Both the black and white cookies are made the same way. Here are the directions for the the black cookies: Put softened butter in a large bowl and cream with a whisk.
When the butter is creamed, add powdered sugar in 3 batches, mixing after each addition until the individual grains can't be seen before adding the next batch.
Beat the egg and add it to the butter-sugar mixture in 3 batches, mixing and incorporating completely between additions.
Sift the dry ingredients. For the white cookies it's just the cake flour.
Mix the flours in using a cut-and-fold motion. Don't knead the dough.
When the dough comes together, take it out of the bowl and wrap it in plastic wrap. Flatten and chill in the refrigerator.
Squeeze the dough lightly to even it out. Roll out to a 4mm thickness. Preheat the oven to 340°F/170°C.
If the dough is hard to roll out, sandwich between 2 sheets of parchment paper before rolling. When it's 4mm thick, chill in the refrigerator for 5 minutes, then cut out into shapes.
Put the cookies on a parchment paper-lined baking sheet.
Bake for 16-17 minutes in a preheated 340°F/170°C oven for 6-7cm cookies. Cook for 10-12 minutes if the cookies are smaller.
Chill leftover dough and roll out again. If you mix the last bits of leftover dough, you can make marbled cookies.
While the cookies cool, make the icing to decorate. You can also use decorative squeeze tubes.
Put the egg white in the middle of a bowl of powdered sugar, and mix in the sugar gradually.
Adjust the consistency. It should just flow out flat when you dribble it from a spatula.
Put some of the icing in an icing bag with a small tip. Outline the shape first, and when the outline has hardened fill it with icing that's been slightly thinned out.
You can draw pictures or letters too.
You can buy food coloring specifically for icing, or normal powdered food coloring. For the black icing, I just mixed in black cocoa powder.
You can add colorful elements to both the black and white cookies. You can also just write directly on the cookies.
You can also draw pictures on plain round or square cookies without using special cookie cutters.
If you have very small children they may get scared if the decorations are too creepy, so make them cute. Please use your imagination to make whatever designs you can come up with.
Story Behind this Recipe
I drew fun Halloween characters using icing! By using specially shaped cookie cutters you can make even more designs. I hope you'll make a lot of these cookies!
Watch the consistency of the icing. For drawing outlines and letters it should be on the stiff side, and to spread out over a large area it should be on the loose side. When thinning out the icing, try adding a drop of lemon juice.
