Why You’ll Love This Recipe
Once you taste one of these brown butter rice krispie treats you will never be able to settle for a regular rice krispie treat again. With just a couple minutes more you can turn a classic treat into something amazing.
Ingredients
- Marshmallows. You can use full size marshmallows or mini marshmallows but I almost always use the mini because I find they melt easier and more evenly. I use an entire 16 oz. bag of marshmallows.
- Rice Krispies. My cereal to marshmallow ratio is different than you will find for the classic rice krispie treat recipe on the cereal box. Using more marshmallow makes for a softer and gooey treat!!
- Brown Butter. Be sure and follow the tutorial here and don’t skip this part, it gives the treats amazing flavor.
- Flaky Salt. Use a good quality salt, not a table salt. This is my favorite French fleur de sel that I use all the time. You can also use a Kosher salt or any flaky sea salt. Half of the salt is added into the marshmallow mixture and the other half is reserved to sprinkle on top.
- Vanilla.
How to Make Brown Butter Rice Krispie Treats
- Melt butter in a heavy bottom pan and stir until it begins to foam and turn golden brown. Stir constantly. It can go from browned to burned very quickly.
- Add marshmallows to brown butter and stir until marshmallows are melted. Use a heavy bottom pan so you don’t burn the mixture. Stir constantly.
- Add the marshmallow mixture into the cereal in a large bowl and stir until the cereal is totally coated.
- Press the mixture into a buttered or parchment lined 9 x 13 pan. If you want a thinner treat, use a larger pan. I like my treats light and airy so I don’t push the cereal mixture down too much, just gently to even it out.
- Sprinkle the remaining salt over the top, while the treats are still warm, then allow the treats to cool and set up before removing from the pan.
- Cut the treats into any size square you like, I like mine big!
The flavor of these are amazing. I love watching someone take a bite and then try to figure out what is different about these treats. They usually guess the salt but have a hard time identifying the brown butter. It is the secret ingredient to some of the best Rice Krispie treats you will ever have!!
Frequently Asked Questions
What is the best way to store Brown Butter Rice Krispie Treats?
To keep them fresh, store them in an airtight container at room temperature. I put a sheet of wax paper or parchment paper between the layers to keep them from sticking together.
They are best eaten within a couple of days, if it is going to be longer than that I recommend freezing them
Can I freeze rice krispie treats?
These treats freeze really well. You can cut them into squares and wrap each square individually in plastic wrap and then put the squares together in an airtight container or ziploc bag.
That way you can easily pull one out at a time and enjoy them.
If you know you are going to be serving all of them at the same time, I will just layer them between pieces of wax paper or parchment paper in an airtight container.
They will keep for up to six months in the freezer. Just let stand at room temperature for 30-40 minutes before serving
What is Brown Butter?
We like to call brown butter liquid gold at our house. It is butter that has been browned in a pan. I have a whole post on how to make brown butter that you can check out for an easy to follow tutorial.

Just made these and they are DELICIOUS! The recipe calls for only 12oz of rice Krispy cereal which I think is a typo? I added 7 cups which seemed to be perfect! Love the brown butter taste!
