In a large bowl, mix the butter and sugar until soft and creamy.
Add the egg and mix well.
Stir in the vanilla extract.
Add the flour, baking powder, and salt, and mix until a dough forms.
The dough should be slightly flaky and break easily — this is exactly what you want.
Roll out the dough with a rolling pin to about 1.5 cm thick (around 0.6 inches).
This thickness is the secret to rich, buttery cookies that don’t dry out.
Cut with your favorite cookie cutters and place on a baking tray lined with parchment paper.
Bake at 180°C (350°F) for about 10 minutes, just until the edges are barely golden.
Remove from the oven, let cool completely, and decorate if you wish.
Notes
Simple White Glaze (for decorating)
Mix icing sugar with a few drops of water or lemon juice until you reach a thick but pourable consistency. Use a spoon or piping bag to decorate the cookies, then add sprinkles or edible decorations before it sets.
Ginger Spice
Want a ginger touch? Simply add 1 teaspoon of ginger spice powder to the dry ingredients. The result is warmer, more aromatic cookies with a subtle Christmas spice that pairs beautifully with white glaze or chocolate decorations.
