If needed, you can bake these miniature rolls in batches--just refrigerate any extra dough while you wait to refill the pans.
Prepare roll mix according to package directions. Divide dough into 2 equal portions. Roll 1 portion of dough into a 12- x 8-inch rectangle on a lightly floured surface. Spread with 2 Tbsp. butter.
Stir together granulated sugar and next 2 ingredients; sprinkle half of sugar mixture over butter on dough rectangle. Roll up rectangle, jelly-roll fashion, starting at 1 long side. Repeat procedure with remaining dough, butter, and sugar mixture.
Cut each roll into 1/2-inch slices, and place slices in cups of 4 lightly greased 12-cup miniature muffin pans. Cover and let rise in a warm place (85°), free from drafts, 20 minutes.
Preheat oven to 375°. Bake rolls 10 to 12 minutes or until golden. Remove from pans to wire racks, and let cool 5 minutes.
Stir together powdered sugar and orange juice until smooth; drizzle over tops of rolls.
