Preparation Phase & Tools to Use
To make this syrup, you’ll need a few essential tools to ensure a smooth and glossy result. A small saucepan is crucial for heating the ingredients gently and evenly. A silicone whisk helps prevent lumps and ensures the cookie butter melts fully into the mixture. Measuring cups and spoons provide precision—key for balancing sweetness and thickness. Lastly, a fine-mesh strainer (optional but helpful) will give you that silky, café-quality finish by removing any undissolved bits.
Preparation Tips
For the best texture, make sure your cookie butter is at room temperature before you begin—it helps it melt faster and combine smoothly. Stir constantly while heating to avoid any scorching at the bottom of the pan. Don’t rush the simmering process; allowing the syrup to bubble gently helps thicken it to the perfect consistency. After cooking, let the syrup cool for 5–10 minutes before transferring it to a jar. This prevents condensation and keeps the texture just right.
Ingredients for this Biscoff Cookie Butter Coffee Syrup
- 1/2 cup Biscoff cookie butter (creamy)
- 1/2 cup water
- 1/2 cup brown sugar (light or dark, based on preference)
- 1/4 tsp ground cinnamon (optional, for enhanced spice)
- 1/4 tsp pure vanilla extract
- Pinch of salt (to balance the sweetness)

Step 1: Combine the Base Ingredients
In a small saucepan over medium heat, combine the water and brown sugar. Stir continuously until the sugar has completely dissolved and the mixture begins to steam but not boil. This forms the sweet base of your syrup.
Step 2: Add the Cookie Butter
Once the sugar is dissolved, lower the heat and stir in the Biscoff cookie butter. Continue whisking until the cookie butter is fully melted and integrated into the liquid. The syrup should appear creamy and golden brown.
Step 3: Enhance the Flavor
Add the ground cinnamon (if using), vanilla extract, and a small pinch of salt. These ingredients help deepen the syrup’s flavor and balance the sweetness. Stir well to combine evenly.
Step 4: Simmer Gently
Let the syrup simmer gently over low heat for 4–5 minutes, stirring occasionally. This helps thicken the mixture slightly and blend the flavors more thoroughly. Do not let it boil vigorously to avoid burning.
Step 5: Cool and Store
Remove the saucepan from heat and allow the syrup to cool for 5–10 minutes. If desired, pour the syrup through a fine-mesh strainer to remove any remaining bits. Transfer to a clean glass jar or bottle with a tight-fitting lid. Store in the refrigerator for up to 2 weeks.
Step 6: Shake Before Use
Before each use, give the syrup a good shake or stir, as natural separation may occur when stored. Drizzle into hot or iced coffee, espresso drinks, or even on pancakes or ice cream for a sweet Biscoff twist.
Notes
This Biscoff Cookie Butter Coffee Syrup is incredibly versatile—use it to add a cozy, caramel-spice twist to nearly any drink or dessert. It works especially well in lattes, frappes, and even cocktails. For a richer flavor, dark brown sugar adds more molasses depth, while light brown sugar gives a subtler sweetness. If your syrup thickens too much after refrigeration, a quick zap in the microwave (10–15 seconds) or a warm water bath can bring it back to pouring consistency.
Watch Out for These Mistakes While Cooking
- Boiling the syrup too hard: This can cause it to burn or separate. Keep the heat low and steady.
- Skipping the whisking: Inadequate stirring can leave clumps of cookie butter or sugar.
- Not using a strainer if needed: If your cookie butter has gritty bits, straining gives a smoother result.
- Over-reducing: Simmering too long will make the syrup overly thick, especially after cooling.
- Using the wrong ratio: Too much sugar can overpower the flavor of the cookie butter.
Storage Instructions
Once fully cooled, transfer the syrup into a clean, airtight glass container. A mason jar or small bottle with a pour spout works perfectly. Store it in the refrigerator for up to 2 weeks. Shake or stir before each use, especially if the syrup has settled or thickened. For longer storage, freeze in ice cube trays and thaw cubes as needed for single-serve portions.
