Ingredients

0/8 ready
  • 1/2 cup used coffee grounds, dried
  • 8 ounces dark chocolate, chopped
  • 1/2 cup heavy cream
  • 2 tablespoons butter
  • 1 tablespoon whiskey
  • 1/4 cup cocoa powder
  • 1/4 cup finely ground unused coffee
  • Flaky sea salt

The Story & Steps

Every day, millions of coffee grounds get tossed in the trash, their usefulness supposedly exhausted. But those grounds still hold flavor, texture, and the soul of your morning ritual.

The Process

  1. Spread your used coffee grounds on a baking sheet and dry them in a 200°F oven for 20 minutes. Let cool, then pulse briefly in a food processor until fine.
  2. Heat the cream until it just begins to simmer, then pour over the chopped chocolate. Let sit for 2 minutes.
  3. Stir until smooth, then mix in butter, whiskey, and 2 tablespoons of your dried coffee grounds.
  4. Refrigerate for 2 hours until firm enough to scoop.
  5. Roll into balls, then roll half in cocoa powder and half in a mixture of unused ground coffee and sea salt.

The used grounds add an earthy complexity that fresh coffee can't match—they've already given their brightness to your morning cup, leaving behind only the deep, mysterious notes. These truffles taste like midnight and second chances.
