Use this recipe for tart dough to make our Cream Puffs.
Put butter and confectioners' sugar in the bowl of an electric mixer fitted with the paddle attachment. Mix on low speed until combined, about 2 minutes. Add egg yolks, and mix until combined, about 1 minute. Add 3/4 cup flour, and mix just until flour is incorporated. Add remaining 3/4 cup flour, the salt, and cream; mix until just combined, about 1 minute.
Shape dough into a disk; wrap in plastic, and refrigerate 2 hours or overnight.
