How to Make Starbucks Chai Syrup at Home (With Natural Ingredients)

If you’ve ever sipped on a Starbucks chai latte and thought, I wish I could make this at home, you’re not alone.

That warm blend of black tea, sweet spices, and a touch of vanilla is both comforting and energizing.

The good news? You can recreate that signature flavor in your own kitchen — and make it even better by using natural ingredients without artificial flavors or preservatives.

This homemade Starbucks chai syrup is perfect for lattes, iced teas, or even baking. Once you try it, you’ll wonder why you ever bought the store-bought version.

Why Make Your Own Chai Syrup?

All-natural ingredients – no artificial colors, flavors, or high fructose corn syrup.
Customizable spice level – make it mild and sweet or bold and spicy.
Cost-effective – one batch can make 10–15 chai lattes for a fraction of the coffee shop price.
Fresh taste – spices are simmered fresh, creating a richer, more aromatic syrup.

Ingredients You’ll Need

To make about 2 cups of chai syrup, gather the following:

2 cups water
1 cup raw sugar (or coconut sugar for a richer flavor)
4 black tea bags (or 4 tsp loose-leaf Assam tea)
2 cinnamon sticks
6 whole cardamom pods, lightly crushed
6 whole cloves
1 tsp whole black peppercorns
1–2 star anise
1-inch fresh ginger root, sliced
1 tsp pure vanilla extract

Step-by-Step Instructions

1. Prepare the Spices

Lightly crush the cardamom pods with the side of a knife to release their aroma. Slice the fresh ginger into thin pieces.

Having your spices prepped ensures maximum flavor infusion.

2. Simmer the Base

In a medium saucepan, bring 2 cups of water to a gentle boil. Add the cinnamon sticks, cardamom, cloves, peppercorns, star anise, and ginger. Reduce the heat to low and let the spices simmer for 10 minutes.

This slow simmering releases the oils from the spices and creates a deep, complex flavor.

3. Add the Tea

After 10 minutes, add the black tea bags (or loose tea in a tea infuser) to the pot. Steep for 5 minutes — any longer and the tea can become overly bitter.

4. Sweeten the Syrup

Remove the tea bags and stir in 1 cup of raw sugar until fully dissolved. For a less processed option, you can use honey or maple syrup, though they will slightly change the flavor profile.

5. Add Vanilla

Remove the saucepan from heat and stir in 1 teaspoon of pure vanilla extract.

The vanilla rounds out the bold spices and adds the signature smooth Starbucks finish.

6. Strain and Store

Strain the syrup through a fine mesh sieve into a clean glass jar or bottle. Let it cool completely before sealing. Store in the refrigerator for up to 2 weeks.

How to Use Your Homemade Chai Syrup

Hot Chai Latte: Mix 2–3 tablespoons of syrup with 1 cup steamed milk.
Iced Chai Latte: Combine syrup with milk over ice for a refreshing drink.
Chai Cold Brew: Add syrup to cold brew coffee for a spicy twist.
Baking: Drizzle over pancakes, waffles, or oatmeal for instant chai flavor.

Tips for the Perfect Chai Syrup

Adjust Sweetness: Start with less sugar and add more to taste.
Boost the Spice: Double the ginger or add extra cinnamon for a bolder chai.
Tea Choice Matters: Assam or Darjeeling tea provides the best rich base for chai syrup.
Make it Creamy: Add a splash of coconut milk directly to the syrup for a dairy-free creamy chai concentrate.

Things to Avoid When Making Chai Syrup

Over-steeping the tea – leaving tea bags in too long can make the syrup bitter.
Using ground spices instead of whole – ground spices make the syrup cloudy and gritty, while whole spices infuse a cleaner flavor.
Skipping the simmer – rushing the spice simmering step results in a flat-tasting syrup.
Using artificial vanilla – real vanilla extract gives a smoother, more authentic taste.
Not straining properly – leftover spice bits can affect texture and shelf life.
Storing at room temperature – always refrigerate to keep the syrup fresh and safe to consume.
