Ingredients for this Brown Butter Dulce de Leche Rice Krispie Treats
- 6 tablespoons unsalted butter
- 1 (14 oz) can dulce de leche
- 1 (10 oz) bag mini marshmallows
- 6 cups Rice Krispies cereal
- 1/2 teaspoon sea salt (optional, for balance)
- Additional dulce de leche for drizzling (optional)

Step 1: Brown the Butter
In a large pot over medium heat, melt the butter. Continue cooking, swirling the pot often, until the butter foams and turns a deep golden brown with a nutty aroma. This step adds a rich, toasted flavor base to the treats.
Step 2: Add Dulce de Leche and Marshmallows
Lower the heat to medium-low and stir in the can of dulce de leche. Mix well to combine. Add the mini marshmallows and stir until everything is melted and smooth. Be patient and stir constantly to prevent scorching.
Step 3: Fold in the Cereal
Remove the pot from heat and gently fold in the Rice Krispies cereal. Stir until every puff is thoroughly coated with the caramel-marshmallow mixture.
Step 4: Press into Pan
Lightly grease a 9×13-inch pan or line it with parchment paper. Press the mixture into the pan using a greased spatula or clean hands. Don’t press too hard—you want the bars to stay light and chewy.
Step 5: Cool and Slice
Allow the treats to cool at room temperature for about 30 minutes. Once set, slice into squares. Drizzle with extra dulce de leche for a glossy finish if desired.
Frequently Asked Questions
How do I know when the butter is browned properly?
You’ll know it’s ready when it turns golden brown and emits a rich, nutty aroma. Watch closely to avoid burning.
Can I use regular marshmallows instead of mini ones?
Yes, just chop them into smaller pieces to help them melt evenly.
Is dulce de leche the same as caramel?
Not quite. Dulce de leche is made from sweetened milk, while caramel is made from sugar. Dulce de leche is creamier and richer.
What can I use instead of dulce de leche?
You can substitute with thick caramel sauce, but the flavor will be slightly different.
Can I make these treats vegan?
Yes! Use vegan butter, vegan marshmallows, and a plant-based caramel or coconut dulce de leche.
Why are my treats hard instead of chewy?
Pressing too firmly into the pan or overcooking the marshmallow mixture can make them too dense. Handle with care for softer bites.
