CREAM 1 cup of sugar and 1 cup of butter using your stand mixer. WHILE whisking, add in one egg and 1 teaspoon of vanilla extract. MIX 2 teaspoons of baking powder and 3 3/4 cups flour together.
Add the mixed dry ingredients slowly to the buttercream mixture until incorporated. REMOVE from the stand mixer and form into a large ball. HEAT UP your oven to a temperature of 400 degrees Fahrenheit or 200 degrees Celsius.
LIGHTLY flour your workspace and your rolling-pin. ROLL out the cookie dough to desired thickness. The rule of thumb is that baking time increases with cookie thickness.
Cut out hearts and stars, or any other shape you like. Transfer the shapes onto a pre-lined baking tray.
BAKE the cookies for at least 7-10 minutes, depending on the thickness of your cookies. Check every now and then, the Christmas cookies should be light in colour with slight browning on the edges.
CONTINUE baking cooking until you've used up all of your cookie dough. REMOVE the tray from the oven and place the cookies on the cooling rack. Make small holes using a skewer when the cookies are still hot.
You can use these holes to add strings too, later on. Make sure you do this when the cookies are cooled down otherwise you might break the cookies.
HANG them in your Christmas tree and let your family members pick one (or more!) to enjoy on your Christmas evening.
