In a large bowl, cream together the butter, sugar and brown sugar.

Once mixed, then mix in the egg and vanilla.

Add the baking soda, cocoa, and flour and mix.

If the mix seems dry, add the milk a little at a time.

Add the semi sweet and milk chocolate chips and mix thoroughly.

Line two cookie sheets with parchment paper.

Drop teaspoon size dollops of cookie dough on the cookie sheet.

Cook for 10-12 minutes.

Remove from the oven and allow to cool and enjoy your triple chocolate chip cookies!
