What You Need to Make Keto Coffee Syrup

  • Keto sweetener: Replaces regular sugar, providing sweetness without raising blood sugar levels. We recommend monk fruit sweetener, allulose, or erythritol.
  • Water: Combines with the keto sweetener to create a syrup consistency.
  • Xanthan gum or guar gum: Acts as a thickening agent, providing the right texture for the syrup.
  • Optional flavorings: Cinnamon sticks, vanilla extract, or other keto flavoring syrups enhance the taste of the coffee syrup.

How to Make Keto Coffee Syrup

  1. Combine: Mix water and keto sweetener in a small saucepan.
  2. Heat & thicken: Heat the mixture until the sweetener dissolves, add gum, and let it thicken.
  3. Cool & flavor: Allow the syrup to cool and optionally add your desired flavorings.
  4. Store: Pour the cooled syrup into an airtight container for storage. And that’s it! Your homemade keto coffee syrup is ready. Add it to your morning coffee or iced coffee, and even to homemade lemonades and your favorite cocktails.
