Why You’ll Love This Recipe

I love this recipe because it’s no-bake, quick to throw together, and full of nostalgic flavor. The peanut butter adds a rich, salty-sweet layer, while the M&M’s and chocolate chips bring color and extra indulgence. These treats are soft and gooey with just the right amount of crunch—and they stay that way for days. Plus, they’re super customizable.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• Rice Krispies cereal

• Mini marshmallows

• Creamy peanut butter

• Unsalted butter

• Vanilla extract

• M&M’s

• Mini chocolate chips

Directions

1. I line a 9×13-inch baking dish with parchment paper or lightly grease it for easy removal.

2. In a large pot, I melt the butter and peanut butter together over low heat, stirring constantly until smooth.

3. I add the mini marshmallows and stir until they’re fully melted and blended into the mixture.

4. I remove the pot from heat and stir in the vanilla, followed by the Rice Krispies cereal. I mix until everything is evenly coated.

5. Once the mixture is slightly cooled (but still warm), I gently fold in most of the M&M’s and mini chocolate chips, saving some for the top.

6. I press the mixture into the prepared pan, using a spatula or lightly greased hands to smooth it out evenly.

7. I sprinkle the remaining M&M’s and chocolate chips on top and press them in lightly.

8. I let the treats cool at room temperature for about 1 hour before cutting into squares.

Servings and timing

This recipe makes about 20 squares. It takes 10 minutes to prepare and about 1 hour to set, so I can have them ready to serve in just over an hour.

Variations

Sometimes I use crunchy peanut butter for more texture or swap the M&M’s for peanut butter chips or Reese’s Pieces. For a holiday version, I use seasonal-colored candies. I’ve also made them with Cocoa Krispies for a double chocolate hit.

Storage/Reheating

I store these treats in an airtight container at room temperature for up to 4 days. I keep them in a cool place so the chocolate doesn’t melt. I don’t refrigerate them, as that can make them too hard. No reheating is needed—just enjoy them as they are.

FAQs

Can I use natural peanut butter?

I usually stick with creamy, no-stir peanut butter for the best texture. Natural peanut butter can be too oily or dry and may cause the treats to separate.

How do I keep the treats soft?

I don’t overcook the marshmallow mixture, and I mix gently to avoid compacting the cereal. Letting them cool uncovered also helps keep them chewy.

Can I use regular-sized chocolate chips?

Yes, I’ve used them before. I just make sure to add them once the mixture cools slightly so they don’t melt too much.

Can I make these ahead of time?

Definitely. I often make them a day ahead and store them covered at room temperature until serving.

What’s the best way to cut them cleanly?

I let them cool completely, then use a sharp knife coated with a little cooking spray or butter to slice clean, even squares.

Conclusion

Peanut butter Rice Krispie treats with M&M’s and chocolate chips are a fun, sweet snack that’s easy to love and even easier to make. With their soft, chewy texture and bursts of candy and chocolate in every bite, they’re perfect for parties, lunchboxes, or satisfying a sudden craving. I always keep this recipe on hand for a quick, no-fuss treat everyone enjoys.
