                Fold the dry ingredient mixture into the creamed butter mixture to form a thick, even dough.
              
              
              
                06 - 
                Gently stir in finely chopped white chocolate to distribute it evenly throughout the dough.

                Using a cookie scoop, portion the dough into evenly sized balls. Work swiftly to prevent the dough from warming.

                Flatten each dough ball, place a frozen Biscoff scoop in the center, then wrap and seal the dough tightly around the filling. Roll back into a ball.

                Line baking trays with parchment paper. Space cookies evenly, no more than six per tray, to allow spreading during baking.

                Bake in a preheated oven at 190°C (170°C fan) for 11 to 13 minutes until edges are set but centers remain soft and gooey.
              
              
              
                11 - 
                Allow cookies to rest on the baking tray for 5 minutes to set the molten centers. Serve warm for optimal gooey texture.
