Store-bought apple butter pulls double duty in these marvelous morning buns: it's spread onto the dough before rolling, and it's simmered with brown sugar and butter for the sticky-sweet glaze. Toasted pecans and dried currants scattered throughout add just the right amount of texture.
Rolls can be made, sliced, and frozen up to 3 months ahead. Freeze them in their baking dish, tightly wrapped in plastic, at the end of step 3. When ready to proceed, defrost them in the refrigerator overnight before continuing with step 4.
