Spoon almond flour into medium sized coffee mug (with baking powder if using, for more rise and faster cooking but I prefer taste without)

Add olive oil, egg, salt and pepper. Mix well with a fork.

If batter is very thick, you can thin with a little milk or cream.

Cook at full power in microwave oven for one minute. If not fully set on top, cook for a further 30 secs.

Remove from mug, slice and butter while still hot.
