Ooey, gooey and delicious, these one bowl Candy Bar Blondies are the perfect sweet treat!

What’s your favorite Halloween candy?

I have several: Midnight Milky Ways, Reese’s Peanut Butter Cups, Kit Kats and Butterfingers.  But even with that long list,  I’m not a huge candy eater. A piece here or there is great, but after that, I’m kind of over it. My kids are the same way (I’m lucky, right?). They go crazy for the first day or two, and then they kind of forget about it….and then it sits here for months. In fact, I just found Easter basket remnants last week! So either I toss it all, send it to work with Kevin or get creative with my food. Naturally, I chose to tinker in the kitchen, and here you have these super simple One Bowl Candy Bar Blondies.

These blondies are the perfect blank canvas just waiting for your favorite candy bar. And believe me, they work with all different kinds. I made them several times when I was recipe testing, once with Butterfingers, another time with Twix and finally with Kit Kats. So generous of me, right? I’m happy to report that they work with all of them!  Layers of buttery goodness with a candy bar morsel in every bite. I don’t think you can go wrong with these bars! And with a short ingredient list (I bet you have everything in your pantry), and only using one bowl, they are a guaranteed winner. Halloween candy dilemma solved.

These One Bowl Candy Bar Blondies are the perfect dessert to make with leftover candy!

    Such a great idea to use up Halloween candy. I’ll have to make sure I buy more of my personal favorites so I can use them up in this recipe.

    We still have Easter candy too!!! But mostly because I’m a Scrooge and am super stingy with handing it out. If my daughter had her way she would eat chocolate morning noon and night. I LOVE the look of these bars! So perfect!
