  • 6 cups water
  • 2 cups steel cut oats
  • 2 cups half-and-half or cream
  • 2-3 tablespoons light brown sugar (maybe more to taste)
  • 1 teaspoon cinnamon (maybe more to taste)
  • 1 teaspoon kosher salt (maybe more to taste)
  • 4 tbsp unsalted butter


  • Bring water to a boil. Add oats and stir gently. Bring back to a boil and then turn down to a low simmer.
  • Stir in half-and-half or cream. Add brown sugar, cinnamon, salt, and butter. Stir occasionally.
  • Cook for about 45 minutes, until oats are tender and thickened. Taste and adjust seasonings accordingly. Allow oatmeal to cool for about half an hour.
  • Spray muffin tins with cooking spray. Scoop oatmeal into muffin tins, filling completely. Place muffin tins uncovered in freezer for several hours until oatmeal is completely frozen. You can leave overnight.
  • The oatmeal muffins should just come right out when you pull at them, but if not you may need to run a little hot water on the underside of the pan.
  • Wrap each oatmeal muffin in freezer paper and place in a large zipper storage bag.
  • To serve, unwrap oatmeal and place in microwave-safe bowl. Add a tablespoon or two of milk or water if you like oatmeal a little less thick. Zap 1-2 minutes, stirring halfway through.
