Pumpkin Pie Spice Simple Syrup Tips and Tricks
How I Make Simple Syrup
Making your own simple syrup at home is as simple as dissolving sugar in water. Typically, when I make plain simple syrup with water and granulated sugar, I use a 1:1 ratio of water to sugar.
However, since we are trying to dissolve a lot of spices into our water and sugar to give this simple syrup a pumpkin spice flavor, we are going to use a little more water than usual.
Add the water, brown sugar, and spice to a saucepan and bring to a boil.

How I Dissolve Sugar and Spice in Water
Once the water mixture is boiling, turn the heat source down so it is lightly simmering. Then, continue to simmer for about 3-5 minutes, whisking occasionally until all of the sugar is dissolved.
It’s important to note that spices will never completely dissolve into water, so our goal is just to mix them in to distribute as evenly as possible and to infuse the syrup with tons of flavor.
This also means that over time, the spices will settle to the bottom of your syrup. Always shake the syrup before use.

How I Store My Pumpkin Spice Syrup
This specialty simple syrup will last for about a month in an airtight container in the refrigerator.
Once your simple syrup is all ready, transfer it to a heat-safe jar with a lid, and allow it to come down to room temperature naturally.
Once it’s room temperature, you can place your jar of simple syrup in the refrigerator for later use. Shake before pouring it in your coffee, tea, or cocktail.

How to Use Pumpkin Spice Simple Syrup
This stuff is liquid gold and transforms any beverage into a festive fall treat!
I use it in cocktails like this Pumpkin Spice Old Fashioned. It’s also the easiest way to make a Pumpkin Spice Latte.
You can also add it to your cold brew, hot coffee, or tea—or even use in place of maple syrup of waffles or pancakes!
