Mix the cinnamon, cardamom, and brown sugar in a small bowl. Rub the surface with melted butter, mix the remaining butter with the cinnamon mixture. The mixture should have the consistency of a paste. Use a spatula to spread the mixture on the dough.
¼ cup Butter
Mix the cinnamon, cardamom, and brown sugar in a small bowl, and spread over the butter.
1 cup Brown sugar, 2 tablespoon Cinnamon, 1 teaspoon Cardamom
Start rolling the dough from the longer side tightly. Now we have a long log. Wet your fingertips to seal the free edge of the log.
Use a serrated knife to cut it into rolls 1-½ inch thick. We will have about 12 to 14 rolls. Place them in the pan or ceramic dish you are baking them in. Cover the rolls and let them proof for 45 minutes, and again they should rise and fill up the pan and the gaps between them.
Preheat the oven to 375℉, and bake the rolls for 20-25 minutes. They will become golden brown when ready.
Leave the cream cheese out of the fridge for several hours beforehand. Use a paddle attachment and beat the cream cheese and the butter. Add the powdered sugar and vanilla extract to the softened cream cheese and butter until well-mixed.
1 cup Cream cheese, ¼ cup Butter, 1½ cup Powdered sugar, 1 teaspoon Vanilla extract
Remove the buns from the oven, spread half of the frosting on them while still warm, let them cool down and spread the remaining frosting over the buns. Cinnabon is best served when warm.
