Preheat the oven according to the directions on the biscuit dough container - either 350 or 375ºF. Place a muffin liner in each muffin well.
In a small pot over medium-low heat, melt the butter, brown sugar and milk, bring to a boil, then remove from the heat.
1/4 cup (57g) melted butter, 1/2 cup (107g) brown sugar, 1/2 Tbsp milk
Cut each biscuit into 4ths or 8ths using a pair of clean scissors. Place the dough in a bowl or ziploc bag. Add the sugar, cinnamon and sprinkles, then cover the bowl or close the bag and shake until the pieces are evenly covered. Add 6-7 biscuit pieces to each muffin well, pressing them together. Pour the cinnamon glaze evenly over each muffin. Bake for 13-17 minutes or until the biscuit pieces are no longer doughy.
Allow the muffins to cool for 10 minutes before removing from the pan. Use a knife to help remove them from the pan.
In a small mixing bowl, use an electric mixer to beat the cream cheese, powdered sugar, milk, and black gel food coloring for 1-2 minutes, or until smooth and completely incorporated. Drizzle the glaze over the monkey bread muffins. Top with additional sprinkles and serve warm.
4 oz (114g) cream cheese, 1 cup (113g) powdered sugar, 1 Tbsp milk, black gel food coloring
