Mix the flour with baking powder, sugar, salt, and vanilla sugar first, and then add the wet ingredients: the egg, soft butter, lemon extract, and vodka.
2 cups All Purpose Flour, 1 Teaspoon Baking Powder, ¼ cup Powdered Sugar, pinch Salt, 2 Teaspoon Vanilla Sugar, 1 Egg, ½ cup Butter, 5 drops Lemon Extract, 1 Tablespoon Vodka
Mix the whole content and then work it for a few minutes to a smooth dough.
Form it into a big sausage, wrap it in plastic, and let the dough cool for 1 hour in the fridge.
Just before you roll out your dough, preheat your oven to 180 degrees Celsius.
Take it out from the fridge and roll your dough 4 millimeters thick. Cut out with a cookie cutter while using extra flour at the side so that the dough shapes don't stick.
Place on a baking tray and bake for about 10 minutes.
While the cookies cool, prepare the icing by mixing the powdered sugar with the food coloring and vodka.
Place the icing into a piping bag and decorate your cookies with the icing, and then push the colored sugar balls into the icing.
...and Sugar deco such as blue sugar balls
Let the icing get hard and store it in an airtight container if you live in the tropics, and in a cold climate, store it in a metal box (+apple skin to keep the cookies soft).
