Step 1
Place rack in center of oven and heat to 350 degrees. Butter or lightly coat with cooking spray a 9-inch-by-9-inch baking pan. In a medium bowl, cream together butter, sugar and yolks until light and fluffy. Add liqueur, if using, orange zest and salt, mixing well.
In a clean medium bowl, beat egg whites with cream of tartar until stiff. Alternately fold in egg whites and flour into butter-egg mixture.
Turn batter into prepared pan and scatter blueberries evenly over top. Press down into batter with a spatula. Bake 30 to 40 minutes or until toothpick inserted near center comes out clean. Cut into 6 equal pieces. Serve warm or cold dusted with confectioners' sugar and blueberry sauce, if desired.
