These pancakes taste best when they are freshly made but keep well in the fridge for 2-3 days. You can also store them in the freezer for up to 3 months.
If you want to store them stacked on top of each other you probably want to place a piece of parchment paper between each pancake, or they’ll stick together.
The best way to reheat the pancakes is to melt a small knob of butter in a pan on medium heat and place the pancakes in there. It only takes about 30 seconds on each side to heat them up.
