Preheat oven to 190C/375F/Gas 5
have 2 or 3 flat baking trays ready covered with baking paper.
Chop the softened butter and whip in a bowl with the sugar till light and fluffy.
Beat the egg in a cup and add half to the butter mix and stir, then add half of the flour and baking powder, stir and then add the rest of the egg and the remaining flour etc. Add the lavender flowers last.
Place teaspoonfuls of the batter on to your prepared baking sheets and space well apart as they spread a lot.
Bake for 10-15 minutes or until golden and just a teeny bit crisp round the edges.
Cool on wire rack and if you are like me you'll eat more than your fair share before any guests arrive.
