Homemade Coffee Syrup Recipes: Vanilla, Caramel, and Hazelnut
Key Takeaways
- Simple syrup (equal parts sugar and water, dissolved) is the base for all flavored coffee syrups
- Vanilla, caramel, and hazelnut cover the most common café flavor profiles and are all achievable at home
- Homemade syrups refrigerate for 2–4 weeks and cost significantly less than commercial equivalents
Almost every flavored coffee drink at a café — vanilla latte, caramel macchiato, hazelnut coffee — gets its sweetness and flavor from a bottled syrup. Making these at home is straightforward for most flavors, costs a fraction of the commercial product, and allows you to control sweetness and intensity.
Homemade Coffee Syrup Recipes: Vanilla, Caramel, and Hazelnut
Ingredients
- 200g (1 cup) granulated white sugar
- 200ml (3/4 cup + 1 tbsp) water
Steps
- 1.材料を準備する
- 2.抽出する
- 3.仕上げて完成
Basic Simple Syrup
The foundation for all flavored syrups. Most café syrups are diluted variations of this.
Ingredients (makes ~300ml)
- 200g (1 cup) granulated white sugar
- 200ml (3/4 cup + 1 tbsp) water
Method: Combine sugar and water in a small saucepan over medium heat. Stir occasionally until the sugar fully dissolves. The mixture does not need to boil — remove from heat as soon as it is clear. Cool completely before transferring to a clean glass jar. Refrigerate.
Vanilla Syrup
Ingredients
- 300ml simple syrup (above)
- 1 vanilla bean (or 2 tsp vanilla extract)
Method
Split the vanilla bean lengthwise and scrape out the seeds. Add both the seeds and the pod to the sugar-water mixture before heating. Simmer gently for 10 minutes. Cool, remove the pod, and transfer to a jar.
Using extract instead: If vanilla beans are unavailable, add 2 tsp vanilla extract to the cooled simple syrup and stir. Do not add extract to hot syrup — the flavor will partly cook off. Extract-based syrup works well and is significantly cheaper.
Use: 1–2 tbsp per drink in lattes, iced coffee, cold brew, or milk-based drinks.
Caramel Syrup
Caramel requires more attention than other syrups but produces a result close to commercial caramel sauce.
Ingredients
- 200g (1 cup) granulated white sugar
- 2 tbsp water (for initial caramelization)
- 100ml (7 tbsp) heavy cream or whole milk, warm
Method
- Combine sugar and 2 tbsp water in a small heavy saucepan over medium heat
- Do not stir — swirl the pan occasionally as the sugar melts and begins to color
- Continue until the sugar turns a deep amber color (about 5–7 minutes from first color)
- Remove from heat immediately and pour in the warm cream slowly in a thin stream
- Stir vigorously — it will bubble violently then settle to a smooth sauce
- Cool before transferring to a jar
Safety note: Caramelized sugar reaches temperatures above 170°C (340°F). Use a long-handled spoon and oven mitts when adding cream. Add cream gradually, not all at once, to control the bubbling reaction.
Hazelnut Syrup
Ingredients
- 300ml simple syrup
- 1–2 tsp hazelnut extract
- Optional: 50g (1/2 cup) toasted hazelnuts
Method
Extract method (fast): Add hazelnut extract to cooled simple syrup and stir. Adjust amount based on desired intensity.
Infusion method (more natural): Add toasted hazelnuts to the sugar and water before heating. Simmer 15 minutes. Cool fully, then strain through a fine mesh sieve or cheesecloth.
Lavender Syrup
Ingredients
- 300ml simple syrup
- 1 tbsp dried culinary lavender
Method
Add dried lavender to the sugar and water before heating. Once sugar dissolves, remove from heat, cover, and steep 10–15 minutes. Strain through a fine mesh sieve. Do not simmer too long — lavender becomes bitter when overcooked.
Storage and Dosage Reference
| Syrup | Refrigerator life | Per drink |
|---|---|---|
| Simple syrup | ~4 weeks | 1–2 tbsp |
| Vanilla syrup | 2–3 weeks | 1–2 tbsp |
| Caramel syrup | 2–3 weeks | 1 tbsp |
| Hazelnut syrup | 2–3 weeks | 1 tbsp |
| Lavender syrup | 2–3 weeks | 1 tsp |
Summary
- Equal parts sugar and water, dissolved, is all simple syrup requires
- Vanilla: infuse vanilla bean in warm syrup, or add extract to cooled syrup
- Caramel: dry or wet caramelization followed by cream addition — watch the temperature
- Hazelnut: extract method is fast; nut infusion method produces more nuanced flavor
- Store refrigerated in clean glass jars; label with date made
