# Cozy Baked Oatmeal

Baked oatmeal is warm, cinnamon-spiced oats baked with fruit until golden and set. It slices like a soft breakfast cake and tastes like oatmeal cookie meets porridge.

Bake it once on the weekend and breakfast is ready for days.

## Ingredients

- 2 cups (180 g) old-fashioned rolled oats
- 1/3 cup (65 g) brown sugar
- 1 1/2 tsp baking powder
- 1 tsp cinnamon
- 1/2 tsp salt
- 1 1/2 cups (360 ml) milk
- 1 egg
- 3 tbsp butter, melted
- 1 tsp vanilla extract
- 2 ripe bananas, sliced
- 1 cup blueberries or chopped apple
- 1/3 cup chopped walnuts or pecans

## Method

1. Heat the oven to 375°F (190°C) and grease an 8 inch (20 cm) square baking dish.
2. Layer half the banana slices on the bottom of the dish.
3. Mix the oats, brown sugar, baking powder, cinnamon and salt in a large bowl.
4. Whisk the milk, egg, melted butter and vanilla in a second bowl, then pour into the oat mix and stir.
5. Fold in the blueberries and half the walnuts.
6. Pour the mix over the bananas and spread evenly. Top with the remaining banana slices and nuts.
7. Bake 30 to 35 minutes, until the top is golden, the edges pull away from the dish and the center is set when lightly pressed.
8. Cool 10 minutes, then scoop or slice. Serve warm with milk or yogurt.

## Why it works

- Baking powder lifts the oats slightly so the bake is tender, not dense.
- One egg binds the mix so it sets into sliceable squares.
- Mashing or layering banana adds natural sweetness and moisture, so you need less sugar.
- Butter adds richness and helps the top brown.
- Resting for 10 minutes after baking lets the oats finish absorbing liquid so it holds together.

## The science

- **Oats absorb as they bake.** Rolled oats are dry flakes of starch and fiber. In warm milk, the starch granules swell and soften, and the egg proteins set around them. This turns a loose mix into a custardy bake that holds a slice.
- **Egg gives structure.** One egg is enough to set 1 1/2 cups of milk with oats, because egg proteins link up and trap liquid as they heat. Too little egg and the bake stays loose, and too much makes it rubbery.

## Tips

- Use old-fashioned rolled oats; instant oats turn mushy.
- Let it rest 10 minutes before cutting so the slices hold.
- Add the nuts on top for crunch.

## Mistakes to avoid

- Using quick oats makes a pasty bake, so use rolled oats.
- Skipping the rest makes slices fall apart, so cool for 10 minutes.
- Overbaking dries it out, so pull it when the center is set and the edges are golden.

## Variations and swaps

- Apple cinnamon: swap the berries for diced apple and add a pinch of nutmeg.
- Peanut butter banana: swirl in 1/4 cup peanut butter.
- Chocolate chip: fold in 1/3 cup chocolate chips.
- Swap brown sugar for maple syrup and reduce the milk to 1 1/4 cups.
- Swap dairy milk for almond milk to make it dairy-free (use oil for the butter).
- Swap blueberries for raspberries or chopped strawberries.

## Storage

Refrigerate in a sealed container for up to 5 days or freeze portions for 2 months. Reheat in the microwave for 45 to 60 seconds, until steaming hot.

## FAQ

**Can I make baked oatmeal ahead of time?**

Yes. Bake it, cool it and refrigerate for up to 5 days, then reheat portions in the microwave. You can also assemble it the night before and bake in the morning.

**Can I freeze baked oatmeal?**

Yes. Cut into squares, freeze on a tray, then store in a bag for up to 2 months. Reheat from frozen in the microwave for 1 to 2 minutes.

**Can I use steel-cut oats?**

Steel-cut oats need much longer to soften and give a chewier texture, so this recipe is built for rolled oats. Use rolled oats for the best result.

**How do I know baked oatmeal is done?**

It is done when the top is golden, the edges pull away from the pan and the center feels set when you press it lightly.

**Is baked oatmeal healthy?**

It is high in fiber and fairly low in sugar when sweetened with fruit. Serve with yogurt for extra protein.
