Ingredients for rice krispie bar recipe with marshmallow creme
Crispy rice clusters, gooey marshmallow creme, and a golden crust—these 12 ingredients make magic happen.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍚 | 6 cups | Original or lightly buttered variety |
| Large Marshmallows 🍬 | 2 cups | Mini marshmallows for smaller clusters |
| Marshmallow Creme 🍯 | 1 cup | Vanilla or white chocolate flavor |
| Unsalted Butter 🧈 | ½ cup | Melted for binding |
| Granulated Sugar 🍚 | ½ cup | For golden crust |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality extract |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Powdered Sugar 🍚 | ¼ cup | For dusting (optional) |
| Dark Chocolate Chips 🍫 | ½ cup | For drizzling (optional) |
| Peanut Butter 🥜 | ¼ cup | Creamy, for variations |
| White Chocolate Chips 🍫 | ½ cup | For white chocolate swaps |
| Crushed Nuts 🌰 | ½ cup | Optional texture boost |
The marshmallow creme is non-negotiable here—Kraft or Jet-Puffed are the gold standards, but any quality brand works. Grab the mini marshmallows for smaller, more uniform clusters. Rice Krispies should be the original kind, not the lightly buttered version (unless you're going for a richer flavor). Butter matters too—use unsalted so you control the saltiness. For the marshmallows, Trader Joe's or Costco often have the best bulk deals, and they stay fresh for months in an airtight container.
No marshmallow creme? Melted marshmallows plus powdered sugar is a solid swap—just mix 2 cups melted marshmallows with 1/4 cup powdered sugar for a similar texture. Short on butter? Coconut oil works too, though it has a slight coconut flavor. Want more depth? Add 1/2 tsp cinnamon or 1/4 tsp almond extract to the marshmallow mixture. For the chocolate drizzle, Ghirardelli chips melt smoother than store brands. And if you're feeling fancy, swap the peanut butter for almond butter—just add 1 tbsp extra marshmallow creme to balance the richness.
Store these in an airtight container at room temperature for up to 5 days, or freeze for 3 months. The marshmallow creme sets best when the bars cool completely—30 minutes is key. For parties, cut into squares or use a cookie cutter for fun shapes. Leftovers? Reheat in 10-second bursts in the microwave to restore that gooey center. And trust me, the golden crust is worth the extra minute in the oven—it’s what makes these bars look (and taste) restaurant-quality.

Step-by-step instructions for Rice Krispie bars with marshmallow creme
Let's create the perfect balance of crunchy cereal and gooey marshmallow goodness.
Melt Butter and Sugar for the Base
In a large, heavy-bottomed saucepan, combine the 0.5 cup unsalted butter and 0.5 cup granulated sugar over medium heat. Let it melt completely, stirring occasionally with a wooden spoon. The mixture will bubble gently and begin to turn golden—this is when you'll notice the sugar dissolving completely into the butter.
Once fully melted and smooth, remove the pan from heat and stir in the 1 tsp vanilla extract and 0.5 tsp salt. This step is crucial for building the flavor foundation. The butter should be completely melted and the sugar fully incorporated before moving forward—if you see any undissolved sugar crystals, return the pan to low heat for another 30 seconds to complete the process.
Add Marshmallows and Marshmallow Creme
Return the saucepan to low heat and carefully add the 2 cups large marshmallows and 1 cup marshmallow creme. Stir constantly with a wooden spoon or silicone spatula, breaking up any large marshmallow pieces as they melt. The mixture will thicken significantly as the marshmallows dissolve—this is normal and indicates the sauce is coming together.
Continue stirring until the mixture becomes smooth and glossy, reaching a soft-ball consistency. You'll know it's ready when it coats the back of a spoon and holds its shape when dropped into cold water. This typically takes about 5-7 minutes of gentle stirring. If the mixture starts to brown or thicken too much, reduce the heat to the lowest setting to prevent burning.
Incorporate Rice Krispies and Optional Add-Ins
Remove the pan from heat and quickly stir in the 6 cups rice krispies cereal until fully coated. The cereal will absorb the marshmallow mixture immediately, creating a thick, sticky dough. At this point, you can also fold in any optional add-ins: 0.25 cup peanut butter for a nutty twist, 0.5 cup crushed nuts for texture, or both for a rich combination.
Work quickly but carefully to distribute everything evenly. If the mixture feels too dry or crumbly, add 1-2 tablespoons of milk to help bind it together. The dough should be cohesive enough to press into a pan but still soft enough to spread easily. This is where the magic happens—proper mixing ensures each bite delivers that perfect crunch and gooey balance.
Press and Set in the Pan
Lightly grease a 9x13-inch baking pan with butter or line it with parchment paper for easy removal. Press the marshmallow-cereal mixture firmly and evenly into the pan using a spatula or the back of a spoon. For extra even distribution, gently tap the pan on the counter to help settle the mixture. The surface should be smooth and level—any uneven spots will result in thicker or thinner sections when cut.
Let the bars cool and set at room temperature for 1-2 hours, or refrigerate for 30 minutes if you're in a hurry. This step is essential for developing the proper texture—rushing it will result in crumbly bars that fall apart. Once set, lift the bars out of the pan using the parchment paper for clean edges, or cut directly from the pan if you prefer.
Optional Toppings and Finishing Touches
For an extra touch of decadence, melt 0.5 cup dark chocolate chips and 0.5 cup white chocolate chips together in a microwave-safe bowl in 30-second intervals, stirring between each interval until smooth. Drizzle this mixture over the set bars in an attractive pattern, then sprinkle with 0.25 cup powdered sugar for a dusted finish. The chocolate will add a rich contrast to the sweet marshmallow base, while the powdered sugar gives a professional, bakery-style look.
Let the chocolate set completely before cutting into 16 perfect squares. Store in an airtight container at room temperature for up to 5 days, or refrigerate for up to 1 week to maintain maximum freshness. These bars are best enjoyed at room temperature, where the marshmallow creme stays soft and gooey—just as it should be!
Pro Tips For Making Rice Krispie Bar Recipe With Marshmallow Creme
- Melt Slowly, Stir Often: I learned this the hard way—dumping all the butter and marshmallows in at once leads to uneven melting and a gooey mess. Instead, add the butter first, then stir in the marshmallows one handful at a time, letting each batch melt completely before adding more. The creme will be smoother, and you’ll avoid the dreaded "lumpy" texture that ruins the whole bar.
- Toast Cereal First: Skip the raw cereal plop, and you’ll end up with a sad, soggy bar. Toast the Rice Krispies in a dry pan over medium heat for 2-3 minutes until they’re just golden—this crisps them up and cuts down on the extra butter you’ll need later. (Yes, even if you’re impatient like me, don’t skip this.)
- Chill Before Cutting: That marshmallow creme sets up like a dream when cold, but resist the urge to slice into the bars right after pouring. Let them cool completely in the pan, then pop them in the fridge for 15-20 minutes. This guarantees clean cuts instead of a sticky, crumbling disaster—trust me, your guests will notice.
- Use Extra Creme, Not Extra Butter: I used to compensate for a weak marshmallow flavor by adding more butter, but that just makes the bars greasy. Instead, go heavy on the marshmallow creme—about 1.5 cups for a standard recipe—and cut back on the butter slightly. The result? A richer, gooier center that actually tastes like s’mores, not cereal.
Common mistakes when making this recipe
Overmixing the Dough
Here’s where I see most beginners go wrong—they overmix the marshmallow-cereal mixture, turning it into a crumbly mess instead of a cohesive dough. The key is to stir just until the Rice Krispies are fully coated, about 30 seconds.
Overmixing breaks down the marshmallow creme, making the bars dry and crumbly. I’ve ruined more batches than I care to admit by stirring too long—trust the process and stop when the cereal is evenly distributed. 💫
Skipping the Cooling Time
Rushing the 1-2 hour cooling time is a recipe for disaster. I’ve seen people cut into bars too soon, only to have them crumble apart. The marshmallow creme needs time to fully set and bind with the cereal.
If you’re in a hurry, refrigerate for 30 minutes, but don’t skip this step entirely. Patience here ensures those perfect, clean cuts and that satisfying crunch.
Uneven Pressing in the Pan
Pressing the mixture unevenly leads to thick, gooey spots and thin, dry edges—no one wants that! Use a spatula to press firmly and evenly into the 9x13-inch pan, then tap the pan gently on the counter to settle the mixture.
I’ve learned the hard way that uneven pressing ruins the texture. For extra smoothness, press in two layers if needed—just let the first layer set slightly before adding the second.
Burning the Marshmallows
Heat is your enemy when melting marshmallows. Too much heat turns them into a sticky, burnt mess instead of a smooth, glossy mixture. Keep the heat on low and stir constantly. I’ve had to start over more times than I’d like to admit because the marshmallows browned too quickly.
If the mixture starts to look too thick or grainy, reduce the heat immediately and keep stirring until it smooths out.
Using the Wrong Butter
Salted butter can throw off the flavor balance, making your bars taste too salty. Always use unsalted butter and control the saltiness yourself with the 0.5 tsp kosher salt in the recipe.
I’ve made this mistake more than once, and the difference is noticeable. If you’re out of unsalted butter, use European-style butter, which has less salt than American brands.
Not Greasing the Pan Properly
A poorly greased pan means your bars will stick, making them impossible to cut cleanly. Lightly butter the pan or line it with parchment paper for easy removal. I’ve had to pry bars off with a butter knife more times than I’d like to admit—don’t let that happen to you!
If you’re using parchment, make sure it’s snug against the sides of the pan to prevent sticking.

Frequently asked questions
Can I substitute marshmallow creme with regular marshmallows?
Yes, but the texture will be slightly different. Replace the 1 cup marshmallow creme with 2 cups melted marshmallows and add 1/4 cup powdered sugar to help bind the mixture. The result will be just as delicious but may be slightly less creamy. For best results, use mini marshmallows—they melt more evenly than large ones.
How do I make these bars gluten-free?
Swap the Rice Krispies for certified gluten-free cereal like Rice Chex or gluten-free cornflakes. Keep all other ingredients the same, including the marshmallow creme and butter. The texture will be slightly different but still delicious. Always check labels to ensure no cross-contamination with gluten-containing products.
Can I make these bars ahead of time?
These bars keep well for 5 days at room temperature in an airtight container. For longer storage, freeze them for up to 3 months. Thaw at room temperature for 1-2 hours before serving. The marshmallow creme stays soft when stored properly, so there’s no need to reheat—just enjoy them straight from the container!
Why did my bars turn out crumbly instead of gooey? Crumbly bars usually mean the marshmallow mixture didn’t fully set before cutting.
What’s the best way to cut these bars neatly?
Use a sharp, hot knife for clean cuts. Dip the knife in hot water and wipe it dry between slices to prevent sticking. For extra precision, chill the bars for 10 minutes in the fridge before cutting. If you’re feeling creative, use cookie cutters to make fun shapes—just press them firmly into the set mixture.
