Chocolate Gingerbread Cookies

I did steal this recipe from Martha Stewart but have modified several ingredients.

Ingredients

1 cup roughly chopped dark chocolate
1 1/2 cups plain flour
1 tsp ground cinnamon
1/4 tsp ground cloves
1/4 tsp ground nutmeg
1 tbsp grated fresh ginger
1 tbsp cocoa powder
150g butter, at room temperature
1/2 cup brown sugar
1/2 cup treacle
1 tsp baking powder
1 1/2 tsp hot water

1. Combine flour, cinnamon, cloves, nutmeg and cocoa powder. Set aside.
2. Beat butter and ginger until pale. Add brown sugar, beat until combined. Add treacle, beat until combined.
3. Dissolve baking powder into the water (the mixture will fizz slightly).
4. Mix half the combined dry ingredients into the butter. Mix in baking powder and the remaining dry ingredients into the batter. Mix in chocolate. Refrigerate for 2 hours.
5. Pre-heat oven to 165 degrees. Spoon 1 tsp of the dough and use your hands to roll into a ball. Bake for 10 - 12mins. Once baked, use the back of the teaspoon and press gently into the center of the cookie to make an indentation. The cookie should be soft enough to do this and the edges might crack slightly.
