Peppermint Syrup Recipe for Coffee

This peppermint syrup for coffee brings cool, sweet mint flavor to your favorite drinks with just three simple ingredients.

It takes about 10 minutes to make, and a small splash turns brewed coffee, espresso, or cold brew into a cozy treat.

Adjust the flavor to make a gentle mint syrup or a bolder version for peppermint mochas and holiday lattes.

Unlike store-bought bottles, this homemade coffee syrup has no preservatives and lets you control the sweetness. Keep a jar in the refrigerator for hot coffee, iced coffee, tea, or whipped cream.

No special equipment or advanced cooking skills are needed: dissolve sugar in water, cool the syrup, and stir in peppermint extract.

Once you make a batch, you’ll want it in your coffee station whenever minty coffee sounds good.

Why You’ll Love This Peppermint Syrup for Coffee

This recipe is quick, reliable, and made with pantry staples.

You don’t need to simmer fresh mint leaves or strain anything, and the peppermint extract gives the syrup a clear, recognizable mint flavor. The result blends smoothly into both hot and cold drinks.

You can also adjust the strength and sweetness. Start with a teaspoon in your coffee, taste, and add more if you like a sweeter drink.

That makes it easy to use the same batch for a subtle morning coffee or a more indulgent peppermint mocha.

It’s a handy homemade alternative to coffee-shop peppermint syrup, especially when you want to make a seasonal favorite at home.

Ingredients You’ll Need

Granulated sugar

White granulated sugar gives the syrup a clean, neutral sweetness and keeps the peppermint flavor bright.

Because the sugar dissolves completely in warm water, the finished syrup is smooth and easy to measure.

For the clearest mint flavor, use regular white sugar rather than a strongly flavored sweetener.

Water

Use an equal amount of water and sugar. This creates a standard simple syrup that pours easily and mixes into coffee without leaving crystals at the bottom.

Filtered water is a nice choice if your tap water has a noticeable taste, but regular drinking water works well.

Peppermint extract

Peppermint extract supplies the cool mint flavor. Extracts vary in strength, so the recipe starts with a modest amount.

Add it only after the syrup has cooled; heating peppermint extract can dull its aroma.

Note: Use peppermint extract, not spearmint extract, if you want the familiar flavor associated with peppermint coffee drinks.

Optional: a tiny pinch of salt

Salt is not essential, but a very small pinch can round out the sweetness, particularly in a mocha. Keep it subtle so it does not make the syrup taste salty.

How to Make Peppermint Syrup for Coffee

Step 1.

Combine the sugar and water. Add 1 cup of granulated sugar and 1 cup of water to a small saucepan.

Stir once to moisten the sugar. Place the pan over medium heat.

Step 2.

Warm until the sugar dissolves. Stir gently as the mixture heats. It should become clear, with no visible sugar granules on the bottom of the pan.

This usually takes about 3 to 5 minutes. The syrup doesn’t need to boil vigorously; take it off the heat as soon as the sugar has dissolved.

Step 3.

Cool the simple syrup. Set the saucepan aside and let the syrup cool until it is no longer hot, about 20 to 30 minutes.

Cooling before adding the extract helps preserve its fresh mint aroma and makes the syrup safer to transfer into a bottle.

Step 4.

Add the peppermint extract. Stir in ½ teaspoon peppermint extract. Taste a tiny drop once it has cooled.

If you want a stronger mint flavor, add more in small increments, up to another ¼ teaspoon. Extract can become sharp quickly, so taste as you go.

Step 5.

Transfer and chill. Pour the syrup into a clean jar or bottle, seal it, and refrigerate.

Label it with the date so you can keep track of freshness. The syrup is ready to use as soon as it is cold.

How to Use Peppermint Syrup in Coffee

To make a simple peppermint latte, mix 1 tablespoon of peppermint syrup into a double shot of espresso, then add about ¾ cup steamed milk.

For a peppermint mocha, stir 1 tablespoon syrup and 1 tablespoon chocolate sauce into the hot espresso, then top with steamed milk. Finish with whipped cream and a light dusting of cocoa if you like.

For iced coffee, dissolve the syrup in a small amount of hot coffee or espresso first, then pour it over ice and add cold milk.

Cold liquids can make thick or concentrated sweeteners harder to mix, but this simple syrup incorporates easily once stirred.

Tip: Use less syrup at first in a small drink; you can always add more after tasting.

Tips for the Best Homemade Peppermint Coffee Syrup

• Avoid boiling it for a long time. Gentle heat is all you need to dissolve the sugar. Extended boiling evaporates water and can make the syrup thicker and sweeter than intended.
• Add extract after cooling. Peppermint’s aroma is delicate. Stirring the extract into cooled syrup keeps the finished flavor fresh and distinct.
• Measure carefully, then taste. Peppermint can quickly overpower coffee. Begin at the lower amount, especially if your extract is concentrated or labeled “pure.”
• Use a clean spoon. Do not dip a used coffee spoon into the storage jar. Keeping the syrup free of milk and coffee helps it stay fresh longer.
• Sweeten the drink gradually. Coffee strength, cup size, and personal preference all affect how much syrup you need. Add a little, stir, and taste before adding more.

Easy Variations

• Make a stronger peppermint syrup: For a bolder flavor, increase the extract slowly after the syrup cools. Add ⅛ teaspoon at a time and taste between additions. A stronger batch is useful for recipes with chocolate or plenty of milk, which can soften mint flavor.
• Use brown sugar: Swap in light brown sugar for a warmer, molasses-like sweetness. It makes a delicious syrup for cold brew and pairs well with chocolate, though the mint flavor will taste less crisp than it does with white sugar.
• Try a reduced-sugar version: You can make a lighter syrup by using ¾ cup sugar with 1 cup water. It’ll be thinner and less sweet, so you may need a little more in each drink.
• Add vanilla: Stir in ¼ teaspoon vanilla extract after cooling for a softer, rounded flavor. Vanilla-peppermint syrup is especially good in lattes and hot chocolate. Keep the vanilla modest so the peppermint remains easy to taste.

Make-Ahead and Storage

Store peppermint syrup in a clean, tightly sealed jar or bottle in the refrigerator. For the standard recipe, use it within about 2 weeks for the best flavor and quality.

Always use a clean spoon or pour directly from the bottle, and discard the syrup if it develops an off smell, visible mold, or an unusual appearance.

The recipe is easy to halve if you only make coffee occasionally. You can also prepare it a day ahead; the peppermint flavor stays ready in the refrigerator whenever you want to make a latte or iced coffee.

Don’t store it at room temperature, since this is a homemade syrup without commercial preservatives.

Frequently Asked Questions

Can I use peppermint oil instead of peppermint extract?

Peppermint oil is much more concentrated and may not disperse in the syrup the same way. Use food-grade peppermint extract for this recipe, and don’t substitute an essential oil unless its label specifically says it is intended for culinary use and provides safe directions.

Is peppermint syrup the same as peppermint extract?

No. Extract is a concentrated flavoring, while syrup is a sweetened liquid made with sugar and water. The syrup is ready to stir into coffee, while adding extract directly to coffee can produce a strong, uneven flavor without adding sweetness.

How much peppermint syrup should I put in coffee?

Start with 1 teaspoon per 8-ounce cup, then add more if needed. For a latte or mocha, 1 tablespoon is a good starting point. Coffee-shop drinks can be quite sweet, so adjust the amount to suit your taste.

Can I use peppermint syrup in iced coffee?

Yes. Simple syrup dissolves well in cold drinks. Stir it into espresso or a small amount of hot coffee first, then add ice and milk for an evenly flavored iced peppermint coffee.

Can I make the syrup without peppermint extract?

You can infuse the warm syrup with fresh peppermint leaves, then strain them out after steeping. The flavor will be gentler and less consistent than extract, and the leaves need to be removed before storage. For the most reliable result, use peppermint extract.

Why does my peppermint syrup taste too minty?

Extract strengths differ, and peppermint flavor intensifies when there is not much coffee or milk to balance it. Dilute a strongly flavored batch with a little plain simple syrup, or use less in each drink. Next time, begin with ¼ teaspoon extract and add more after tasting.
