Whisk egg and yoghurt together.
Add flour and mix until it forms a smooth batter.
Add blueberries, mix through.
Heat a little butter or olive oil in a frying pan on low heat.
Drop spoonfuls of the mixture into the pan to form small pancakes.
Cook until the top has just started to set and the bottom is golden brown.
Flip over, and cook until the other side is golden brown.
Let cool for a few minutes - the berries will be quite hot.
