Double Chocolate Potato Brownies

 

• 3/4 cup butter
• 3 1-ounce unsweetened chocolate squares
• 1 1/2 cups granulated sugar
• 4 eggs, at room temperature
• 1 teaspoon vanilla
• 1/2 teaspoon salt
• 1 cup mashed white potatoes (unseasoned) at room temperature, about 2 medium potatoes
• 1 cup all-purpose flour
• 3/4 cup semi-sweet chocolate chips
• 3/4 cup walnuts, chopped

Heat oven to 350 degrees. Melt butter and chocolate in medium saucepan over low heat until smooth.

Let cool 15 minutes. Stir in sugar, eggs, vanilla and salt. Stir in potatoes until smooth. Add flour and stir to combine. Pour into a greased 13-by-9-inch baking pan. Sprinkle with chocolate chips and walnuts. Bake until brownies are firm when lightly touched, 25 to 30 minutes. Cool on rack. Cut into squares to serve.
