Joanie's Pesach Brownies

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease an 8x8 inch square pan.

Step 2
Melt the butter in a small saucepan over medium heat. Remove from the heat and stir in the unsweetened chocolate. Set aside.

Step 3
In a medium bowl, beat the eggs and sugar with an electric mixer for about 5 minutes. Reduce the speed to low, and pour in the chocolate and butter, then stir in the vanilla. In a separate bowl, stir together the matzo meal, potato starch and salt. Use a spoon to stir into the chocolate mixture until well blended. Mix in the walnuts or chocolate chips if using. Pour into the prepared pan and spread evenly.

Step 4
Bake for 25 minutes in the preheated oven, until the brownies are dry on top and begin to pull away from the sides.
