Desserts
This 13x9 pan Rice Krispie treats recipe delivers the perfect balance of crispy edges and moist centers—no oven required. The secret lies in the no-bake method, where melted marshmallows and butter create a velvety base that binds the cereal into a tender, golden square.
I’ve perfected this technique over years of testing, ensuring the treats stay fresh for days without turning dry or crumbly.
The 13x9 pan is key—it guarantees even baking and clean slices, while the right ratio of marshmallows to cereal (4 cups to 6 cups) prevents over-sogginess.

Perfect for gifting, potlucks, or satisfying a late-night sweet tooth, these treats also store beautifully in an airtight container. The 13x9 pan ensures uniform slices, making them ideal for sharing. Let’s get started—your taste buds (and your kitchen) will thank you.
Ingredients for rice krispie treats recipe 13x9
Pantry staples meet no-bake perfection—just butter, marshmallows, and cereal for restaurant-quality treats.
| Ingredient | Amount | Notes |
|---|---|---|
| Extra-Virgin Olive Oil 🫒 | ½ tbsp | Lightly greases the 13x9 pan |
| Unsalted Butter 🧈 | 1 cup | Salted works, but unsalted preferred |
| Mini Marshmallows 🍫 | 4 cups | Unmelted, standard size preferred |
| Rice Krispies Cereal 🍚 | 6 cups | Original flavor recommended |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality preferred |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain for even distribution |
| Dark Chocolate Chips 🍫 | ½ cup | Optional, 70% cocoa preferred |
| Coarse Sea Salt 🧂 | 2 tbsp | For sprinkling on top |
| White Chocolate Chips 🍫 | ½ cup | Optional, for variation |
| Parchment Paper 📄 | 1 sheet | For easy removal from pan |
The butter and marshmallow ratio is non-negotiable for that signature moist texture. Land O'Lakes unsalted butter melts cleanly without altering flavor, while Kraft Mini Marshmallows maintain their shape better than store-brand alternatives. For the cereal, Rice Krispies Original is essential—flavored varieties can throw off the delicate balance. If you're using salted butter, reduce the kosher salt to 0.125 tsp to avoid over-salting. Pro tip: measure marshmallows by volume after shaking the bag—it packs down significantly.
No vanilla extract? Almond extract at half the amount works in a pinch, but the flavor profile shifts slightly. Substituting regular marshmallows? Use 3.5 cups instead of 4—they're denser. For a vegan version, swap butter for coconut oil and marshmallows for vegan marshmallows (like Dandies). The chocolate chips can be omitted entirely, but if using, chop them roughly to mimic the classic texture. Pre-shredded bags often contain starch to prevent clumping, which can make the treats gummy. Store-bought chocolate chips are ideal here.
This recipe makes a 13x9 pan of treats that stays fresh for 5-7 days when stored in an airtight container at room temperature. For longer storage, slice and freeze portions on parchment paper—thaw at room temperature for 15-20 minutes before serving. The parchment paper trick (lining the pan) makes removal effortless, especially when cutting into perfect squares. If the top looks dry after pressing, lightly brush with melted butter before adding the final sprinkle of coarse sea salt—it adds crunch and balances sweetness.
Why You'll Love This Recipe
- Here’s what sold me: this costs half of store-bought treats, and I get twice the servings. Butter, olive oil, and cereal are pantry staples, and marshmallows stretch further than you’d think. Plus, leftovers? They last a week in the fridge, and I’ve even reheated slices in the toaster for a crispy upgrade. My wallet—and my taste buds—thank me.
- No-Fuss Pan Time: I swear by this 13x9 version because it’s actually one bowl, one pan—no clunky square molds or sticky fingers. Just melt butter and olive oil together, toss in marshmallows until silky, then fold in crispies. My kids "help" dump the cereal while I stir, and honestly? It’s the only treat where cleanup involves one spatula and a lick of the bowl.
- Rich, Grown-Up Twist: That olive oil swap for some butter? Game-changer. It adds a subtle depth—like a whisper of fruitiness—that makes these taste way more sophisticated than the classic. The vanilla extract ties it all together, and the mini marshmallows melt into pockets of gooey perfection. (Yes, even on a Tuesday night.)
- Party Crowd Pleaser: I make this for everything—book club potlucks, last-minute teacher gifts, or when my nephew visits. It’s the one dessert that everyone loves, even skeptics. And because it’s in a 13x9 pan, I can slice it into squares or leave it whole for dramatic presentation. (Pro tip: Drizzle with melted chocolate afterward if you’re feeling fancy.)
Step-by-step instructions for perfect 13x9 Rice Krispie treats
Here's the method for crispy-edged, moist-centered treats that stay fresh for days.
Melt Butter and Marshmallows Together
In a large, heavy-bottomed saucepan, combine the 1 cup unsalted butter and 4 cups mini marshmallows over medium-low heat. I use medium-low to prevent scorching—high heat burns marshmallows before they melt completely. Stir gently with a silicone spatula, breaking up any large clumps of marshmallows as they begin to soften.
Once the butter has fully melted and the marshmallows are completely dissolved, the mixture should be smooth and glossy with a pale golden hue. This typically takes 5-7 minutes. Remove the pan from heat immediately—you want to work with the mixture while it's still hot but before it starts to set. If it thickens too much, you can warm it briefly over low heat to restore smoothness.
Incorporate Vanilla and Salt
With the pan still off the heat, stir in the 1 teaspoon vanilla extract and ¼ teaspoon diamond crystal kosher salt. The vanilla will mingle into the mixture almost instantly, while the salt begins to dissolve. I like to let it sit for 30 seconds to ensure even distribution—this prevents any lingering salt crystals that could make a bite too harsh.
If you're using the ½ cup dark chocolate chips or ½ cup white chocolate chips, add them now. The residual heat from the marshmallow mixture will begin to soften them slightly, making them easier to distribute evenly later. Stir gently to prevent melting too much before mixing with the cereal.
Grease the Pan and Mix in Cereal
Line a 13x9-inch baking dish with the 1 sheet parchment paper, leaving a slight overhang on two sides for easy removal later. Lightly brush the bottom and sides with the ½ tablespoon extra-virgin olive oil—this ensures the treats release cleanly without sticking. I use a pastry brush for even coverage.
Quickly transfer the marshmallow mixture to the prepared pan. Using a rubber spatula, fold in the 6 cups rice krispies cereal until fully coated. Work efficiently—you have about 2 minutes before the mixture starts to set. Press the mixture firmly and evenly into the pan using the spatula, creating a smooth, level surface. The edges should be slightly thicker than the center to ensure crispy edges.
Add Toppings and Set
Sprinkle the 2 tablespoons coarse sea salt evenly over the top of the treats. I like to use a fine-mesh sieve for an even distribution—this prevents any one area from becoming overly salty. If using chocolate chips, press them lightly into the surface so they adhere during the setting process.
Let the treats cool and set at room temperature for 2 hours. This is critical—they need undisturbed time to firm up enough to slice cleanly. I resist the urge to speed this up in the fridge, as it can make them too dense. After 2 hours, the edges should be firm to the touch, and the center should hold its shape when pressed gently with a finger.
Cut and Serve
Using a sharp, 8-inch knife, cut the treats into 16 equal squares (about 2x2 inches each). For clean cuts, dip the knife in hot water between slices and wipe it dry. This prevents the treats from sticking and ensures straight edges. The knife should glide through with minimal resistance—if it feels tough, let them set another 15-30 minutes.
Serve immediately or store in an airtight container at room temperature for up to 5 days. For longer storage, freeze for up to 3 months. The treats will stay moist and chewy in the center with crispy edges—exactly as promised. If they soften over time, simply let them sit at room temperature for 10 minutes before serving to restore their texture.
Pro Tips For Making Rice Krispie Treats Recipe 13x9
- COAT THE PAN FIRST: Drizzle that extra-virgin olive oil (yes, the whole 2 tablespoons) into the 13x9 pan before melting the butter. I learned this the hard way—skipping it makes the marshmallow-butter mix stick like glue, and you’ll end up with a gummy mess instead of clean slices. Trust me, the oil creates a nonstick barrier that actually works better than parchment paper here.
- MELT BUTTER LOW AND SLOW: Unsalted butter burns faster than you’d think, especially when mixed with olive oil. Melt it over medium-low heat, stirring constantly, until it’s just smooth—not golden, not bubbling like crazy. If you rush it, the marshmallows will turn grainy before they melt, and your treats will taste like a science experiment gone wrong.
- USE A SILICON SPATULA: That marshmallow-butter mix clings to wooden spoons like it’s auditioning for a horror movie. Grab a heatproof silicone spatula instead—it scrapes every last bit out of the pan without tearing the cereal apart. I used to lose a third of the mixture to stubborn clumps; this tool cut my waste in half.
- PRESS FAST, RELEASE GRADUAL: Dump the hot mix into the pan and press it down hard with buttered hands (or a buttered spatula) for 30 seconds—no half-hearted patting. Then, let it sit covered for 10 minutes before slicing. The first batch I cut too soon? Crumbled like sad cereal. Waiting guarantees clean edges and a chewy center.
Flavor customization for rice krispie treats recipe 13x9
Citrus Zest Twist
Brighten up your treats with 1 teaspoon lemon or orange zest mixed into the marshmallow-butter mixture. The citrus oils add a refreshing contrast to the sweetness, making them perfect for summer gatherings.
I find that lemon zest works best with white chocolate chips, while orange zest pairs beautifully with dark chocolate. Add the zest after removing the pan from heat to preserve its aromatic oils. 🍋
Spiced Variations
For a cozy autumn twist, stir in ½ teaspoon cinnamon and ¼ teaspoon nutmeg with the vanilla extract. This creates a warm, spiced treat that’s perfect for holiday parties. For a smoky depth, add ¼ teaspoon smoked paprika—it’s subtle but adds complexity.
I’ve also experimented with ½ teaspoon cardamom for a Middle Eastern-inspired flavor, which pairs wonderfully with white chocolate. 🌶️
Cookie Dough Swirl
Transform your treats into a cookie dough-inspired delight by mixing in ½ cup chocolate chip cookie dough (homemade or store-bought) with the cereal. Press half the cereal mixture into the pan, swirl in the cookie dough with a knife, then top with the remaining cereal.
For extra indulgence, add ¼ cup crushed pretzels on top before pressing down. This variation is a crowd-pleaser, especially for kids or cookie lovers. 🍪
Nutty Crunch Add-Ins
For texture and protein, fold in ½ cup chopped pecans or walnuts with the cereal. Toast the nuts in a dry pan over medium heat for 3-4 minutes until fragrant, then let them cool before mixing. I recommend pecans for a buttery richness or walnuts for a toastier bite.
For a sweeter nut option, use chopped candied pecans—just reduce the marshmallow amount by ½ cup to balance the extra moisture. 🌰
Boozy Adult Twist
Elevate your treats with a splash of booze—add 1 tablespoon bourbon, rum, or espresso liqueur to the marshmallow mixture. The alcohol burns off during cooking, leaving behind a subtle depth of flavor.
I love using vanilla-infused bourbon for a sophisticated touch or Kahlúa for a mocha-inspired treat. Pair with dark chocolate chips for a decadent dessert. 🍷
Seasonal Fruit Infusions
Incorporate seasonal fruit into your treats by mixing in ½ cup finely chopped dried cranberries or apricots with the cereal. For a fresh twist, fold in ¼ cup freeze-dried strawberries or raspberries—they add a chewy texture and vibrant color.
I recommend using freeze-dried fruit because it holds up better than fresh. This variation works especially well with white chocolate chips for a fruity, creamy combination. 🍓

Frequently asked questions
Why does your recipe use a 13x9 pan instead of the classic square pan?
The 13x9 pan creates a more substantial treat with even baking and cleaner slices. The larger surface area ensures crispy edges while maintaining a moist center, unlike the classic square pan which often results in uneven texture. Plus, the 16 equal squares are perfect for portion control and gifting!
Can I make these treats without butter?
Yes! For a dairy-free version, substitute the 1 cup butter with 1 cup coconut oil (melted) or 1 cup vegan butter. The texture will be slightly softer but still delicious. Just ensure your marshmallows are vegan-friendly too—regular marshmallows contain gelatin.
How do I prevent the treats from sticking to the pan?
Line the pan with parchment paper (as in the recipe) and brush the bottom with ½ tbsp olive oil. For extra insurance, lightly oil the parchment too. If they still stick slightly, let them cool 10 minutes longer before removing—they'll release more easily when fully set.
Why did my treats turn out too dry?
Over-melting the marshmallows or using too much cereal (more than 6 cups) causes dryness. Always melt on medium-low heat and remove immediately when smooth. For every ½ cup extra cereal, reduce marshmallows by ¼ cup to maintain moisture balance.
Can I make these treats ahead of time?
They stay fresh in an airtight container for 5-7 days at room temperature. For longer storage, slice and freeze portions on parchment—thaw at room temperature for 15-20 minutes before serving. The texture actually improves after 24 hours as flavors meld!
