Instructions
 

Bake the oatmeal
  1. Preheat the oven to 350°F (175°C). Brush an 8-inch square baking dish with the 1 teaspoon butter.
  2. In a large bowl, whisk the milk, eggs, maple syrup, melted butter and vanilla until evenly combined.
  3. Stir in the rolled oats, cinnamon, baking powder and salt. Fold in the diced apples, then transfer the mixture to the prepared dish and spread evenly.
  4. Bake for 35–45 minutes, checking at 35 minutes, until the edges are golden and the center is set without loose liquid. Ovens and baking dishes vary; use the set center rather than the clock alone.
  5. Let rest for 10 minutes, then divide into 6 portions. Serve warm, with optional milk or plain yogurt at the table.
