Homemade Blueberry Simple Syrup (for coffee, cocktails & iced teas)
If you’ve been craving a little change in your regular lattes, oh, I’ve got just the thing for you — a homemade blueberry simple syrup that brings a soft, Nordic note to your cup. It’s simple to make, using only a few real ingredients and a gentle simmer, and the result is a sweet, richly flavored syrup that turns any latte into something a little special. And the best part? It’s not just for coffee — this same syrup goes perfectly in iced tea or your favorite cocktail.
I told you in my blueberry iced latte post, how I first thought that if you mix coffee and blueberries, you must be crazy (spoiler alert, it was better than I’ve ever thought it would be!).
That got my mind filled with blueberry lattes and more. But all began with the blueberry hibiscus iced tea and this homemade blueberry syrup, which I originally made for the iced tea.
Why you’ll love this blueberry simple syrup recipe?
Well, this recipe couldn’t be simpler:
- It has only three ingredients.
- You let blueberries simmer, blend, and strain into syrup with sugar.
- The basic blueberry syrup recipe can be tweaked with various add-ons, such as cardamom (which I use in my blueberry coffee recipes) or lemon juice, or lemon peel.

Blueberry simple syrup uses & serving suggestions
One of the things about blueberry simple syrup I personally love is how versatile it is — here are some ways to enjoy it beyond just your morning coffee:
- Blueberry Iced Coffee: Add 1–2 tablespoons of syrup to your cold brew or iced coffee, stir well, and top with milk or a dairy-free alternative for a fruity twist on your cold coffee. Season with cardamom, or vanilla sugar if desired.
Try this: Blueberry iced latte
- Refreshing Blueberry Iced Tea: Mix the flavourful syrup into chilled tea with ice, some elderflower juice, and fresh lemon juice for a naturally vibrant colored iced tea bursting with summer flavors.
Try this: Blueberry hibiscus iced tea
- Cocktail & Mocktail Mixer: Use the rich syrup as a base for blueberry cocktails or mocktails. Mix a few tablespoons of blueberry simple syrup for cocktails in a glass with some club soda and a lime wedge for a simple, fizzy drink.
- Homemade Blueberry Lemonade: Mix simple syrup with a lemon or lime lemonade, add ice cubes, and garnish with a few high-bush blueberries on a cocktail stick and a reusable metallic straw.
- Breakfast Treats: Let the pot simmer longer for a thicker syrup. Drizzle your blueberry syrup over pancakes, French toast, waffles, or yogurt for a burst of fresh blueberry sweetness.
- Dessert Topping: Warm the syrup slightly and pour it over vanilla ice cream or cheesecake for a simple but elegant dessert sauce.

How to make blueberry syrup from scratch
Step one: prep the ingredients
Pour blueberries and water into a saucepan and bring to a boil.
Step two: Simmer the blueberries
Let blueberries cook with water for 2 minutes, and blend them with an immersion blender or cool and blend with a smoothie blender. If you prefer clear, simple syrup, strain the blueberries, save the liquid, and discard the blueberry mush, or use it in your morning yoghurt with granola.
Step three: Measure blueberry juice and sugar
Measure the blueberry juice and return it to the pot. To make simple syrup, you need one part juice and one part sugar.
You should have now about 100 ml of blueberry juice, so you can add the 100 ml of sugar (90 grams) into the saucepan. If you have more, just add an equal amount of sugar in volume measurements compared to the blueberry liquid you have. Let it simmer until the sugar dissolves.
Step four: Store and let it cool
Store air tightly in a clean glass bottle. Set aside to cool down.
You now have blueberry simple syrup for about 3-5 coffee or iced tea portions, so you can store it for later use too!
Storage & Shelf Life
Store in an airtight container in the fridge for 1–2 weeks. I love to use these 250ml glass bottles with the flip cork, just the perfect size for the simple syrup!
If you’d like to make a bigger batch at once, you can freeze the homemade blueberry simple syrup in a freezer-safe container for up to a year. Ice cube trays work perfectly — especially ones that hold about a teaspoon each — so you’ll always have ready-to-use portions on hand. When frozen just knock the blueberry syrup cubes out and store in a freezer bag for next blueberry syrup emergency!
Tips & Flavor Boosters: How to tweak this recipe
Making a homemade blueberry coffee syrup is kinda simple, but these little tips can take your syrup to the next level with richer flavor and better balance:
- Store properly: Your syrup will keep well in the fridge for up to two weeks. For longer storage, freeze it in small portions or ice cube trays for easy use later.
- Add a pinch of salt: A tiny pinch of salt in the syrup can enhance the sweetness and round out any bitterness, making your syrup taste more balanced and full-bodied.
- Use lemon juice for brightness: Adding a bit of fresh lemon juice not only helps preserve the syrup but also adds a fresh, tangy note that brightens the blueberry flavor.
- Macerate the berries first: Try mixing fresh or frozen blueberries with sugar and a splash of lemon juice, and let them sit at room temperature for 30–60 minutes before cooking. This helps the sugar draw out the natural juices and intensifies the blueberry flavor.
