Place the coconut oil, maple syrup, vanilla, and salt, in a stand mixer (or a bowl with a hand whisk) and mix until lighter in colour and well blended (about 2-3 minutes)
With a wooden spoon, mix in the flour, lemon zest and lavender flowers so it comes together as a dough. Pop the dough in the fridge for 10-15 minutes as this helps to roll it out.
Remove the dough from the fridge and place the dough in between 2 sheets of greaseproof paper and roll out gently until approximately 1/2cm/2/8" thick.
Cut out using your preferred shape - note that this is a relatively soft dough so the simpler the better. For example I usually use a plain round cutter approximately 7cm/3" wide.
Place the cut-out shortbreads on baking trays lined with parchment paper.
Bake in the pre-heated oven for approximately 10-12 minutes until turning slightly golden (but don’t allow to colour too much).
Leave to rest for 5 mins on the trays before transferring to a wire rack to totally cool.
These biscuits will keep in a closed tin for approximately 5 days.
