Halloween Monster Cookie Bars

Yield: 9 blondies

Prep time: 10 minutes

Cook time: 20-25 minutes

Ingredients

• ½ cup butter, room temperature

• 1 cup brown sugar

• 1 egg, room temperature

• 2 teaspoons vanilla extract

• 1 cup all-purpose flour

• 1 cup old-fashioned oats

• ½ teaspoon baking powder

• ½ teaspoon baking soda

• 1 teaspoon salt

• ½ cup chocolate chips

• 1 cup roughly chopped Halloween candy bars (I used Kit Kat, Snickers, Smarties, and Mars)

Directions

1. Preheat to 350°F and grease and line an 8x8-inch pan with parchment paper.

2. In a large bowl, cream the butter and brown sugar. Add the egg and mix until light and fluffy. Then, add your vanilla extract and combine into the mixture.

3. Add the flour, oats, baking soda, baking powder, and salt to the bowl and fold into the wet ingredients until just combined. Lastly, add the chocolate chips and chopped candy bars to the mixture and fold in, saving ¼ cup for topping.

4. Spread the dough evenly in the lined pan and lightly press the remaining chopped candy bars into the dough. Bake for 20-25 minutes, or until the edges are golden brown and the middle is still a bit gooey.

5. Remove from the oven and set the pan on a baking rack for 30 minutes to cool. Carefully pull the blondies out by grabbing the parchment paper underneath and place on a cutting board. Cut into 9 equal squares and enjoy!
