What I love about this syrup is that it’s all about the flavor of the berries, with no processed sugar. You only need fresh, ripe blackberries, a touch of agave nectar and a little water. It’s just the thing to drizzle over pancakes, stir into smoothies or star in refreshing Blackberry Margaritas.

Ingredients for Blackberry Syrup

- Blackberries: Look for plump, deeply colored fresh blackberries without mold or soft spots. If you’re using frozen berries, thaw them first.
- Agave Nectar: You can use either light or dark agave nectar. Light agave has a mild, almost neutral flavor, while dark agave has a more pronounced caramel flavor.
- Water: Filtered water if possible.
How to Make Blackberry Syrup
Blend blackberries, agave nectar, and water until smooth. Strain into a container, pressing to get all the juice. Cover and refrigerate; use within a week.




Pro Tips
- Use a fine mesh strainer to be sure that the seeds and solids are removed, giving you a smoother syrup.
- If you find the syrup too thin, reduce the amount of water in your next batch or add more blackberries to make it thicker.
- Remember to shake or stir the syrup every time you use it, especially if it has been sitting in the refrigerator for a day or two.
Recipe Variations
- Instead of agave nectar, you can use honey or maple syrup.
- If blackberries aren’t your favorite, raspberries or blueberries make excellent substitutions. Or use a mix of berries!
- For some citrus zing, add a teaspoon of lemon or lime zest to the blender.
- Mix in a splash of vanilla extract for added complexity.
- Stir in a pinch of cinnamon or nutmeg for a warm, spiced flavor.
How to Store
Store the syrup refrigerated in a clean glass jar (ideally sterilized) with a tight seal. Enjoy it within 1 week.

I want mine with pancakes, please. I love blackberries, and too often I pass them up for strawberries. I’ll keep this recipe in mind for when I see them next. 🙂 ~Valentina
That’s wonderful to hear, Valentina!
Blackberries are my favorite berry, so of course I would be all over this blackberry syrup! A drizzle of this over a good vanilla ice cream would be an awesome dessert.
I love how you think, David! This would be amazing on vanilla ice cream.
