Making coffee pudding?!

Making coffee pudding?

I got this chocolate pudding recipe but i want to make coffee pudding using exactly the same ingredients in this recipe.

185g Self raising flour
1 level tsp Baking powder
2tbsp Cocoa powder
150g caster sugar
2 eggs
2 tbsp golden syrup
200ml milk
200ml vegetable oil

I just wanted to change cocoa powder into nescafe blend but I'm not quite sure whether that would work.

Should I put 150 ml of coffee and change the amount of milk ?
Should I just put 2tbsp of nescafe blend and put the same amount of milk as above?

I would just add about 2 teaspoons of coffee extract.

I think that if you used regular coffee, in order to get the taste you want, you'd need to add too much and too much liquid = your pudding not setting up.
