Mile-High Triple-Chocolate-Espresso Mousse Pie
This pie is all about the slow reveal: It appears to be a simple chocolate mousse with a cookie crust. Cut into it, though, and guests will gasp at this triple layered (and flavored!) dessert. Since it's the perfect choice for a special occasion like Thanksgiving or Christmas, we made this icebox creation as make-ahead friendly as possible. Fill and chill up to two days ahead, then dust with cocoa powder before serving.
