How to Make Peanut Butter Rice Krispie Treats with M&M’s and Chocolate Chips
Step 1: Melt Butter and Peanut Butter
Grab your largest saucepan and set it over medium-low heat. Add the butter and peanut butter, then stir them together with a wooden spoon or heat-resistant spatula. As they melt, the mixture will turn glossy and smooth. Be patient and keep the heat gentle to prevent scorching the peanut butter—this is the foundation of your bars’ flavor and texture!
Step 2: Add Marshmallows
Toss in the whole bag of mini marshmallows and stir continuously as they start to soften, puff up, and finally melt into the peanut butter mixture. Keep mixing until everything is perfectly combined and lusciously gooey. At this stage, your kitchen will start to smell amazing!
Step 3: Stir in Vanilla Extract
Once you’ve reached full melted marshmallow glory, remove the pot from the heat. Quickly stir in the vanilla extract—it’ll sizzle a bit, but that’s normal. Vanilla brings a subtle, homey sweetness that balances the bold peanut butter and chocolate flavors.
Step 4: Fold in Rice Krispies Cereal
Now add the Rice Krispies, pouring them in gradually for easier mixing. Gently fold the cereal into the warm marshmallow mixture until every puffed grain is coated. Work somewhat quickly so the mix stays pliable. This step gives your Peanut Butter Rice Krispie Treats with M&M’s and Chocolate Chips their signature chew!
Step 5: Add Most of the M&M’s and Chocolate Chips
Wait just a minute or two for the mixture to cool slightly—then it’s time for the best part! Fold in most of the mini M&M’s and chocolate chips, saving a small handful of each for later. Adding them while it’s still a little warm ensures some will melt dreamily, while others stay intact for bursts of chocolate and color throughout.
Step 6: Press into Pan and Top
Transfer the mixture into a greased 9×13-inch baking dish (or line the pan with parchment for effortless removal). Use a spatula or wax paper to press the mixture firmly and evenly into the corners. While it’s still a touch warm, scatter the reserved M&M’s and chocolate chips on top and gently press them in—this makes the bars extra festive and guarantees visible candy in every slice.
Step 7: Cool and Slice
Let the treats cool completely at room temperature for about an hour. If you’re in a hurry or want nice, neat edges, you can chill them in the fridge for 20 to 30 minutes before slicing. Once they’re set, lift them out (if using parchment) and cut into 16 perfect squares. Prepare yourself for a wave of happiness as you admire the colorful, gooey mosaic you’ve created!
How to Serve Peanut Butter Rice Krispie Treats with M&M’s and Chocolate Chips

Garnishes
For an extra ‘wow’ factor, sprinkle a pinch of flaky sea salt on top just before serving—the savory contrast is absolutely dreamy with the sweet chocolate and peanut butter. If you’re feeling whimsical, try drizzling with a bit of melted white chocolate or even more peanut butter for a gourmet touch.
Side Dishes
Pair your Peanut Butter Rice Krispie Treats with M&M’s and Chocolate Chips with ice-cold milk, classic hot cocoa, or a scoop of vanilla ice cream for ultimate dessert decadence. Their rich, chewy texture plays perfectly with anything creamy or frosty on the side!
Creative Ways to Present
For a playful twist, pop the bars onto lollipop sticks to make Rice Krispie Treat pops—kids (and adults) can’t resist them at bake sales or parties! Stack individual squares in mason jars tied with ribbon for gifting, or layer them on a colorful platter for potlucks and picnics. However you present them, you’ll instantly brighten the table.
Make Ahead and Storage
Storing Leftovers
These treats are just as delicious the next day! Store leftover squares in an airtight container at room temperature for up to 4 days. If your kitchen is especially warm, a quick stint in the fridge will help keep the chocolate from getting melty, but let them come to room temp for the best texture.
Freezing
Peanut Butter Rice Krispie Treats with M&M’s and Chocolate Chips freeze beautifully. Wrap each square individually in plastic wrap, then tuck them into a freezer-safe bag or container. They’ll stay fresh for up to 2 months—just allow a few hours at room temperature to thaw before enjoying.
Reheating
If you love that just-made softness, pop a square in the microwave for 5–10 seconds. This will restore some of that gooey marshmallow goodness and wake up the chocolate chips—just keep an eye out if you’re dealing with a lot of M&M’s, as the candy shell can get hot quickly!
FAQs
Can I use natural peanut butter instead of regular?
You can, but keep in mind that natural peanut butter is oilier and may lead to slightly softer treats. If you try it, stir the peanut butter well and consider adding a touch more cereal to balance the texture.
What’s the best way to keep the M&M’s and chocolate chips from melting?
Let the cereal-marshmallow mixture cool for a couple of minutes before folding in the candies. This keeps most of the M&M’s and chocolate chips whole, so you get those colorful bursts in every bite and a picture-perfect look.
Can I use regular-sized M&M’s and chocolate chips?
Mini versions are best, as they distribute more evenly, but you can absolutely use regular ones if that’s what you have on hand. The treats will just have bigger pockets of chocolatey goodness!
How can I make these gluten-free?
Choose a certified gluten-free crispy rice cereal and check your marshmallows and peanut butter for hidden gluten sources. The rest of the ingredients are naturally gluten-free, making these an easy choice for anyone with sensitivities.
Should these be stored in the refrigerator or at room temperature?
Room temperature is usually perfect for storing Peanut Butter Rice Krispie Treats with M&M’s and Chocolate Chips, especially if you eat them within a few days. In hot weather, the fridge can help keep the candies and chocolate stable, but always let them warm up a bit before serving for the best flavor and chew.
Final Thoughts
There’s nothing quite like sharing Peanut Butter Rice Krispie Treats with M&M’s and Chocolate Chips with the people you love—it’s the kind of feel-good treat that’s impossible to outgrow! Whip up a batch the next time you want to spread some sweetness, and watch how quickly these cheerful squares disappear. Happy snacking!
