Monster Cookies are so nostalgic for me. They remind me of being in my mom’s kitchen as a kid and the thrill of being served a huge, colourful cookie. I have been wanting to share a recipe for Monster Cookies for a while now and have tried many recipes. The things that I love about this recipe are that they are: 1. soft & chewy, 2. quick & easy to make, 3. use basic ingredients, 4. DELICIOUS.
I have adapted this recipe from Julie Van Rosendaal’s Peanut Butter Oatmeal Chocolate Chunk Cookies from her new cookbook called Cookies I have Loved. Her cookbook is full of nostalgic, and approachable cookie recipes which I love!
Monster Cookies
Soft and chewy peanut butter oatmeal cookies with chocolate chips and M&Ms
Servings: 20 cookies
Ingredients
- ½ cup butter, softened
- ½ cup peanut butter (not natural)
- 1 cup brown sugar, lightly packed
- 1 large egg
- 2 teaspoons real vanilla extract
- 1 cup all-purpose flour
- 1 cup oats (I prefer quick oats but large flake are fine too)
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 1 cup chocolate chips (semi-sweet or dark)
- ½ cup M&Ms*, plus more for pressing in tops
Instructions
- Preheat oven to 350°F and line baking sheets with parchment paper.
- In a large bowl, beat together butter, peanut butter, and brown sugar using an electric mixer. Once the mixture is creamy, add the egg and vanilla and beat until combined.
- Add the flour, oats, baking soda, and salt and mix on low speed until combined. Add the chocolate chips and M&Ms and mix on low speed until chocolate is evenly distributed in the cookie dough.
- Using a large cookie scoop (about 3 Tablespoons*), scoop dough onto prepared baking sheets, spacing a couple inches apart. Press a couple extra M&Ms in the tops of the cookie dough balls.
- Bake for 12-15 minutes or until edges of cookies are set and beginning to turn golden. Centres should still be soft and slightly under-baked. Let cool for 5 minutes on baking sheets, then remove to cool completely on wire racks.
Notes
- M&Ms – I used mini M&Ms but regular size is great too
- I used a 3 Tablespoon cookie scoop which made a generous-sized cookie, but if you want an extra-large cookie then use a 1/4 cup measuring cup to scoop dough. You may have to add a couple extra minutes to baking time if you make them larger.
