This is all done in one pan, so clean up is a breeze! Preheat oven to 350 degrees. Mix flour, sugar, poppy seeds, baking soda, and salt with a fork in an ungreased 9x9x2 baking pan. Stir in the remaining ingredients, except the powdered sugar. Bake 35-40 minutes or until toothpick inserted in center of cake comes out clean, and the top is golden brown. Remove from oven and cool. Sprinkle with powdered sugar. Makes 8 servings
