In a big bowl, combine yeast, milk, and sugar and let it sit for about 10 minutes or until it gets foamy.
¼ ounce instant yeast, 1 cup milk, ½ cup sugar
Add the eggs and butter and combine well. Then add the flour and salt and mix until well combined; it will be sticky, but try to handle it as fast as possible, without touching it too much.
2 eggs, ⅓ cup butter, 4 cups all-purpose flour, 1 teaspoon salt
Transfer the dough to a floured surface and knead it a few times until you can form a big ball. Then transfer the ball to a greased bowl and let it sit until it doubles its size.
Transfer the dough back to a floured surface and extend it with a rolling pin until you get a rectangle of about ⅓ inch thick.
Combine the cinnamon powder and the brown sugar. Spread the butter over the dough and cover it with the cinnamon and sugar filling mixture. Roll it to make a long log. Cut the log in 8 pieces and transfer them to two pieces of parchment paper (4 in each). Let them rise for one more hour.
1 tablespoon cinnamon powder, ½ cup brown sugar, ⅓ cup butter
Preheat your oven to 180ºC/350°F. Place the cinnamon rolls in the oven and bake them for 20-25 minutes, then remove from the oven. Let them cool, and spread the frosting. Serve and enjoy your cinnamon rolls.
