Tiger Gingerbread

I am not sure if I found this on the web or in a book, but I have it listed as 'Tiger Gingerbread', and it is truly awesome, so here it is:

Tiger Gingerbread
1/2c cold water
2 tbsp ground coffee
1 piece fresh ginger, 1 inch long, peeled and coarsely chopped
1/2c unsalted butter
1c dark brown sugar (packed)
1/2c dark molasses
1 large egg
1.25c all purpose flour
1/2 tsp salt
3/4 tsp baking soda
1/2 tsp ground ginger
1/2 tsp cinnamon
1/2 tsp nutmeg

Preheat oven to 350° F.  Grease a 8" square pan.
Combine the water, coffee, and fresh ginger in a small pan.  Bring to boil, then remove and cover, letting it steep at least five minutes.
With mixer, beat together butter, brown sugar, molasses until smooth.  Filter the coffee mixture (or use mesh screen) and mix in.  Add egg.
Sift the flour, salt, baking soda and spices into the mixture, and beat until smooth. 
Pour batter into the square pan and bake until toothpick inserted comes out clean, around 30 minutes.  Cool in the pan five minutes before slicing.  Serve warm with ice cream (dulce de leche is incredible on this).
