Hi Lailarose have trawled through my books & cobbled together this recipe which I have just trialled. It is NOT Dukan & I'm not suggesting it's a good idea to scoff on a diet but if you have a celebration it's much lower carb, fat & sugar & don't forget it's only 1 slice! I think I can prob improve on this but it's a pretty good 1st attempt-moist & chocolatey.
Beat tog. 25g sweetener, 3 egg yolks & 50g butter. Beat in 150g 0% yog, 1/4 tsp vanilla essence & 3 tbs strong coffee. Fold in 45g fat reduced cocoa, 3/4tsp baking powder, 3/4 tsp bicarb. soda, & 50g flour. (Will be quite thick & pasty now) Fold in 150g finely grated courgette, dried in paper towel then beaten egg whites. (need to be beaten to stand in peaks) Bake approx 30 mins in 2 sandwich tins @ 170. Should be springy to touch & just coming away from edge of tin. Turn out & cool.
In a pan heat 2tbs sweetener, 2 tbs cocoa, 1/2 tbs syrup, 250ml water. Add 2 tbs cornflour slaked in a little water & whisk to smooth. Cook to thick glue consistency, cool. Use custard to sandwich & cover cake. (may not need all)
I think butternut squash puree could be a good substitute for the courgette as naturally sweet & look better, may be able to then reduce sweetener more?1?
DD I'm sure your sprinkles & malteser version will of course be far superior!
Enjoy your parties!
