If you’re a coffee lover who also secretly snacks on cookie butter by the spoonful, this Biscoff Cookie Butter Coffee Syrup is about to become your new obsession. It transforms your morning cup into a cozy, indulgent experience with warm notes of caramelized spice and creamy richness that only Biscoff can bring.

Made with just a handful of ingredients and ready in minutes, this syrup is perfect for lattes, iced coffee, cold brews, or even drizzled over pancakes and desserts. It stores beautifully and makes a fantastic edible gift, too.

The classic Lotus Biscoff spread is my go-to for this syrup, thanks to its smooth texture and deep spiced caramel flavor. You can also use any creamy cookie butter brand you love, just make sure it’s smooth for easy mixing.

1/2 cup water
1/2 cup brown sugar
1/3 cup Biscoff cookie butter
1/2 tsp vanilla extract
Pinch of salt

Step 1: Combine the Base

In a small saucepan over medium heat, combine the water and brown sugar. Stir until the sugar fully dissolves and the mixture is gently simmering.

Whisk in the Biscoff cookie butter until the mixture is completely smooth and integrated. Keep stirring so nothing sticks to the bottom.

Step 3: Flavor Boost

Stir in the vanilla extract and a pinch of salt. Let the syrup simmer for another minute, then remove it from the heat.

Step 4: Cool and Store

Allow the syrup to cool slightly, then pour it into a clean jar or bottle. Store in the refrigerator for up to 2 weeks. Shake before each use.

How to Serve and Store Your Syrup

This syrup pairs beautifully with hot or iced coffee, but it’s also delicious in milkshakes, on top of ice cream, or mixed into cocktails. For storage, keep it in an airtight container in the fridge. It may thicken slightly when cold, but a quick stir or gentle warming will bring it back to pourable.
