We take your grandma’s cinnamon buns to a whole new level by adding a butter tart filling. Gorgeous buns are baked in a sweet mess, so when they’re flipped, they drip with butter tart goodness. You’re welcome!

3. Add in butter and eggs and stir to combine. Add in flour, 1 cup at a time until a soft, pliable dough forms. If dough is tacky, continue adding flour until smooth.
