Ingredients

  • 1 tablespoon instant espresso powder
  • 1 teaspoon hot water
  • 4 tablespoons unsalted butter (1/2 stick), plus more for coating the pan
  • 1 (10- to 10-1/2-ounce) bag mini marshmallows (about 5 1/2 cups)
  • 1/4 teaspoon fine salt
  • 6 cups puffed rice cereal (about 7 ounces), such as Rice Krispies
  • 8 ounces white chocolate (not chips), coarsely chopped
  • 3 tablespoons heavy cream
  • 2 tablespoons coffee liqueur, such as Kahlua

Method

  • Coat a 13-by-9-inch baking pan with butter and set it aside.
  • Place the espresso powder in a small bowl, add the hot water, and stir until the powder has dissolved; set aside.
  • Melt the measured butter in a large pot or Dutch oven over medium-low heat.
  • Add the marshmallows and salt and cook, stirring frequently, until the marshmallows are completely melted.
  • Add the dissolved espresso powder and stir to combine.
  • Remove the pan from the heat, add the rice cereal, and stir until combined.
  • Transfer the mixture to the prepared baking pan and press it into an even layer with your hands.
  • Set it aside while you make the glaze.
  • Place the chocolate and cream in a small saucepan over low heat and stir until melted and combined (the mixture will not be completely smooth).
  • Remove from the heat, add the coffee liqueur, and whisk until combined and smooth.
  • Pour the mixture over the treats and spread it into an even layer.
  • Let sit until the treats are completely cooled and the chocolate is set, about 30 minutes.
  • Cut the treats into 24 (2-inch) squares.
  • They can be stored in an airtight container at room temperature for up to 1 day.
