Oatmeal with Brown Sugar and Cinnamon

Introduction

Baking quick-cooking oats with brown sugar, cinnamon, milk, butter, and eggs gives you a firm, sliceable oatmeal rather than a spooned porridge. The 40–45 minute bake time sets the center and browns the edges, so you can serve it hot from the pan or chill it and cut it into portions for breakfast through the week.

Recipe Details

• Prep Time: 10 minutes
• Cook Time: 40–45 minutes
• Total Time: 50–55 minutes
• Servings: 8

Ingredients

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

½ cup (120 g) butter (melted)

2 eggs

Instructions

Mix the ingredients and pour them into a 9-inch (20 cm) baking pan. They can also be carefully mixed in the pan.

Bake at 350 °F (175 °C) for 40-45 minutes.

Serve hot, cold, with or without milk.

Variations

• Replace the milk with the same amount of unsweetened oat milk or almond milk if you want a dairy-free version. The baked oatmeal stays tender but tastes slightly less rich.
• Replace the ½ cup (120 g) butter (melted) with the same amount of neutral oil or melted coconut oil. You lose some buttery flavor, but the texture stays moist.
• Replace the quick-cooking oats with old-fashioned oats for a chewier, more distinct oat texture. Expect the center to need a few extra minutes in the oven.
• Replace the 1 teaspoon ground cinnamon with 1 teaspoon apple pie spice if you want a broader spice profile without changing the base recipe.
• After mixing, fold in up to 1 cup of raisins or chopped walnuts. Raisins make it sweeter and softer, while walnuts add crunch.

Tips for Success

• Let the melted butter cool slightly before mixing it with the eggs so the eggs do not start to cook.
• Break up any lumps in the brown sugar before mixing so the sweetness distributes evenly through the pan.
• If you mix directly in the 9-inch (20 cm) pan, scrape the corners well so dry oats and baking powder are fully incorporated.
• Bake until the center looks set and the edges are lightly browned; a wet-looking center needs more time.
• Rest the baked oatmeal for 5–10 minutes before serving if you want cleaner slices.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, cut into portions, wrap tightly, and freeze in a freezer-safe container or bag for up to 2 months.

Reheat individual portions in the microwave for 30–60 seconds from the fridge or until warmed through. For larger portions, cover and reheat in a 325 °F (165 °C) oven for 10–15 minutes. You can also thaw frozen portions overnight in the fridge before reheating.

FAQ

Can you use old-fashioned oats instead of quick-cooking oats?

Yes. The texture will be chewier and less uniform, and the bake may need a few extra minutes to set in the center.

Can you make it ahead?

Yes. Bake it fully, cool it, and refrigerate it; then reheat portions as needed or serve it cold.

Why did the oatmeal turn out dry?

It was likely baked too long or cut while still very hot. Pull it when the center is just set, since it firms up more as it cools.

Can you use a non-dairy milk?

Yes. Unsweetened oat milk or almond milk works in the same amount and keeps the structure intact, though the finished dish will taste a little less rich.
