Best Tips for Making the Perfect Biscoff Marshmallow Stuffed Cookie

To give your Biscoff stuffed cookie a deeper, nutty flavor, brown the butter before mixing it into the dough. This adds a rich, caramelized taste that complements the sweet Biscoff spread perfectly.

— Chill the Cookie Dough
For the best texture and to prevent excessive spreading, chill the formed dough in the freezer for 15 minutes before baking. This ensures that your single-serve Biscoff cookie stays thick and gooey, especially with that delicious marshmallow-filled center.

— Preheat the Oven
Make sure your oven is preheated to 356°F (180°C) before baking. A properly heated oven ensures your Biscoff marshmallow cookie bakes evenly, with a golden, crisp edge and a soft, marshmallow-filled center.

— Shape Your Cookie If It Spreads Too Much
If your cookie spreads too much during baking, grab a circular cookie cutter and gently shape the warm cookie right after it comes out of the oven. This will help give your cookie stuffed with marshmallow and Biscoff a perfect, uniform shape.

— Use a Cookie Scoop for Even Dough and Filling
For consistent-sized cookies, use a cookie scoop to portion the dough. After scooping, make a small indentation in the center, then add the Biscoff spread and marshmallow filling. Close up the dough around the filling to ensure it stays inside while baking.

— Let the Cookie Cool Before Enjoying
After baking, allow your Biscoff marshmallow stuffed cookie for one to cool slightly before biting into it. This lets the marshmallow center firm up, ensuring it’s not too runny when you take that first bite.
