Blue Raspberry Syrup Recipe – Explosive Flavor & Electric-Blue Color

I have recently made blue raspberry syrup. It’s a pourable syrup that you can use in all kinds of drinks and desserts. 

The best thing is, it’s actually simple, and once you make it, you won’t ever look back at those store-bought bottles again.

 

How to Make Blue Raspberry Syrup

Blue raspberry syrup is a sweet, tangy syrup that will give your drinks and desserts a bold, electric-blue look with a fruity candy taste. 

It’s not the same as regular raspberry — it’s a mix of tart berry flavor with a fun twist. 

And that makes it perfect for slushies, lemonades, and iced drinks.

Ingredients:

Here’s how you can make this berry syrup recipe. Let me break it down — because how we choose our ingredients will affect the taste, texture, and overall feel of our syrup.

• Sugar (2 cups): You will want to use white granulated sugar; it works perfectly here for a clean taste. Besides this, you can use cane sugar, but avoid brown sugar because it will darken the color and alter the flavor.
• Water (1 cup): Just use plain filtered water, nothing fancy. You will need it for the base.
• Raspberries (1 cup): You can use fresh or frozen, both are good. These will give a natural fruitiness. Also, remember that traditional blue raspberry flavor is made from whitebark raspberry or a blend with apple, but regular raspberries still give that tangy backbone.
• Lemon juice (2–3 tablespoons): It will add the acidity and will brighten the flavor. So, you wanna use it to balance the syrup’s sweetness.
• Blue raspberry extract (½ teaspoon): This is what gives that iconic taste and smell. If you don’t have an extract, I’ll show you the substitutions below.
• Blue food coloring (a few drops): For that bold electric blue. Natural spirulina blue also works if you don’t want artificial dyes.

Instructions:

Let’s walk through the process in easy steps. It’s too easy and simple:

Step 1: Make a Simple Syrup Base

• You wanna take a saucepan, and combine sugar and water.
• Bring to a gentle simmer, and meanwhile keep stirring occasionally until the sugar isn’t dissolved fully.
• This will be the base that will give body to the syrup.

Step 2: Add Fruit for Tang

• You want to toss in your raspberries and simmer for about 8 to 10 minutes.
• In these 10 minutes, these berries will break down and release color and tanginess into the syrup.
• Once they’re broken down, then mash them with the back of a spoon. By doing so, you can extract more raspberry flavor.

Step 3: Strain the Mixture

• Remove the pan from the heat and strain that syrup through a sieve.
• While straining, you can press the berries well with a hand or spoon to get all the juices out.
• Finally, discard the solids.

Step 4: Add Flavor Boost

• You want to stir in lemon juice. This will brighten the syrup and will keep it tasting good.
• After that, you will add blue raspberry extract (start with ½ teaspoon, taste, and adjust).
• Then, drop in a few drops of blue food color until you get a classic bright blue shade.

Step 5: Cool & Store

You wanna cool this syrup at room temperature or in the fridge. 

Once done!

Then, transfer it into a glass bottle. And keep that bottle in the fridge, and use it whenever you want.

Pro tip: You should always cool the syrup before sealing it. If you bottle it hot, condensation will form and shorten its shelf life.

Ingredient Notes & Substitutes

• Sugar alternatives: You can swap with monk fruit or erythritol, but they won’t give the same syrupy body.
• Fruit swap: No raspberries? Use a mix of blueberries and tart apple juice concentrate. This mimics the tangy-sweet profile well.
• Blue raspberry extract substitutes: Can’t find it? Try raspberry extract plus a few drops of candy flavor oil like “tropical punch” to replicate that same kick.
• Want powder form? If you’re wondering how to make blue raspberry powder, you can actually dehydrate the syrup by spreading it thinly on a tray and drying it into crystals — more on that later.

 

Variations You Can Try

• Blue Raspberry Lemonade Syrup: You can add extra lemon juice and zest during the simmering stage to make it ready for mixing directly with cold water or soda.
• Candy-Style Syrup: Add a drop of cotton candy flavoring with the extract for a sweeter, nostalgic taste.
• Blue Raspberry Chocolate Sauce: Blend the syrup with melted dark chocolate and drizzle over brownies, cakes, or even my Chocolate Fudge with Marshmallow Fluff.
• Powder Form: If you’ve ever wondered “how to make blue raspberry powder,” just spread your syrup thinly onto a silicone mat, dehydrate it at a low temperature until crisp, and grind it into a fine powder.

 

How to Use Blue Raspberry Syrup

This is where the fun starts. Once you have the syrup, you can serve it with many things. Here are a few options that I have tried, and some that I didn’t, but I will:

Drinks

• You will have to mix 2 tablespoons into sparkling water when you’re making an instant soda.
• You can stir this syrup into lemonade to make blue raspberry lemonade.
• Blend with ice to make slushies.

Desserts

• It will taste good if you pour it on ice cream or in frozen yogurt.
• Pour into shaved ice or snow cones.
• Use as a cake soak for vibrant layers.

Pairings

Just like how I always mention in my chocolate recipes, the pairing game makes it fun:

• Simple Pairings: Lemonade, Sprite, sparkling water, 7 Brew ocean breeze drink, Starbucks copycat
• Crunchy & Textural: Chocolate covered Pretzels or chocolate popcorn topped with a drizzle for sweet-salty play.
• Dessert Pairings: Cheesecake, panna cotta, or custard pudding (like my Eggless Custard Pudding with Custard Powder).
• Drink Pairings: Try adding it to coffee-free Starbucks-style drinks, just like I showed in my Starbucks Dubai Chocolate Drink Recipe.

 

Storage & Shelf Life

• Fridge: You have to store it in a sealed glass jar or bottle. And keep that bottle in the fridge, your sauce will remain ready to use for up to 3 to 4 weeks.
• Freezer: You can also freeze in ice cube trays. 

 

Troubleshooting & Tips

• Is it too thin? You can simmer longer to reduce and thicken.
• Too thick? Stir in a tablespoon of hot water to loosen it.
• Not tangy enough? You should add an extra tablespoon of lemon juice or citric acid.
• Color not vibrant? Don’t overuse food coloring. A small drop of gel food color is more intense than liquid.

 

Nutrition Snapshot

A tablespoon of this syrup is about 50 calories (all from sugar). 

But, if you want lighter, go with monk fruit sweetener — but remember it won’t have the same syrup body.
