Fans of Dutch apple pie will find their true love in this variation, which brings the classic spiced snickerdoodle cookie to the delicious buttery crumb topping and crust. A mixture of flour, sugar, cinnamon, salt, cream of tartar, butter and apple cider vinegar make up the essential cookie crumb base. The filling is a luscious blend of Granny Smith apples, sugar, flour, cinnamon and sea salt. When the two come together and bake up golden, be sure to have plenty of vanilla ice cream to go around and melt over rich slices of this incredible marriage of fall dessert flavors.
