Line a baking tray with parchment paper.
Place the butter, caster sugar and lemon zest in a large bowl. Using a wooden spoon cream the butter and sugar together until the ingredients are light and fluffy.
Gradually add the sifted plain flour and continue to mix until the ingredients turn into a ball.
Turn out onto a lightly-floured board and roll out the dough to a medium thickness (about 1cm).
Cut the dough into biscuit shapes with your choice of cutter. This is where you can have real fun with different shaped cutters!
Place biscuits on parchment-lined baking tray and bake in a medium pre-heated oven at 180 degrees for 10-12 minutes (keep an eye on the timings as the biscuits can overcook very easily).
Then relax and enjoy the delicious flavours of lavender biscuits with a refreshing cup of tea.
