Preheat the oven to 340f/170c/150 (fan)

Mix all of the ingredients together in a bowl until you've got a nice smooth dough.

Flour your work surface and push the dough out with the palm of your hand to begin flattening it.

Use a floured rolling pin to gently roll it out fully until it's about 1/2 an inch thick. It's quite crumbly, so keep pushing it back together with your hands.

Use a cookie cutter to cut out the shapes, and lay the shapes onto a baking sheet (no need to grease it first).

Bake in a preheated oven for 15 minutes, take out of the oven and leave to cool on a cooling rack.

Store in an airtight in, in the fridge for up to one week. Or store for longer in the freezer.
