In a bowl, beat room temperature butter until smooth and creamy.

Add the sugar and mix on medium speed for 2-3 minutes until fluffy.

Add the egg, salt, and vanilla extract, and whisk to combine.

Gradually add the flour while mixing on the lowest speed. If using a stand mixer, switch to the dough hook attachment. If using a hand mixer, switch to a wooden spoon or knead by hand.

Once the dough comes together, wrap it in plastic wrap and refrigerate for 30 minutes.

Dust your surface with flour, roll out the dough to your desired thickness, and cut into shapes using cookie cutters.

Place the cookies on a baking tray lined with baking paper.

Preheat your oven to 160°C (329°F) and bake the cookies for 8-12 minutes, or until the edges are lightly golden.

Transfer the cookies to a cooling rack and let them cool completely at room temperature.
