Key Ingredient Notes

You will need 5 simple ingredients: mini marshmallows, butter, Rice Krispie cereal, vanilla extract, and a pinch of salt for balance. For the full ingredient amounts, scroll down to the printable recipe card.

For the softest, gooiest Rice Krispie treats, always use fresh marshmallows. Older ones donโ€™t melt as well and can make the bars tough or rubbery. Fresh marshmallows melt smoothly, taste better, and give you that perfect melt-in-your-mouth texture.

Browning the butter makes a big difference in Rice Krispie treats because it adds layers of flavor that plain melted butter simply can’t provide. When you brown butter, you’re gently cooking the milk solids in the butter until they turn golden and develop a deep, nutty aroma.

Instead of just sweet and marshmallowy, the flavor of your marshmallow treats becomes more balanced, with a toasted, nutty and almost caramel-like flavor.

How To Make Brown Butter Rice Krispie Treats

Making Brown Butter Rice Krispie Treats is a super simple process with just 4 simple steps: brown the butter, melt in the marshmallows, stir in the cereal, and form into to a greased pan. To make sure they turn out perfectly, I have indulged a quick step-by-step recipe overview with a few tips and tricks. Please scroll down to the printable recipe card for full instructions.

Start by browning the butter, carefully cooking it over medium heat until it foams, turns golden, and starts to smell nutty. Watch closely, as it can quickly go from brown to burnt. Follow my post for how to brown butter if it’s your first time!

A wooden spoon stirs a creamy, melted marshmallow and brown butter mixture with visible marshmallow lumps in a white pot.

Once the butter is browned, immediately stir in two bags of marshmallows. Melt them slowly, stirring constantly, to preserve a soft, gooey texture. Rushing this step over high heat can make the mixture stiff and your treats hard.

Once the marshmallows are fully melted, stir in the vanilla extract and salt. Quickly (but carefully!) fold in the rice cereal to coat every piece without crushing it. Then fold in the last bag of mini marshmallows.

Immediately transfer the mixture into a greased pan. Don’t press down firmly, just lightly pat the mixture into an even layer with a greased spatula. This is super important to keep the texture soft, fluffy, and airy.

Let the treats set at room temperature until fully set, about an hour, then slice them into bars before serving. I always save a little in the pot so I can sneak a few bites while I wait. 😉

Frequently Asked Questions

Can I only use 2 bags of marshmallows?

Yes, you can use two bags for the base and skip mixing in the third bag if you prefer. The extra whole marshmallows add to the softness, but are optional!

What size pan should I use for this recipe?

You will want to use a 9×13 pan as this makes a large amount. If you want to halve the recipe, you can use an 8ร—8 or 9ร—9 pan instead to keep them thick.

Why are my Rice Krispie treats hard instead of soft?

This can happen for two possible reasons… #1 You over heated the marshmallows or used old/stale ones. Always melt the marshmallows slowly over low heat! #2 You pressed them too firmly into the pan, which condensed them down and made them dense/hard.

Can I add mix-ins like chocolate chips or nuts?

Absolutely! Stir in extras like mini chocolate chips, chopped nuts, candy bars, or sprinkles just after stirring in the last bag of mini marshmallows.

Can I make these ahead of time?

Yes, they are the perfect make-ahead dessert as they stay soft and chewy for days. I store them at room temperature in an airtight container. They will stay good for up to a week, if they last that long!

Should I refrigerate Rice Krispie treats?

No, refrigeration can make them hard and dry. For best texture, store them at room temperature in a sealed air-tight container.

Instructions 

  • Grease a 9×13-inch casserole pan with butter, set aside.
  • In a large, light colored, heavy bottomed pot (like an enameled dutch oven)ย melt butter over medium heat.
  • Cook butter, stirring every few seconds, until butter turns a deep golden color and you see dark flecks. This whole process will take between 8 to 10 minutes if your heat is on medium. (If it's your first time, check out my how to brown butter post for help!)
  • As soon as butter is browned, immediately add 2 bags of the marshmallows and stir until marshmallows are melted and mixture is completely melted and smooth.
  • Remove from heat, then immediately stir inย vanilla extract and salt. Fold in crispy rice cereal, moving quickly and then fold in remaining bag of mini marshmallows.
  • Pour mixture into prepared pan. Using a buttered spatula, lightly press them into pan. Do not press them down too much, just spread them out. (If you press them down too much they will become very dense and not as fluffy.)
  • Allow treats to rest for at least 1 hour at room temperature too cool. Slice into squares or cut into shapes and store any leftovers in an airtight container for up to a week.
