  • 1 can Pillsbury™ Grands! Cinnamon Rolls


  • Preheat oven to 350 degrees.
  • Spritz a ceramic or glass pie plate lightly with cooking spray.
  • Pop open the can of cinnamon rolls, set aside the icing.
  • Place one full cinnamon dough roll in the center of your dish, then one by one unfurl each of the remaining rolls and wrap them around and around until you have one big roll.
  • Bake for 20-25 minutes, covering it lightly with tin foil halfway through.
  • Remove it from the oven when a toothpick inserted towards the center comes out clean. You want the “cake” to be golden but not overcooked so keep an eye on it.
  • Note, do not cook in a metal pan as it browns much faster.
  • Allow “cake” to cool for 3-5 minutes.
  • Place icing in your microwave for 20-30 seconds (NOT with metal lid…I scrape it into a small microwave-safe dish first), use a small whisk; dip it in the icing and drizzle it <g class="gr_ gr_229 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar multiReplace" id="229" data-gr-id="229">overtop</g> your Cinnamon Bun Cake.
  • Cut and enjoy while still warm.
