Put all ingredients ( except raisins) in a blender and pulse until you get a thick, textured batter. Add more oat milk if you think it's too thick ( it should be thicker than normal pancake batter).
Mix in the raisins. If you have time, rest the batter for about 15 minutes.
Mix in the batter a few drops of oil.
Lightly oil a pancake pan or a heavy-based frying pan, then add 4-5 drops to the pa and create round shapes. They don’t have to look perfect. Fry for about 2 minutes on each side until golden, then transfer them to a plate. Repeat with the remaining batter.
Serve warm or at room temperature.
