chips, chopped nuts, or white chocolate chunks.
- For longer storage, wrap cooled cookies individually and freeze for up to 3 months.
