Coffee Assembly

  • Combine instant coffee and sweetener with hot water in a mug or heat-safe container. Stir well until completely dissolved.
  • Add the unsalted butter to the hot coffee and stir until fully melted and incorporated.
  • Fill a tall glass with ice. Pour the hot buttered coffee carefully over the ice to cool it quickly.
  • Add the sugar-free cold coffee creamer and stir to combine. Taste and adjust sweetness if desired.

Topping Preparation

  • Whip the heavy cream with the granulated sweetener and sugar-free flavored syrup until soft peaks form.
  • Spoon or pipe the whipped topping onto the iced coffee just before serving.

Notes

  • Use high-quality instant coffee or substitute strong brewed coffee for richer flavor.
  • Adjust sweetness to taste with your preferred keto-friendly sweetener.
  • For a blended version, combine all ingredients with ice in a blender until smooth.
