If those are the ones you so kindly gifted me, they are absolutely amazing!
I'm not sure if you're only interested in quick and bought things, but I was just reminded of one of my favourite treats today. Very easy to make:
100 gr dark chocolate (85% cocoa or more)
60 gram nut butter (I like almond butter but peanut butter works as well)
60 gram butter (original recipe says you can use coconut oil instead, interesting for your on and off vegan brother, never tried it)
Lots of nuts and seeds
Melt everything together and mix with nuts when melted. I like to add chilli powder and clove powder. Pour in container and let set in fridge until it can be cut into small cubes. Some nuts on top makes it look extra festive, or you can even add Christmassy gold.
I usually multiply this recipe and freeze in smaller batches.
