These convenient handheld mini apple pies takes a few notes from the classic dessert for a delicious modern twist. The favorite childhood vanilla wafer cookie makes a comeback in the form of a crunchy crust. Similar to a graham cracker pie crust, the wafer cookies are crushed and mixed with melted butter to mold into muffin cups. Sour Granny Smith apples are cooked in a skillet on the stovetop and are warmly seasoned with staple fall spices to create the filling. Rich mascarpone becomes delightfully fluffy and when folded into a fresh batch of whipped cream for a decadent pie topper.
