Step 1

Preheat the oven to 350˚F. Line an 8×8 inch pan with aluminum foil, leaving a 2-inch overhang. Set aside.

Step 2

Place the prunes and the water in a food processor and process until smooth.

Step 3

Boil 5 cups of water and pour into a medium bowl.

Step 4

Place the chocolate chips and butter into a smaller bowl, and place it into the bowl full of water. Mix the chocolate chips and butter until the mixture is smooth, making sure not to let the water mix in with the chocolate mixture.

Step 5

Remove the chocolate mixture from the water bath. Immediately whisk in the sugar, egg, egg white, prune puree and vanilla until smooth.

Step 6

In a separate bowl, mix together the flours and cocoa powder. Stir in the chocolate mixture until fully incorporated.

Step 7

Pour the batter evenly in the prepared pan. Bake for around 30 minutes, or until a toothpick inserted comes out with a few moist crumbs. Let cool completely in the pan. Using the foil, remove the brownies from the pan, and cut into squares.
