A few tablespoons Biscoff spread(creamy or chunky)
Toss the frozen banana slices into a blender or food processor and puree until smooth. Add the Biscoff spread, to taste, and pulse until evenly swirled in. Alternatively, you can just stir in the Biscoff spread with a spoon. Serve immediately.
*Recipe Note: To freeze the bananas, cut into 1-inch slices, then freeze in a single layer on a parchment or wax paper lined baking sheet for 2 hours. Transfer to a freezer bag and store until ready to use. This method keeps the banana slices from sticking together, which helps to puree more evenly.
