Ingredients

Scale

Base Ingredients

  • 1 3/4 cups water
  • 1 cup monk fruit sweetener (Lakanto golden monk fruit recommended)
  • 1 cup canned pumpkin puree (Libby’s works great)
  • 2 tsp pumpkin pie spice blend
  • 1/4 tsp salt

Thickener and Additional Spice

  • 1/8 tsp xanthan gum
  • 1 tsp pumpkin pie spice blend

Finishing

  • 2 tsp pure vanilla extract

Instructions

  1. Combine Base Ingredients and Heat: In a medium saucepan, combine water, monk fruit sweetener, canned pumpkin puree, 2 teaspoons of pumpkin pie spice blend, and salt. Heat over medium heat, stirring frequently for 5-7 minutes until the mixture is smooth and well combined. This helps the sweetener dissolve fully and starts infusing the spices.
  2. Add Thickener and Remaining Spice: Remove the pan from heat. While stirring constantly, sprinkle xanthan gum over the mixture to prevent clumping, ensuring thorough incorporation. Stir in the remaining 1 teaspoon of pumpkin pie spice to build deeper flavor.
  3. Simmer and Develop Flavor: Return the pan to low heat and simmer gently for 10-15 minutes, stirring occasionally. This slow simmer melds the pumpkin and spices beautifully while preventing burning or over-reduction.
  4. Finish with Vanilla and Cool: Remove from heat and stir in vanilla extract. Pour syrup into a heat-safe container and let cool to room temperature. The syrup will thicken further as it cools, perfect for drizzling into coffee or beverages.

Notes

  • Use pure vanilla extract for best flavor.
  • Stir the xanthan gum in gradually to avoid clumping or graininess.
  • Simmer gently to prevent burning and preserve smooth texture.
  • Store syrup in an airtight container in the refrigerator for up to two weeks.
  • Adjust pumpkin pie spice blend quantity to taste or use your preferred blend.
