Mini King Cake Cupcakes

Combine milk, yeast, and 1/4 cup sugar in a bowl. Stir well, and set in a warm place for about 10 minutes. In another bowl, combine butter and next 3 ingredients; stir in 2 teaspoons lemon juice.

Combine flours, 2 teaspoons cinnamon, and kosher salt in a large mixing bowl. Add milk mixture and butter mixture, and beat, adding 1 to 2 tablespoons flour if dough is too sticky, until dough is smooth and forms a shaggy mass. (It should remain soft.)
