Decadent Chocolate Wafers

Pulse flour, cocoa, sugar, salt and baking soda in the food processor several times till their mixed well. Cut the butter into 10-12 cubes and add them to the flour mixture. Pulse several times till the mixture looks like coarse sand. Combine the milk and vanilla in a small cup. With the processor running, add the milk mixture and continue to pulse until the mixture clumps around the blade or the sides of the bowl. Transfer the dough to a large bowl and knead a few times to make sure it is evenly blended. Form the dough into a log about 2 inches in diameter. Wrap the log in cling film or foil and refrigerate for at least one hour or till firm enough to slice neatly.

Sieve flour, cocoa, sugar, salt and baking soda in a bowl. Mix well with a fork. Rub the cubes of butter into the flour mix with your fingers, as you would while making pie dough, till the mixture resembles coarse sand. Add the milk tablespoon by tablespoon till the mixture just come together. Like the recipe states, I needed about 5-6 tablespoons of milk, but you might require less. Do not overwork the dough. Gather into a log, wrap and chill as mentioned above.
