Butter Rice Krispie treats are often associated with school lunches and bake sales, but this version transforms the nostalgic treat into a gourmet indulgence. By browning the butter and adding a pinch of sea salt, this simple dessert gains layers of nutty, caramel-like flavor and a beautiful balance of sweet and savory.
This recipe holds a special place in my heart—it’s the kind of treat my Nonna would make for Sunday gatherings, always with a twist to keep us guessing. And this twist? It’s downright divine.
Why This Recipe is a Must-Try
It’s easy to overlook Rice Krispie treats as “just cereal and marshmallows,” but with a few upgrades, they become bakery-worthy. Browned butter (or beurre noisette) infuses deep richness, while flaky sea salt adds a satisfying crunch that brings every bite to life.

🍯 A Sweet Memory Reimagined
There’s something inherently comforting about Rice Krispie treats—they evoke childhood joy with every bite. But the beauty of this recipe lies in how it honors tradition while adding an adult-friendly twist. I remember watching my Nonna in the kitchen, effortlessly turning basic pantry ingredients into magic. She didn’t just cook; she transformed. This recipe does the same—it transforms the familiar into the unforgettable.
When I first experimented with browned butter in this treat, I wasn’t prepared for the difference it made. That deep, nutty flavor paired with the sticky sweetness of marshmallows created something I couldn’t stop nibbling on. And the sea salt? That’s the kicker. Just a sprinkle turns a sweet bar into a culinary conversation starter.
These bars have since become a staple at our family gatherings, nestled between trays of Chewy Andes Mint Chocolate Cookies and Coconut Macaroons. They’re often the first to disappear, with guests asking, “What’s in these that makes them taste so good?”

👩🍳 How to Make Salted Brown Butter Rice Krispie Treats
1. Prep the Pan
Line an 8×8 or 9×13-inch pan with parchment or plastic wrap, leaving an overhang. Lightly grease the surface to prevent sticking.
2. Brown the Butter
In a large saucepan, melt the butter over medium heat. Stir constantly as it foams and starts to turn amber with a nutty aroma—this takes about 5–7 minutes. Remove from heat immediately once browned.

3. Melt the Marshmallows
Quickly stir in the mini marshmallows. Mix until fully melted and smooth. If needed, return the pot to low heat for a minute or two.
4. Mix with Cereal
Add the Rice Krispies and sea salt. Stir thoroughly until every puffed grain is coated in gooey, golden sweetness.
5. Press and Set
Transfer the mixture into your pan. Press down evenly with a spatula or wax paper. Chill in the fridge for 10–15 minutes until firm.
Once set, lift from the pan and slice into squares.
