How to make Brown Butter Dulce de Leche Rice Krispie Treats
This is a quick, hands-on recipe with a little technique — browning butter — that makes all the difference. Move deliberately while stirring; the aroma is part of the fun, and small adjustments to heat keep the butter toasty rather than bitter.

Ingredients:
- 5 Tablespoons Butter
- ¼ teaspoon Vanilla Extract
- 10 Cups Mini Marshmallows (divided)
- 6 Cups Rice Krispies Cereal (cinnamon sugar flavored, see note)
- ½ teaspoon Sea Salt (fine grain)
- ½ Can Dulce de Leche
Directions:
- Spray a 9×9-inch pan with non-stick spray and line it with a foil or parchment paper sling. Spray again.
- Place a large pot on the stove over medium heat, add your butter and let it melt and then brown. *See notes below for browning butter.
- Once the butter is browned, remove from the heat and add the salt and 8 cups of mini marshmallows. Stir until everything is completely melted and smooth. If you need to put it back on the heat to finish melting the marshmallows, that is fine. You just don’t want the browned butter to burn.
- Once it is smooth, add vanilla and stir again.
- Measure out the rice krispies cereal in a large bowl. Pour the melted marshmallows over the rice krispies and mix well.
- Add in the remaining marshmallows while still warm.
- Lightly press about half of the rice krispies mixture into your prepared pan (see note). Flatten it down so it is even in the pan and then spread the dulce de leche all over the rice krispies in an even layer.
- Top with the rest of the rice krispies mixture and lightly press it around until it is evenly spread into the pan. Let it set at room temperature until cooled.
How to serve Brown Butter Dulce de Leche Rice Krispie Treats
Cut into generous squares and serve at room temperature so the dulce de leche keeps a soft, molten ribbon through the center. For an extra sensory moment, sprinkle flaky sea salt on top of each square just before serving to lift the sweetness and accentuate the brown-butter notes. These are lovely with a strong coffee, spiced tea, or a chilled milk glass.
How to store Brown Butter Dulce de Leche Rice Krispie Treats
Store in an airtight container at room temperature for up to 3 days. If your kitchen is warm, keep them in the fridge for up to a week — bring to room temperature for 10–15 minutes before serving so the dulce de leche softens. For longer storage, wrap individual squares and freeze for up to 2 months; thaw in the fridge overnight.
Tips to make Brown Butter Dulce de Leche Rice Krispie Treats
- Browning butter: Swirl the butter in a light-colored pan over medium heat and watch for nutty brown specks and a toasty aroma; remove immediately to avoid burning.
- Use a silicone spatula to fold cereal and marshmallow — it helps preserve pockets of air for a lighter bar.
- If your dulce de leche is very thick, warm it slightly in the microwave for 10–15 seconds to make spreading easier.
- For neat cuts, dip your knife in hot water and wipe between slices. For another decorative Rice Krispie presentation idea, see this fun turkey-leg treat for event inspiration: creative Rice Krispie turkey-leg dessert.
Variations (if any)
- Chocolate swirl: Thin semisweet chocolate and drizzle over the top before the final set for a mocha-kissed bar.
- Nutty crunch: Stir in 1 cup toasted chopped pecans or hazelnuts for texture.
- Citrus lift: Add a teaspoon of orange zest to the melted marshmallow mixture for a bright counterpoint to the caramel.
- Vegan adaptation: Use vegan marshmallows and dairy-free butter; swap dulce de leche for a thick date caramel.
FAQs
Q: Can I use regular-sized marshmallows instead of mini?
A: Yes — roughly 10 cups of regular marshmallows equals the 10 cups of mini called for. They may take a bit longer to melt, so keep the heat gentle.
Q: What is the best way to brown butter without burning it?
A: Use medium heat in a light pan, swirl rather than stir constantly, and watch for foam to subside and brown specks to appear; remove from heat at the first nutty aroma.
Q: Can I make these gluten-free?
A: Most Rice Krispies are gluten-free, but check the cereal label for cross-contamination. Use certified gluten-free cereal to be safe.
Q: My bars are too sticky — what went wrong?
A: Either too much heat burned some of the sugar, or they haven’t set fully; try pressing slightly thinner in the pan and let them cool completely at room temperature before storing.
Q: How do I reheat frozen bars?
A: Thaw overnight in the fridge, then bring to room temperature for the best texture; a few seconds in the microwave can soften them but may alter the crispness.
