Rice Krispie Treats are the no-bake, four-ingredient treat that disappears the second I set them on the counter, and my girls beg for a batch every time we have a rainy afternoon with nothing to do. The secret is loading in extra marshmallows so they stay soft and gooey for days. If you love an easy sweet like our puppy chow, these are about to become your new go-to.

Quick Answer
Melt butter in a large pot, then stir in most of the mini marshmallows until smooth. Take it off the heat, mix in vanilla and a pinch of salt, then fold in the rice krispies cereal along with a handful of reserved marshmallows for extra gooey pockets. Press the mixture gently into a lined pan, let it set for a couple of hours, then cut into bars. The whole thing takes about 15 minutes of hands-on time.

Why This Recipe Works
Click to see the technique science
- Extra marshmallows keep them soft. Reserving a few cups of marshmallows to fold in at the end means melty pockets and treats that never go hard.
- Low and slow melting. Melting the butter and marshmallows over medium-low heat keeps them creamy instead of stiff and grainy.
- A splash of vanilla and salt. These two pantry staples take the flavor from plain to bakery-level in one stir.
- Do not pack them down. Gently pressing the mixture keeps the treats light and chewy instead of dense and tough.
- Salted butter does double duty. It adds richness and balances the sweetness in every single bite.
- A big pan means perfect thickness. A 10×15 jelly roll pan gives you treats that are tall enough to satisfy but not overwhelming.
Why You’ll Love This Recipe
- They come together in one pot with just a handful of ingredients you probably already have.
- No oven required, which makes them perfect for hot days and last-minute cravings.
- They are endlessly customizable, from monster rice krispie treats to brown butter or sprinkles.
Key Ingredients
Just five simple ingredients stand between you and a pan of gooey treats. Here is why each one matters.
- Mini marshmallows: The star of the show. Mini ones melt faster and more evenly than the big ones, and reserving some keeps the treats extra gooey.
- Salted butter: Adds richness and a subtle savory note that balances out all that sweetness.
- Rice krispies cereal: Use a fresh box for the best crunch. Stale cereal makes for sad, soft treats.
- Vanilla extract: A small splash adds warmth and rounds out the marshmallow flavor.
- Fine sea salt: Just a pinch sharpens the flavor and keeps the treats from tasting flat.

Variations and Substitutions
Once you master the base recipe, the fun begins. Try one of these easy spins.
- Stir in 1 cup of M&Ms, sprinkles, or mini chocolate chips after the cereal for a pop of color.
- Brown the butter first for a nutty, caramel-like depth, like our brown butter rice krispie treats.
- Drizzle the cut bars with melted chocolate or peanut butter for an extra special treat.
- Swap in a different cereal or fold in crushed cookies for a fun twist, like our smores cereal treats.
How to Make Rice Krispie Treats
- Melt the butter in a large pot over medium-low heat.
- Add most of the mini marshmallows, reserving about 4 cups for later.
- Stir constantly until smooth, take off the heat, then mix in the vanilla and salt.
- Fold in the rice krispies cereal and the reserved marshmallows until everything is coated.
- Gently press the mixture into a foil-lined, greased pan without packing it down.
- Let the treats set for at least 2 hours, then cut into bars and serve.
Recipe Tips & Tricks
- Use fresh marshmallows. Old, dried-out marshmallows will not melt smoothly and make the treats tough.
- Grease your hands. Lightly spray your hands or spatula with cooking spray to press the sticky mixture without a mess.
- Do not overheat. Take the pot off the heat as soon as the marshmallows melt to keep the treats soft.
- Line the pan with foil. A foil sling lets you lift the whole slab out for clean, easy cutting.
- Reserve marshmallows for gooey pockets. Folding in whole marshmallows at the end is the secret to soft treats.
- Cut with a greased knife. Wipe and re-grease the blade between cuts for neat, clean squares.
Serving Ideas and Suggestions
Rice Krispie Treats are perfect just as they are, stacked on a plate next to a cold glass of milk for an after-school snack or lunchbox surprise.
For a party, cut them into fun shapes with cookie cutters or dip the edges in melted chocolate and sprinkles. They are always a hit alongside other no-bake favorites like our puppy chow and monster rice krispie treats.
Wrap individual squares in plastic wrap for grab-and-go treats, or pile them on a dessert board with brownies and cookies for a crowd. They also make a sweet, easy homemade gift.

If you roll them thin, then melt butter, chocolate and some marshmallows, you can spread this over the RK layer, then roll it up like a pinwheel. Refrigerate until set, then slice them. There are never leftovers.
