In a large bowl, whisk together Biscoff, egg, sugar, and butter. Gently whisk in milk.

In a small bowl, combine flour, baking powder and salt. Pour the dry mixture into the wet mixture, whisking until all is well incorporated.

Lightly butter or grease a large skillet. Place over medium heat and drop batter by the ladle full onto the hot skillet.

Cook until bubbles form and pancakes are golden brown on the bottom. Flip them over and continue cooking for another minute or so.

Stir together topping and serve with crushed Biscoff cookies, if desired.
