Not sure what to do with all your leftover halloween candy? Load up these chewy and gooey cookie bars!


  • 1/2 cup unsalted butter, melted
  • 1/2 cup creamy peanut butter
  • 1 cup light or dark brown sugar, packed
  • 1/2 cup granulated sugar
  • 1 tbsp molasses
  • 2 tsp vanilla extract
  • 2 large eggs
  • 2 cups all-purpose flour
  • 1 cup old fashioned rolled oats
  • 3/4 tsp salt
  • 1/2 tsp baking soda
  • 1/2 cup dark chocolate chips (optional)
  • Chocolate-based leftover Halloween candy


  1. Before you start, make sure your candy is cold. Place it in the fridge for about an hour before baking.
  2. Preheat the oven to 350F. Grease and line a 9×13 baking pan with parchment paper.
  3. Combine the flour, oats, salt, and baking soda in a small bowl. Set aside.
  4. Cream together the melted butter , peanut butter, and sugars until smooth. This can be done with a hand mixer, stand mixer with the paddle attachment, or a whisk. 
  5. Mix in the molasses, vanilla, and eggs. Scrape down the bowl and mix again.
  6. Toss in the dry ingredients and mix until combined. 
  7. At this point, you can fold in the chocolate chips (optional) or instead/also mix in chopped up Halloween candy. I mixed in a combo of chocolate chips and M&M’s.
  8. Press the dough into the pan and press in your chilled Halloween candy. Add as much as you like, but be careful not to crowd the bars too much.
  9. Bake for 25-28 minutes. The edges should be slightly puffed up and golden brown and the center should be dull and golden.
  10. Let the bars cool completely before digging in. The edges are nice and chewy/soft while the center is extra gooey. Store in the refrigerator.
