Toasting pecans or other nuts intensifies their flavor. To toast pecans, heat oven to 350°F. Spread pecans in ungreased shallow pan. Bake uncovered 6 to 10 minutes, stirring occasionally until light brown.
White chocolate is made from cocoa butter and adds a wonderful rich flavor to this cake. Find white chocolate in the baking section of the grocery store and use half of the 6 oz package (3 squares, 1-oz each) for the cake and half of the package (3 squares, 1-oz each) for the frosting. Melting the white chocolate in the microwave oven is quick and easy, but if you melt it in a pan on the stove, be sure to use very low heat to avoid scorching it.
