Apple-Walnut Cinnamon Baked Oatmeal

1. Preheat the oven to 190°C. Lightly grease a 20 cm square baking dish with some of the 15 ml oil. Wash, core and dice the apple into 1 cm pieces.

2. In a large bowl, mix 180 g oats, 5 g baking powder, 2 g cinnamon, 1 g salt and 25 g brown sugar until evenly combined.

3. Beat 1 egg in another bowl; whisk in 250 ml milk, 100 g unsweetened applesauce, the remaining oil and 5 ml vanilla. Pour into the dry ingredients, add 180 g apple and 30 g walnuts, and stir until no dry patches remain.

4. Spread the batter in the dish and bake on the center rack for about 30–35 minutes. Check for lightly golden edges and a set center, then use a food thermometer to confirm the thickest central part reaches at least 74°C (165°F). If below 74°C or wet batter remains, bake in further 3–5-minute intervals and measure again. Appearance or a skewer alone cannot establish safe doneness.

5. Rest for 5 minutes, cut into four portions and serve warm. Cutting immediately may make it crumble.
