@Granny_grump_ oops sorry K, meant to post this last night
Mug cake recipe base
1.5tbsp coconut flour
1.5 tbsp mix of other dry ingredients (I use 1 tbsp ground flax, 0.5 tbsp ground almonds)
0.5 tsp of baking powder
pinch of salt
1 large egg
1.5 tbsp full fat yoghurt (or milk/almond milk or similar)
0.5 tsp vanilla extract.
sweetener of choice to taste (I use the equivalent of about 3-4 tsp of sugar for this quantity but I don't like things too sweet)
stir dry ingredients in a bowl to make sure no lumps.
Beat wet ingredients together and then beat in sweetener.
Stir in dry ingredients, mix thoroughly – add more liquid if needed.
Mix will look quit sloppy to start with (think thick pancake batter) but will thicken quite quickly because of the coconut flour (think porridge).
put into moulds and put in microwave on full power for between 1min 30 secs and 1 min 45 secs. They are done when they start to come away from the side and look very slightly damp in the middle. Takes much longer to type than to do – I can have them on the rack cooling in about 5-6 mins.
This quantity makes 3 small cakes for me (about 2.5in square), I have used silicon cupcake moulds but now use a silicon mould which makes square cakes. If using silicon moulds remove to a rack quite quickly or they will get a bit damp on the outside. Handle carefully until cooled. Keep in a box in the fridge.
Very customisable -
Chocolate – replace some of the ground almonds with good cocoa power
Mocha – use cocoa as above but add a bit of strong coffee to replace part of the milk
lemon or orange – add grated zest plus a bit of flavouring.
Caramel - I use a flavouring for this, add it in addition to the vanilla.
(I got my flavourings from Home Bargains – not low carb but then you’re not using very much to each cake.)
Savoury – leave out the vanilla and sweetener, add in a touch more salt plus some herbs or some grated cheese.
You could add some melted butter or coconut oil if you want a richer cake
Can be zapped in the microwave for a few seconds and served hot with some full fat greek yoghurt as a pudding. Or split and buttered (my own preferred

) or with some cream cheese (flavoured and used as a topping), with melted chocolate in the mix or drizzled over the top if you’re feeling fancy – you get the idea.
Most recent version I made (chocolate made with yoghurt and cocoa powder) were about 2.6-2.7 g of carb each I think according to my spreadsheet.
Evidence for the prosecution - last remaining one of the batch
