Halloween Candy Cookie Bars

Seriously – How fun are these cookie bars?

Halloween is tomorrow and we all are going to be up to our eyeballs (get it?) in candy amiright? Earlier this month, Pat and I made a trip to Costco and bought 4 packages of full-size candy bars to hand out. Only except we dipped into them that same weekend and all the Reese’s peanut butter cups are now gone and the KitKat bars are almost gone as well. #nowillpower

With that said, I did pick up some extra bags of candy. After opening the bag, I wanted to eat them all. <—see no will power. None. I then thought of ways I could eat allthecandy. I know right? The smell of halloween candy is the BEST. This is what inspired me to make these fun Halloween Candy Cookie Bars.

I used our favorite candy bars. Reese’s pb cups, KitKat bars, Hershey and I even made a special trip to pick up candy eyeballs. They add a little somethin-somethin don’t you think?

First, line a 9 x 13 x 2 baking pan with parchment paper and lightly spray with nonstick spray. Then, in a medium bowl, combine 2-1/4 cups unbleached all-purpose flour, 1 teaspoon baking soda and 3/4 teaspoon kosher salt. Stir and set off to the side.

Either lightly spray your fingers with nonstick spray or use a sheet of wax paper or parchment to press the dough evenly in the pan.

FYI the wax paper/parchment route is the cleanest.

Slip the pan onto the middle rack of your preheated 350° oven and bake for 18 to 20 minutes. Rotate the pan halfway through.

Meanwhile unwrap, break up and or chop the chocolate candies. I used peanut butter cups, Hershey’s bars, KitKat bars, more M&M’s, Reese’s Pieces and some candy eyes. But you could also do snickers, butterfingers, take 5’s … I now have another variation to consider.

Once the cookie bars have come out of the oven, immediately press the candies into the top of the bars. Doing this while the top of the cookie bars are soft is the only way you will get them to stick. Promise.

Why not bake the bars WITH the candy bars on top? In my opinion, the oven does weird things to the chocolate. I don’t think candy bars should be baked either – unless they are IN the dough.
