Preheat oven to 350°F and grease a bundt pan thoroughly.

Cut Hawaiian rolls into small cubes and place in a large bowl.

Whisk together eggs, brown sugar, butter, 1/3 cup milk, and cinnamon in a small bowl.

Pour half the mixture over the cubed bread and gently toss to coat.

Transfer bread to the bundt pan and pour remaining mixture over the top.

Bake for 22–24 minutes until golden and edges are crisp.

Let cool for 3–5 minutes. Loosen edges with a knife and invert onto a plate.

Mix 1 tbsp milk with powdered sugar to form a glaze and drizzle over cake.

Serve warm or at room temperature.
