1. Spoon hazelnut spread into a 1-qt. heavy-duty zip-top plastic bag (do not seal). Snip 1 corner of bag to make a small hole. Pipe hazelnut spread evenly into Flaky Tartlet Shells. Top each with sweetened whipped cream and a roasted salted hazelnut.
Note: For testing purposes only, we used Nutella for hazelnut spread.
