An ooey gooey cookie bar topped with an assortment of candy bars. The perfect candy bar blondie dessert to make with Halloween candy.

Have a stash of Halloween candy in your kitchen cabinet? I have a ridiculous amount of bags of chocolate candy bars in my kitchen and I thought why not combine two of the very best foods — cookie bars and chocolate candy bars?

It is my idea of perfection…and then the Candy Bar Cookie Bars were born.

The beauty of these leftover Halloween candy cookie bars is that you can use any chocolate candy bar your heart desires. Throw them all on there! The sky is the limit.

After discovering Candy Corn Blondies at Williams-Sonoma, I have even made my own version with my Candy Corn Blondies Recipe for my candy corn lovers out there.

I used Twix, mini M & M’s, Reese’s peanut butter cups, Milky Way bars, Snickers, and Kit Kat…but you can use any of your favorites.

Candy Bar Blondies Instructions:

This is a one bowl cookie bar recipe so you don’t even need a stand mixer or hand mixer. It is so easy!

• In a microwave safe bowl, melt butter in the microwave until melted. I suggest reducing the microwave power so the butter doesn’t splatter. You may also melt the butter in a saucepan.
• Add brown sugar and sugar. Whisk or stir vigorously until smooth about 2-3 minutes. Add egg and vanilla and whisk until smooth.
• Stir in flour, baking soda, and salt.
• Fold in 1 cup of chopped candy bars, reserving most of the chocolate candy bars to place on the top when the blondies are finished baking.
• Spread in a 8 x 8 baking pan. I suggest lining the pan with parchment paper as it makes it easier to remove and cut the candy bar cookie bars.
• Bake just until a light golden brown color. DO NOT OVERBAKE. While the cookie bars are baking, prepare the chocolate candy bars. You may keep some of the candy bars whole and some you can chop or slice into bite-size pieces.
• Place the candy bars all over the top of the baked cookie bars. If you don’t want them to melt, wait 5 minutes before placing on the cookie bars and immediately place in the freezer.

Two tips for easy cutting dessert bars:

How to store Candy Bar Blondie Bars:

Frequently Asked Questions:

You will add 1 cup of chocolate candy bars to the cookie dough and then add more to the top once you remove the bars from the oven. If you don’t want the chocolate candy bars to melt at all, wait a few minutes before adding them and then place in the freezer right away.

For extra chocolately goodness, you can add 1/2 cup of semi-sweet chocolate chips to the cookie dough.
