Preheat the oven to 350F / 175C and line an 8" / 20cm square baking pan with parchment paper.
In a medium-size bowl, stir together the vanilla, coffee, water and pumpkin puree.
Stir in the sugar, flour, cocoa powder, baking soda, baking powder and salt.
Tip the brownie batter into lined baking pan and bake in the center of the oven for 25 minutes, until the edges and the top of the brownies are just beginning to develop a crust, but there's still a bit of wobble in the middle.
Remove the brownies from the oven and leave to cool in the pan on a wire rack before slicing into 9 servings.
