Chocolate cream stacks

Our version of this classic is updated and brightened with freshly grated orange zest and turned into fun-to-eat stacks. Thanks to store-bought chocolate wafers you can whip these show-stopping treats up without turning on your oven. These easily double to feed a crowd. For a pretty presentation, top each stack with a few thin slices of strawberry and a mint leaf just before serving. We recommend assembling and chilling them up to 4 hours in advance. But if you need a bigger jump-start you can make the filling 2 to 3 days ahead and then make the stacks the day you plan to serve them.
