If you need a super quick and easy recipe that everyone will love, these marshmallow treats are it! They’re just as soft and gooey as a good rice krispie treat, but with peanut butter and chocolate melted into the mix. Once melted, mixed, pressed, and chilled in a pan, these bars slice into thick and rich marshmallow treats with even more melted peanut butter on top. I’ve also included a simple cereal swap to make these gluten free if needed!

Chocolate peanut butter marshmallow treats ingredients

This recipe only requires 6 basic ingredients that you either have on hand OR can easily pick up at any local grocery store! Here’s what you’ll need:

• Butter
• Chocolate Chips
• Peanut Butter
• Marshmallows
• Rice Cereal
• Vanilla Extract

These ingredients can also be easily subbed in to adjust to most food sensitivities!

If you need these to be gluten free, swap the rice cereal with Rice Chex or certified gluten free puffed rice cereal.

To make these dairy free and vegan, swap the butter with plant-based butter and sub in dairy free chocolate chips. I like Trader Joe’s semisweet chocolate chips or Enjoy Life, and Miyokos or Earth Balance for the butter.

If nuts are off the table, simply sub in sunflower seed butter. My favorite is creamy SunButter.

No matter how you mix it, these bars turn out delicious either way!

Tips for making the BEST marshmallow treats

To get the most out of this simple recipe, follow these super simple tips:

1. Butter – For the biggest flavor payoff, use quality butter such as cultured or European style butter. It’s much more flavorful than standard butter and will lend a rich chocolate marshmallow treat.
2. Creamy Peanut Butter – Stick with the standard creamy peanut butter for this recipe like Jif or Skippy. It lends the best consistency.
3. Chocolate – This is another ingredient to splurge on as good chocolate makes ALL the difference. I love Guittard dark chocolate chips in the red bag but don’t be fooled by the name as they lean more towards semisweet in flavor.
4. Melting – I usually like to partially melt down the marshmallows when I make marshmallow treats, but not this recipe! Make sure everything is completely melted and smooth before tossing in the cereal.
5. Pressing – Really pack the mixture down into the baking pan. The more tightly packed the bars, the better the consistency. They’ll turn out super dense and gooey but with a satisfying crunch from the cereal.
6. Sea Salt – This is completely optional, but I top almost all my desserts with flaky sea salt! Sprinkle a few pinches on top after drizzling with more peanut butter.

How to slice and serve peanut butter chocolate marshmallow treats

After the mixture is pressed into the pan, chill the bars in the refrigerator just until set.

To test for doneness, lightly touch the surface. If it appears dull and feels firm, they’re ready. If they’re shiny and a bit tacky, allow them to chill a bit longer.

Then, when lifting the bars out of the pan, there shouldn’t be any sort of give in the center. If the bars bend in the middle when lifted, they aren’t ready.

When slicing, use a large knife and make quick and swift cuts. Try not to drag the knife long the bars as this can lead to messy slices.

Now they’re ready to eat! Although I personally like to let mine rest at room temperature for about 20 minutes as they’ll turn extra soft and gooey.

How to store marshmallow bars

Keep these bars in an airtight container at room temperature where they’ll keep for about 4 days! I don’t recommend storing in the refrigerator as they can turn stale faster this way.
