Chocolate Peanut Butter No Bake Cereal Bars Recipe (Quick to Make)

Cereal bars are a wonderfully versatile dessert to make when you want a quick sweet treat. They don’t require baking. Even better, you probably have all the ingredients you need in your pantry.  So you can feed your sweet tooth in just a few short minutes. Don’t have the usual puffed rice cereal available? Not to worry! You can get creative and use that giant box of Cheerios™ instead. 

In fact, you might decide that you prefer the o-shaped cereal over the puffed rice for the impressively satisfying crunch of these cereal bars.

This recipe follows the same basic principles. But the addition of creamy peanut butter and semi-dark chocolate chips gives this recipe a decadent, sinfully rich flavor that’s hard to beat. 

You will often find Cheerios™ or a similar store brand of o-shaped cereal on sale at your local grocery store. Take advantage of the savings and plan a dessert around any bargain that you might find.  Actually, I often buy them in bulk and dry can them for later use. While they don’t dry-can for indefinite periods, they stay fresh this way for about six months. So I typically have o-shaped cereals on hand. 

Kitchen Tools and Supplies You Need to Make Cereal Bars

Before you make your cereal bars, have everything ready and prepped. Once you begin the process of melting the marshmallows, you need to stir continuously to prevent the sugars from scorching. Also, they start to seize up fast once you remove them from the burner. Preparation is key. 

Also before we get to the method, you can try this in a microwave. I do not own a microwave oven. But I imagine you could melt the butter and marshmallows in a glass bowl on medium heat. If you do try, please share your outcome with us on Facebook. I would love to hear how it works out for you.

All the ingredients you need display on the recipe card below. Besides those pantry items, you need just a few more things:

  • A 9×13 pan, sprayed with non-stick cooking spray. Have this ready before you begin.
  • Non-stick or silicone spoon. I use my favorite kitchen tool–my spurtle, also coating it with non-stick spray.
  • Aluminum foil or plastic wrap for covering and storage.
  • Sharp knife for cutting the squares.
  • A heavy pot for melting the ingredients–too thin a metal pot could scorch the sugar. Adjust down the heat, if needed.

  • Store these in a tightly-capped storage container. These cereal bars keep well for several days. Ideal for sharing with friends and co-workers.
