Food Processor

For extra-fudgy results, make these cakes 1 day ahead; wrap them well in plastic wrap, and refrigerate. Serve them chilled or at room temperature.

Almond flour is simply ground blanched almonds—it doesn’t contain any wheat flour. You can make your own by finely grinding 1/2 cup whole blanched almonds in a food processor. The dough can be refrigerated for up to 2 days or frozen for up to 1 month (thaw before using). The custard filling can be made up to 1 day ahead; press plastic wrap directly onto its surface (to prevent a skin from forming), and refrigerate in an airtight container. This sauce can be made 2 days ahead and refrigerated in an airtight container. Reheat over medium-low heat, or bring to room temperature before serving.

If you are using pasteurized egg whites, you do not need to heat them before beating with the sugar and cream of tartar or coarse salt.

This classic tart, essentially a frangipane filling enclosed between two layers of puff pastry, is named for the French town in which it was created. We recommend using an insulated baking sheet instead of a regular baking sheet to prevent the bottom of the pastry from getting too browned during baking.
