Prepare to fall in love with Brown Butter Dulce de Leche Rice Krispie Treats!
Ingredients:
- 5 tablespoons unsalted butter
- 1/4 teaspoon pure vanilla extract
- 10 cups mini marshmallows, divided (this is important for texture: 8 cups for melting and 2 cups kept whole for a delightful chew)
- 6 cups cinnamon sugar flavored Rice Krispies cereal
- 1/2 teaspoon fine grain sea salt
- 1/2 can dulce de leche (approximately 7 ounces)
Preparation: Getting Started
Before we dive into the magic of transforming these simple ingredients into something extraordinary, let’s get our workspace ready and our ingredients measured out. This prep work is crucial for a smooth and successful cooking process, especially when working with melting marshmallows, which can set up quickly. Line a 9×13 inch baking pan with parchment paper, leaving some overhang on the sides. This overhang will act as handles, making it much easier to lift the finished treats out of the pan once they’ve cooled. Lightly grease the parchment paper with a little butter or cooking spray to prevent sticking. Measure out your Rice Krispies cereal and set it aside in a large bowl. Measure out your mini marshmallows, keeping the 8 cups for melting separate from the 2 cups you’ll add later for texture. Have your dulce de leche and vanilla extract ready to go.
Phase 1: Creating the Brown Butter Base
This is where the flavor really begin extracts to develop! Place the 5 tablespoons of butter in a medium-sized, heavy-bottomed saucepan over medium heat. It’s important to use a heavier pan to prevent the butter from scorching too quickly. Watch the butter closely as it melts. You’ll see it start to foam. Continue to cook, swirling the pan occasionally, until the bgin extracter begins to turn a golden brown color and develops a nutty aroma. This process, known as browning the butter, unlocks a depth of flavor that plain melted butter just can’t provide. You’ll see tiny brown specks form at the bottom of the pan – this is a good thing! Be careful not to let it burn; if it smells acrid or the brown specks turn black, you’ve gone too far, and you’ll need to start over. Once the butter has reached a beautiful amber hue and smells wonderfully toasty, immediately remove the pan from the heat to stop the cooking process.
Phase 2: Melting the Marshmallows and Incorporating Dulce de Leche
With the brown butter still warm in the saucepan (but not on direct heat), add the 8 cups of mini marshmallows. Stir continuously with a heatproof spatula or wooden spoon. The residual heat from the pan and the brown butter will melt the marshmallows. Keep stirring until the mixture is smooth and creamy. Now, it’s time to introduce the star of our show, the dulce de leche. Spoon the 1/2 can of dulce de leche directly into the melted marshmallow mixture. Add the 1/4 teaspoon of vanilla extract and the 1/2 teaspoon of fine grain sea salt at this stage as well. The sea salt is essential for balancing the sweetness of the dulce de leche and marshmallows, and the vanilla extract enhances all the flavors. Continue to stir gently but thoroughly until the dulce de leche is fully incorporated, creating a wonderfully marbled, caramel-hued marshmallow mixture. It should look glossy and rich.
Phase 3: Combining with Cereal and Adding Texture
Once the dulce de leche mixture is smooth and well combined, it’s time to add our cinnamon sugar flavored Rice Krispies cereal. Pour the 6 cups of cereal into the large bowl you prepared earlier. Pour the warm marshmallow and dulce de leche mixture over the cereal. Now, worgin extractg quickly, begin to fold the cereal into the marshmallow mixture using your spatula. You want to coat every single piece of cereal evenly. This is where the remaining 2 cups of whole mini marshmallows come into play. Gently fold these in as you mix. These whole marshmallows will provide delightful pockets of chegrape juicess within the finished treats, adding an extra layer of texture and surprise. Don’t overmix, as this can make the cereal soggy; just mix until everything is coated and the whole marshmallows are distributed throughout.
Phase 4: Pressing and Setting the Treats
Carefully spoon the mixture into your prepared 9×13 inch baking pan. It will be sticky, so using a lightly greased spatula or your hands (lightly greased with butter or cooking spray) is recommended. Gently press the mixture evenly into the pan. Avoid pressing too firmly, as this can result in hard, dense treats. A light and even press is all you need to create a cohesive slab. Ensure the surface is as level as possible for easy cutting later. Once pressed, allow the treats to cool at room temperature for at least 30 minutes, or until they are firm to the touch. You can speed up the cooling process slightly by placing the pan in the refrigerator for about 15-20 minutes, but be careful not to let them get too cold, as this can make them brittle.
Phase 5: Cutting and Enjoying
Once the Brown Butter Dulce de Leche Rice Krispie Treats have set and are firm, it’s time to cut them. Use the parchment paper overhang to lift the entire slab out of the pan and onto a clean cutting board. Using a sharp knife (lightly greased if needed), cut the treats into your desired squares or rectangles. For a truly decadent experience, consider drizzling a little extra dulce de leche over the top before cutting, or even melting some chocolate and drizzling that. These treats are best enjoyed fresh, within a day or two of making them, to maintain their optimal chewy and crispy texture. Store any leftovers in an airtight container at room temperature.

Frequently Asked Questions:
Q: How do I properly brown butter for this recipe?
To brown butter, melt unsalted butter in a light-colored saucepan over medium heat. Swirl the pan occasionally. The butter will foam, then subside. You’ll start to see tiny brown bits at the bottom and smell a nutty aroma. Once it reaches a deep amber color, immediately remove it from the heat to prevent burning. Be watchful, as it can go from browned to burnt very quickly!
Q: Can I substitute dulce de leche with something else?
While dulce de leche provides a unique caramel flavor, you could experiment with sweetened condensed milk that’s been simmered for a longer time to achieve a similar caramelization, or even a high-quality caramel sauce. However, the texture and depth of flavor from authentic dulce de leche are hard to replicate perfectly.
