Walnut Double-Decker Brownie Bars

 I adapted these slightly from a recipe by Abigail Johnson Dodge in Fine Cooking, Issue 89.  The original recipe calls for macademia nuts, and that's delicious, but given how hard they are to come by, I thought I'd try it with walnuts, and I like the texture and flavor of the walnuts a little better in this recipe.  I also used salted butter, since the walnuts are unsalted.  They freeze very well.

for the brownie layer:

·        Cooking spray

·        6 oz. (12 Tbs.) salted butter, cut into large chunks

·        1-1/2 cups granulated sugar

·        2-1/4 oz. (3/4 cup) unsweetened cocoa powder (natural or Dutch processed)

·        1/4 tsp. table salt

·        2 large eggs

·        1 tsp. pure vanilla extract

·        3-1/2 oz. (3/4 cup) unbleached all-purpose flour

For walnut coconut layer:

·        1/2 cup firmly packed light brown sugar

·        1-1/2 oz. (1/3 cup) unbleached all-purpose flour

·        2/3 cup light corn syrup

·        1-1/2 oz. (3 Tbs.) salted butter, melted

·        1-1/2 tsp. pure vanilla extract

·        2 large eggs

·        1-1/2 cups roughly chopped walnuts

·        1/3 cup sweetened coconut flakes

 

Position a rack in the center of the oven and heat the oven to 325ºF. Line the bottom and sides of a 9x13-inch baking pan with foil, leaving some overhang on the sides, and spray with cooking spray.

Make the brownie layer:

In a medium saucepan over medium heat, whisk the butter until it is melted. Remove the pan from the heat and add the sugar, cocoa powder, and salt. Whisk until well blended, about 1 minute. Add the eggs and vanilla and whisk until smooth. Add the flour and stir with a rubber spatula until blended. Scrape into the prepared pan and spread evenly. Bake until the top is shiny and dry-looking and the brownie springs back very slightly when pressed with a fingertip, about 20 minutes. (The brownie should not be completely baked.) Remove from the oven and put on a rack.

While the brownie layer is baking, make the walnut topping:

In a large mixing bowl, combine the brown sugar and flour. Whisk until well blended, breaking up any large clumps. Add the corn syrup, melted butter, and vanilla. Whisk until blended, about 1 minute. Add the eggs and whisk just until combined, about 30 seconds. (Don’t over mix or the batter will be foamy.) Add the nuts and coconut and stir with a rubber spatula until evenly blended.

Pour the walnut topping over the warm, partially baked brownie layer. Using a spatula, carefully spread the mixture into an even layer. Return the pan to the oven and bake until the top is golden brown, 37 to 40 minutes. Transfer the pan to a rack to cool completely.

Using the foil as handles, lift the rectangle from the pan and invert onto a work surface. Carefully peel away the foil. Flip right side up. Using a sharp knife, cut into 2x2-inch squares and then cut each square into triangles.

Make Ahead Tips

After both layers have been baked and cooled, the brownies can be cut, wrapped tightly, and frozen.
