This frosting is a Biscoff lovers dream. A smooth buttercream infused with Biscoff spread. It only uses 4 simple ingredients, can be made in under 5 minutes and is super simple to make!
Start by making a basic buttercream frosting. Cream the unsalted butter until soft, this usually only takes 1-2 minutes. Next, add the icing sugar in two batches along with the milk. I would recommend stirring it through lightly with a spoon before blending it together, just to stop an icing sugar explosion! When this basic buttercream has been made it’s time to add in the spread. Simply stir the spread through the buttercream, again adding more or less to taste. Blend everything together until fully incorporated and you have a nice smooth frosting.

The buttercream frosting icing in this recipe is thick enough to hold its own shape which makes it perfect for piping. Once ready and iced place a biscuit on top of each cake, you may need to break it up a little in order to fit on top, for the perfect finishing touch.
I love to place this on top of my Biscoff cupcakes for the ultimate Biscoff treat. To finish it off, top with a biscuit for the ultimate indulgence!
