What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, but the key is picking the right butter and sea salt for maximum flavor.

• Unsalted butter (1/2 cup / 115g, browned for that rich, nutty flavor)
• Mini marshmallows (4 cups / about 200g, soft and melt easily; I prefer Jet-Puffed for consistency)
• Rice Krispies cereal (6 cups / 150g, classic crispy texture; you can use any puffed rice cereal)
• Sea salt flakes (1 teaspoon, sprinkled on top to balance sweetness; Maldon or fleur de sel works beautifully)
• Vanilla extract (1 teaspoon, optional but adds depth)

If you want to experiment, you can swap the marshmallows for a vegan brand, or use gluten-free puffed rice cereal to make this treat allergy-friendly. The sea salt is what really wakes up the flavor, so don’t skip it or use table salt—it won’t have the same effect.

Equipment Needed

• Large, heavy-bottomed saucepan (essential for browning butter evenly without burning)
• Wooden spoon or heat-resistant spatula (for stirring the marshmallows and cereal)
• 9×13 inch baking dish (or any similar size pan lined with parchment paper for easy removal)
• Measuring cups and spoons (precision helps with texture and salt balance)
• Optional: candy thermometer (if you want to monitor butter temperature precisely, but I usually go by smell and color)

I’ve tried browning butter in thinner pans, but it’s trickier to control the heat. A sturdy saucepan makes all the difference. If you don’t have parchment paper, lightly grease your pan to avoid sticking. A silicone spatula with a flat edge is my personal favorite for folding in the cereal without crushing it.

Preparation Method

1. Brown the Butter: Place 1/2 cup (115g) unsalted butter in a large saucepan over medium heat. Stir frequently as the butter melts, then starts to foam. Keep stirring as the butter changes color to a golden brown and smells nutty, about 4-6 minutes. Watch closely so it doesn’t burn—the color should be a warm amber. Remove from heat immediately when it reaches this stage.
2. Add Marshmallows: Quickly add 4 cups (about 200g) mini marshmallows to the browned butter. Stir with a wooden spoon until the marshmallows are fully melted and smooth, about 2-3 minutes. If using vanilla extract, stir in 1 teaspoon now.
3. Combine with Cereal: Pour 6 cups (150g) Rice Krispies cereal into the marshmallow mixture. Gently fold with a spatula until the cereal is evenly coated. Don’t overmix or you’ll crush the cereal and lose that signature crunch.
4. Press into Pan: Immediately transfer the mixture to a 9×13 inch baking dish lined with parchment paper. Use a buttered spatula or wax paper to press the mixture evenly and firmly into the pan. This helps the treats set with a nice compact texture.
5. Sprinkle Sea Salt: While the treats are still warm, sprinkle about 1 teaspoon of flaky sea salt evenly over the top. The salt adds a wonderful contrast to the sweet, buttery flavor.
6. Cool and Cut: Let the treats cool completely at room temperature for at least 30 minutes to set. Once firm, lift out using the parchment paper and cut into squares or rectangles with a sharp knife.

If the mixture starts to harden before you finish pressing it into the pan, quickly wet your spatula or hands with cold water to smooth it without sticking. The smell of browned butter while mixing is honestly the best part—it signals you’re about to have something special.

Cooking Tips & Techniques

Browning butter can feel intimidating, but the key is patience and close attention. Keep the heat medium or medium-low, and stir often so the milk solids cook evenly without burning. If you see black specks, that’s burnt and you should start over. But when you get it right, the scent alone is worth the extra care.

Use mini marshmallows rather than large ones; they melt faster and blend more smoothly. If you only have large marshmallows, chop them into smaller pieces before adding.

Pressing the mixture firmly into the pan helps your treats hold together better and gives that perfect chewy texture. I’ve found that using parchment paper with a buttered spatula prevents sticking without squishing the treats too much.

Timing is important—work quickly when mixing the cereal with the marshmallow mixture because it cools and hardens fast. Have your pan ready beforehand and sprinkle the sea salt as soon as you spread the mixture to lock in that lovely flavor contrast.

Variations & Adaptations

• Chocolate Drizzle: Melt some dark or milk chocolate and drizzle over the cooled treats. It pairs beautifully with the brown butter flavor.
• Nutty Twist: Add 1/2 cup chopped toasted pecans or almonds to the cereal mixture for extra crunch and depth.
• Vegan Version: Use vegan butter and marshmallows, and check that your puffed rice cereal is vegan-friendly. The technique stays the same.
• Seasonal Flavors: Stir in 1/2 teaspoon pumpkin pie spice or cinnamon with the marshmallows for a cozy fall vibe.
• Salt Variations: Swap sea salt flakes for smoked salt to add a subtle smoky note that’s surprisingly addictive.

One time, I added a handful of dried cranberries for a tart contrast—unexpected but quite nice! Don’t be afraid to experiment a little; this recipe is forgiving and flexible.

Serving & Storage Suggestions

These treats are best served at room temperature so the texture is soft and chewy with a slight crisp from the cereal. They’re perfect on their own or paired with a glass of cold milk or a hot cup of coffee.

Store any leftovers in an airtight container at room temperature for up to 3 days. They’ll stay chewy, but avoid the fridge as they can dry out. For longer storage, wrap individual treats tightly and freeze for up to 2 months. Thaw at room temperature before serving.

Flavors actually deepen a bit after resting overnight—the brown butter taste becomes more pronounced, and the sea salt adds a subtle pop. Just keep the container sealed well to prevent them from picking up other fridge odors.
