Found originally at All Day I Dream About Food

Why You'll Love It:

  • Refreshingly light, with zero added sugar

  • Uses simple ingredients you likely have—especially leftover cold brew

  • A low-effort dessert: no churner, just a fork and patience

  • Fully keto-friendly: under 1 g net carb per serving

Ingredients (makes ~6 servings)

  • 3 cups strongly brewed coffee, cooled

  • ½ cup granular sweetener*

  • 1½ tbsp dark rum (optional—helps prevent freezing too hard)

  • ½ cup heavy whipping cream

  • 1½ tbsp powdered sweetener (for whipped cream)

  • ½ tsp vanilla extract

*Best texture with allulose or a blend of allulose + erythritol; use xylitol if needed.

Instructions

  1. Stir the granita base
    Combine coffee, granular sweetener, and rum (if using). Whisk until dissolved.

  2. Freeze then fork-flake
    Pour into a shallow glass or ceramic pan. Freeze until edges begin to ice—about 45 minutes. Scrape with a fork every 30–40 minutes until fluffy and crystal-y.

  3. Make whipped cream topping
    Whip heavy cream, powdered sweetener, and vanilla until soft peaks form.

  4. Serve & enjoy
    Spoon granita into dessert cups. Top with a dollop of whipped cream and a sprinkle of cinnamon, if desired.

Tips for Success

  • Pan choice matters: glass or ceramic speeds freezing. Avoid metal, which can be tough on a fork.

  • Don't forget the timer: scraping while still semi-frozen yields fluffy crystals—wait too long and it becomes a solid block.

  • Sweetener tip: allulose keeps frozen desserts soft. If unavailable, a 50/50 erythritol-allulose or xylitol blend works.

Storage

Keep leftovers in a covered container in the freezer for months. Thaw slightly, scrape with a fork, and you’re good to go.
