Ditch the fancy decorating - these easy Peanut Butter Cup Eyeball Cookies are easy to make with the kids! After baking, simply press a miniature white peanut butter cup and M&M into the top of each one for a spooky (but cute!) Halloween cookie idea.
In a large bowl, cream together ¾ cup butter, softened, 1 cup peanut butter, 1 cup brown sugar, and 1 cup granulated sugar with an electric mixer on medium speed for 30 seconds. Add in 1 teaspoon vanilla extract and 2 large eggs and continue to mix for 10 seconds.
Add 1 ½ teaspoons baking soda and mix on low speed for 10 seconds. Add 2 ½ cups all-purpose flour and continue to mix until all flour is incorporated.
Scoop & roll dough into 1 tablespoon sized balls and place each in a greased, mini muffin tin.
Bake at 350℉ for 8 minutes. Remove from oven, and immediately press one mini Reeses peanut butter cup into the center of each cookie.
After a few minutes, the chocolate of the peanut butter cup will start to melt. Once this happens, gently press a green M&M into the top of each one with the "M" logo side facing down.
Place pan in refrigerator for 10-15 minutes to help the chocolate re-harden.
Once fully cooled, use a black edible food pen to draw a dot onto the top of each M&M for the pupil.
Allow to cool before removing from the cookies from the pan.
If not serving immediately, store in an airtight container for up to 5 days or freeze for long-term storing.
