This Rice Krispies with M&Ms recipe delivers the perfect balance of crispy cereal clusters and gooey marshmallow magic in every bite. The secret lies in evenly distributing those vibrant M&Ms throughout the mixture, ensuring each treat bursts with color and flavor.
I developed this version after years of testing—no more dry, crumbly treats or overly sticky batches that stick to the pan.
The process is straightforward but requires attention to detail, particularly when melting the butter and marshmallows to achieve that signature creamy texture. Adding peanut butter creates a richer base, while white chocolate chips offer a sweeter alternative to traditional milk chocolate.
This recipe yields about 24 perfect-sized treats, ready in just 15 minutes of active time plus cooling.
What you’ll end up with is a batch of golden-brown, square-cut Rice Krispies treats with pockets of melted marshmallow and crunchy cereal, all studded with colorful M&Ms. The contrast between the crispy edges and soft centers makes these irresistible, whether served at parties, packed in lunchboxes, or enjoyed as an after-dinner indulgence.
The aroma alone will have everyone asking for seconds.
For extra flair, try pressing additional M&Ms into the top before cutting or adding a sprinkle of sea salt for contrast. These treats stay fresh at room temperature for up to 5 days, making them perfect for meal prep or gifting. Let’s get baking!
Ingredients for rice krispies with m&ms
Six cups of cereal, gooey marshmallows, and colorful M&Ms—this is your go-to treat list.
| Ingredient | Amount | Notes |
|---|---|---|
| Butter 🧈 | ½ cup | Unsalted, cut into small cubes |
| Mini Marshmallows 🍫 | 8 oz | Standard size, not jumbo |
| Rice Krispies Cereal 🍞 | 6 cups | Original flavor preferred |
| Peanut Butter 🥜 | ¼ cup | Creamy, no added sugar |
| White Chocolate Chips 🍫 | ½ cup | Optional, for extra sweetness |
| M&Ms 🍬 | 1 ½ cups | Assorted colors, mini or regular |
| Vanilla Extract 🍯 | ½ tsp | Pure, high-quality |
| Sea Salt 🧂 | ¼ tsp | Fine grain, for finishing |
| Coconut Oil 🥥 | 1 tbsp | For greasing pan, optional |
| Powdered Sugar 🍚 | 1 tbsp | For dusting pan |
The butter and marshmallows are the heart of these treats. Use unsalted butter—it’s easier to control the sweetness, and you won’t end up with overly salty treats. I grab the Land O’Lakes unsalted butter from the store because it’s reliable, but any good brand works. Mini marshmallows melt faster and create a smoother texture, but if you’ve got jumbo, just chop them into smaller pieces. The peanut butter adds richness—stick with natural, unsweetened if you can, but the creamy stuff from the peanut butter aisle is fine too. Pro tip: toast your peanut butter in the microwave for 20 seconds to deepen the flavor (trust me on this!).
No white chocolate chips? Milk chocolate chips or even chopped dark chocolate work in a pinch, but white adds that extra sweetness. Running out of M&Ms? Reese’s Pieces or sprinkles bring a similar pop of color and texture. If you’re feeling adventurous, swap the peanut butter for almond butter or sunflower seed butter for a nut-free option. The vanilla extract is non-negotiable—it ties all the flavors together. And if you’re worried about the treats sticking, coconut oil or butter in the pan is your best friend. Just don’t skip the powdered sugar dusting—it keeps everything from sticking like glue.
These treats are best made fresh but stay crispy at room temperature for 5 days if stored in an airtight container. For extra flair, press more M&Ms into the top before cutting or sprinkle with flaky sea salt right after baking—it’s a game-changer. I like to cut them into squares while still warm so they hold their shape, but if you’re in a rush, let them cool completely first. Leftovers? They freeze beautifully for up to 3 months, though they’ll lose a little crunch. Perfect for parties, lunchboxes, or just sneaking a treat when no one’s looking.
Why You'll Love This Recipe
- Three-Ingredient Mix: I swear by this combo—melt the butter with peanut butter first, then fold in marshmallows and cereal. The peanut butter ties everything together so smoothly, you won’t believe it’s just three steps.
- Craving-Worthy Crunch: That first bite? Crispy Rice Krispies, gooey marshmallows melting into peanut butter, and white chocolate chips breaking apart—it’s like dessert hugs your taste buds. Honestly, I’ve made this for adults who “don’t like sweet treats,” and they still ask for seconds.
- Party in a Bowl: Serve it warm in a big glass bowl at birthday parties, or pack it in mason jars for kid lunches. The white chocolate chips stay melty just long enough to make it feel special, even if it’s a Tuesday night.
- Zero-Guilt Leftovers: Make a double batch—it keeps for days in an airtight container (if it lasts that long). The peanut butter keeps the marshmallows from drying out, so it’s just as good cold as it is warm. My secret weapon for lazy mornings.
Step-by-step instructions for Rice Krispies treats with M&ms
Here's how to create the ultimate gooey, colorful treat with perfect texture every time.
Melt Butter and Add Marshmallows
In a large, heavy-bottomed pot, melt the 0.5 cup butter over medium-low heat. I like to use small cubes so it melts evenly without burning. Once fully melted and smooth, reduce heat to low and add the 8 oz mini marshmallows all at once. Stir gently but constantly with a wooden spoon.
Watch closely as the marshmallows begin to soften and clump together. You'll know they're ready when the mixture becomes glossy and pulls away from the sides of the pot in a thick, ribbon-like consistency. This should take about 3-4 minutes—don't walk away! The mixture will thicken quickly, so stay attentive. If it starts to brown, reduce the heat immediately to prevent burning.
Mix in Cereal and Sweeteners
Immediately remove the pot from heat and add the 6 cups Rice Krispies Cereal, the 0.25 cup peanut butter, and the 0.5 cup white chocolate chips. Stir vigorously with a wooden spoon or spatula to distribute everything evenly. You'll notice the peanut butter will thicken the mixture slightly, which is perfect for binding everything together.
Next, fold in the 1.5 cups M&Ms and the 0.5 tsp vanilla extract. The M&Ms will be scattered throughout, creating those beautiful pops of color. Here's the thing—don't be tempted to rush this step. Keep mixing until you see the peanut butter fully incorporated and the M&Ms evenly distributed. The mixture should look thick and clumpy, like wet sand, but still workable.
Press into Pan for Perfect Clusters
Lightly grease a 9x13-inch baking pan with 1 tbsp coconut oil and dust it evenly with 1 tbsp powdered sugar. This creates a non-stick surface that prevents the treats from sticking. Using a greased spatula, press the marshmallow mixture firmly and evenly into the pan. I like to use a bit of elbow grease here—press down until the mixture is compacted and smooth.
Here's where it gets fun—sprinkle the 0.25 tsp sea salt lightly over the top. This adds a subtle contrast to the sweetness and enhances the overall flavor. Once the pan is evenly covered, let the mixture sit for 5 minutes to firm up slightly. This resting period makes it easier to cut into perfect squares later.
Chill and Cut for Crunchy Perfection
Transfer the pan to the refrigerator and chill for at least 1 hour, or until completely firm. The treats should hold their shape when you lift a corner. If you're in a hurry, you can speed this up by placing the pan in the freezer for 30 minutes, but I prefer the refrigerator for even cooling.
Once chilled, remove the pan from the refrigerator and let it sit at room temperature for 5 minutes to make cutting easier. Using a sharp knife, cut the treats into 24 squares (about 2 inches each). For cleaner cuts, dip the knife in hot water and wipe it dry between cuts. The result should be crispy edges with a gooey, marshmallow center—absolute perfection!
Pro Tips For Making Rice Krispies With M&Ms
- Melt Butter Slow: I learned this the hard way—dumping butter straight into a hot pan and getting a greasy mess. Instead, melt it in a microwave-safe bowl in 30-second bursts, stirring between each, until it’s just liquid and smooth. This keeps your peanut butter from seizing up when you mix it in later.
- Toast Marshmallows Separately: If you’re adding white chocolate chips, toast the marshmallows alone first in a dry skillet over medium heat. Stir constantly until they’re golden and puffy—this prevents them from turning into a sticky, uneven glob when mixed with the peanut butter and cereal. (Yes, it’s extra work, but the texture is worth it.)
- Skip the Overmixing: Once you fold in the Rice Krispies, stop stirring the second everything clumps together. Overmixing makes the peanut butter turn greasy and the whole thing dense. A few uneven spots? Doesn’t matter—it’ll still taste like a childhood memory.
- Chill Before Serving: Let the mixture sit for 10 minutes after it’s done, then press it into a pan and refrigerate for at least 30 minutes. This keeps the white chocolate from melting into a sad, soupy mess when you cut it. (Trust me, you’ll regret skipping this if you’re serving it to kids.)

Frequently asked questions
Can I make these treats without peanut butter?
The peanut butter adds richness, but you can omit it entirely or substitute with 0.25 cup almond butter, sunflower seed butter, or even extra marshmallows for a sweeter version. Just reduce the cereal slightly (5 cups) to maintain the right texture. The treats will still hold together beautifully.
Why did my Rice Krispies treats turn out sticky instead of crispy?
Sticky treats usually happen when the butter-marshmallow mixture doesn't cool enough before adding cereal, or if the pan wasn't properly greased. Let the mixture sit for 5 minutes after pressing into the pan to firm up slightly. Also, chill for the full 1 hour in the fridge—rushing this step is the #1 cause of stickiness. For extra insurance, dust the pan with powdered sugar before pressing.
How can I make these treats gluten-free?
Use a gluten-free Rice Krispies cereal (like Rice Chex) and check that your marshmallows and chocolate chips are certified gluten-free. The peanut butter and M&Ms are typically safe, but always verify labels. The texture will be slightly different but still delicious. For extra binding, consider adding 1 tbsp cornstarch to the cereal mixture.
Can I use regular M&Ms instead of mini ones?
Yes, but you'll need to adjust the quantity. Use about 1 cup regular M&Ms instead of 1.5 cups mini to maintain the same visual impact. Regular M&Ms will create larger color clusters, which works great for a bold look. Just be sure to press them evenly into the top before cutting for the best presentation.
What's the best way to store these treats for maximum freshness?
Store in an airtight container at room temperature for up to 5 days. For longer storage, freeze in freezer bags for 3 months. To maintain crispiness, let treats sit at room temperature for 10 minutes before eating after refrigeration. Avoid storing in humid environments—they'll soften faster.
