Ingredients:
- 5 tablespoons butter
- 1/4 teaspoon vanilla extract
- 10 cups mini marshmallows, divided (8 cups for melting, 2 cups reserved for texture)
- 6 cups cinnamon sugar flavored Rice Krispies cereal
- 1/2 teaspoon fine grain sea salt
- 1/2 can dulce de leche
Preparing Your Workspace and Ingredients
Before we dive into the gooey, delicious magic of these Brown Butter Dulce de Leche Rice Krispie Treats, let’s get everything prepped. This is key to a smooth and stress-free baking experience. First, grab a large mixing bowl. It needs to be big enough to comfortably hold all those glorious cereal puffs without making a mess. Next, take an 8×8 or 9×13 inch baking pan and generously grease it. You can use butter, non-stick cooking spray, or even line it with parchment paper for extra insurance against sticking. If you use parchment, leaving a slight overhang on the sides will make it incredibly easy to lift the treats out later. Now, let’s talk about the marshmallows. We’re going to use a total of 10 cups of mini marshmallows, but we need them divided. Measure out 8 cups for melting and set aside the remaining 2 cups. These reserved marshmallows are our secret weapon for adding delightful pockets of chewy goodness throughout the treats. Lastly, have your cinnamon sugar flavored Rice Krispies cereal ready to go, and measure out your sea salt.
The Art of Browning Butter
This is where the “brown butter” in our Brown Butter Dulce de Leche Rice Krispie Treats truly shines, imparting a rich, nutty depth of flavor that regular butter just can’t achieve. Place your 5 tablespoons of butter into a medium saucepan. Heat the butter over medium heat. You’ll see it melt and then start to foam. Continue to cook, swirling the pan occasionally, as tiny brown bits begin to form at the bottom of the pan and the butter will start to smell wonderfully nutty. This process typically takes about 5-8 minutes. Keep a close eye on it; you want golden brown bits, not burnt black ones. Once it reaches a beautiful amber color and that distinct toasty aroma fills your kitchen, immediately remove the pan from the heat. This step is crucial to stop the browning process. You can then carefully pour the browned butter into your prepared large mixing bowl, making sure to scrape in all those flavorful brown bits.
Melting the Marshmallow Base
With your warm, fragrant brown butter waiting in the mixing bowl, it’s time to create the sticky, sweet binder for our treats. Add the 8 cups of mini marshmallows to the saucepan you used for browning the butter. Place the saucepan back over low heat. Stir the marshmallows constantly as they begin to melt. They will soften and become smooth and glossy. Once the marshmallows are almost completely melted, add the 1/4 teaspoon of vanilla extract and the 1/2 teaspoon of fine grain sea salt to the saucepan. Stir them in until fully incorporated into the molten marshmallow mixture. The vanilla adds a lovely subtle sweetness, and the salt is essential for balancing the overall richness and enhancing all the other flavors.
Introducing the Dulce de Leche and Cereal
Now for the star of the show, the dulce de leche! Carefully spoon 1/2 can of dulce de leche into the melted marshmallow mixture in the saucepan. Stir vigorously until the dulce de leche is completely blended into the marshmallows, creating a beautiful, marbled effect. This might take a minute or two, but persistence pays off as it will form a luscious, caramel-colored base. Once you have a smooth, homogenous mixture, immediately pour this hot marshmallow-dulce de leche concoction into the large mixing bowl containing your browned butter. Add the 6 cups of cinnamon sugar flavored Rice Krispies cereal to the bowl with the melted mixture. Stir everything together gently but thoroughly with a sturdy spatula or wooden spoon. You want to ensure that every single piece of cereal is coated in the gooey, flavorful marshmallow mixture. This is also the moment to fold in the reserved 2 cups of whole mini marshmallows. Gently mix them in. These whole marshmallows will create delightful pockets of gooey, un-melted marshmallow throughout the finished treats, adding an extra layer of texture and chewiness.
Pressing and Setting Your Masterpieces
Once everything is well combined and coated, quickly but carefully transfer the mixture to your prepared baking pan. This is where your greased or parchment-lined pan comes in handy. Use a greased spatula or your hands (lightly greased, of course!) to gently press the mixture evenly into the pan. Don’t press too hard, or your treats might become dense and tough. The goal is to create a relatively uniform layer. You can even dampen your hands with a little water or lightly grease them to prevent sticking while pressing. Allow the treats to set at room temperature for at least 30 minutes, or until they are firm to the touch. Resist the urge to cut into them too early; they need this time to firm up properly. Once set, you can lift the entire slab out of the pan using the parchment paper overhang, if you used it, and then slice them into your desired bar sizes using a sharp knife. Enjoy these intensely flavored, wonderfully chewy Brown Butter Dulce de Leche Rice Krispie Treats!

Frequently Asked Questions:
Can I make these treats ahead of time?
Absolutely! These treats are best enjoyed within 1-2 days of making them. Store them in an airtight container at room temperature to maintain their chewy texture. Avoid refrigerating, as this can make them too hard.
What is the best way to brown butter?
The key is patience and constant attention. Melt your butter over medium heat in a light-colored saucepan. Swirl the pan occasionally. You’ll see foam form, and then eventually, tiny brown bits will appear at the bottom. It will smell wonderfully nutty. Remove from heat immediately once it reaches a golden brown color to prevent burning.
