How to Bake Thaw Cinnamon Rolls overnight in the fridge. Preheat the oven to 375 degrees. Unroll the first ring of the Cinnamon Roll and detach from the rest of the roll by cutting with a knife. Cut the detached dough strand into two pieces and use to form two ears on top of the remaining Cinnamon Roll. Once all formed, place on a baking sheet in the oven for 18-25 minutes or until golden brown. Warm the provided icing packet in a cup of hot water and then slather each bunny roll. Top the "face" of each bunny with a miniature chocolate chip for eyes. Enjoy!
