Easy Keto Brown Sugar Pumpkin Spice Syrup

Now we are all aware that coffee truly runs through my veins (thanks to would ever came up with those words). Of course, during the fall months, we are all about the pumpkin spice and everything! So, why not give y’all what you really really want? A delicious Brown Sugar Pumpkin Spice Syrup that will for sure be a part of all your fall coffee adventures.

This 5 ingredient pumpkin syrup is perfect for hot or cold drinks. Use it in all your favorite coffee creations. My favorite way to use is in my pumpkin spice lattes.

Now, this is a low-carb Keto version, but you can absolutely use regular brown sugar if you’re not a Keto babe. For this Keto version, I used brown sugar Swerve. I tried monk fruit, but I found it didn’t melt as well. So the brown sugar swerve is the best sugar substitute for this recipe.

How to make Brown Sugar Pumpkin Spice Syrup:

The best part about this recipe is that it comes together in no time. You only need a few simple ingredients you probably already have on hand. And the rest takes between 5-7 minutes.

  • Simply add the ingredients to a small saucepan over medium heat.
  • Once the sugar melts, let the mixture come to a slow simmer.
  • Remove the syrup from the heat.
  • Let the mixture cool and serve or store away in a jar with an airtight lid.

This recipe makes a little over 1 cup of brown sugar pumpkin spice syrup. Syrup will keep in the fridge for about 2 weeks. Make sure you give your syrup a good shake before every use. For more tips, check out the FAQs below the recipe.

  1. First, heat the water and sweetener in a small saucepan over medium heat. Continuously stir the mixture until the sweetener/sugar dissolves. Add the pumpkin purée, pumpkin pie spice, vanilla extract, and salt to the pan and stir until all the ingredients are combined. Lower the heat and bring the mixture to a slow simmer for ~3 mins or until it begins to thicken, stirring frequently. Remove the mixture from the heat and set aside.
  2. This is NOT mandatory, but you can if you want to. While the syrup is still warm, you can filter it through a fine mesh strainer to ensure no sediments and it's completely smooth. I don’t do this all the time and again, I don't think it's really necessary, but it is an option.
  3. Once the syrup is completely cooled, serve it in your favorite coffee drinks. Store the syrup in a jar and serve when needed. The syrup will keep in the fridge for about 2 weeks.


  • The syrup will thicken as it sits in the fridge. To make the syrup more pourable, you can set the syrup jar in hot water for 5-7 minutes before use.

Hi Charlotte,

I wanted to thank you for this recipe. I rarely ever comment on these things, but this is so perfect that I thought I would reach out. I LOVE all things pumpkin, but I hate buying store bought creamer. For lots of reasons. Other recipes I have tried have not hit that perfect pumpkin-but-not-too-sweet-with-just-the-right-spice note. In a word, this recipe is “cozy.” In three words, “cozy AF.” Thanks again!


YES!!!1 THIS is all I want to hear! Thanks so much for the support my love. you are amazing I am so happy you enjoyed it.

Where did you get your Pumpkin Pie Spice blend label for your dried spice mixture? Darling!

This looks delicious. I may have to give this a whirl. Fancy for fall!
