Baked Oatmeal: Easy, Healthy Breakfast Recipe with Oats and Cinnamon

Baked oatmeal is a warm, filling breakfast recipe that also works as a snack. This simple dish uses quick-cooking oats, sugar, milk, eggs, butter, and basic baking items. The result is soft, sliceable oatmeal that you can serve hot or cold, with or without milk, for an easy family meal.

This baked oatmeal recipe is less sweet for breakfast, but it can taste like dessert to some people. The texture is firm enough to cut into squares, yet still soft and moist. It is a vegetarian baked breakfast and is useful when you want to prepare oats in advance.

Use these measured ingredients for one 9-inch (20 cm) baking pan of baked oatmeal. Quick-cooking oats are important for the right texture. Brown sugar and cinnamon give a gentle, warm flavour while eggs, butter, and milk help the oats set during baking.

• 3 cups (720 g) quick-cooking oats

• 1 cup (240 g) brown sugar

• 2 teaspoons baking powder

• 1 teaspoon ground cinnamon

• 1 teaspoon salt

• 1 cup (240 ml) milk

• 1/2 cup (120 g) butter, melted

• 2 eggs

  Optional Variation Ingredients

  This baked oatmeal variation uses soy milk and vegetable oil instead of dairy milk and butter. It is still baked in the same way but tastes a little lighter and less rich. You also replace brown sugar with a mix of granulated sugar and molasses.

  • 3 cups (720 g) quick-cooking oats

  • 1/2 cup (120 g) wheat flakes

  • 1/2 cup (120 g) granulated sugar

  • 1 tablespoon molasses

  • 2 teaspoons baking powder

  • 1 teaspoon ground cinnamon

  • 1 teaspoon salt

  • 1 1/2 cups (360 ml) soy milk

  • 1/2 cup (120 ml) vegetable oil

  • 3 eggs

    Equipment Needed

    You only need basic kitchen tools for this baked oatmeal recipe. A standard oven and a 9-inch baking pan are both essential. Simple mixing tools will help you blend the oats, sugar, eggs, and liquids before baking.

    • Oven

    • 9-inch (20 cm) baking pan

    • Medium mixing bowl

    • Whisk or large spoon

    • Measuring cups and spoons

    • Spatula or spoon for serving

      Step-by-Step Procedure

      Follow these clear steps to make baked oatmeal at home. Keep to the oven temperature and time for the best soft yet firm texture. You can mix the batter in a bowl or directly in the greased baking pan to save washing up.

      1. Heat your oven to 350 °F (175 °C). Lightly grease a 9-inch (20 cm) baking pan with a little butter or oil so the baked oatmeal does not stick.

      2. In a mixing bowl, add oats, brown sugar, baking powder, cinnamon, and salt. Stir these dry ingredients until the mixture looks even and the cinnamon is well spread.

      3. In another bowl, whisk the milk, melted butter, and eggs until smooth. Make sure the butter is warm, not hot, so it does not start to cook the eggs while mixing.

      4. Pour the wet mixture into the bowl with the oats and sugar. Stir well until all the oats are coated and no dry patches of oats or sugar remain in the bowl.

      5. Transfer the mixture to the greased baking pan. Spread it into an even layer with a spoon or spatula so it bakes at the same rate across the whole pan.

      6. Place the pan in the heated oven. Bake at 350 °F (175 °C) for 40 to 45 minutes, until the top looks set and lightly golden and the centre is no longer wet.

      7. Remove the baked oatmeal from the oven and let it cool for a few minutes. Cut into squares and serve hot or cold, with milk or without milk, as you like.

      How to Serve Baked Oatmeal

      You can eat baked oatmeal straight from the pan while it is hot and soft. For a firmer texture that holds its shape, let it cool more before cutting. Many people like to pour a little milk over each serving, but it is also fine plain.

      Notes, Tips, and Variations

      The soy milk and vegetable oil version works well for people who avoid dairy. It also uses wheat flakes for extra texture. You can serve any version warm for breakfast or cool as a snack bar, which is handy for busy mornings and school tiffin.
