Baking season opened with chestnut biscuits

As the subject line says: with the baking of chestnut biscuits my annual Christmas baking season has officially opened today. I'm not planning such a baking orgy as last year - "only" 20 different biscuits/cookies/whatever are on the baking plan, and I might leave out one or two. I know it's still a lot, but not 30+ at least, right?

In case anyone is interested, the biscuits turned out very tasty. Below is the recipe.

Ingredients for about 80 chestnut biscuits
*200 gr sweet chestnut puree
*150 gr white flour
*100 gr butter or margarine
*100 gr powdered sugar
*2 small eggs
*2 tablespoons of rum
*1 tablespoon of vanilla favoured sugar
*80 pieces of small, round baking wafers (Backoblaten in German, if someone is familiar with the term)
*chocolate icing to decorate them
*baking paper for the tin

And so are they made:
* Stir the soft butter with the chestnut puree, the icing sugar, the rum and the vanilla sugar until you you get a unified, smooth mass.
* Add eggs and flour. Stir until the surface is completely smooth.
* Fill the mass into a decorating sack (term??) with a star-shaped opening and press little amounts into the middle of the baking wafers.
* Bake on 190°C in a pre-heated oven for roughly 25 minutes, until they are light brown-
* Take them from the tin while still hot and decorate with chocolate icing.

My apologies for using the metric system. My brain doesn't work in cups and ounces and the likes.
