Boil water and stir in the oats. I didn’t feel like using a pot so I took a shortcut and used an electric kettle. Cover the oats for 5 min till they “cook.” Add the rest of the ingredients except banana and goji berries, and stir well. Layer sliced banana and goji berries on top.
Substitute: cacao powder for carob powder; milk of your choice for water. As you can imagine substituting will alter the taste slightly but that’s the fun of playing around with different ingredients.
