Biscoff Buttercream

This silky smooth biscoff buttercream is a cookie butter lover’s dream. The warm spiced, caramelized brown sugar and cinnamon flavors tastes like the classic lotus biscoff cookies in frosting form. This 4 ingredient, 5 minute recipe is going to have you practically drooling!

This rich biscoff frosting is made with a simple American buttercream base. It uses a hefty portion of cookie butter so it’s bursting with notes of ginger, nutmeg, cloves, and cinnamon and goes well with so many different desserts!
I use this buttercream recipe in my biscoff cookie layer cake, but the flavors taste amazing with other types of cakes, cupcakes, and even cookies! And hey – no one here will judge if you just want to eat the buttercream by itself with a spoon ;P

What Desserts To Pair With Cookie Butter Buttercream
- Use this frosting instead of the vanilla buttercream on top of these super soft sugar cookies (you’ll need one third of the amount of buttercream in this recipe)
- You can also pair biscoff buttercream with my small batch chocolate cupcakes (you can use half of this recipe).
- I personally LOVE adding buttercream frosting on top of brownies, blondies, and bars.
Ingredient Notes
- Butter: This recipe has been tested with both dairy butter and dairy free butter and works seamlessly both ways. Just be sure the butter is soft!
- Lotus Biscoff Cookie Butter Spread: Ideally the smooth kind (unless you want that crunch factor), and it can be any brand! Trader Joes (they label it as speculoos cookie butter), President’s Choice, and even Walmart all make their own brands of this heavenly spread.

Recipe Developer Tip
Adjust the consistency of the buttercream as you see fit!
If the buttercream is too thin, add in a bit more powdered sugar, around 1/8 cup at a time. Mix then test again between each addition.
If the buttercream is too thick, you can add in 1-2 Tablespoons of milk at a time. Mix again and continue until the consistency is right for you.
When I was testing the recipe, it was slightly thicker with dairy butter than it was with most dairy free butters, so it can vary depending what you choose to use!
