Mix together the butter and sugar using a spoon or stand mixer on low speed
Add the beaten egg and vanilla, mixing until well combined. It may look separated, but will come together once you add the flour so don’t panic
Add your flour, a little a time until you get a thick dough. You may need to finish off the mixing using your hands and kneading the last bits of flour in.
Bring the dough together in a ball and wrap in cling film, place in the fridge for approx 30 minutes to chill and firm.
When you are ready to roll out your dough, put the oven on approx 160 degrees and line a few baking trays with greaseproof paper.
Roll out your dough on a lightly floured surface, to about 1/2cm thickness.
Use your cookie cutters or plunger cutters to cut out your shapes, then transfer them to a baking tray. Bake the cookies for approx 8-10 minutes, but essentially until they just start to go golden.
Leave the cookies to cool on a wire rack.
Now you can decorate or simply leave plain and enjoy!
