1Pour 1 cup of warm milk (approximately 110°Fahrenheit) into a large mixing bowl.
2Add 1 packet or 2 and 1/4 teaspoons of yeast to the warm milk.
3Let the yeast and milk mixture sit for about 5 minutes until it looks foamy.
4Add 1/3 cup of melted and cooled salted butter to the foamy mixture.
5Add 1/2 cup of sugar to the mixture.
6Crack and add 2 room-temperature eggs to the mixture and break them up with a whisk.
7Add 1 teaspoon of salt to the mixture.
8Add 4 cups of bread flour (scooped and fluffed, not packed) to the mixture.
9Cover the bowl with a towel and let the mixture sit for another 5 minutes to soak up all the liquid.
10Attach the dough hook to your mixer.
11Knead the dough on low speed for about 5 minutes until it's stretchy and soft.
12Spray the mixing bowl with oil and place the dough into it.
13Cover the bowl with a towel and let the dough rise until it doubles in size.
14While the dough is rising, prepare the filling by combining 1/2 cup of softened butter, 2 tablespoons of cinnamon, and 1 cup of packed brown sugar in a separate bowl.
15Mix the filling ingredients until they are combined and cohesive.
16Lightly dust a clean surface with flour.
17Roll out the risen dough into a large rectangle.
18Evenly spread the cinnamon-brown sugar filling over the entire surface of the dough.
19Starting from one end, tightly roll the dough into a log.
20Using a sharp knife, cut the log into 12 equal rolls.
21Use the softened butter wrapper from earlier to grease a 9x13 baking dish.
22Place the cut cinnamon rolls into the greased baking dish, swirl side up.
23Cover the dish with a paper towel and let the rolls rise again while the oven preheats to 375°Fahrenheit.
24Once the oven is preheated, pour 1/2 cup of heavy cream over the risen cinnamon rolls.
25Bake the cinnamon rolls in the preheated oven for 25 minutes.
26While the rolls are baking, prepare the frosting by combining 1 stick of softened butter and 1 brick of softened cream cheese in a mixing bowl.
27Beat the butter and cream cheese until they are combined.
28Add 1/2 teaspoon of maple extract (or a squirt of maple syrup) and 1 teaspoon of vanilla extract to the frosting mixture.
29Add about 2 cups of powdered sugar to the frosting mixture.
30Beat all the frosting ingredients until smooth.
31Once the cinnamon rolls have cooled slightly after baking, spread the prepared frosting evenly on top.
32Serve and enjoy your copycat Cinnabon cinnamon rolls.
