Why We Love This Recipe

  • Quick and easy recipe: This recipe is as simple as boil, mash, cool, and store. It's as easy as making regular simple syrup, but it's packed with extra delicious flavor from fresh blackberries. It's way better than store bought and so versatile.
  • Stores well: You can keep this simple syrup in a mason jar/sealed container in the refrigerator, or freeze it in an ice cube tray. This recipe yields 14 fluid ounces of syrup, so one batch will last you several weeks or even months (unless you're like us and use it in pretty much every summer recipe).
  • Versatile: This simple syrup packs a fruity and tart punch of blackberries to cocktails, baked goods, cold and hot drinks, marinades/dressings and more.
  • Enjoy summer flavors all year long: If you freeze this blackberry simple syrup, you can enjoy all year, even when blackberries aren't in season!

Ingredients

Here's what you'll need to make this blackberry simple syrup:

Fresh blackberries with sugar, brown sugar, water, and ingredients for blackberry jam preparation.
You only need 4 ingredients (including water) to make this super easy simple syrup!

Ingredient Notes

  • Sugar: We're using both granulated white sugar and brown sugar in this simple syrup.
    • White sugar dissolves very quickly and is traditional in making any simple syrup.
    • Brown sugar adds deeper flavor to this simple syrup. The syrup develops a caramel-like flavor that pairs perfectly with the tart berries. If you prefer, you can just use one or the other (white or brown sugar).
  • Blackberries: We prefer using fresh, but frozen works, too!
  • The only other ingredient you need to make this simple syrup is water. It's that easy!

Instructions

(1) Add the water, sugar, and blackberries to a small saucepan over high heat. Stir until the sugar dissolves and bring to a boil.

Left: adding all the ingredients to a saucepan. Right: mixing and heating the simple syrup.
Add everything to a saucepan and bring to a simmer.

(2) Once it starts to boil, reduce the heat to medium and simmer for 5 minutes. Use a masher, the back of a fork or a muddler to mash the berries thoroughly. Remove from heat and let sit for 15 minutes. 

(3) Strain the syrup through a fine mesh sieve, using a spoon or spatula to push as much liquid through the sieve as possible.

Left: mashing the simple syrup in a saucepan. Right: straining the simple syrup in a sieve.
Mash the berries as much as possible to extract maximum flavor from the blackberries.

Let cool completely before using in a recipe. Store in an airtight container in the refrigerator for up to 4 weeks, or freeze in ice cube trays and transfer to a sealed bag or container for up to 6 months.

Left: strained simple syrup. Right: finished bottled simple syrup.
Store in the refrigerator for a few weeks, or freeze in ice cube trays for long term storage.

Uses For Blackberry Simple Syrup

This simple syrup is super versatile and can be used in much more than cocktails! Here are a few of our favorite ways to use it:

  • Cocktails: It can be used in place of simple syrup, agave or another liquid sweetener. It goes well with gin, vodka, tequila and whiskey! Try it in some of our favorite drinks that use simple syrup:
    • Blackberry Bourbon Smash
    • Berry Basil Moscow Mule
    • Sparkling Berry Sangria
  • Mocktails/cold drinks: Add it to a non-alcoholic drink to add a splash of sweetness. It would be delicious in iced tea, lemonade, or a simple spritzer with sparkling water.
  • Stir it into yogurt, chia pudding, oatmeal or overnight oats as a sweetener.
  • Swap with maple syrup for pancakes, waffles, or french toast.
  • Desserts: Use it to add flavor to cakes, cupcakes and cheesecakes. It can also be used as a glaze for pound cakes/bundt cakes or drizzled over ice cream.

Tips and FAQs

  • Refrigerator storage: You can store this simple syrup in a mason jar or any other sealed container and stash it in the fridge, where it'll keep for up to 3-4 weeks. If you notice an off smell or mold anywhere in the container, discard. It's important to store it in an airtight container to extend the shelf life.
  • Freezer storage: Freeze in an ice cube tray and defrost one or two cubes at a time when you need some simple syrup. When frozen, it should keep for 3-6 months, so you can enjoy it any time.
  • Don't boil for too long: If this boils for too long, it will thicken up a bit too much. After 4 or so minutes, be sure to remove from heat to cool. If it thickens too much, add in more water.
  • This blackberry simple syrup is great as a DIY gift! Store it in a pretty glass container, wrap a ribbon around the top with a label, and you've got an awesome host/hostess or holiday gift on your hands!
    • Pair it with a bottle of our homemade infused alcohol for an extra special gift.

      You can always add a splash of water to thin it out!
