Add vinegar to the milk and let it sit for 5 mins till it curdles.
Then add condensed milk and mix it well till fully combined.
To this, add flour, cocoa powder, baking soda, milk powder and give it all a good whisk to achieve a smooth batter. It should have a ribbon like consistency.
Now, heat a griddle or non-stick pan on low-medium heat. Pour the pancake batter over the hot griddle using a ¼ cup or a scoop to measure out equal portions every time.
Cover the pancake with a lid and let it cook for 3-4 mins on low heat. Flip it and cook the other side for another minute or two.
For the filling, just heat the cream and chocolate chunks in a microwave at 30 seconds intervals till everything is melted and combined. Surface wrap the ganache and let it thicken in the fridge for 2-3 hours.
Spread some of the chilled chocolate ganache on the pancake and sandwich it with another. Seal the edges to achieve the perfect look.
