Candy Oreo Monster Blondies are the perfect way to use up Halloween candy

Is your pantry overflowing with half-opened bags of candy?

If you’re like me and trying to find ways to reduce that leftover candy stash, tossing them into some baked goodies is an easy and delicious way to help get rid of some.

I made these Candy Oreo Monster Cookie Bars a few weeks ago and we couldn’t resist throwing in whatever all the half-opened packages of treats we could find.

They start off with my favorite soft blondie base from America’s Test Kitchen. They are my absolute favorite and no-fail recipe that I’ve been using for years. Then you just toss in whatever candy you have lying around.

Various Add-ins

Next are the fun add-ins. You can totally use whatever add-ins you like. For these Candy Oreo Monster Blondie Bars, we used:

Some bright and colorful M&M’s
Twix
Chopped up Oreo cookies.

These Candy Oreo Monster Blondies bake perfectly in about 30 minutes and you’ll have soft, chewy bars that are thick and full of texture with a slightly gooey center.

Best of all, they are a great way to use up any leftover candy taking over your pantry and everyone will love this fun and delicious treat!
