Ingredients for rice krispie treats recipe made with 16 oz marshmallows
Six crispy cups of cereal plus melty 16 oz marshmallows—this is the magic combo for perfect treats every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍚 | 6 cups | Original, not honey-nut variety |
| Large Marshmallows 🍬 | 16 oz | Mini marshmallows work too |
| Unsalted Butter 🧈 | ½ cup | Full-fat for best texture |
| Granulated Sugar 🍚 | 1 tbsp | Optional for extra crunch |
| Kosher Salt 🧂 | ¼ tsp | Fine grain preferred |
| Vegetable Oil 🫒 | 1 tbsp | For greasing pan |
| White Chocolate Chips 🍫 | ½ cup | Optional for topping |
| Melted Semi-Sweet Chocolate 🍫 | ½ cup | Optional for drizzling |
The marshmallows are non-negotiable here. 16 oz is the golden amount—too little and they're dry, too much and they get gummy. Kellogg's Original or store-brand work fine, but skip the mini marshmallows if you want that classic texture. Butter matters too: unsalted ensures you control the saltiness. I always grab Land O'Lakes or Organic Valley from the grocery store's dairy section. Pro tip: don't melt the butter too fast—low heat prevents burning. The cereal? Rice Krispies only—no substitutes here unless you're feeling adventurous with cornflakes.
No marshmallows? Mini marshmallows at 20 oz work in a pinch (just adjust baking time), but nothing beats the classic size. Butter substitute? Vegan butter works too, though texture might differ slightly. The salt is key—skip it and they'll taste bland. For the optional toppings, Trader Joe's white chocolate chips melt beautifully, and Ghirardelli chocolate gives that restaurant-quality drizzle. Want extra crunch? Sprinkle crushed cereal on top before they set—just press lightly so they stick.
These stay fresh for 5-7 days in an airtight container at room temperature. For longer storage, wrap tightly in plastic wrap and freeze for up to 3 months. I always make a double batch because they disappear fast—perfect for parties or sneaking into lunchboxes. The secret to easy slicing? Let them cool completely before cutting. Use a sharp knife and dip it in hot water every few slices for clean cuts. Leftovers? Toss them in the toaster for crispy Rice Krispie toast—absolute game-changer.

Step-by-step instructions for perfect Rice Krispie treats
Here's how to make these crowd-pleasing treats with melty marshmallow centers every time.
Prepare Your Pan and Ingredients
Line an 8-inch square baking pan with parchment paper, leaving an overhang on all sides for easy removal later. Lightly grease the parchment with the 1 tablespoon vegetable oil using a paper towel—this prevents sticking and makes cleanup a breeze. I like to use a silicone brush for even coverage.
In a large, heavy-bottomed saucepan, combine the 16 oz large marshmallows, ½ cup unsalted butter, 1 tablespoon granulated sugar, and ¼ teaspoon kosher salt. These ingredients create the gooey base that binds everything together. Make sure your marshmallows are the large, fluffy kind—they melt more evenly than mini marshmallows.
Melt and Combine Over Low Heat
Place the saucepan over low heat and stir gently with a wooden spoon until the mixture begins to melt. You'll see the marshmallows soften first, then gradually turn into a smooth, glossy liquid. This should take about 5-7 minutes—don't rush it, or you'll risk burning the marshmallows.
Once fully melted, remove the pan from heat and let it sit for 2 minutes to cool slightly. This resting period prevents the marshmallow mixture from setting too quickly when you add the cereal. The mixture should look like thick, golden syrup—if it's too runny, return it to the heat for 30 seconds to thicken slightly.
Fold in the Rice Krispies
Working quickly, stir in the 6 cups rice krispies cereal using a wooden spoon or silicone spatula. You'll want to fold gently but thoroughly—just until all the cereal is coated in the marshmallow mixture. Overmixing can create a gummy texture, so stop as soon as every piece of cereal is incorporated.
Transfer the mixture to the prepared pan and press it down firmly and evenly with a greased spatula or the back of a spoon. I press down in a crisscross pattern to ensure even distribution and a smooth surface. The treats should look dense and compact—this ensures clean slices later.
Cool and Cut for Perfect Squares
Let the treats cool at room temperature for 1 hour before attempting to cut them. This cooling period allows the marshmallow mixture to set properly, making for cleaner slices. If you're in a hurry, you can refrigerate them for 30 minutes to speed up the process.
Once fully set, use the parchment overhang to lift the treats out of the pan. Using a sharp knife or pizza cutter, cut the treats into 16 equal squares (about 2-inch by 2-inch each). For extra flair, you can drizzle the tops with the ½ cup melted semi-sweet chocolate or sprinkle with the ½ cup white chocolate chips while they're still warm.
Optional Add-Ins and Serving
For a festive touch, press additional toppings like sprinkles, crushed pretzels, or chopped nuts into the top of the treats before they cool completely. These add-ins add texture and visual appeal without altering the classic recipe.
Store any leftovers in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. These treats are best enjoyed warm—just pop them in the microwave for 10-15 seconds to restore that gooey texture. Serve with a glass of cold milk for the ultimate nostalgic experience!
Pro Tips For Making Rice Krispie Treats Recipe Made With 16 Oz Marshmallows
- Use Medium Heat for Marshmallows: I learned this the hard way—high heat turns 16 oz of marshmallows into a sticky disaster. Keep the pan on medium and stir constantly; you want smooth, creamy melted marshmallows, not burnt sugar bombs.
- Toast the Rice Krispies First: Skip the soggy cereal by lightly toasting the Rice Krispies in a dry pan for 2-3 minutes before mixing. The extra crunch makes all the difference, and it prevents the treats from turning gummy.
- Salt the Butter: Add the full ¼ teaspoon kosher salt to the butter while melting, not just to the cereal. This ensures even flavor distribution—no more bland pockets where the salt gets lost in the mix.
- Press Firmly Before Cutting: Don’t rush the final press—pack the mixture into the pan tightly for clean slices. Let it sit for 10 minutes before cutting, or the treats will crumble like wet sand. (Yes, even if you’re impatient like me.)
Creative variations of this rice krispie treats recipe made with 16 oz marshmallows
Chocolate-Dipped Luxury
Elevate your treats with a rich chocolate drizzle—melt ½ cup semi-sweet chocolate (I love Ghirardelli for its smooth texture) in a microwave-safe bowl in 30-second bursts, stirring between each. Once the treats are cut, pour the melted chocolate over the top and let it drip down the sides.
For extra decadence, sprinkle crushed almonds or sea salt flakes while the chocolate is still wet. 🍫
White Chocolate Swirl
For a creamy contrast, melt ½ cup white chocolate chips (like Trader Joe’s brand) and drizzle it in zigzag patterns across the warm treats before they fully set.
Press in mini chocolate chips or crushed macadamia nuts for added crunch. This variation looks stunning for holidays or special occasions—it’s like a dessert within a dessert!
Peanut Butter Crunch
Stir ½ cup creamy peanut butter (like Jif or Skippy) into the melted marshmallow mixture before adding the cereal. The peanut butter adds a savory-sweet depth that pairs perfectly with the marshmallow’s gooeyness.
For extra flair, top with chopped peanuts or peanut butter cups before pressing into the pan. This twist is a crowd-pleaser at potlucks! 🥜
Cinnamon Sugar Spice
Mix 1 tablespoon cinnamon and 1 tablespoon granulated sugar into the melted marshmallow mixture for a warm, spiced flavor. After pressing the treats into the pan, sprinkle the top with an extra ½ teaspoon cinnamon and 1 tablespoon sugar for a caramelized crust.
These taste like a cross between Rice Krispie treats and cinnamon toast—perfect for fall or winter gatherings. ✨
Cookie Dough Bites
Fold ½ cup cookie dough (homemade or store-bought, like Betty Crocker) into the marshmallow mixture after adding the cereal. Press the treats into the pan as usual, then swirl in chocolate chips and mini M&M’s on top.
The cookie dough pockets add a soft, chewy surprise in every bite—like a dessert hybrid! 🍪
Seasonal Fruit Twist
For a lighter, fruity variation, fold ½ cup finely chopped dried fruit (like cranberries or apricots) into the marshmallow mixture. Top with white chocolate drizzle and toasted coconut flakes for a tropical vibe. This works especially well in summer when you want something fresh but still indulgent. 🍍

Frequently asked questions
Why do my Rice Krispie treats turn out gummy instead of crispy? Gummy treats usually mean the marshmallow mixture didn't cool enough before adding cereal or was overmixed. Always let the melted marshmallow mixture sit off heat for 2 minutes to thicken slightly, then fold in cereal just until combined. Overmixing creates air pockets that trap moisture. Also,
Can I use mini marshmallows instead of large ones?
Yes, but you'll need 20 oz of mini marshmallows to match the volume of 16 oz large marshmallows. Mini marshmallows melt faster and may require slightly less butter. The texture will be slightly different—minis create a finer crumb but still work well. Just watch the heat closely to prevent burning.
How do I fix treats that didn't set properly?
If your treats are too soft, try pressing them back into the pan and refrigerating for 30 minutes to firm up. For extra structure, sprinkle powdered sugar on top before pressing—it absorbs excess moisture. If they're already cut, place them on a wire rack in a 200°F oven for 10 minutes to crisp up slightly.
What's the best way to store these treats?
For short-term storage, keep them in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually in plastic wrap and freeze for up to 3 months. To prevent sogginess, place a piece of parchment paper between layers. Thaw at room temperature or microwave for 10 seconds to restore gooeyness.
Can I make these treats without butter?
Yes, but the texture will differ. Use ½ cup coconut oil or vegan butter for a dairy-free version. The treats will be slightly softer and less crispy. For best results, choose a butter substitute with similar fat content. You may need to adjust baking time slightly if using coconut oil, as it has a lower melting point.
