This blueberry simple syrup is made using just 3 ingredients and is amazing on pancakes, waffles, cakes, or in cocktails!!

What is Blueberry Simple Syrup?

Simple syrup is usually made with equal parts water and sugar. The mixture is heated to help the sugar dissolve, which yields a sweet syrup that can be used to sweeten and flavor just about anything!

This recipe makes a blueberry simple syrup by adding in a cup of blueberries and a bit of lemon juice and zest.

The blueberries pack this syrup with flavor and give it a beautiful purple color.

Blueberry Simple Syrup Ingredients & Substitutions

Like I mentioned above, this recipe is pretty straight forward! However, there are some substitutions and swaps you can make if needed.

• Water – Room temperature tap water works great in this recipe.
• Granulated Sugar – I like using granulated sugar because it’s what I usually have on hand, but you can also use extra fine sugar or caster sugar.
• Blueberries – You can use fresh or frozen blueberries in this recipe. If you use frozen I recommend simmering the mixture a couple extra minutes!
• Lemon Zest and Juice – The fresh lemon zest and juice in this recipe really brighten the flavor of the syrup. I don’t recommend skipping it, but if you don’t have a lemon on hand the syrup will still turn out without it.

How Do You Make Blueberry Simple Syrup?

I love this recipe because it seriously takes less than 5 minutes to make!

Start by pouring the granulated sugar, water, blueberries, and the zest and juice of 1 small lemon into a small saucepan.

Cook over medium heat, and stir continuously until the mixture just starts to boil. It usually takes about 3 minutes for my simple syrup to reach a boil.

Reduce the heat and allow the mixture to simmer for 5-8 more minutes. The blueberries should burst during this process.

If I’m making this for drinks I usually simmer for about 5 minutes, but if I’m making this for pancakes or waffles I usually simmer for about 8 minutes to let it thicken up a bit.

Remove from heat and pour into a medium-sized bowl to cool to room temperature, then cover and set aside.

If you’re making this in advance, it can be stored in an airtight container in the fridge for up to 2 weeks. 

How Can You Use this Blueberry Simple Syrup?

I’m sure it’s no surprise, but my favorite way to use blueberry simple syrup is to brush it on cake layers!!

It adds both moisture and flavor, and truly makes any cake irresistible.

I highly recommend leveling each cake layer before adding the syrup, so they can easily absorb the syrup.

You can use a silicone pastry brush or a plastic squirt bottle to generously soak each cake layer with syrup. The entire top of the cake layer should look moist once you’ve added it.

I usually brush my cake layers with simple syrup right before I assemble a cake.

If you want to make / freeze cake layer in advance, I recommend thawing them and then adding the simple syrup just before you frost the cake.

I use this technique in my Berry Chantilly Cake recipe, and it really takes the cake to the next level.

This blueberry simple syrup also tastes amazing in cocktails, milkshakes, or even with ice cream. The sky is really the limit!

How Do You Store Blueberry Simple Syrup?

This recipe can be made in advance, or leftovers can be stored in an airtight container in the fridge for up to 2 weeks.

I usually keep mine in a mason jar, but any container with a good lid should work just fine.
