This brown butter dulce de leche rice krispie treat recipe elevates the classic snack into an indulgent dessert experience with layers of caramelized flavor. The combination of browned butter, gooey marshmallows, and rich dulce de leche creates something truly special that both kids and adults will devour.
I first made these for my daughter's birthday when the oven broke, and they've become our most requested dessert. The look on everyone's face when they discover the caramel center is priceless every single time.
Ingredients
- Butter: The star of the show that gets browned to develop a nutty, complex flavor that elevates these treats beyond the ordinary.
- Vanilla Extract: A small amount enhances all the other flavors without overpowering them.
- Mini Marshmallows: Used both melted and whole for the perfect texture contrast. The unmelted ones create pockets of gooey goodness.
- Cinnamon Sugar Rice Krispies: The hint of cinnamon pairs beautifully with the dulce de leche. Regular Rice Krispies with added cinnamon sugar work perfectly if you can't find the flavored ones.
- Sea Salt: Balances the sweetness and enhances the browned butter flavor.
- Dulce de Leche: Creates a luxurious caramel center that makes these treats truly exceptional. Look for high-quality dulce de leche for the best flavor.
Step-by-Step Instructions
- Prepare Your Pan:
- Line a 9×9-inch pan with parchment or foil and spray thoroughly with non-stick spray. This crucial step ensures your treats will release cleanly and maintain their perfect shape.
- Brown The Butter:
- Place butter in a large pot over medium heat and watch it carefully as it melts, foams, and then develops brown flecks on the bottom. This process takes about 5 minutes and creates a nutty, caramelized flavor that makes these treats exceptional. Remove from heat immediately when you see those brown bits to prevent burning.
- Melt The Marshmallows:
- Add salt and 8 cups of mini marshmallows to the browned butter, stirring constantly until completely melted and smooth. The residual heat should be enough, but you can return to low heat briefly if needed. The mixture should be glossy and completely free of lumps.
- Add Vanilla:
- Stir in the vanilla extract thoroughly to distribute the flavor evenly throughout the marshmallow mixture. This small touch adds incredible depth to the finished treats.
- Combine With Cereal:
- Pour the melted marshmallow mixture over the cereal in a large bowl and fold together until every piece is evenly coated. Work quickly but gently to maintain the cereal's crisp texture.
- Add Whole Marshmallows:
- Fold in the remaining mini marshmallows while the mixture is still warm. This creates pockets of gooey marshmallow throughout the treats for textural contrast.
- Layer With Dulce de Leche:
- Press half the rice krispie mixture into your prepared pan, spread the dulce de leche evenly over this layer, then top with remaining rice krispie mixture. Use a buttered spoon to press the layers together gently without compacting them too firmly.
- Cool And Set:
- Allow the treats to cool completely at room temperature before cutting into squares. This patience is rewarded with perfectly set treats that hold their shape.

The cinnamon sugar cereal version has become my signature potluck contribution. My nephew once ate four squares at a family gathering and still talks about them years later. The slight spice from the cinnamon creates the perfect counterpoint to the sweet dulce de leche.
The Secret To Perfect Texture
The most common mistake with rice krispie treats is pressing them too firmly into the pan. Use gentle pressure with a buttered spoon or your fingers to maintain their delicate, airy structure. Compressing them too much results in dense, hard treats rather than the tender, chewy texture that makes them irresistible. I learned this lesson after making hockey puck treats for a bake sale years ago.
Flavor Variations
The brown butter dulce de leche base makes an excellent canvas for creative variations. Try adding a layer of chocolate ganache on top, sprinkling with flaky sea salt before setting, or incorporating a teaspoon of espresso powder into the marshmallow mixture for a mocha version. My family particularly loves the salted chocolate version for holiday gatherings where they disappear within minutes.
Make Ahead Tips
These treats actually improve with a few hours of rest after assembly, allowing the flavors to meld. For longer storage, cut into squares, wrap individually in wax paper, and place in a freezer safe container. Thaw at room temperature for about 30 minutes before serving. This has saved me countless times when unexpected guests arrive or when I need a quick dessert for impromptu gatherings.
Serving Suggestions
While delicious on their own, these treats create a showstopping dessert when warmed slightly and topped with vanilla ice cream. The contrast of temperatures and textures makes for an elevated dessert experience. For a playful presentation, cut into sticks rather than squares and serve standing in a tall glass like a sweet bouquet at your next gathering.

Brown butter and dulce de leche elevate a classic childhood favorite into an unforgettable dessert. These treats prove that no-bake recipes can still impress!
Frequently Asked Questions
- → How do I know when butter is properly browned?
Butter is properly browned when you see small golden-brown flecks forming at the bottom of the pan. It will have a nutty, toasty aroma. Use a light-colored pan so you can easily monitor the color change, and remove from heat immediately once the flecks appear to prevent burning.
- → Can I use regular Rice Krispies instead of cinnamon sugar flavor?
Yes! If you can't find cinnamon sugar Rice Krispies, simply use regular Rice Krispies and add 1/4 to 1/3 cup of cinnamon sugar to the mixture for a similar flavor profile.
- → Why add some marshmallows after melting the first batch?
Adding some unmelted mini marshmallows at the end creates texture variation with chewy pockets throughout the treats. This technique gives you the perfect balance of gooey binding and distinct marshmallow pieces.
- → What is dulce de leche and can I substitute it?
Dulce de leche is a caramelized milk spread with a rich, sweet flavor. You can substitute with caramel sauce, Nutella, or cookie butter spread, though each will provide a different flavor profile.
- → What's the best way to cut these treats neatly?
For clean cuts, let the treats cool completely. Use a sharp knife dipped in warm water and wiped dry between cuts. You can also spray the knife lightly with cooking spray to prevent sticking.
- → Can I make these ahead for a party?
Absolutely! These treats stay fresh in an airtight container at room temperature for 2-3 days. For longer storage, wrap individual pieces in wax paper and freeze for up to 6 weeks. Thaw at room temperature before serving.
