Hope that it will taste really good!
I'll bake it today and taste it to my coffee....;)
110 g butter, melted
250 ml (1 cup) brown sugar
1 tsp vanilla sugar
pinch of salt
250 ml (1 cup) flour
and any or all add-ins, like
Heat the oven to 175°C, and butter a small oven pan, about 20*20 cm.
Mix the brown sugar with the melted butter.
Add the egg and vanilla.
Stir in salt and flour, and any add-ins you'd like.
Pour this into the pan
bake for 20-25 minutes - it should be a little gooey when you pull it out.
Freezes very well, re-heats perfectly in the microwave,
and you can serve with some whipped cream and possibly a few berries.
If you wish, you can also made those in muffin form...
