Ingredients for rice krispie treats recipe 12 oz marshmallows
These nostalgic treats come together with just nine ingredients—no baking required for that perfect crunchy-creamy magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Mini Marshmallows 🍡 | 12 oz | Standard size for perfect texture |
| Rice Krispies Cereal 🍚 | 6 cups | Original flavor preferred |
| Unsalted Butter 🧈 | ½ cup | Cut into small cubes for even melting |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality extract |
| Salt 🧂 | ½ tsp | Kosher or sea salt preferred |
| White Chocolate Chips 🍫 | ½ cup | Optional for extra indulgence |
| Non-Stick Cooking Spray 💧 | 1 spray | For easy release from pan |
| Granulated Sugar 🍚 | 1 tbsp | Optional for extra crisp edges |
| Aluminum Foil 📄 | 1 sheet | For lining the pan |
The marshmallows are the star here. 12 oz of mini marshmallows gives you that ideal gooey-to-crisp ratio—Trader Joe’s or Kroger carry them in bulk, which saves money for batch cooking. For the butter, Land O’Lakes unsalted melts beautifully without adding extra salt. The vanilla extract should be pure—McCormick or Goya are reliable brands. Pro tip: measure your cereal by weight if possible—6 cups by volume can vary by brand, but 6 oz ensures consistency. The Rice Krispies should be the original flavor; other varieties can alter the texture.
No vanilla extract? Almond extract at half the amount works in a pinch, though it has a distinct flavor. Short on butter? Coconut oil melts similarly, but it adds a subtle coconut taste. Want to skip the white chocolate? Melted caramel sauce drizzled on top adds a similar richness. For extra crisp edges, sprinkle 1 tbsp granulated sugar over the top before pressing into the pan. The non-stick cooking spray is non-negotiable—it ensures your treats release cleanly from the pan. If you’re making these for a party, double the recipe; they disappear fast!
Store your treats in an airtight container at room temperature for up to 5 days, though they’re best enjoyed fresh. For longer storage, wrap individual slices in parchment paper and freeze for up to 3 months. The aluminum foil lining your pan doubles as a makeshift storage container—just press the foil over the treats and fold the edges. These treats reheat beautifully; pop them in the oven at 300°F for 5 minutes to restore that warm, gooey center. Leftovers? Toss them in a lunchbox—they’re a hit with kids (and adults!).

Step-by-step instructions for no-bake Rice Krispie treats
Here's how to create perfectly crispy, no-bake treats that taste like childhood nostalgia—just follow these simple steps.
Melt Butter and Marshmallows Until Silky
In a large, heavy-bottomed saucepan, combine the 0.5 cup unsalted butter (cut into small cubes) and the 12 oz mini marshmallows. I like to use a saucepan with a helper handle for easy stirring—this prevents spills when the mixture gets bubbly. Place the pan over medium-low heat and let it melt slowly.
Stir constantly with a wooden spoon or silicone spatula, breaking up any large marshmallow clumps as they melt. You'll know it's ready when the mixture becomes smooth and glossy, with no visible butter chunks. This usually takes about 8-10 minutes. Real talk: don't rush this step—uneven melting leads to gummy treats. The mixture should coat the back of a spoon like warm caramel.
Once fully melted, remove the pan from heat and immediately stir in the 1 tsp vanilla extract and 0.5 tsp salt. Let the mixture sit for 1 minute to cool slightly—this prevents the marshmallow mixture from cooking the cereal too quickly and turning it mushy.
Mix in Cereal and White Chocolate Chips
Working quickly, add the 6 cups rice krispies cereal to the marshmallow mixture. Use a wooden spoon to gently fold everything together until the cereal is completely coated. I promise, it'll look like too much cereal at first, but trust me—it all absorbs perfectly. If you're using the 0.5 cup white chocolate chips, fold those in now too.
Here's the thing—don't overmix. Just combine until every piece of cereal has a thin coating of marshmallow. Overmixing develops gluten in the cereal, which makes the treats denser. The mixture should look like a thick, sticky wet sand consistency. If it seems dry, add 1-2 teaspoons of water to help bind everything together.
Press into Pan for Perfect Shape
Lightly spray a 9x13-inch baking dish with the non-stick cooking spray (I use a full can spray for even coverage). Line the bottom with the sheet of aluminum foil, spraying the foil as well for easy release later. This step ensures your treats don't stick and come out in one perfect slab.
Transfer the marshmallow-cereal mixture to the prepared pan and press down firmly and evenly using a greased spatula or the back of a wooden spoon. I like to press in a back-and-forth motion, making sure to get into all the corners. For extra crispy edges, sprinkle the 1 tbsp granulated sugar evenly over the top before pressing.
Press until the mixture reaches about ½-inch thickness throughout. This ensures even cooking and that perfect crunch. If you have any leftover mixture, you can press it into a smaller pan for individual treats or more squares.
Cut and Cool for Maximum Crunch
Let the treats cool completely at room temperature for 1-2 hours. This is where patience pays off—the longer they cool, the crispier they become. I know it's tempting to cut them early, but resist! The texture transforms dramatically during this time.
Once fully cooled, use a sharp knife to cut the treats into squares or rectangles (about 2x2 inches each). For cleaner cuts, dip the knife in hot water between each cut—this prevents the cereal from sticking to the blade. The treats should hold their shape when lifted, with crisp edges and a soft, pillowy center.
Store any leftovers in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. The crispiness diminishes slightly over time, but they'll still be delicious. Enjoy your perfect no-bake treats—crispy outside, gooey inside, just like you remember!
Pro Tips For Making Rice Krispie Treats Recipe 12 Oz Marshmallows
- Use a Heavy Pot: I learned this the hard way—light pots slide on stovetops, and marshmallows will boil over if you’re not paying attention. A cast-iron skillet or deep stainless steel pot keeps things stable, so you can focus on stirring without a spill disaster.
- Toast the Cereal First: Skip the "just dump it in" approach—toss the Rice Krispies in a dry skillet over medium-low heat for 2-3 minutes until they smell toasty. This adds depth of flavor and prevents the final product from tasting like plain cereal.
- Salt the Butter Early: After burning three batches where the treats tasted bland, I started dissolving the salt into the melted butter before adding marshmallows. It distributes evenly, and you won’t end up with clumps of salt in your finished treats.
- Press Firmly, Then Rest: Pack the mixture into the pan with a rubber spatula—don’t just shove it in. Once shaped, let it sit (covered with foil) for 5-10 minutes before cutting. This keeps the edges from crumbling when you slice it.

Frequently asked questions
Why do my Rice Krispie treats turn out gummy instead of crispy? Gummy treats usually happen when the marshmallow mixture cools too quickly or isn't pressed firmly enough.
Can I substitute regular marshmallows for mini marshmallows?
Use 10 large marshmallows (about 12 oz total) instead of mini marshmallows—they'll melt the same way. Just chop them into smaller pieces first so they melt evenly. The texture will be identical, but mini marshmallows give a slightly finer crumb.
How do I make these treats without butter?
Replace the 0.5 cup butter with 0.5 cup coconut oil or vegetable shortening for a dairy-free version. Coconut oil adds a subtle coconut flavor, while shortening keeps the texture neutral. Melt the oil first, then proceed with the recipe as written.
Can I make these treats ahead of time?
Yes! These treats actually taste better the next day. Press them into the pan and let cool completely, then wrap tightly in plastic wrap or store in an airtight container. They'll keep for 5 days at room temperature or 3 months in the freezer. For extra crispiness, reheat slices at 300°F for 5 minutes before serving.
What's the best way to cut them neatly?
Use a sharp knife and dip it in hot water between cuts to prevent sticking. For cleaner edges, press the knife straight down and wipe it clean after each cut. If the treats are fully cooled, they should cut into perfect squares with minimal crumbling.
