The flavor and texture of these chewy confections are even better if they are allowed to rest overnight.

　　

Ingredients

6 ounces fine-quality or premium white chocolate, chopped

　　5 tablespoons unsalted butter, cut into pieces

　　2 large eggs

　　1 cup sugar

　　1 teaspoon vanilla

　　1 cup all-purpose flour

　　1/2 teaspoon baking powder

　　1/4 teaspoon salt

　　1/2 cup macadamia nuts, toasted lightly and chopped coarse

　　1/2 cup semisweet chocolate chips

　　

Step 1

Preheat oven to 350°F. and butter and flour a 9-inch square baking pan, knocking out excess flour.

　　

Step 2

In a double boiler or metal bowl set over a saucepan of barely simmering water melt white chocolate and butter, stirring, until smooth and remove top of double boiler or bowl from heat. Cool chocolate mixture to room temperature.

　　

Step 3

In a large bowl with an electric mixer beat eggs, sugar, and vanilla until thickened and pale and beat in white chocolate mixture. Into a bowl sift together flour, baking powder, and salt and beat into chocolate mixture just until batter is combined well. Stir in nuts and chocolate chips and spread batter evenly in pan.
