I never use microwaves - dont trust the nutritional quality of any food thats been zapped with radiowaves of whatever frequency
I use 200g ground almonds, 6 eggs, 2 tsp baking powder, 2 tsp vanilla essence, 100g erythritol, 2 tbsp thick cream or yogurt to make a batter ( using stick blender)
Add whatever you fancy in the cake
( my favourites are
100g blueberiies
125g raspberries
3-4 tbsp organic cocoa powder
1-2 small shots of stong expresso coffee with 75g pecan nuts but the only limit is your imagination / tastebuds)
pour into silcone cake / muffin moulds,, bake at 125 degrees for 40 -50 mins ( time needed varies for different fillings depending how much liquid they add. Muffins need less time - around half an hour as i remember ( only make thevcakes nowadays 8- 10 slices 2g carbs a pop)
