Mix in the instant coffee powder and vinegar. Mix till the coffee dissolves.
Next, add the sugar and sunflower oil. Mix it well.
Now, add the whole wheat flour, cocoa powder, baking powder and baking soda. Whisk everything to form a smooth batter.
Clean the edges with a spatula and sprinkle the chopped almonds generously over the batter.
Place the pan over a tawa set on medium high heat and cover it with a lid. Cook it for 30-35 minutes on medium heat or until a skewer inserted in the centre comes out clean.
Alternatively you can also bake it in the oven at 180°C for 30-35 minutes.
Once done, sprinkle the milk chocolate callets over the hot cake and cover with a lid for 2 minutes so that the callets can melt slightly.
Cut into slices and have warm.
