Halloween No Bake Bars! Loaded with chocolate, peanut butter, and m&m candies! #halloween #candy #peanutbutter

Everyone knows that the best part about Halloween is Reese’s Pumpkins, right? 

I mean…they’re the best shape. I’ll fight you on that. 

Of course, my husband makes fun of me when I buy candy for myself…apparently he thinks that adults don’t eat candy bars? Pfft. He’s wrong, obviously.

But, either way, I thought I’d get my chocolate peanut butter fix via a sweet homemade treat this time around and these no bake peanut butter bars were born.

They start with peanut butter, get topped with chocolate, and are finished off with a sprinkle of crushed Halloween m&m’s. Love these bars because they’re totally easy but super festive and fun!

Feel free to skip the m&m candies and use whatever festive goodies you can find…sprinkles work well!

How to make these no-bake peanut butter bars: 

ingredients for no bake peanut butter bars

Add graham cracker crumbs, powdered sugar, peanut butter, and melted butter to a mixing bowl and stir until well combined.

You don’t even need to get your mixer dirty for this one!

Once the mixture is combined, spread it into a greased 9×9 baking dish. 

Melt some chocolate chips in the microwave and then pour the chocolate over the peanut butter layer. Smooth it all out.

Chop or crush some m&m’s. When they’re chopped up, the candy coating flakes off a bit giving you this colorful candy dust that makes the bars even prettier. 

Sprinkle the candy over the top and pop the dish in the refrigerator for at least 2 hours before cutting and serving.

These should be stored in the refrigerator.
