You also need a 500 ml jar with a lid, e.g., the CORK box with lid from Ikea.
Put the oatmeal and chia seeds in the glass, pour the yogurt over it and mix everything together. Cut the banana into thin slices and place on top, then core the cherries and layer them on top. Finally sprinkle the desiccated coconut on top.
Seal the jar and place in the refrigerator overnight.
