Slit pavs from one of the sides, till far inside as you can.
Do not allow any of the other sides to get pierced.
Let the slit be as long as the side. Keep aside.
Mix all ingredients together except butter and condensed milk.
Open slit a bit and coat insides with condensed milk.
Still holding it open, sprinkle in a tbsp. of the mixture.
Press well together so that mixture is sealed in nicely.
Repeat for all other pavs. Melt butter lightly.
Brush all pavs with the butter.
Bake in a hot oven for 5 mins or till crust is crisp.
Serve hot with hot or chilled coffee.
They taste good as a cold treat too
