Preheat oven to 325 degrees.

Line your cookie sheet with parchment.

In a large mixing bowl combine your flour, sugar, cocoa, baking soda, baking powder, salt, pistachios and chocolate. Set aside.

In a small mixing bowl combine water and vanilla. Mix. Add eggs. Mix again.

Pour your wet ingredients into your dry ingredients and mix well. It should form dough that is slightly crumbly.

Now take the dough and turn it onto a lightly floured surface. Knead it about 8 to 10 times. The dough should be soft and slightly sticky at this point.

Now roll it out until you have a 1 inch thick slab.

Transfer carefully to the baking sheet.

Bake in preheated oven for about 30 minutes, or until slab is firm and dry.

Remove and cool on a wire rack for about 10 minutes.

Cut with a serrated knife into ½ inch thick slices (I did mine thicker for mini-me) and place the pieces back on the cookie sheet. Return to oven for about 10 minutes.

Turn them all over and cook for another 10 minutes.

Remove and let cool.

Serve with a big old chocolatey, crumb-y smile!
