this recipe from allrecipes says it will puff up, but mine didn't. I followed what reviewer Gloria said and added 3 eggs instead of 1. Which also means I didn't do the egg white wash. Was this a mistake? almond bars 1 cup butter 3/4 cup white sugar 1 egg 1/2 cup almond paste 1 teaspoon almond extract 2 cups all-purpose flour 2 1/2 ounces sliced almonds Directions Preheat oven to 350 degrees F (175 degrees C). Cream butter in a large mixing bowl; gradually add sugar, beating until light and fluffy. Add egg yolk (reserve egg white), almond paste, and flavoring; beat until well blended. Stir in flour. Spread mixture in a 13 x 9 x 2 inch baking pan. Beat egg white (at room temperature) until foamy; brush over entire surface of dough, and sprinkle with almonds. Bake for 35 minutes or until lightly browned. Cool thoroughly, and cut into 2 inch squares. Store in airtight containers.
