Chewy Chocolate White Chocolate Chunk cookies

I came across this recipe at Annie's Eats and really liked it. The cookies are delicious, chewy as promised and white chocolate complement the dark chocolate cookie well. I substituted the all-purpose with whole wheat flour and used brown sugar to make it healthier.

Ingredients
1 cup whole wheat flour
1/4 cup all purpose flour
1 tsp baking powder
1/2 tsp salt
2/3 cup dutch-process cocoa powder (I used natural since I did'nt have dutch process)
1/2 cup unsalted butter
1 cup dark brown sugar (gur-sakhar)
few drops of vanilla extract
1/3 cup milk
1 1/2 cup coarsely chopped white chocolate

Method

Sift the dry ingredients together and leave aside. Cream the butter and sugar until light. Add the vanilla extract. Fold in the flour and milk alternately in two batches. Add the white chocolate and fold gently. Make small balls and place the cookies on a baking tray lined with baking paper. Flatten them slightly. Remember to keep some space in between to allow the cookies to expand. Bake at 180 C for 10-15 minutes or until the tops do not look wet and spring back on touch.

Allow to cool on a wire rack and enjoy with a cup of cold milk.
