You have chosen to make Cinnamon Roll Bread Pudding.
Cube up remaining cinnamon rolls.
Whisk together 2 eggs and 1/2 cup of whole milk per two cups of cubes. Add a teeny pinch of salt. Butter a dish that will accomodate your cubes.
Place cubes in dish.
Pour egg mixture over cubes. Press down. Soak for 15 minutes. Bake at 400 until almost completely set, just a bit jiggly in the center. Cooking time depends on the size of your pan. Check it at 20 minutes.
Cut yourself a slice. Or just dive in with a fork. You’re among friends here. Also, you’ve earned it.
