A day without chocolate is a lost day! Therefore: Chewy Marshmallow Chocolate Cookies

Well, well, well, well, well, what shall I say? Hopefully more then just 'well, well, well'!
Hm, maybe get it over with? I don't know. I suppose nothing much would be gained with the year being over already. In fact every day is worth to be turned into a good and enjoyable one. There is the saying: "A day without chocolate is a lost day!"
No? There is no such saying? Well, let's have one then and prepare some chocolate cookies ...

Well (to bring it up again), we are using some marshmallows and a few other things as well, namely ...

Ingredients:
100 g butter
100 g sugar
1 tbs peanut butter
A splash of rum (if you like to)
200 g flour
1 tsp baking powder
80 g chocolate
150 g mini marshmallows
80 ml cream

Preparation:
Thanks to Karen, if I may say so, I have now a new way of preparing dough for baking. In fact, now there is one more use for my 'beloved' pan. As far as I am concerned, manufacturers are having a crisis, because I'm not buying, since I have a universal pan I nearly do everything with and no it's chewy marshmallow chocolate cookies.
Therefore I started by melting the butter in the pan. As soon as that has happened I turned off the heat and took the pan from the heat.
Next I put in the sugar, the peanut butter and the splash of rum and starting mixing those things through.
After that the flour and the baking powder followed to be incorporated.
In the next step the chocolate, the marshmallows and the cream were added to get a luvly cookie dough.
Said and done, it's time to place bits of the dough on baking sheets and transfer to the oven for 15 minutes at 180°C.
Reserve a bit of time for cooling after baking and then ... 

... well, well, well, have a bit of chocolate by eating those chewy marshmallow chocolate cookies.
If that won't do it, have a look at the December Improv Challenge.
