Step 5: In the last minute, microwave the peanut butter for 20-30 seconds until pourable. Remove the chocolate banana oatmeal from the oven, drizzle it with the peanut butter, and leave it to cool for 5-10 minutes before serving. Enjoy!

Alternatively, swirl the nut butter into the top before baking for a firmer consistency, or include spooned dollops nestled in the oats for a ‘lava’ filling.

For a blended version: Blend the oats into a floury consistency, then add the remaining ingredients and blend until smooth. Pour into the dish and bake as usual.

FAQs

Can I make them into individual portions?

Sure! Divide the chocolate peanut butter banana baked oatmeal mixture into ramekins or a lined muffin tin and reduce baking time to 20-25 minutes.

Do I have to use cocoa powder?

You could omit it, slightly reduce the plant-based milk, and add vegan chocolate chips for delicious chocolate chip peanut butter banana baked oatmeal.

Why are my baked oats rubbery?

This is most likely due to overcooking, though not adding enough moisture/fat can also have a negative effect.

Pro Recipe Tips

  • To adjust consistency: More plant-based milk = softer, looser oats. A little less plant-based milk = firm, sliceable. Don’t add too little, or it becomes rubbery.
  • For cake-like baked oats: Blending the oats into oat flour makes a fluffier, cake-like bake.
  • For individual serve: Divide the mixture between greased ramekins or a muffin tin and bake for 15-25 minutes (based on size).
  • Cool slightly: Just a few minutes helps it set/firm, becoming easier to slice and serve.
