Baked oatmeal is a great option to regular oatmeal like this Carrot cake oatmeal or to overnight oats like this Blueberry overnight oats. Baking oatmeal gives it a wonderful, almost cake like texture and makes a healthy, breakfast meal prep. The baked oats will keep for several days in the fridge, or freeze it to last for even longer. Also try this Blueberry banana baked oatmeal or this Banana bread baked oats.

I like to make this recipe when blackberries are in season, but it can also be make with frozen blackberries all year round. Another great blackberry recipe to try are these Vegan blackberry muffins.

Ingredients

This healthy Blackberry Baked Oatmeal is fast and easy to make. All that is needed are a few basic ingredients. The perfect meal-prep for the whole week!

For the full ingredient measurements, scroll down to view the recipe card at the bottom of the page.

The ingredients in small bowls.
  • Bananas, use very ripe bananas with dark spots for the best texture and added sweetness. 
  • Almond milk, or other milk of choice. For a vegan oatmeal, use a plant based alternative. 
  • Maple syrup, or other liquid sweetener like agave or honey for non vegan. Brown sugar or coconut sugar can also be used.
  • Vanilla extract, a little vanilla ads a lot of flavor to this blackberry oatmeal bake. 
  • Rolled oats, or old fashion oats. They will taste the best when baked, they hold their shape and create a great texture.
  • Chia seeds, these seeds will add extra nutrients and it will also help with the texture of the baked oatmeal since this recipe is egg free. Chia seeds are also high in fibre, antioxidants and protein.
  • Baking powder, just a little to give this baked oatmeal more of a cake like texture.
  • Cinnamon, some warming cinnamon spice adds so much flavor. 
  • Salt, a little salt really helps bring out all the flavours.
  • Blackberries, use fresh or frozen. No need to defrost them if you go with frozen berries, just add them to the oatmeal before baking. 

Streusel Topping (optional)

  • Rolled oats, or old fashion oats.
  • All purpose flour, use gluten free if needed.
  • Coconut sugar or brown sugar. Add more for a sweeter topping.
  • Coconut oil, or neutral oil of choice 
  • Cinnamon, some warming cinnamon spice adds so much flavor. 

Toppings (optional)

  • Vanilla yoghurt, or other thick yoghurt of choice. 
  • Maple syrup, to taste
  • Blackberries

See recipe card for quantities.

Hint: These healthy blackberry oats have an optional, crunchy topping. But I highly recommend it. It will transform these oats to almost a healthy oatmeal crumble, like having a healthy dessert, for breakfast!

Substitutions

  • Berries – This recipe uses either fresh or frozen blackberries. They can also be replaced with other berries, or a mix of berries of choice. Some good options are raspberries or blueberries, also check out this Blueberry banana baked oatmeal. 
  • 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!

Can you freeze baked oats?

Yes, baked oatmeal can be frozen for up to 3 months. Place the baked oatmeal in a freezer friendly ziplock bag or an airtight container. I like to separate the pieces with some parchment paper. This way, they won’t stick together and you can easily take out a single serving.
