Every year once Halloween is over, that bowl of leftover candy sits in the cabinet. Usually it doesn’t last long because I have no will power and will eat it for breakfast, lunch and dinner and then I’ll have Rick take some to work to get it out of the house. These Leftover Halloween Candy Cookie Bars are the perfect and most delicious way to use up that candy!
Leftover Halloween Candy Cookie Bars
Ingredients:
- 2 1/4 cups of all purpose flour
- 1 tsp baking soda
- 3/4 tsp salt
- 3/4 cup unsalted butter at room temp
- 3/4 cup brown sugar
- 3/4 granulated sugar
- 2 eggs
- 1/2 tsp vanilla extract
- 1 cup chocolate chips
- leftover Halloween candy (I find that the chocolate based works best – no gummy or sour candies)
- I added these leftover googly eye sprinkles we had
Directions:
- Preheat your oven to 350 degrees F.
- Line a baking tray with parchment paper or spray really well with nonstick baking spray.
- In a medium bowl, mix together flour, baking soda and salt.
- In a separate bowl (I used my Kitchen Aid), mix together butter, brown sugar and granulated sugar until creamed together.
- Add in the eggs and vanilla, mixing well.
- Add in the flour mixture (dry ingredients) into the wet ingredients and stir until combined.
- Sprinkle in the chocolate chips. (If you have M&Ms you can use those too!)
- Spread the cookie dough on the prepared baking tray, pressing down until firm.
- Bake until golden brown (about 20 minutes)
- While the cookie dough bakes, unwrap your chocolate candy and break into chunks.
- When the cookie dough is done baking, remove from the oven. Press the chocolate candy pieces into the top of the cookie dough while still warm. We had leftover googly eye sprinkles so I sprinkled those on too.
- Allow to cool completely, then cut and serve.
