On a lightly floured surface, unroll piecrusts. Using a 2½-inch round cutter dipped in flour, cut 24 rounds. Press rounds into 24 miniature muffin cups.
In a large bowl, beat cream cheese, zest, and vanilla with a mixer at medium speed until creamy. Add sugar and orange juice, and beat until combined. Add egg; beat at low speed just until combined. Divide mixture among prepared crusts (about 2 teaspoonfuls each).
Bake until filling is puffed and crust is lightly browned, about 15 minutes. Let cool on wire racks for 15 minutes. (Filling will deflate as it cools.) Run a knife around edges of cups to loosen tarts. Gently remove, and let cool completely on wire racks. Refrigerate until chilled.
In a large bowl, beat cream, confectioners’ sugar, and orange liqueur with a mixer at medium speed just until sti peaks form. Spoon onto tarts. Garnish with orange slices, if desired.
Notes
*We used Grand Marnier. Orange juice may be substituted, if desired.
