This past weekend, I experimented with a few new rice crispy treat tastes.  Of course, I had to try a peanut butter and chocolate variation. I love the combination of peanut butter and chocolate, and they worked perfectly with the crispy rice cereal bars. 

These Peanut Butter Cup Rice Krispie Treats are easy to make and so tasty! They have all of the flavor of a peanut butter cup in everyone’s favorite easy treat; a rice krispie square! You can have dessert or an afternoon snack ready in a matter of moments with this recipe!

Rice Krispie treats are one of my secret weapons as a busy mom. I love that you can make them basic or add frills like peanut butter, candy or anything you desire! Rice Krispie treats aren’t messy to make or eat, making them ideal for adding to lunchboxes or serving as an after-school snack.

If you are a serious peanut butter fan, feel free to add a few extra spoonfuls to the mix. If you can’t get enough chocolate; melt a little extra and add it in. This recipe is bound to become a family favorite, so make the adjustments you like and watch your family gobble them up!

  • 3 T Butter

Delicious! My favorite version is to use Fruity Pebbles and fruit flavored marshmallows. It is so delicious and makes it impossible to go back to traditional Rice Krispy treats. Thanks for sharing your yummy recipe and for linking up with me On the Edge!
