Place sugar into the Thermomix bowl and mill 10 sec/speed 10.
Add butter, cocoa, eggs, salt, vanilla and baking powder and blend 10 sec/speed 6.
Add flour and combine 10 sec/speed 6. Repeat as needed until you have a smooth texture. This is quite a stiff mixture.
If you are planning to serve these straight away, then really you can go ahead and cook them now. If you are planning on serving them later in the day or even the week, then portion batter and freeze until you are ready to bake.
When ready to serve, preheat oven to 180°C and line a muffin tin with silicone liners, or grease liberally and dust with cocoa.
Divide the batter between the prepared liners and bake for a maximum of 10 minutes. They need to be completely soft in the centre when you serve them.
Dust with icing sugar, serve immediately with or without garnishes. I do think ice cream is a no brainer with these. Happy Valentine's Day!
