How to Make Monster Cookies for Valentine’s Day
Jump to RecipeSTEP 1 Preheat the oven to 350 degrees F and line a couple of baking sheets with parchment paper or silicone mats. Using a stand mixer or a large bowl with beaters, mix the peanut butter, brown sugar, granulated sugar, and butter. Then, beat in the vanilla extract and eggs until smooth and combined.


STEP 2 Add the oats and baking soda and mix well. Fold in the chocolate chips and M&M’s using a spatula.


STEP 3 Place 2 tablespoons of dough on the prepared baking sheets and add a few M&M’s to the top, if you’d like. Be sure to leave space between each cookie dough ball as they will spread a bit. Bake the cookies for 10 minutes.

STEP 4 Remove the cookies from the oven and allow them to cool on the pan for 5 minutes before transferring them to a wire rack to finish cooling.

Tips & Tricks
- The cookies may not look done after baking for 10 minutes but they are and will set more as they cool so don’t overbake them!
- You can also substitute 1/2 cup of Biscoff Cookie spread for 1/2 cup of the peanut butter used in this recipe.
- You can freeze the cookie dough by making dough balls- rolling 2 tablespoons of dough- and placing the balls of dough in a freezer-safe container. You can bake the cookie dough from frozen by adding 2-3 minutes to the baking time. Wrap baked cookies in plastic wrap or place them in a freezer-safe container and freeze for up to three months.
- To make Christmas Monster Cookies swap out the red and pink M&M’s for red and green. You can create more festive cookies for other holidays or occasions with red, white, and blue M&M’s for the Fourth of July or orange, green, and purple M&M’s for Halloween. Use the colors you like to bring more cheer to your special days.
