Activate the Yeast: In a medium bowl, dissolve the yeast in 1 cup of warm milk (approximately 110°F) and let it stand for about 5 minutes until frothy.

Mix Dry Ingredients: In a large mixing bowl, combine 4 cups of flour, 1/2 cup of sugar, and 1 teaspoon of salt. Whisk together until evenly mixed.

Combine Wet Ingredients: Carefully add the melted butter, 2 eggs, and the yeast mixture to the dry ingredients. Mix using a wooden spoon until a dough begins to form.

Knead the Dough: Flour your work surface and knead the dough for about 5-10 minutes until it’s smooth and elastic.

First Rise: Place the dough in a greased bowl, cover with a damp cloth, and let it rise in a warm place for about 1 hour, or until it has doubled in size.

Roll Out the Dough: Gently punch down the risen dough and roll it out into a rectangle about 1/4 inch thick.

Add the Fillings: Spread 1 cup of marshmallow fluff evenly over the dough, then sprinkle 1 cup of chocolate chips on top.

Shape the Rolls: Starting from the long edge, roll the dough tightly into a log. Slice the log into 12-15 rolls.

Second Rise: Place the rolls in a greased baking pan, cover, and let them rise again for about 30 minutes until puffy.

Bake: Preheat your oven to 350°F (175°C). Bake the rolls for 20-25 minutes or until they are golden brown on top.

Make the Icing: In a small bowl, whisk together 1/2 cup of powdered sugar, 2 tablespoons of cocoa powder, and 1-2 tablespoons of milk until smooth.

Drizzle Icing: Once the rolls are cool, drizzle the icing over the top.
