This Brownie baked oatmeal is a delicious make ahead breakfast for all the chocolate lovers! It is also great for meal prep for the busy week. The baked oats will last for days in the fridge, and can also be frozen to last longer. I like to serve with some yoghurt and berries, but they also tastes great just as is.

Baking oatmeal gives them a wonderful, almost cake like texture. Like having a healthy dessert, for breakfast! Another recipe to try is this Chocolate Baked Oats where the oats are blended to create a smoother texture.

More tasty baked oats recipes to try are these Blueberry banana baked oatmeal or this Carrot cake baked oatmeal.

Ingredients

This chocolate peanut butter baked oatmeal recipe is 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.
  • Rolled oats, or old fashion oats. They hold their shape while baked and create a great texture.
  • Flaxseed and Chia seeds, adding a combination of these seeds will add extra nutrients and it will also help with the texture when baked. These seeds are high in fibre, antioxidants and protein.
  • Baking powder, just a little to give these healthy chocolate baked oats a more of a cake like texture.
  • Cocoa powder, unsweetened and good quality or a deep chocolate flavor to these brownie baked oats.
  • Salt, a little salt really helps bring out all the flavours in this breakfast dish. 
  • Almond milk, or other plant based milk of choice.
  • Bananas, use very ripe bananas for the best texture and added sweetness. 
  • 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. 
  • Chocolate chips, I used dark chocolate chips, but any chocolate of choice will taste great. A chopped chocolate bar works great too.

Toppings

  • Yoghurt, of choice. 
  • Maple syrup, to taste
  • Fresh fruit or berries

See recipe card for quantities.

Substitutions and Variations

  • Nuts – add some chopped nuts of choice for some crunch and extra protein.
  • Protein – for added protein, mix in 2 tablespoons of your favourite chocolate protein powder into the oatmeal. 
  • Gluten-free – Although oats are naturally gluten-free, they can contain traces of gluten. To ensure a gluten-free baked oatmeal, use certified gluten-free oats.
  • Banana – Another option to the mashed banana is to use 1 cup of apple sauce.
  • Oats – Instead of using all rolled oats, use half quick oats and half rolled oats for a finer texture. For a blended and more cake like breakfast, try this Chocolate Baked Oats recipe.
  • Nut butter – These brownie baked oats has some creamy peanut butter added for a great taste and some added protein. Other nut butter of choice can substituted, or use sun butter for an allergy friendly breakfast.
  • Sweetener – This baked oatmeal is not overly sweet, mostly from the ripe bananas. There is a little maple syrup added, if you like it sweeter, add some more to taste. Other options to maple syrup are agave or other liquid sweetener or brown sugar.
  • Vegan – for a vegan chocolate baked oatmeal recipe, use almond milk or another plant based milk. Also use vegan chocolate chips.
  • Chocolate – To make this a double chocolate baked oatmeal, I have added some dark chocolate chips. Milk chocolate or while chocolate or any chocolate of choice will taste great. A chopped chocolate bar works great too.
  • Berries – Stir in 1 cup of your favorite berries, fresh or frozen.

More tasty baked oats recipes to try are these Apple pie baked oats or this Strawberry vegan baked oatmeal.

Storage

Store any leftovers without any toppings in an airtight container or ziplock bag. Place in the fridge for up to 4 days. 

You can also freeze these brownie baked oats. The best way is to separate the baked oat slices with a pice of parchment paper before placing them in a freezer friendly ziplock bag, or airtight container. This way they won’t stick together and you can easy take out a single serving at the time.

Eat leftover baked oats cold, or reheat this in the microwave. Serve with some vanilla yoghurt and toppings of choice.

Top Tip

These baked oatmeal have some added banana for sweetness and they also help hold it together when baked. For best taste and texture, use very ripe bananas in this recipe. They are sweet and get a creamy consistency when mashed.

If you don’t want to add bananas, substitute with unsweetened apple sauce.

FAQ

Can I double this baked oatmeal recipe?

Yes! To double this recipe for extra servings to freeze for later is a great idea. Simply double all the ingredients and baked the oatmeal in a 9×13-inch pan.

Can I freeze baked oatmeal?

Yes! Baked oatmeal makes a great meal prep and can be frozen for up to 3 months. Separate the baked oat slices with a pice of parchment paper before placing them in a freezer friendly ziplock bag, or airtight container. This way they won’t stick together when frozen and you can easy take out a single serving at the time.

How can I increase the protein?

The easiest way to add more protein is to add some of your favorite chocolate protein powder. Other good options are to serve the brownie baked oatmeal with a drizzle of peanut butter or top it with protein yoghurt.
