How-to Make a Heart-Shaped Coffee Cake
Roll dough into a 15-in. x 10-in. rectangle. Brush with melted butter. Spread filling to within 1/2 in. of edges. Roll up jelly-roll style, starting with a long side; pinch seams to seal. Fold roll in half with seams touching, making top half 1-1/2 in. longer than bottom half. Place on a greased baking sheet.
Start at the folded end, cut lengthwise down the middle with scissors to within 1-1/2 in. of open ends.
Turn each side so that the cut side is up and shape into a heart. Tuck pointed end of heart under.
