Whisk eggs, milk, cocoa powder and sweetener/sugar until combined well and free from lumps. Add bread (one at a time) and thoroughly soak through. Spray a good quality nonstick pan or skillet with cooking oil spray, and fry bread on low - medium heat until cooked on both sides (about 4-5 minutes each side). Repeat with remaining slices.
While toasts are frying, prepare Chocolate Cherry Cheesecake and Chocolate Maple Syrup...
Chocolate Cherry Cheesecake:
In a medium-sized bowl, add the cream cheese, yoghurt, cocoa powder and sweetener/sugar, and mix until smooth. Fold the cherries through and mix again.
Chocolate Maple Syrup:
Combine maple syrup and cocoa powder in a jug, and whisk really well until combined.
Now Stack!
Stack french toasts with cheesecake filling and top with syrup.
Notes
I used thick, chunky sourdough bread for these toasts, which allowed for 6 slices for the quantity of chocolate egg wash (and 3 serves) BUT if using thinner normal sandwich bread slices, the egg wash could easily allow for 8 slices and serve 4.
