📝 About This Recipe

Elevate a childhood classic using the precise, gentle heat of the Instant Pot to create the most decadent Rice Crispy treats you've ever tasted. By utilizing the 'Sauté' function, we achieve a perfect amber brown butter and a flawlessly smooth marshmallow melt without the risk of scorching on a traditional stovetop. Infused with aromatic vanilla bean and finished with a whisper of flaky sea salt, these treats are exceptionally soft, gooey, and sophisticated.

🥗 Ingredients

The Butter Base

  • 3/4 cup Unsalted European-style butter (high fat content preferred for richness)
  • 1/2 teaspoon Fine sea salt (to balance the sweetness)

The Marshmallow Matrix

  • 20 ounces Mini marshmallows (divided; use fresh, soft marshmallows)
  • 2 teaspoons Pure vanilla bean paste (or vanilla extract)
  • 1 tablespoon Whole milk or heavy cream (adds to the creamy texture)

The Crunch and Finish

  • 9 cups Crisped rice cereal (toasted for extra flavor if desired)
  • 1 pinch Maldon flaky sea salt (for topping)
  • 1 tablespoon Cooking spray or extra butter (for greasing the pan and spatula)

👨‍🍳 Instructions

  1. 1

    Prepare a 9x13 inch baking pan by lightly greasing it with butter or lining it with parchment paper, leaving an overhang on the sides for easy removal.

  2. 2

    Plug in your Instant Pot and select the 'Sauté' function. Adjust the setting to 'Normal' or 'Low' heat.

  3. 3

    Add the 3/4 cup of unsalted butter to the inner pot. Allow it to melt completely, stirring occasionally with a heat-resistant silicone spatula.

  4. 4

    Continue cooking the butter for 3-5 minutes until it begins to foam and turn a golden amber color. Look for tiny brown specks and a nutty aroma. This is the 'Brown Butter' phase.

  5. 5

    Immediately press 'Cancel' on the Instant Pot. The residual heat of the stainless steel liner will be enough to melt the marshmallows without burning them.

  6. 6

    Stir in the fine sea salt and the vanilla bean paste, being careful as the moisture in the vanilla may cause the butter to bubble slightly.

  7. 7

    Add 16 ounces of the mini marshmallows to the pot. Stir constantly until they are about 90% melted into a smooth, glossy cream.

  8. 8

    Stir in the tablespoon of milk or heavy cream. This secret step ensures the treats stay soft for days.

  9. 9

    Add the crisped rice cereal into the pot. Using a large, greased spatula, gently fold the cereal into the marshmallow mixture until every piece is evenly coated.

  10. 10

    Fold in the remaining 4 ounces of mini marshmallows. These will only partially melt, creating delightful 'pockets' of goo in the finished product.

  11. 11

    Transfer the mixture into your prepared baking pan. Do not pack it down tightly; use a light touch to spread it to the edges. Pressing too hard results in a tough, hard treat.

  12. 12

    Sprinkle the Maldon flaky sea salt evenly over the top while the mixture is still tacky.

  13. 13

    Allow the treats to cool at room temperature for at least 30-45 minutes. Do not refrigerate, as this can make them brittle.

  14. 14

    Lift the treats out using the parchment paper overhang and slice into large squares using a greased sharp knife.

💡 Chef's Tips

Always use fresh marshmallows; stale ones will result in a dry, rubbery texture. Do not skip the browning of the butter—it provides a complex, toffee-like flavor that balances the sugar. Grease your hands with a little butter or oil before pressing the mixture into the pan to prevent sticking. For the softest results, never use the 'High' Sauté setting; gentle heat is the key to a perfect melt. Store leftovers in an airtight container at room temperature with parchment paper between layers.

🍽️ Serving Suggestions

Serve with a cold glass of whole milk or a creamy oat milk latte. Drizzle with melted dark chocolate for an extra layer of indulgence. Pair with fresh strawberries or raspberries to add a bright, acidic contrast. Serve alongside a scoop of salted caramel gelato for a plated dessert experience. Wrap individual squares in cellophane with a ribbon for a sophisticated homemade gift.
