In a large bowl, whisk together 2 cups of flour, sugar, yeast, baking powder, and salt.

In a separate bowl, combine the warm milk, melted butter, egg, red food coloring, and vanilla extract. Stir this mixture into the dry ingredients, then gradually add the remaining flour to form a soft dough.

On a floured surface, knead the dough for 5-7 minutes until smooth and elastic. Place the dough in an oiled bowl, cover, and let rise in a warm place for about 1 hour, or until it has doubled in size.

For the filling, mix the softened butter, brown sugar, and ground cinnamon together in a small bowl.

Once the dough has risen, roll it out into a 12x18-inch rectangle. Spread the cinnamon-sugar mixture evenly over the dough and sprinkle with mini chocolate chips if desired. Roll the dough tightly into a log and slice it into 12 equal pieces.

Place the rolls in a greased 9x13-inch baking dish. Cover and let rise for another 30 minutes.

Preheat your oven to 350°F (175°C) and bake the rolls for 25-30 minutes, until golden brown.

While the rolls are baking, prepare the cream cheese frosting. Beat the softened cream cheese and butter together until smooth. Gradually add the powdered sugar, vanilla extract, and milk, mixing until the frosting reaches your desired consistency.

Once the rolls are baked and slightly cooled, generously spread the cream cheese frosting over the top.
