Ingredients for tiramisu coffee syrup

Sugar: This is what forms the base of the syrup and gives it that classic sweet, pourable texture. It dissolves into the hot water and helps carry all the coffee and cocoa flavor through every sip.
Water: The hot water is what brings everything together. It dissolves the sugar and helps melt the cocoa, espresso, and butter into a smooth, rich syrup.
Instant espresso: This is where the coffee flavor comes from. It gives the syrup that bold, slightly bitter edge that balances out the sweetness and makes it taste like tiramisu.
Cocoa powder: Adds that subtle chocolate note that ties everything together. It deepens the flavor and gives the syrup its dessert-like richness.
Coconut sweetened condensed milk: This adds creaminess and a light caramel-like sweetness. It helps round out the flavor so it feels more like a dessert syrup than just coffee sugar.
Dairy-free butter: This adds a little richness and smoothness to the syrup. It melts into the hot mixture and gives it a slightly more decadent, café-style finish.
Vanilla extract: Adds warmth and depth and helps bring out the dessert-like flavor in the syrup.
Rum extract: This gives it that classic tiramisu-inspired flavor without any alcohol. It adds a slight warmth and depth that makes the syrup feel more authentic.
Flaky salt: Just a pinch helps balance the sweetness and makes the coffee and chocolate flavors stand out more.

How to make tiramisu coffee syrup

In a large glass measuring cup or jar, add the sugar, instant espresso, cocoa powder, coconut sweetened condensed milk, dairy-free butter, and a pinch of flaky salt.
Microwave the water for about 2 minutes until very hot. Pour the hot water over the mixture and stir well until the sugar is fully dissolved and the butter is melted into the syrup.
Let the mixture cool slightly, then stir in the vanilla extract and rum extract. Adding them after cooling helps keep the flavor strong and balanced.
Once completely cooled, transfer to a bottle or jar and store in the fridge.

Tips for making coffee syrup

Make sure everything is well stirred while the mixture is still hot so the cocoa and espresso fully dissolve.
The dairy-free butter helps give it a slightly richer, smoother texture, don’t skip the whisking step so it fully blends in.
Add the extracts after it cools slightly so they don’t lose their punch.
Let it chill completely before using so it thickens a bit and the flavors develop.
