  1. Vanilla: A classic flavor that goes well with everything. Use a tablespoon of pure vanilla extract for a rich, comforting aroma and taste.
  2. Cinnamon: Great for spicing things up. Add two cinnamon sticks to the syrup while it's cooking and remove before storing.
  3. Mint: For a refreshing twist, add a handful of fresh mint leaves to the syrup mix. This works exceptionally well with iced coffee drinks.
  4. Hazelnut: Use hazelnut extract to create a syrup with a rich, nutty flavor. A perfect complement to your morning brew.
  5. Caramel: With a few drops of caramel extract, you can recreate the luxurious taste of caramel syrup, without any added sugar.
  6. Maple: Ideal for those who love the taste of a sweet breakfast. Add a teaspoon of maple extract for a comforting, familiar flavor.
  7. Coconut: If you're a fan of tropical tastes, try using coconut extract. This flavor pairs exceptionally well with cold drinks and coconut milk-based coffees.
  8. Mocha: Coffee with a hint of chocolate? Yes, please! Add unsweetened cocoa powder to the mix for a subtle chocolatey note.
  9. Almond: Almond extract can lend a delicate, sweet, nutty flavor to your syrup. It's a great addition to both hot and iced coffee drinks.
  10. Pumpkin Spice: Make your own fall-inspired syrup with a blend of spices: cinnamon, ginger, nutmeg, and cloves. Perfect for those cozy autumn mornings.

Remember, when you're experimenting with these flavors, start small with the additives. You can always increase the amount according to your taste preference, but it's tricky to balance the flavor if you've added too much from the start. Enjoy exploring these different flavors in your homemade keto coffee syrup!

  3. Sweetener Choices: While the recipe recommends a blend of monk fruit sweetener and half allulose, don't be afraid to try other keto sweeteners. Monk fruit extract or a liquid sweetener might suit your taste better. Remember, sweetness levels may vary depending on your choice of sweetener, so adjust accordingly.
  4. Natural Sweeteners: If you prefer to avoid sugar alcohols, consider natural sweeteners like stevia or erythritol. They're excellent sugar substitutes, keeping your syrup keto-friendly and delicious.
