When I was a teenager I loved making up recipes. I didn’t know what I was doing, of course. Maybe that’s why I liked it. The process and the outcomes were always a mystery!

I loved working with chocolate and peanut butter. Who doesn’t! This recipe is one of the darlings that I experimented with basing it off of another recipe I had seen. The idea of making rice krispie treats with peanut butter, instead of marshmallows was amazing to me!

I didn’t like the combination of chocolate and marshmallows at the time (talk about finicky!), so I knew this peanut butter rice krispie bars recipe was going to be a real gem!

Also, once I saw a bumper sticker that read: I do whatever my rice krispies tell me. I’m still laughing about that!

Ingredient Spotlight

What are Rice Krispies?

This little cereal treat has been around since 1927 and was invented by Malitta Jensen and Mildred Day. It’s basically a rice paste that is dried and then baked. When milk is added to them, they “snap, crackle, and pop” as they rehydrate. They are also added to other treats, such as peanut butter balls, to add crispy crunch bites. You can use the brand or store-brand cereal for this recipe. Just be sure to get Rice Krispies rather than puffed rice.

How to Make Peanut Butter Rice Crispy Treats

If you’re curious about how to make some old-fashioned peanut butter rice krispie treats, I’m here to show you how. In fact, let’s have some fun too! Let’s begin.

  1. Make the peanut butter sauce by heating it in the microwave and stirring.
  2. Pour the peanut butter sauce over the cereal and stir until coated.
  3. Spread the peanut butter cereal into the prepared pan.
  4. Heat chocolate chips and vegan butter in a microwave-safe bowl and then stir in milk.
  5. Spread the chocolate fudge topping over the peanut butter layer.
  6. Cover and refrigerate for at least 30 minutes to an hour.

Here are more detailed step-by-step instructions:

Step One: Prepare the Pan

Begin by preparing an 8″ square cake pan by using vegan butter or coconut oil to grease both the bottom and sides.

Step Two: Prepare the Peanut Butter Sauce

A hand holds a measuring cup full of syrup and is pouring it over a glass bowl full of peanut butter.

Make the sweet peanut butter sauce by combining creamy peanut butter and agave nectar in a microwave-safe bowl. Heat in 30-second increments, followed by stirring, until the peanut butter is “melted” (or runny) and able to be stirred in with the agave nectar. Add vanilla and stir to combine.

A note on syrup: I used agave nectar, but you can substitute your favorite syrup like maple syrup, corn syrup, or even a date syrup (although it will be a bit darker).

Step Three: Make the Bars

Peanut butter sauce is being poured over a bowl of rice krispies cereal.

Pour in the rice crispy cereal into a large bowl. Add the peanut butter sauce while it’s still warm (so it will be runny) and stir until the rice crispies are evenly coated.

Pour the coated rice crispy mixture into the prepared pan and spread it around all the edges of the pan. Use your fingers or the back of a spoon or spatula to press the peanut butter rice crispy mixture into the bottom of the pan.

Marly’s Tips

You can make chocolate peanut butter rice krispie balls by using a cookie scoop to portion the batter and then rolling them into balls. Either dip them in melted chocolate or serve them as is. They’re delicious either way!

Step Four: Make the Chocolate Fudge Topping

Cubes of vegan butter are sitting on top of chocolate chips in a glass bowl.

Next. combine the chocolate chips and vegan butter (or coconut oil) in a microwave safe bowl. I cut the butter into cubes to ensure even melting. Heat for about 30 seconds. Then remove the bowl and stir to ensure the chocolate chips are coated.

A hand holds a measuring spoon of plant-based milk and is pouring it over melted chocolate.

Return the bowl to the microwave and heat for another 30 seconds. Use oven mitts to remove the bowl and cover it with a plate or lid. Allow it to sit for about a minute to help the chocolate chips melt. Then stir.

Add the milk, one tablespoon at a time, stirring in between until you get the desired spreadable consistency.

I love using vegan evaporated milk because it’s rich and creamy, but any old plant-based milk will do!

Step Five: Refrigerate and Serve

Cover the pan and place it in the fridge where you can stand nearby for an hour, waiting for it to set. Trust me, it’s worth the wait.

Storage Tips

Simply cut them into individual slices and transfer them to a airtight container. They can be kept at room temperature for up to 3 days or in the fridge for up to 10 days. If you have to stack them on top of one another, place a sheet of waxed paper between the layers.

Notes

A note on salt. You can add up to 1/2 teaspoon of salt to the peanut butter sauce, however, I find most peanut butter has salt added to it, so I don’t find it necessary.

    Hi there, these look absolutely amazing and I love your photos. I am trying to avoid peanut butter, do you think almond butter or cashew butter would work well in these? I know cashew butter works perfectly as a substitute in PB cookies, even better than Almond butter so that might be better. Looking forward to trying these, thanks for the recipe!

      Hi Dana. I’ve never tried anything but peanut butter with these, but I can imagine cashew butter and it sounds fantastic. What about hazelnut butter? I mean, how can you go wrong with hazelnut and chocolate? OK. Well, anything with chocolate really works here so let me know if you try it and how it goes!

    Made these the other night and oh my dear lord. Did a double batch, here were my swaps:
    -used brown rice syrup instead of corn syrup
    -didn’t use the cream cheese layer
    -only did a single batch of the chocolate, but did dark chocolate and salted it

    Everyone who has been freaking out at how amazing they are. If I had put in the cream cheese layer, our heads might have exploded! Thank you for the recipe!

    In the first part of the directions, in step 4, it says to coat the crisps in the chocolate peanut butter coating. Is there a missing ingredient to the first section of mixing? I don’t see that there’s chocolate in that part of the recipe. I made it as stated so we’ll see how it turns out tomorrow!:)

      Hi Della! Thanks for pointing that out. I realized based on your comment that I forgot to include the cocoa in the first part of the recipe. It’s optional and would taste fine either way. I just happened to like the idea of a chocolate peanut buttery spread. I hope you enjoyed the bars!

    Oh my lord. I know I’m a little late to the party on this one, but I need this in my life, like, now. They remind me of something my grandma used to make (but far from vegan). My step-daughter was walking behind me while I was looking at this, and she stopped in her tracks when she saw the pictures. Then she asked when we’re having them, lol. Can’t wait to try them! Thank you!

      Hi Kristy – I can’t wait for you to try them and then let me know how it goes! I love things that remind me of meals with my family. That reminds me, I think there might be a big family meal coming this weekend! Yeah!

    These look fantastic! And I love the chickpea-rather-than-cream cheese idea. Thanks!

      I agree. Now I’m going to have to make them again, but this time with the chickpea variation. Yumm!
