Homemade Hazelnut Syrup
Made from toasted hazelnuts and simple pantry elements, this syrup captures the nutty, buttery richness of hazelnuts and transforms it into a versatile liquid gold. It’s the kind of kitchen staple that effortlessly upgrades everything it touches — from your first sip of morning coffee to an after-dinner cocktail or a drizzle over dessert.
This isn’t just “hazelnut flavor” from a bottle of lab-made “natural flavors.” It’s the real thing — warm, toasty, slightly praline-like, with notes that remind you of browned butter, a whisper of cocoa, and a soft, rounded finish. Whether you make it to create a clean, all-natural coffee creamer or to experiment in the kitchen, one batch will have you finding excuses to use it.
Flavor profile & mood
Hazelnut syrup is more than sweetness; it’s an accent. Toasting the nuts brings out caramelized depth and a subtle smokiness that plays beautifully against the syrup’s sugar-balanced backbone. On the palate, it reads warm, cozy, and rounded — like comfort in a bottle. The flavor feels seasonal even in the middle of summer, making it just as welcome in an iced latte as it is in a holiday dessert.
Why make your own hazelnut syrup?
Because so many people love their hazelnut coffee creamer, I wanted to give them something they could enjoy in an all-natural way — no gums, no chemical flavorings, no citric acid. This syrup delivers exactly that, with the added bonus of being multi-use. Stir it into coffee or tea, mix it into cocktails, brush it over cakes, or swirl it into oatmeal.
What you’ll need (and what you won’t)
Just hazelnuts, water, and a sweetener — your choice of organic cane sugar, maple syrup, honey, or date sugar.
Ingredient check: When buying hazelnuts, the ingredient list should say only “hazelnuts” — nothing else. Skip any that include added oils, salt, or preservatives.
Ways to use it (beyond coffee)
Coffee & tea: Try it in iced coffee for a dessert-like treat or in black tea to add depth without heaviness.
Cocktails & mocktails: Pairs beautifully with bourbon, rum, or even citrus-forward drinks.
Baking & desserts: Drizzle over panna cotta, mix into whipped cream, or finish a caramel tart.
Breakfast upgrades: Swirl into oatmeal, yogurt, or over pancakes.
Savory surprises: Add a drop or two to marinades or glazes for roasted vegetables or pork — used sparingly, it builds complexity.
Presentation & gifting
Poured into a simple glass bottle and tied with a kraft tag, hazelnut syrup becomes a thoughtful homemade gift. Include serving suggestions for coffee, cocktails, and desserts — it’s perfect for holiday baskets, host gifts, or a neighborly surprise.
Homemade Hazelnut Syrup for Coffee & Desserts
Ingredients
- 1 cup roasted, unsalted hazelnuts (unsalted is important so your syrup’s flavor stays balanced)
- 1½ cups water
- Pinch of fine sea salt
Choose one sweetener (start with ¾ cup, add more to taste):
- 3/4 cup pure cane sugar
- 3/4 cup maple syrup
- 3/4 cup honey
- 3/4 cup date sugar
Instructions
- Roast the nuts. Preheat oven to 350°F (175°C). Spread hazelnuts on a sheet pan and roast 8–10 minutes until fragrant and skins crack.Or toast in a dry skillet over medium heat for about 5 minutes, shaking often.Even if your hazelnuts are already roasted, this quick step helps refresh their flavor and release natural oils for a richer syrup.Remove most skins & chop.If your hazelnuts still have skins, wrap the warm nuts in a clean towel and rub to loosen them—don’t stress over perfection.If you’re starting with already roasted, unsalted hazelnuts, they usually come skin-free, but chopping them is still important. Smaller pieces mean more surface area, which helps the flavor infuse into the water faster and more fully.Infuse. Add nuts and water to a small saucepan. Bring to a boil, cover, reduce the heat, and simmer for 15–20 minutes. Turn off the heat, keep covered, and steep for another 15–20 minutes (longer steep = bolder flavor).Strain. Pour through a fine-mesh sieve lined with cheesecloth, pressing to extract liquid. Discard (or save!) the nuts.Sweeten. Return the hazelnut infusion to the pan. Add your chosen sweetener and a pinch of salt. Warm just until dissolved—don’t boil hard. Stir in vanilla if using.Bottle & chill. Cool to room temp, then transfer to a clean glass bottle/jar. Refrigerate. Shake before each use.
