5-Minute Biscoff Cookie Milkshake
A thick, creamy Biscoff cookie milkshake that tastes like spiced speculoos cookies spun into something cold and sippable. It needs just five ingredients and about five minutes, which makes it an evening hack you’ll reach for when the cookie butter jar is calling your name.
What Makes This Shake So Good
The caramelized brown sugar notes of Biscoff cookies already feel like dessert. Blending them with cold vanilla ice cream turns that warm spice into a refreshing drink without losing any of its toasted, gingery depth.
A big spoonful of cookie butter folded into the mix gives the shake a silky body and a hit of that same spice, so every sip tastes like the cookie itself. It is not overly sweet, just rich and smooth enough to feel like a proper treat.
Ingredients
- 4 Biscoff cookies, plus 1 extra for topping: the speculoos shortbread makes the whole thing taste like the cookie at the base.
- 1 heaping tbsp Biscoff cookie butter spread: brings the caramelized spice and keeps the shake luscious.
- 2 cups vanilla ice cream: use full-fat for the creamiest texture.
- ⅓ cup whole milk: helps the blender move things around without thinning it too much.
- ½ tsp vanilla extract: a background note that deepens the warm spice.
- Pinch of fine sea salt: a tiny bit pulls the sweetness into focus.
Variations / Substitutions
- Swap the milk: oat milk or any creamy non-dairy milk works, though whole milk gives the richest result.
- Dairy-free version: use a thick plant-based vanilla ice cream and skip the cookie butter or use a Biscoff-style spread that suits your diet.
- Chocolate twist: swap the vanilla extract for ¼ tsp cinnamon and drizzle chocolate syrup inside the glass before pouring.
- Extra crunch: pulse a few toasted almonds in with the cookies for a nutty speculoos shake.
How to Make a Biscoff Cookie Milkshake
Step 1: Blend the Milkshake
Add the 4 Biscoff cookies, 1 heaping tablespoon of cookie butter, 2 cups of vanilla ice cream, ⅓ cup whole milk, ½ teaspoon vanilla extract, and a pinch of salt to a blender. Blend on medium speed for 20 to 30 seconds, just until the cookies are broken down and the mixture looks smooth and thick.
Step 2: Thin It Out
Pour the shake into a glass and check the consistency. If you like an extra thick shake, it is ready. To loosen it slightly, stir in another tablespoon of milk and press it through with a spoon rather than blending again, which would warm the ice cream.
Step 3: Pour and Garnish
Pour the finished shake into a chilled glass. Crush the extra Biscoff cookie over the top so little specks and larger crumbles sit on the creamy surface, then drizzle a thin thread of cookie butter right over the crumbles and serve immediately.
Tips for a Smoother Shake
- Chill the glass: for ten minutes in the freezer before you start. A cold glass keeps the shake thick a little longer.
- Use whole cookies, not crumbs, in the blender. The small cookie pieces will break down into tiny speckles that distribute the spice without turning sandy.
- Don’t overblend.: The motor’s friction can melt the ice cream quickly, so stop as soon as the shake looks uniform.
Scale it to your cup size:
| Glass size | Milk | Ice cream | Cookies | Cookie butter |
|---|---|---|---|---|
| 8 oz | 3 tbsp | 1 ¼ cups | 3 | 2 tsp |
| 12 oz | ⅓ cup | 2 cups | 4 | 1 heaping tbsp |
| 16 oz | ½ cup | 2 ¾ cups | 5 | 1 ½ tbsp |
Frequently Asked Questions
Can I make this with a different cookie?
Yes, but the whole point is the warm, spiced flavor of speculoos. Gingersnaps are the closest match, while graham crackers will taste much milder.
How do I make it even thicker?
Scoop the ice cream and freeze the balls for an extra 15 minutes before blending, and use only ¼ cup of milk. Pulse instead of running the blender continuously so the mixture stays cold and dense.
Can I skip the cookie butter?
You can, but the shake loses its signature depth and a lot of its creamy texture. If you must, add an extra Biscoff cookie and a small spoonful of brown sugar to bring back some of that toasty note.
Is there a way to prep this ahead?
Milkshakes separate and melt quickly, so there is no way to store it once blended. You can measure the cookies, milk, and cookie butter into a jar the night before, then dump it into the blender with the ice cream when you are ready.
