Place 24 frozen dinner rolls in a greased 9x13-inch pan.
Let them thaw and rise according to package instructions, until doubled in size.
In a small bowl, mix together the melted butter, brown sugar, and cinnamon.
Once the dough has risen, gently press fingers into the dough to create focaccia-style dimples.
Pour the cinnamon-butter mixture evenly over the top, letting it fill the dimples.
Bake in a preheated oven at 350°F (175°C) for 20–25 minutes, or until golden brown and cooked through.
Mix powdered sugar with 1–2 tablespoons of milk until smooth.
Drizzle over the warm bread.
Serve warm and enjoy!
