7 Ways to Make & Master Homemade Hazelnut Coffee Syrup
Mastering homemade hazelnut syrup requires careful attention to the process—from preparing the nuts to storing the final product. These seven actionable methods cover everything you need, whether you are a beginner or an experienced home barista looking for advanced techniques. We will start with the classic recipe, which provides the most aromatic hazelnut syrup through careful infusion.
1. Craft the Classic, Rich Homemade Hazelnut Coffee Syrup

Pin this simple syrup recipe to your ‘DIY Coffee Bar’ board!
The classic simple hazelnut syrup recipe is built on a standard 1:1 sugar-to-water ratio combined with freshly roasted nuts for maximum flavor. This proven method for hazelnut flavoring uses whole, roasted nuts to achieve a delicious depth that powdered or artificial flavorings cannot replicate, resulting in a true pure hazelnut syrup.
Ingredients
- 1 cup Granulated Sugar (or cane sugar)
- 1 cup Filtered Water (water quality matters)
- 1 cup Whole Hazelnuts (ensure premium hazelnuts selection)
- 1 tsp Vanilla Extract (optional, enhances latte flavor)
Instructions
- Toast Hazelnuts: If not already roasted, lightly toast hazelnuts on a baking sheet until fragrant and skins begin to peel (approx. 8-10 minutes). Chop coarsely to help flavor extraction.
- Combine Sugar and Water: In a medium saucepan, combine sugar and water. Stir until combined over medium heat to fully dissolve sugar, creating a basic simple syrup.
- Simmer and Infuse: Add the chopped, roasted hazelnuts to the syrup mixture. Bring to a gentle simmer for 5-7 minutes. Do not boil vigorously to prevent excessive evaporation.
- Cool and Steep: Remove the pan from heat and allow the mixture to cool completely while the nuts steep. This cooling and steeping process should last at least 45 minutes, up to 1 hour, for a perfect hazelnut syrup.
- Strain and Bottle: Strain the syrup through a fine-mesh sieve or cheesecloth to filter hazelnut bits and sediment. Bottle the finished homemade simple syrup into an airtight container.
Pro-Tip: The Maillard reaction in hazelnut roasting is essential for unlocking the deep, nutty hazelnut flavor. Always use freshly roasted nuts for the most aromatic hazelnut syrup. Do not skip the steeping time, as this is where the maximum flavor extraction occurs.
2. Make Sugar-Free Hazelnut Syrup for Healthy Lattes

Share this healthy alternative with your ‘Keto Recipes’ followers!
You can easily create a sugar-free hazelnut coffee syrup using granulated sugar substitutes like monk fruit or erythritol, perfect for meeting specific dietary requirements. These substitutions require minor adjustments, primarily focused on maintaining syrup viscosity optimization, as they do not thicken or caramelize like traditional sugar. This results in a healthy homemade hazelnut coffee syrup that still carries a decadent, nutty taste.
Supplies Needed
- 1 cup Filtered Water
- 1 cup Granulated Sugar Substitute (e.g., monk fruit or erythritol)
- 1 cup Whole Roasted Hazelnuts
- Optional: 1/4 tsp Xanthan Gum (for syrup viscosity optimization)
Process Modifications
- Combine Substitutes: In a medium saucepan, combine the water and the granulated sugar substitute. Stir until fully dissolved, ensuring the sweetener is fully integrated before heating.
- Simmer Carefully: Add the roasted hazelnuts and bring the mixture to a very gentle simmer. Sugar substitutes do not caramelize like sugar, so monitor heat closely to avoid scorching.
- Thicken (Optional): If a thicker viscosity is desired (as sugar substitutes often result in a thinner liquid sweetener), dissolve a small amount of xanthan gum into a tiny amount of syrup and whisk into the main batch off-heat.
- Steep and Strain: Allow the mixture to steep for 60 minutes for maximum flavor extraction. Strain carefully and store as directed in step 5.
Pro-Tip: Sugar substitutes can sometimes crystalize more easily than traditional sugar. To prevent syrup crystallization, ensure the mixture is completely cool before bottling and store it in the refrigerator immediately.
3. The Quick Method: Using Hazelnut Extract vs. Real Nuts

Save this easy, quick syrup recipe when you’re short on time!
For a quick hazelnut syrup, you can make a standard simple syrup recipe basic and infuse the flavor using hazelnut extract instead of whole nuts. This saves the time needed for roasting and steeping, though you sacrifice some of the complex, rich hazelnut flavor that comes from the real nuts. This method requires careful dosing of the high concentration flavor extract.
Supplies Needed
- 1 cup Granulated Sugar
- 1 cup Filtered Water
- 1-2 tsp Pure Hazelnut Extract (high concentration flavor)
- Optional: Pinch of salt (to balance sweetness)
Quick Steps
- Dissolve Sugar: Combine water and sugar in a small saucepan. Heat over medium heat, stirring until the sugar is fully dissolved. Do not boil for long; merely bring the mixture to a gentle boil for 1 minute to ensure full dissolution.
- Cool Slightly: Remove the syrup from the heat and let it cool for 5 minutes. Adding the extract to boiling syrup can cause thermal degradation of flavors.
- Stir in Extract: Once slightly cooled, stir in 1 teaspoon of hazelnut extract. Taste test and add a second teaspoon only if a very strong flavor is desired.
- Bottle: Cool completely before bottling. Use immediately in your specialty coffee drinks.
Pro-Tip: The key difference between hazelnut extract vs real hazelnuts in syrup is complexity. Extracts offer a clean, pronounced hazelnut essence, while real nuts provide a richer, ‘nutty’ depth due to the fat content and compounds released during roasting. Use pure, high-quality extract for best results.
4. Optimize Flavor: How to Roast Hazelnuts for Syrup

See why roasting is the secret to rich hazelnut flavor!
Roasting whole hazelnuts is the single most important step for achieving optimal flavor extraction for your homemade simple syrup. The heat initiates the Maillard reaction, which transforms mild, raw hazelnut compounds into the deep, nutty essence required for a rich hazelnut flavor syrup. Culinary tips for syrup making emphasize proper nut roasting techniques explained here.
Tools Required
- Baking Sheet or Cast Iron Skillet
- Parchment Paper (optional, for easier cleanup)
- Kitchen Timer (essential for precision)
- Clean Kitchen Towel
Roasting Technique Steps
- Preheat: Preheat your oven to 350°F (175°C). Spread the whole, raw hazelnuts in a single layer on a parchment-lined baking sheet.
- Roast: Bake for 10–15 minutes. Watch constantly. The nuts are done when they are fragrant, lightly browned, and the skins start to crack and peel away.
- Cool and Rub: Immediately transfer the hot nuts to a clean kitchen towel. Fold the towel over the nuts and rub them vigorously together to remove the skins. This removes the bitter enzymatic browning layer.
- Chop: Coarsely chop the warm, skinned roasted hazelnuts before adding them to the simple syrup mixture to increase surface area for infusion.
Pro-Tip: Over-roasting will lead to a burnt flavor; under-roasting leads to weak hazelnut flavor. Aim for a rich brown color, not black. Using warm nuts directly in the simple syrup recipe will expedite the flavor infusion process.
5. Gourmet Flavor Pairings: Using Your Syrup in Specialty Drinks

Level up your morning routine with these gourmet pairings!
The rich, nutty flavor profile development for coffee syrups means homemade hazelnut coffee syrup is a perfect pairing for hot and cold specialty coffee drinks.

6. Essential Steps to Properly Store Homemade Hazelnut Syrup

Don’t let your DIY syrup spoil! Pin these storage hacks.
Proper storage is critical for the shelf life extension for homemade syrup, which averages 3–4 weeks. Because homemade syrups lack the chemical stabilizers and natural preservative techniques used commercially, implementing strict food safety for homemade syrup protocols is mandatory. This begins with thorough glass jar sterilization for storage and careful bottling.
Supplies Needed
- Airtight Glass Bottles or Jars (glass jar sterilization for storage recommended)
- Sterilizing Solution (or boiling water)
- Small Funnel
- Labeling Supplies
Storage Steps
- Sterilize: Before filling, ensure all jars and lids are thoroughly sterilized, either by boiling or using a food-grade sterilizing solution, which prevents mold in syrup.
- Cool Completely: Allow the strained hazelnut coffee syrup to cool entirely to room temperature before bottling. Sealing warm syrup creates condensation, which reduces shelf life.
- Bottle and Seal: Using a funnel, pour the syrup into the airtight containers, leaving about an inch of headspace. Seal tightly.
- Refrigerate: Homemade syrups must be refrigerated immediately. When stored correctly in the refrigerator, homemade simple syrup lasts approximately 3–4 weeks.
- Freeze (Optional): For longer storage (up to 3-4 months), consider freezing the syrup in small, measured portions.
Lesson Learned: The high sugar concentration of simple syrup naturally inhibits microbial growth (water activity in food storage), but unlike store-bought syrups with added natural preservative techniques, refrigeration is non-negotiable for homemade versions. Always check for cloudiness or mold before use.

FAQs About homemade hazelnut coffee syrup
How long does homemade hazelnut syrup last in the fridge?
Homemade hazelnut simple syrup will last approximately 3 to 4 weeks when stored correctly in the refrigerator in a sterilized, airtight container. The shelf life extension for homemade syrup is dependent on the sugar concentration, but because it lacks commercial preservatives, refrigeration is mandatory. Always check the syrup before use; if it appears cloudy or has mold, discard it immediately to ensure food safety for homemade syrup.
What is the ratio for hazelnut simple syrup?
The classic ratio for making a standard simple syrup base is 1:1, meaning one part granulated sugar to one part water. When creating homemade hazelnut coffee syrup, you typically add the hazelnuts using a 1:1:1 ratio (1 cup sugar, 1 cup water, 1 cup hazelnuts). This consistency is ideal for flavoring coffee and ensures proper sugar inversion and syrup viscosity.
Can I make hazelnut syrup without roasting the nuts?
While you can make the syrup without roasting the nuts, skipping this step will result in a much weaker hazelnut flavor profile. Roasting hazelnuts is essential because the heat triggers the Maillard reaction, which deepens the nutty, rich hazelnut flavor. If you choose not to roast, increase the steeping time to compensate, but the flavor will still lack the authentic depth of a roasted hazelnut coffee syrup.
What kind of sugar should I use for homemade coffee syrup?
Granulated white sugar or pure cane sugar is recommended for its neutral flavor profile, which allows the rich hazelnut flavor to shine. While brown sugar or honey can be used as alternatives, they will significantly alter the flavor profile of the syrup, often competing with the delicate hazelnut essence. For sugar-free hazelnut coffee syrup, use substitutes like monk fruit or erythritol, adjusting quantities based on their relative sweetness.
How much hazelnut syrup should I add to my latte?
For a standard 12-16 ounce latte, begin by adding 1 to 1.5 tablespoons of homemade hazelnut coffee syrup, adjusting to taste. Because homemade simple syrup is often purer and less diluted than commercial syrups, you might require less to sweeten and flavor your drink adequately. Experienced home barista typically adjust based on the strength of the espresso or coffee brew.
Can I use hazelnut extract instead of real nuts in the syrup?
Yes, you can use hazelnut extract for a quick hazelnut syrup, but it will yield a less complex flavor than using real hazelnuts. The extract provides a clean, potent hazelnut essence, whereas real roasted hazelnuts infuse fat and depth for a rich hazelnut flavor syrup. Use the extract method (1-2 tsp per cup of syrup) if time is limited, but recognize the difference in flavor complexity homemade vs store.
How do you prevent homemade syrup from crystallizing?
To prevent syrup crystallization, ensure the sugar is fully dissolved before the mixture reaches a boil, and avoid over-stirring once boiling has begun. Additionally, ensuring your simple syrup ratios for consistency are correct (1:1 ratio) helps stabilize the solution. Storing the syrup in sterilized containers and refrigerating it immediately after cooling also minimizes the risk of sugar crystal formation.
Is homemade hazelnut syrup healthier than store-bought options?
Homemade hazelnut coffee syrup is generally considered healthier because you eliminate artificial flavors, high-fructose corn syrup, and unnecessary preservatives often found in commercial brands. By controlling the ingredients, you can ensure a natural hazelnut coffee flavoring and easily adjust the sweetness level or substitute refined sugar entirely, helping users find natural hazelnut syrup.
What drinks can I use hazelnut syrup in besides coffee?
Hazelnut syrup is incredibly versatile and can be used to flavor hot chocolate, iced teas, milkshakes, and as a decadent dessert topping for ice cream or pancakes. Its nutty, sweet profile pairs with coffee beautifully, but also acts as a sophisticated cocktail ingredient, especially complementing bourbon or rum-based drinks, making it a valuable liquid sweetener for various uses.
Why do my hazelnuts turn bitter after infusion?
Hazelnuts can turn bitter after infusion if they were over-roasted initially or if the syrup mixture was simmered too long and too vigorously. Over-roasting can lead to thermal degradation of flavors. Furthermore, excessive simmering can cause the syrup to reach too high a temperature, potentially extracting bitter compounds from the nuts. Always use a gentle simmer and adhere to the recommended steeping time for a perfect hazelnut syrup.
