Step 1

Add oats, milk, chia seeds,(and sweetener if desired) together in a mason jar, resealable container or a bowl. (If you like your oatmeal more creamier, you can add more milk and less if you like them on the chunkier side - you can also add an extra 2 tablespoons yogurt (dairy free if needed) to make them creamier).

Step 2

Add mashed banana, cinnamon and sweetener, if using.

Step 3

Shake jar or mix and combine with a spoon. Seal and chill in fridge for at least 4 hours or overnight.

Step 4

Serve with more milk as desired and top with fresh banana slices and walnuts before serving, if desired.
