Ingredients Overview

This recipe is beautifully simple, relying on just a handful of ingredients you likely already have in your pantry. The key player here is the brown butter. By gently cooking unsalted butter until the milk solids turn golden brown, you unlock a warm, complex flavor that infuses every bite. Mini marshmallows provide the sticky sweetness that holds the treats together, while crispy rice cereal gives that beloved light crunch. Vanilla extract adds a hint of warmth, and kosher salt balances the sweetness, ensuring these treats are not overly saccharine but perfectly balanced.

Step-by-Step Instructions

The process of making these brown butter Rice Krispie treats is straightforward, but each step plays a critical role in achieving the perfect texture and flavor.

First, prepare your baking dish by greasing it with a little butter or nonstick spray. This ensures the treats will come out cleanly, leaving you with perfect squares.

Next comes the most important step: browning the butter. Melt the butter in a large pan over medium-low heat. As it melts, the butter will foam and crackle. Continue swirling the pan occasionally to prevent burning, and watch as the color deepens into a golden brown. The aroma will shift from buttery to nutty, signaling that it’s time to add the marshmallows. The key here is patience—don’t rush this process, as the nutty flavor is what makes this recipe stand out.

Once the butter is browned to perfection, reduce the heat and stir in the marshmallows, vanilla, and salt. As the marshmallows melt into the brown butter, the mixture will become creamy and smooth. This is where you need to keep stirring to ensure everything is evenly combined.

Once the marshmallows are fully melted, remove the pan from the heat and fold in the crispy rice cereal. Stir gently but thoroughly to coat every grain in that luscious marshmallow mixture. When transferring to your greased dish, be mindful of how firmly you press the mixture down—press just enough to create an even layer but not so much that you compress the treats too much, which would make them dense instead of chewy.

Let the treats cool for about an hour at room temperature before slicing them into squares.

Recipe Tips

To brown the butter without burning it, keep the heat on medium-low and swirl the pan often. The butter’s color will change from yellow to golden brown, and a nutty aroma will develop—this is your sign that it’s ready.

When pressing the mixture into the baking dish, be gentle. Overpacking can make the treats too dense. You want them chewy, not rock hard.

Adjust the salt according to your preference. If you enjoy a sweet-salty combo, a pinch more salt can enhance the flavor.

For added fun, mix in extras like chocolate chips, sprinkles, or chopped nuts to personalize your treats.

What to Serve With This Recipe

These brown butter Rice Krispie treats are a perfect standalone snack, but pairing them with a glass of cold milk creates a nostalgic, comforting experience.

For parties, consider serving them alongside other treats like brownies or cookies to create a varied and delightful dessert spread.

Frequently Asked Questions

Can I use regular marshmallows instead of mini ones?
Yes, you can use regular-sized marshmallows. Just be sure to adjust the melting time, as larger marshmallows will take a bit longer to break down.

How do I store the Rice Krispie treats to keep them fresh?
Store them in an airtight container at room temperature. Avoid refrigeration, as this can make the treats too hard. They’ll stay fresh for up to 2 days.

Can I make these treats in advance for an event?
Yes! You can make them up to a day in advance. Just be sure to store them properly in an airtight container, and they’ll be just as delicious when served.

What’s the best way to get the mixture into the pan without sticking to my hands?
A simple trick is to lightly dampen your hands with water or butter the back of a spoon to press the mixture down evenly. This prevents sticking and helps shape the treats with ease.

Storage and Shelf Life
Once you’ve made your batch of brown butter Rice Krispie treats, storing them properly ensures they stay fresh and chewy. The best way to store them is in an airtight container at room temperature.

This way, they can last for a few weeks. Simply thaw at room temperature when you’re ready to enjoy them.

Recipe Variations

There are so many ways to elevate this simple treat. For a more decadent version, swirl in peanut butter as you mix the marshmallows. You could also drizzle melted chocolate over the top of the finished squares for an extra touch of indulgence. Nutella is another fantastic option for a richer, chocolate-hazelnut flavor. If you’re feeling adventurous, try mixing in some toasted coconut or crushed pretzels for a fun twist on texture and flavor.

Ingredients

9 cups (225 grams) crispy rice cereal
2 sticks (226 grams) unsalted butter
2 10-ounce bags of mini marshmallows
1 teaspoon vanilla extract
1/2 teaspoon kosher salt

Instructions

Grease a 9×13-inch baking dish with nonstick spray or a little butter to ensure easy removal later.

In a large stainless steel pan, melt the butter over medium-low heat. As the butter heats, it will foam and sizzle. Keep the butter moving by swirling the pan occasionally. When the crackling noise subsides, continue cooking until you notice the butter turning golden brown, releasing a warm, nutty fragrance, and dark amber bits collecting at the bottom of the pan. This process should take around 2 to 3 minutes after the sizzling stops. At this point, reduce the heat to low and stir in the marshmallows, vanilla extract, and kosher salt. Keep stirring until the marshmallows are fully melted and the mixture is smooth.

Once melted, remove the pan from heat and fold in the crispy rice cereal. Stir gently but thoroughly until all the cereal is evenly coated in the marshmallow mixture. Transfer this mixture to your prepared baking dish and gently press it into an even layer using a spatula, wooden spoon, or your damp hands. Be careful not to press too hard—you want the treats to stick together but remain chewy rather than dense.

Let the rice krispie treats cool completely at room temperature, about 1 hour. Once set, slice them into 12 squares. Store them in an airtight container at room temperature for up to 2 days.
