Biscoff Sandwich Cookies

Biscoff Sandwich Cookies feature oatmeal-based cookies with a creamy Biscoff spread and butter filling. The dough blends cookie butter with sugars, oats, and leavening agents for a tender, slightly chewy texture. After baking, sandwiches are assembled with a smooth Biscoff frosting lightened by heavy cream, and sweetened with confectioners sugar.
