"The tart base is French pie pastry, a pie crust enriched with egg yolks that bakes to a delectable, deep golden brown. It's filled with a combination of peanut butter mousse and chocolate, evoking the flavors of a certain familiar candy. Cream cheese transforms the mousselike filling into an absolutely sublime confection that is perfectly counterbalanced with a layer of silky-smooth bittersweet chocolate ganache. You'll need an 11-inch tart pan with a removable bottom.

The tart can be refrigerated for up to 2 days...."
