How to Make Flavored Coffee at Home (Vanilla, Caramel, Hazelnut)
Homemade vanilla caramel and hazelnut coffee syrups beside a latte

Flavored coffee drinks at a café can cost $6–8 each — but the syrups that make them are surprisingly simple and cheap to make at home. Once you have a few homemade syrups in your fridge, you can recreate virtually any flavored coffee drink in minutes. Here's how to make the three most popular flavors: vanilla, caramel, and hazelnut.

The Base: Simple Syrup

All flavored coffee syrups start with a simple syrup base: equal parts sugar and water, heated until dissolved. From there, you add your flavoring. The ratio is always the same — only the flavoring changes.

Base recipe: 1 cup water + 1 cup sugar → makes approximately 1.5 cups of syrup, enough for 15–20 drinks.

Vanilla Syrup

The most versatile flavored syrup — works in lattes, cold brew, iced coffee, and even matcha.

Ingredients:

  • 1 cup water
  • 1 cup white sugar
  • 2 teaspoons pure vanilla extract (or 1 vanilla bean, split)

Method:

  1. Combine water and sugar in a small saucepan over medium heat
  2. Stir until sugar is fully dissolved (3–5 minutes) — do not boil
  3. Remove from heat and stir in vanilla extract
  4. Let cool completely, then transfer to a glass bottle or jar
  5. Refrigerate for up to 3 weeks

Use: 1–2 tablespoons per drink. Perfect in a latte made with the Blueprint Coffee Penrose Espresso Blend — the natural sweetness of the beans pairs beautifully with vanilla.

Caramel Syrup

Richer and more complex than vanilla, caramel syrup adds a buttery, toasty sweetness to any coffee drink.

Ingredients:

  • 1 cup white sugar
  • ¼ cup water (for caramelizing)
  • ¾ cup hot water (to finish the syrup)
  • Pinch of sea salt (optional but recommended)

Method:

  1. Combine sugar and ¼ cup water in a saucepan over medium-high heat — do not stir
  2. Cook until the mixture turns a deep amber color (8–10 minutes), swirling the pan occasionally
  3. Remove from heat and carefully pour in ¾ cup hot water (it will bubble vigorously)
  4. Stir until smooth, add sea salt if using
  5. Cool completely and store in a glass bottle in the fridge for up to 2 weeks

Use: 1–2 tablespoons per drink. Exceptional in an iced latte or drizzled over cold brew.

Hazelnut Syrup

Nutty, warm, and slightly sweet — hazelnut syrup transforms a simple latte into something special.

Ingredients:

  • 1 cup water
  • 1 cup sugar
  • ½ cup roasted hazelnuts, roughly chopped
  • ½ teaspoon hazelnut extract (optional, for stronger flavor)

Method:

  1. Combine water, sugar, and hazelnuts in a saucepan over medium heat
  2. Stir until sugar dissolves, then simmer for 10 minutes
  3. Remove from heat and let steep for 30 minutes
  4. Strain through a fine mesh sieve, pressing the hazelnuts to extract maximum flavor
  5. Add hazelnut extract if desired, cool, and bottle
  6. Refrigerate for up to 2 weeks

Use: 1–2 tablespoons per drink. Pairs beautifully with dark roast coffee like the DRINK COFFEE DO STUFF Dark Roast Whole Bean.

Tips for Using Homemade Syrups

  • Add syrup to espresso first — stir it into the hot shot before adding milk so it dissolves completely
  • Taste and adjust — start with 1 tablespoon and add more to taste
  • Label your bottles with the date made — syrups keep 2–3 weeks refrigerated
  • Try combinations — vanilla + caramel, hazelnut + vanilla, or caramel + sea salt are all excellent

Quick Flavored Coffee Ideas

  • Vanilla Iced Latte: 2 shots espresso + 1 tbsp vanilla syrup + ice + oat milk
  • Caramel Cold Brew: Cold brew + 1 tbsp caramel syrup + ice + splash of cream
  • Hazelnut Flat White: 2 shots espresso + 1 tbsp hazelnut syrup + steamed whole milk
