Rice Krispie treats can go wrong in two directions: dry and crumbly, or so sticky that they stretch instead of holding their shape. This recipe lands in the middle. Seven cups of crispy rice cereal are coated with 16 ounces of marshmallows and six tablespoons of salted butter, giving the bars a soft chew with plenty of crunch.
The ratio helps, but the method matters just as much. Keep the heat low, take the marshmallows off the stove before they have completely melted, and press the mixture into the pan gently. Those three details keep the treats light instead of hard and compact.
Rice Krispie Treats Recipe
Prep time: 10 minutes
Cook time: 10 minutes
Cooling time: 30 minutes
Yield: 24 treats
Ingredients
- 7 cups Rice Krispies cereal or another crispy rice cereal
- 16 ounces (454 g) fresh marshmallows, mini or standard size
- 6 tablespoons (85 g) salted butter
- Softened butter or nonstick cooking spray, for the pan
Instructions
1. Prepare the pan and cereal
Line a 9 x 13-inch pan with parchment paper, leaving enough overhang to lift out the treats later. Lightly grease the parchment and the sides of the pan. Measure the cereal into a large bowl so it is ready as soon as the marshmallows melt.
2. Melt the butter
Place the butter in a large pot and melt it over low heat. Swirl or stir occasionally so it melts evenly without browning.
3. Soften the marshmallows
Add the marshmallows and stir frequently over low heat. When most have melted but a few soft lumps remain, remove the pot from the burner. Continue stirring off the heat until the mixture is smooth. The remaining warmth will finish melting the marshmallows without overheating them.
4. Coat the cereal
Immediately pour the marshmallow mixture over the cereal. Fold with a silicone spatula until the cereal is evenly coated and no dry pockets remain. Stop mixing once everything comes together so the cereal does not become crushed.
5. Shape the treats
Transfer the mixture to the prepared pan. Use a lightly greased spatula or a piece of parchment paper to ease it into an even layer. Press only firmly enough to fill the corners. Packing it down hard will make the treats dense.
6. Cool and cut
Leave the pan at room temperature for at least 30 minutes. Lift out the slab using the parchment, then cut it into 24 squares. For cleaner cuts, lightly grease the knife and wipe it between slices.
Why This Ratio Works
The familiar cereal-box recipe uses less butter and marshmallow for a similar amount of cereal, which can produce thinner, drier bars. Here, 16 ounces of marshmallows provide enough coating for seven cups of cereal without turning the treats gummy. Six tablespoons of salted butter soften the sweetness and give the mixture enough richness without leaving it greasy.
A 9 x 13-inch pan also gives the bars enough height to feel substantial. An 8- or 9-inch square pan is better for the smaller batch below.
What Makes Rice Krispie Treats Soft Instead of Hard?
High heat is usually the problem. Marshmallows are mostly sugar, and cooking them too aggressively creates a hotter, stickier mixture that sets much firmer as it cools. Melt them slowly and finish stirring them away from the burner.
How the mixture goes into the pan matters too. Pressing hard crushes the cereal and removes the small air pockets that give the bars their lighter texture. Level the top, but do not compact it.
Fresh marshmallows also melt more smoothly. An opened or older bag may look fine but can produce a thick mixture that is difficult to spread.
Ingredient Notes
Marshmallows
Measure marshmallows by weight when possible because cup measurements vary with their size and brand. Mini marshmallows melt faster, but standard marshmallows work just as well. If using large ones, stir patiently rather than increasing the heat.
Salted butter
Salted butter keeps the bars from tasting flat or overly sweet. European-style butter gives a slightly richer flavor, but it is not necessary. Any good salted butter will work.
Crispy rice cereal
Kellogg’s Rice Krispies give the recipe its familiar flavor, but another crisp rice cereal can be used. Texture varies between brands, so fold gently and avoid automatically adding extra cereal. The finished mixture should be thoroughly coated but still easy to spread.
Microwave Method
Prepare the pan and measure the cereal before starting. Place the butter in a very large microwave-safe bowl and heat it for about 30 seconds, or until mostly melted.
Add the marshmallows and microwave for 45 seconds. Stir thoroughly, scraping the bottom of the bowl. If the marshmallows are still too firm to stir smooth, continue heating in 15-second intervals. Stop as soon as the mixture comes together because overheating can make the finished bars hard.
Fold in the cereal, spread the mixture gently in the prepared pan, and cool for at least 30 minutes before cutting.
Smaller-Batch Rice Krispie Treats
For an 8- or 9-inch square pan, use:
- 4⅔ cups crispy rice cereal
- 10 ounces (283 g) marshmallows
- 4 tablespoons (57 g) salted butter
Follow the same instructions. An 8-inch pan will produce thicker squares, while treats made in a 9-inch pan will be a little thinner.
Tips That Make a Difference
- Measure before heating: Once the marshmallow mixture is ready, it begins setting quickly. Have the pan and cereal waiting.
- Use low heat: Turning up the burner saves very little time and is the most common reason the treats become hard.
- Remove the pot early: A few soft marshmallow lumps are fine. They will disappear as you stir off the heat.
- Fold just until coated: Excessive mixing can crush the cereal and make the bars heavy.
- Press lightly: Spread the mixture into the corners without compressing it.
- Let the slab set before cutting: Warm treats are sticky and difficult to slice neatly.
Storage
Keep Rice Krispie treats in an airtight container at room temperature. They have the best texture during the first three days, although they can be kept for up to five days. Place parchment or wax paper between layers so they do not stick together.
Avoid refrigerating them for routine storage because the cold firms the butter and makes the bars feel harder. For longer storage, wrap individual squares tightly and freeze them in an airtight container for up to six weeks. Let them thaw at room temperature while still wrapped.
Are Rice Krispie Treats Gluten-Free?
Standard Kellogg’s Rice Krispies are not considered gluten-free because they contain barley malt flavoring. To make gluten-free marshmallow treats, choose a crispy rice cereal labeled gluten-free and check the labels on the marshmallows and cooking spray as well.
For another quick dessert that does not need the oven, try these white chocolate Oreo truffles. If you are in the mood for an easy baked bar instead, these chocolate chip cookie bars use a boxed cake mix and only a few ingredients.
