Prep Time 10minutes
Cook Time 9minutes
1 1/2cupsall-purpose flour
1/2teaspoonsalt(increase to 1 teaspoon if using unsalted butter)
Heat oven to 350°. Prepare cookie sheets by lining with parchment paper, silpat liner, or spray lightly with cooking spray. Set aside.
In a medium bowl, whisk together the oats, flour, baking soda, and salt.
In a large mixing bowl, beat together the butter, peanut butter, brown sugar, and granulated sugar until creamy and combined well. About 1-2 minutes. Add in the eggs and vanilla extract. Blend until combined.
Mix the oat mixture into the butter mix, on low speed, and gradually increase the speed as needed just until everything is combined well. Add in the halloween m&m's and blend until combined.
Take about 2 tablespoons of dough (I use a cookie scoop for this) and roll it into a ball. When done, the dough balls will look like golf balls. Place 12 dough balls onto the cookie sheet. Bake for 9-11 minutes. *Don't overbake these! They will continue cooking as they cool on the cookie sheet. The cookies should look puffy and not look wet.
Immediately, gently press a few additional m&m's on top of each cookie and two candy eyeballs.
Move the cookie to a cooling rack to cool completely. Store leftovers in a covered container out at room temperature. Leftovers are really good heated in the microwave for a few seconds.
