Long ago when I was a teenager, we had a well-loved cookbook from a natural foods store in Philly. There was a recipe for crispy brown rice bars that we tried and I’ve always remembered it fondly—and love to make this updated version for my family now. This recipe is just three simple ingredients and it comes together in minutes. It’s sweet enough but also has a nice mix of other flavors, too. The texture is that classic chewiness you want in a rice krispie treat, but with a little less sweetness and an easier method. These bars are a great toddler snack or dessert to share. And they work well to make ahead or in the moment, so they’re great as a dessert to share with friends, too.

Homemade Rice Crispy Treats without Marshmallows
This no-bake peanut butter bar recipe relies on brown rice syrup and nut butter to hold them together instead of marshmallows. This means you don’t need to even turn on the stove to make the recipe.
Ingredients You Need
To make this no-bake Peanut Butter Rice Krispie treat recipe, you’ll need to have the following ingredients on hand and ready to go.
Natural unsweetened peanut butter: I usually use Smucker’s brand. Crispy brown rice cereal: Any brand works here. I like to use crispy brown rice cereal in this recipe since I like the flavor and I like that it’s low in added sugar—and has a short ingredient list. You can use traditional Rice Krispies if you prefer. Brown rice syrup: Look for brown rice syrup in the sweetener aisle of your store near the sugar and agave syrup. This gives it the best chewy texture and less intense sweetness, so it’s my preference. If you cannot find it, you can substitute in honey.
Step-by-Step Instructions
Here’s a look at the simple process to make these peanut butter rice krispie bars. Scroll down to the recipe card for specifics.
What kind of peanut butter is best in this recipe?
I prefer to use natural unsweetened creamy peanut butter in this recipe. The Smucker’s shown above is a good option, as is this one from the Whole Foods store brand. Both options make really delicious no-bake peanut butter bars with just the right amount of crispiness.
What can I use in place of brown rice syrup?
So I try as hard as I can to give substitutions, especially when I know an ingredient may be new to many of you like with brown rice syrup. But this recipe really works best with it—it lends the exact texture of a classic Rice Krispie bar without using marshmallows. TIP: I can find it in my small town grocery store in the baking aisle near the sugar. A jar is about $4 and will make about two batches of these bars.
Can you freeze Rice Krispie treats?
Yes, you actually can freeze these and they thaw to a very similar consistency. Be sure to wrap really well, removing as much air as you can from the freezer bag, to create a vacuum effect.
How to Store
These bars are best enjoyed on the day they are made but they can last up to 3 days stored in an airtight container. I prefer to store them in the fridge but they are fine at room temperature too—as long as your room temperature isn’t too warm! (If they get too warm, they may be very sticky.)
Best Tips for Success
Warm the peanut butter and syrup so it’s easy to stir together. Use crispy brown rice cereal or Rice Krispies. Use brown rice syrup for the best results and texture. You can use honey, but you lose the chewy texture from classic Rice Krispie treats. Use unsweetened creamy natural peanut butter. Try sunflower seed butter if needed for an allergy-friendly option. Let set in the fridge for a bit before slicing Add sprinkles if desired. You may also like 3-Ingredient Cereal Bars, Soft-Baked Granola Bars, Healthy Breakfast Bars and Easy Oatmeal Bars.
