I made these wonderful little blondies a few days ago, and I won't even bother to tell you how good they were, because it'll won't take you more than half an hour to whip up your very own batch. Go! Go!
I found this at Smitten Kitchen - thank you, thank you, thank you.
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
I added about 50 ml (that's a little more than three tablespoons) each of dark and white chocolate, and 100 g of toasted hazelnuts.
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, and 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 for real decadence, serve with some whipped cream and possibly a few berries.
