It's very helpful to use a flexible heatproof spatula when making these.


  • 1 stick unsalted butter, cut into pieces (4 oz, 8 TB)
  • 1/3 cup sweetened condensed milk (105 g)
  • 1 TB pure vanilla extract
  • 1 tsp fine-grain salt (like table or sea salt)
  • 1 (10-ounce) bag mini marshmallows, plus 1 cup (40 g), divided
  • 6 cups Rice Krispies (170 g)


  1. Butter an 8x8 square pan. Line with parchment or wax paper, leaving an overhang over two opposite sides of the pan.
  2. In a large, deep pot over medium heat, melt the butter, swirling the pot often, until it browns, smells nutty, and begins to sputter, about 5 minutes. Stir in the sweetened condensed milk, vanilla, and salt with a flexible spatula until combined, being sure to scrape up the brown bits at the bottom of the pot. Add in the 10 ounces of marshmallows and stir until completely melted.
  3. Off heat, stir in the Rice Krispies, just until fully combined, then stir in the remaining 1 cup (40 g) of marshmallows.
  4. Transfer to the prepared pan and, with your hands or the back of the spatula, flatten the mixture lightly and evenly.
  5. Let the treats set up on the counter for at least an hour before cutting into 16 pieces.
  6. Keep the treats in an airtight container at room temperature for up to 3 days.


  • A reminder that the entire recipe is assembled in the same pot initially used to brown the butter, so be sure to use a pot large enough to stir all the ingredients together. I use a 6 quart stockpot.
  • Many recipes on the internet (as does this original recipe on Jessie Sheehan's website) call for 1/2 cup sweetened condensed milk. So if you're tempted to use more than 1/3 cup, go for it.
  • Add the sweetened condensed milk to the pan and give a couple quick stirs before adding the vanilla - this prevents the butter from sputtering unnecessarily (think: oil and water don't mix).
  • If using your hands (versus the spatula) to press the mixture into the prepared pan, it helps to first butter your hands to prevent sticking.
  • Pro Tip: Don't pack down the mixture into the pan - just lightly press to keep the treats airy, soft, and gooey.
  • I'm not opposed to topping these treats with flaky sea salt while they cool.
