Every spring break, no matter where we were—or weren't—these Rice Krispies Squares made an appearance. Whether we were road-tripping, visiting grandparents, or just staying in pajamas for three days straight, a batch of these gooey, buttery squares meant it was officially break time.

This isn't the slap-it-together version you get from the back of the cereal box. This is the perfected recipe. A touch of brown butter gives it depth. A pinch of salt brings everything into balance. And if you're like me and love those gooey pockets of marshmallow, there's an optional step just for that. I always make a double batch.

Ingredients

Servings:
12
  • 1/4 cup (4 tablespoons/57g) butter (plus extra for greasing pan)
  • 4 cups miniature marshmallows, white
  • 1/2 teaspoon vanilla extract (optional, for flavour)
  • A pinch of salt (optional, balances sweetness)
  • 5 cups crispy rice cereal (e.g., Rice Krispies)
  • *Extra 1 cup mini marshmallows, optional (to fold in at the end for gooey pockets)*

Instructions

  1. 1

    Line a 9×13 inch (23×33 cm) pan with foil or wax paper and lightly butter it. Set aside.

  2. 2

    In a large saucepan, melt the butter over low heat. (For deeper flavour, let the butter cook a bit longer until it turns golden brown and smells nutty, then remove from heat briefly to avoid burning.)

  3. 3

    Stir in the 4 cups (960 ml) of mini marshmallows. Cook over low heat, stirring constantly, until the marshmallows are fully melted and blended with the butter. Remove from heat.

  4. 4

    Stir in the vanilla extract and salt into the melted marshmallow mixture.

  5. 5

    Pour in the rice cereal. Using a wooden spoon or spatula, stir until the cereal is evenly coated in the marshmallow mixture. Work fairly quickly before the mixture cools and stiffens.

  6. 6

    If you want extra gooey bits, fold in the additional 1 cup (240 ml) of mini marshmallows off the heat. Do not stir too much – you want streaks of partially melted marshmallow in the mix.

  7. 7

    Transfer the mixture to the prepared pan. Using a buttered spatula or a piece of waxed paper, press the cereal mixture firmly and evenly into the pan. (Be gentle – you don't want to crush the cereal.)

  8. 8

    Let the pan cool at room temperature until the treats firm up (about 30 minutes to 1 hour). Then lift the block out by the foil or wax paper, place on a cutting board, and cut into squares (about 2-inch (5 cm) squares is standard). Serve and enjoy!

FAQ

Can you make Rice Krispies squares ahead of time?+
Yes! Store them in an airtight container at room temperature for up to 5 days, or wrap them individually and freeze for up to 3 weeks—just thaw for 30 minutes before serving. They're perfect for making a day or two before your spring break party.
What can I substitute if I don't have mini marshmallows?+
You can use regular-sized marshmallows (about 3 cups) and chop them into smaller pieces, or swap in marshmallow fluff (use about 2 cups)—both work great and melt just as smoothly into the cereal.
Why are my Rice Krispies squares too sticky or hard to cut?+
Sticky squares usually mean the marshmallow mixture was too warm when you pressed it into the pan—let it cool for 5-10 minutes first. If they're too hard, you melted the marshmallows too long; aim for just 1-2 minutes of stirring until fully combined.
How do I get those gooey marshmallow pockets throughout the squares?+
Fold in the optional extra cup of mini marshmallows at the very end, after removing the pan from heat—they'll stay chunky and create pockets of extra gooeyness instead of melting completely into the mixture.
