Heat the oven to 180C and line a baking sheet with parchment paper.

Place the butter and sugar in a mixing bowl and beat until the mixture looks pale and fluffy.

Add the vanilla extract and stir it through the creamed mixture.

Tip in the flour and mix until a soft dough forms and no dry streaks remain.

Divide the dough into four portions and shape each one into a bone by rolling a short log then pressing small balls of dough onto both ends.

Set the shaped pieces on the prepared baking sheet with space between them.

Bake for 12 to 15 minutes until the edges turn a light golden color.

Remove the sheet from the oven and let the biscuits cool fully on the paper before moving them.
