Step 1

Add the flour, butter, sugar, salt, vanilla extract, and egg into a large bowl. Use your hands to knead the dough until the dough forms a ball (this takes around 5 minutes).

Step 2

Wrap the ball of dough in cling film and place it in the fridge for 30 minutes.

Step 3

After the 30 minutes are up, remove the dough from the fridge. Also preheat your oven to 350 degrees Fahrenheit and line your baking sheets with parchment paper.

Step 4

Sprinkle flour onto a smooth surface and roll out the dough with a rolling pin until it is approximately 3/8 inch thin. Use your cookie cutters to cut out the cookies and place them on the parchment paper. Once you've used up the rolled out dough, gather the leftovers, form another ball, roll it out again, and cut more cookies. Repeat the process until you have used up all the dough.

Step 5

Bake your cookies in the middle rack of your oven for around 10-12 minutes until the cookies are lightly golden brown along the edges. Depending on your oven and how thick your cookies are, your baking time might be slightly shorter or longer.

Step 6

Remove the cookies from the oven and let them cool on the baking sheet for around 5 minutes. Then remove the parchment paper with the cookies on it from the baking sheet and let the cookies cool fully.

Step 7

OPTIONAL: After the cookies have cooled sufficiently, you can prepare the topping by whisking powdered sugar and lemon juice or water together in a small bowl. This will be your "glue" for sprinkles and other decorations. Spread a small amount of the "glue" onto the cookie and then decorate as desired. You can get really creative here. If you decide to decorate your cookies with icing and/or sprinkles, let them sit until the glaze has hardened.
