Banana Biscoff Smoothie

If you’re a Biscoff lover like me, this oatmeal banana Biscoff smoothie is the perfect snack. It tastes like a spiced oatmeal cookie in a glass (which is definitely something I can get behind!). Biscoff spread (also known as cookie butter) is whirled with sweet ripe banana, milk, oats, Greek yogurt, and more for a sweet, crave-able smoothie.

Not only is it delicious, but it also has nutrients from the banana, oats, and Greek yogurt. And don’t worry: if you don’t have Biscoff spread, you can still make this.

Biscoff Oatmeal Smoothie

My husband is a smoothie fanatic, and he’s turned me into one too! They’re such a satisfying afternoon snack, and so easy to make. We always have a bag of frozen banana pieces prepped and ready for when the craving strikes. 🙂

After I discovered Biscoff spread earlier this year, I knew I wanted to find as many ways to enjoy it as possible. Hence, the idea for this smoothie! (If you love Biscoff too, check out these no bake mini biscoff cheesecakes. They feature crushed Biscoff cookies in the crust and in the filling!).

This Biscoff smoothie is creamy and flavorful, and only takes 5 minutes to whip up. The only advance preparation you need is to chop up and freeze a banana. (And if you forget, it’s no big deal – you can always add more ice to thicken up the smoothie.)

What is Biscoff spread (also known as cookie butter)?

Biscoff – or Speculoos – is a type of biscuit-like cookie that originated in Belgium.

Biscoff spread/cookie butter is a spread made from crushed Biscoff cookies. It’s a bit like nutella, but a little thicker and with a different flavor, of course. The flavor of Biscoff is warm and spiced, sort of like caramelized gingerbread and/or chai spice.

What if I don’t have any cookie butter? Can I still make this? Yes, you can! If you have Biscoff cookies, you can make your own homemade Biscoff spread. Or, if you don’t have those, use spices from your pantry for a homemade Biscoff spice blend.

Recipe Ingredients

Here’s what you’ll need to make this smoothie:

  • Biscoff spread/cookie butter: The highlight of this smoothie! It brings a lightly caramelized, warm-spiced flavor to the smoothie, and adds sweetness.
  • banana: A frozen banana adds sweetness (especially if it’s super ripe!) and gives the smoothie texture.
  • oats: These help thicken the smoothie, and give it that hint of oatmeal cookie flavor. I used old-fashioned/rolled oats here, but quick oats should also work.
  • milk: This is necessary for blending the ingredients. Without it, your smoothie will be too thick and won’t blend properly. You can use dairy-free or plant-based milk, just be aware it may change the flavor of the smoothie.
  • Greek yogurt: For added tang and creaminess (plus protein!).
  • vanilla extract: This isn’t essential, but I love adding vanilla extract to smoothies. I find it really rounds out the flavor.
  • cinnamon: To accentuate the Speculoos/Biscoff spices.
  • salt: Just a pinch to compliment the flavors and sweetness.
  • ice: Optional, for thickening the smoothie’s texture if desired. (Or if you don’t have a banana that’s frozen).

Banana Biscoff Smoothie Making Tips

Here are some tips for making the best Biscoff smoothie:

  • Slice bananas into chunks before freezing so they’ll fit in your blender.
  • If you don’t have a banana that’s frozen, you can add a handful of ice to thicken (and chill) the smoothie. (The flavor will just be a bit more muted).
  • For a more intense Biscoff flavor, add an additional tablespoon of Biscoff spread.
  • If you don’t like the texture of blended oats in smoothies, pulse the oats on their own first into a fine powder before adding the rest of the ingredients and blending again.
  • Different types of Biscoff spread/cookie butter have different levels of added sugar. For example, the Trader Joe’s version is less sweet than the one I used. You may want to add maple syrup to taste, depending on how sweet you want your smoothie.

Topping Ideas & Add-Ins

I topped mine with cinnamon and sliced bananas, but feel free to do it up however you like! Shredded coconut or additional crushed Biscoff cookies would be great mix-ins.

You can also stir in a spoonful of chia seeds or flax seeds for added nutrients, or throw in a handful of chocolate chips before blending.

For the love of all that is tasty, you need to try this smoothie! 🙂

Love that Biscoff flavor? Try this Biscoff mug cake or these no bake mini Biscoff cheesecakes (made with Biscoff cookies). These Biscoff tiramisu cups are delicious, too!

  • 1/4 cup plain Greek yogurt

Notes

Helpful Tips:
  • Slice your banana into chunks before freezing. That way, it’ll fit easier in your blender. If you only have a whole frozen banana, place it in a zippable plastic bag and crush it into pieces with a rolling pin or other heavy object.
  • If you don’t have a banana that’s frozen, you can add a handful of ice to thicken (and chill) the smoothie. (It’ll just be slightly less flavorful).
  • For a more intense Biscoff flavor, add an additional tablespoon of Biscoff spread.
  • If you don’t like the texture of blended oats in smoothies: pulse the oats on their own before adding any other ingredients. Once they’re a fine powder, add the rest of the ingredients and blend again.
  • Different brands of cookie butter have different levels of added sugar. For example, the Trader Joe’s version has less sugar than the one I used (Nuccina). You may want to add maple syrup to your smoothie (to taste), depending on how sweet you want it.

    1. I would use less – probably 2 teaspoons. It won’t taste exactly the same (and I would maybe add some maple syrup for sweetness), but I think it should work in a pinch. 🙂 I haven’t tested it yet, though!
