Refined-Sugar-Free Blackberry Jam

Recipe by Vegan Recipes and Vibes (@veganrecipesandvibes)

Refined-Sugar-Free Blackberry Jam

Yield: 1 cup | Prep time: 5 minutes | Cook time: 20 minutes | Total time: 2 hours


I made homemade jam for the first time and it turned out so awesome!! It was much easier than I expected and tasted so much better than the jarred stuff. Also quick note: if your berries are rip and sweet enough, leave out the sweeteners to make this 100% added-sugar-free. Enjoy!


  • 2 cups of fresh blackberries (if using frozen, thaw completely)

  • 1 tbsp pure maple syrup (optional)

  • 1 tbsp pure agave nectar (optional)

  • 1 tbsp ground chia & flax meal (or 1/2 tbsp chia seeds + 1/2 tbsp ground flax)

  • A tiny squirt of fresh lemon juice


  • Place a metal spoon in the freezer (you'll need this later).

  • Rinse your fresh blackberries, then place them all into a sauce pot. ○ If you're using frozen then frozen/thawed berries, no need to rinse them. ○ If you want a super smooth, non-chunky jam, place the berries in a food processor and liquify first, then pour berries into the sauce pot.

  • Bring to a boil, then reduce the heat to the lowest setting possible.

  • Use a fork, potato masher, or spatula to smush the berries until you get to the desired chunkiness.

  • Simmer for about 15-20 minutes, stirring occasionally to make sure the bottom doesn't burn.

  • Now do the spoon test. Using your frozen spoon, scoop a little jam out of the pot. If it immediately falls off the spoon in a liquid form, continue simmering on low for a few more minutes. When the jam falls off the spoon in big gloopy chunks, your jam is ready.

  • Turn off the heat and stir in your chia and flax. ○ If the consistency is still too thin and runny, simply add more chia and flax (1/2 tbsp at a time) until you get to the desired thickness. It will thicken as it cools so don't over-do it. You can always add more when it's cooled too.

  • Carefully transfer the jam to a mason jar or glass.

  • Let it sit out until it's room-temp, then place it in the fridge to chill.

  • Store in an air-tight container in the fridge for up to 1 week.


Tips and Tricks:

  • If your berries are ripe and sweet enough, leave the sweeteners out to make this recipe completely added-sugar-free!

  • If you don't have agave nectar, simply use 2 tbsp of maple syrup instead.

  • If you don't have maple syrup, simply use 2 tbsp of agave nectar instead.

  • You can also substitute with 1 tbsp of stevia, xylitol, erythritol, or any other sugar-free sweetener of your choice. Please be aware that if you use granulated or brown sugar, this recipe is no longer refined-sugar-free.

  • You can play around with the berry combinations here. Try a blend of strawberries and blackberries, raspberries, or apricots!
