This is a recipe from the 70's or early 80's given to me. It melts in your mouth and makes a wonderful breakfast treat although most of the time it never lasted till breakfast in our house. The directions are sketchy on the original card, so let me know if you have questions.
1Step One: Preheat oven to 350. Measure first cup of sifted flour. Cut in butter till evenly blended. Add water and mix with a fork till dough forms. Pat into a ball and divide into 2 even parts. Pat into 2 strips 12x3 inches on an ungreased cookie sheet.
2Step 2: Mix butter and water and bring to a rolling boil in a small saucepan. Add almond extract. Remove from heat. Stir in flour immediately. When smooth and thick add eggs one at a time. Divide in half and spread on bottoms.
3Bake at 350 for 60 minutes. Frost with confectioners sugar and slivered almonds. ( I usually just sprinkle it with confectioners sugar when cool, but you can add the almonds right after baking.)
