Melt butter. Beat together sugar, milk, egg, and almond extract. Combine baking powder and flour to the milk mixture. Mix in the melted butter until thoroughly combined. Coat the pan with vegetable spray. Fill the pan with the cake batter. Bake cake at 350° for 40-50 minutes or until a toothpick inserted comes out clean. Set cake pan on a rack to thoroughly cool. Do not try to remove while the cake is warm as it will crack. When cooled, place the pan upside down and tap. Sides can be loosened with a silicone or wooden tool. Do not use metal as it will scratch the pan.
When cool, sprinkle powdered sugar and almond slivers on the loaf. The pan I use is: 4.75 x 12.25 x 2 inches
