Halloween is coming up quick and I’ve been hard at work creating healthier holiday snacks to share with you guys!

Rice Krispies treats were a favorite of mine growing up, so this year I decided to try a more nutritious (and flavorful) take on this popular crunchy dessert using the tasty new certified organic Love Crunch Cereal from Nature’s Path.

These bars require three simple ingredients: cereal, peanut butter, and a small amount of maple syrup.

You can use any cereal you like, but I chose to incorporate one that is not only scrumptious — hello, dark chocolate chunks — but also nutritious.

This whole grain cereal has 3 grams of fiber and 5 grams of protein per serving, making it a much healthier option compared to Rice Krispies, which completely lacks belly-filling, cancer-fighting fiber and only has one gram of protein per serving.

My bars also incorporate a delicious source of monounsaturated fat thanks to the creamy peanut butter, and they derive sweetness from a hint of maple syrup, skipping the butter and marshmallows found in your classic cereal bar recipe.

This recipe couldn’t be simpler. The no-bake technique is great for kids, making it a no-brainer for an easy, tasty Halloween treat.

It’s also a great dessert for cereal-loving adults like my husband who told me, “this is the best thing you’ve ever made.”

To that, I replied, “Well, it’s pretty much the easiest thing I’ve ever made and all the credit goes to the delicious cereal, but thank you for the compliment, I guess?”
