Preheat the oven on 160 degrees Celsius or 320 degrees Fahrenheit.
Place a baking paper on the baking tray.
Mixing
Mix all the ingredients until you have a smooth dough ball.
Divide the dough in smaller pieces, and form the mini cookies. The cookies will run slightly so make sure there is enough space between the cookies on the baking sheet.
Baking
Bake the cookies for about 15 minutes, or until brown and cooked in the preheated oven.
In the meanwhile, you can chop the nuts in small pieces and melt the chocolate. You can melt the chocolate in the microwave or above a small saucepan with cooking water.
Picked the microwave? Add the chocolate in small cubes to a bowl. Place the bowl in the microwave and turn it on for 20 seconds. Give it a stir, and place in microwave for 20 seconds again. Just repeat until all chocolate is melted.
For melting the chocolate au bain-marie, you need to place the chocolate in a heat resistant bowl. Bring some water to a boil in the saucepan, and place the bowl on top of the pan. Keep stirring until the chocolate is melted.
Take the cookies out of the oven, take them off the baking sheet and let them cool down.
Decorating
Dip the cookies in the chocolate, and then sprinkle some chopped nuts on top. Continue until all cookies are done. 'Fijne Sinterklaas!'
