Substitutions

- Sweetener – instead of maple syrup, other liquid sweetener like agave syrup or brown sugar can also be used. If you like a sweeter dish, add more sweetener to taste, or top the baked oatmeal with a drizzle of maple syrup.

Variations
- Protein – For added protein, mix in 2 tablespoons of your favourite protein powder into the oatmeal. Some great flavours to use are vanilla or berry flavor.
- Gluten-free – Although oats are naturally gluten-free, they can contain traces of gluten. To ensure gluten-free baked oats, use only certified gluten-free oats. They can usually be found in the glute-free section of the grocery store.
- Sweetener – This baked oatmeal is not overly sweet. Most of the sweetness comes from the very ripe bananas and just a little added maple syrup. If you like a sweeter breakfast, taste the oatmeal before baking and add more sweetener to taste, or top the baked oatmeal with a drizzle of maple syrup.
- Vegan – for a vegan baked oatmeal recipe, use a plant based milk, like almond milk, soy milk or oat milk. If topping with yoghurt, ensure it is plant based.
- Nuts – add some chopped nuts to this baked oatmeal recipe. Some good options are walnuts, almonds or pecans, but any nut of your choice works! For allergies, leave the nuts out or use sunflower or pumpkin seeds.

Storage
This healthy blackberry baked oatmeal makes 9 portions and is a great meal prep for the week! To store baked oats, first let them cool down to room temperature. Cut into pieces and place in an airtight container or ziplock bag. Store in the fridge without any toppings, it will keep for up to around 4 days.
You can also freeze baked oatmeal for up to 3 months. I like to divide the pieces with some parchment paper. This way, it is easy to take out a single serving and the pieces won’t stick together. Place the baked oatmeal in a freezer friendly ziplock bag or an airtight container. Let defrost in room temperature and serve cold, or reheat in the microwave. Serve with some vanilla yoghurt and toppings of choice.

Top Tip
For a sweeter baked oatmeal, add some brown sugar to the oatmeal mixture before baking. All depends on how sweet you like it and the ripeness of the bananas. Top with a drizzle of maple syrup to taste.
The crumble topping is optional but I highly recommend it! Makes this dish taste like a healthy blackberry crumble. Top with some vanilla yoghurt and fresh blackberries. Soooo good!
