Simmer until slightly thickened.
1.Reduce the heat to low once the sugar is fully dissolved.2.Let the mixture simmer gently for 5 minutes, stirring once or twice.3.The syrup will look glossy and should lightly coat the back of a spoon.TIPThe syrup thickens more as it cools, so don't over-reduce it on the stove. - mix

Let the syrup cool in the saucepan for 15-20 minutes until it reaches room temperature. It will continue to thicken slightly as it cools.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a fine-mesh strainer when pouring the syrup to catch any undissolved coffee granules.
- 2Let the syrup cool completely before bottling to prevent condensation from diluting it.
- 3Shake the bottle gently before each use, as vanilla and coffee can settle over time.
- 4For a stronger coffee kick, let the syrup infuse with a whole vanilla bean split open during simmering.
- 5Sterilize your bottle or jar by rinsing with boiling water and air-drying completely before use.
- 6If the syrup crystallizes in the fridge, warm the bottle under hot running water and shake to re-dissolve.
Adapt it for your goals.
Low-sugar
Replace half the granulated sugar with a granulated sweetener like allulose or monk fruit blend for a lower-calorie syrup that still dissolves easily.
vanilla beanVanilla-bean
Substitute vanilla extract with 1 split vanilla bean scraped into the syrup while simmering; steep off heat for 15 minutes before straining for a deeper, speckled vanilla flavor.
spiced coffeeSpiced-coffee
Add 1 cinnamon stick, 3 whole cloves, and a strip of orange zest to the simmering syrup for a chai-coffee hybrid perfect for fall lattes.

No Artificial Additives
Made with just sugar, water, coffee, and vanilla, this syrup contains no preservatives, artificial colors, or high-fructose corn syrup.
Caffeine Kick on Demand
Instant coffee provides a mild caffeine boost, allowing you to customize your energy level per serving without extra brewing steps.
Frequently asked questions
No, brewed coffee adds too much water and can throw off the sugar-to-liquid ratio, making the syrup watery and prone to spoilage.
