Why you’ll love this recipe
- Authentic Biscoff flavour: All the toasted, caramel spice of cookie butter transformed into a smooth, pourable sauce that won’t seize.
- Versatile dessert topping: Drizzle it over vanilla ice cream, stir into warm porridge, coat cheesecake sticks or spoon it onto pancakes for an indulgent breakfast.
- Fast and foolproof: Only three ingredients and about five minutes from start to finish—perfect for last-minute cravings.
Ingredients
- Lotus Biscoff spread: Smooth spread gives the creamiest, most pourable sauce; use crunchy if you prefer added texture.
- Milk: A little milk thins the spread to a sauce consistency. Full-fat dairy milk gives the richest flavour; use your favourite plant-based milk for a dairy-free version (flavour may vary slightly).
- Fresh lemon juice: A splash balances the sweetness and brightens the sauce—freshly squeezed works best.
How to make Biscoff sauce
See the recipe card at the end for exact ingredient amounts and step-by-step instructions.
Start by juicing the lemon. Warm the milk gently—either briefly in a microwave-safe bowl or in a small saucepan—until just warm, not boiling. Add the Biscoff spread to the warm milk and whisk until smooth and lump-free. Stir in the lemon juice and whisk again until fully combined. Serve warm straight away for a pourable sauce, or let it cool slightly for a thicker topping to spoon over chilled desserts.
Hot tip: A whisk is the easiest way to get a smooth, lump-free sauce quickly. If the sauce is too thick, add a splash more warm milk until you reach the right pourability.
How to serve
Drizzle warm Biscoff sauce over a scoop of vanilla ice cream, spoon it on top of cheesecake or cheesecake sticks, pour it over pancakes or waffles, or use it as a dip for fruit. It’s also delicious swirled into plain yogurt or warmed custard for an instant flavour upgrade.
How to store
Refrigerate: Store leftover sauce in a covered container in the fridge for up to five days. Reheat gently—either in short bursts in the microwave or over low heat—stirring frequently to bring it back to a smooth consistency. If it separates after overheating, let it cool slightly and whisk until it recombines.
Tips for success and frequently asked questions
Can I use a different brand of speculoos spread?
Yes—any speculoos or cookie-butter style spread will work. Brands vary slightly in sweetness and texture, so you may need to adjust the milk amount to get the right consistency.
Can I make this dairy-free or vegan?
Absolutely. The Biscoff spread itself is typically dairy-free. Substitute your preferred plant-based milk (oat, almond, soy, etc.) and proceed as usual.
My sauce isn’t pouring — what should I do?
Warmth affects pourability. If the sauce has cooled and thickened, gently reheat and stir, or whisk in a little warm milk until it loosens up.
My sauce has split — any fix?
If it separates after overheating, remove from heat, let it cool slightly, and whisk vigorously. The sauce should come back together once it returns to a moderate temperature.
