Halloween Candy Overload Cookies

If you love Monster Cookies, then you will love these cookies. Halloween Candy Overload Cookies are similar to monster cookies, made with soft peanut butter and oatmeal cookies. However, this recipe is not limited to the traditional chocolate chips and M&M’s.

Halloween Candy Overload Cookie Recipe

I love that you can use most candies in this recipe! So, get out that bag of leftover candy and get baking!

Ingredients (full recipe below)

  • Candy (Reese’s peanut butter cups, Twix, Hershey’s chocolate, Milk Duds, KitKat, etc.)
  • Brown sugar
  • Unsalted butter
  • Peanut butter
  • Egg
  • All-purpose flour
  • Baking soda
  • Cornstarch
  • Baking powder
  • Salt
  • Old-fashioned oats–Also known as rolled oats, old-fashioned oats cook faster than steel-cut oats and hold their shape a little better. Try to stay away from using instant oats in this recipe; the cookies will not have the same texture.

How to Make the Cookies

To make the cookies, line a baking sheet with parchment paper and preheat the oven to 350°F. Whatever candies you are using (I like to mix and match a variety of kinds), be sure to chop them into small pieces. Set those aside.

  1. Cream together the brown sugar, butter, and peanut butter.
  2. Mix in the egg on low speed.
  3. In a separate bowl, combine the flour, baking soda, cornstarch, baking powder, and salt.
  4. Add the sifted flour mixture to the butter mixture and mix until just combined.
  5. Stir in the oats and candies by hand.
  6. Use a 2-3 tablespoon scoop (I like to use an ice cream scoop) to scoop out the cookie dough balls. I fit about 6 cookies per sheet.
  7. Bake for 8-10 minutes, or until the edges are just starting to brown.
  8. Let the cookies cool on the sheet for about 5 minutes before transferring them to a wire rack to cool completely.
  9. Enjoy!

Tips for Success

  • You can use most any candy here, but be sure to chop it up into small pieces, roughly the size of an M&M.
  • If the candy happens to have caramel in it, the caramel will probably melt and ooze out. While this is delicious, it is also very hot right out of the oven so be careful!
  • When you remove these from the oven, you may notice the cookies won’t look totally baked. They’ll continue baking a little on the cookie sheet. It is important not to overbake these cookies!
