Add all ingredients except the butter to a blender. Blend for 30 seconds or until smooth.

Heat a small amount of butter in a frying pan over medium heat.

Pour in about ¼ cup of batter, then swirl the pan to evenly spread it into a thin circle.

Cook until the edges are dry and the center is set, then flip and cook the other side for 20–30 seconds.

Remove from pan and repeat with remaining batter.
