CUSTARD THUMBPRINTS COOKIE: 1/2 C. Sugar 1C. margarine-softened 1 teaspoon Vanilla 2 Egg yolks 2 1/4 C Flour 1 teaspoon Baking Powder FILLING: 1 Tablespoon Sugar 1 Tablespoon Flour 1/4 teaspoon Almond Extract 1/2C. Whipping Cream 1 Egg yolk- slightly beaten In medium bowl, cream sugar, margarine, vanilla, and egg yolks until light and fluffy. Lightly spoon flour into measuring cup; level off. Gradually add flour and baking powder; mix well. Chill 30 mins. In small saucepan, mix sugar, flour, and almond extract. Gradually add cream; cook over low heat until smooth and thickened, stirring constantly. In small bowl, blend 2 Tablespoons HOT mixture into egg yolk. Return to saucepan; blend well. Cook just until mixture bubbles, stirring constantly. Cool. Heat oven to 350. Shape dough into 1" balls; place, 2" apart on ungreased cookie sheets. With thumb, make imprint in center of each cookie; fill with 1/2 teaspoon filling. Bake at 350 for 11-14 mins. or until light golden brown around the edges. Store in frig. I skip the filling and use Apricot Jelly instead. Can put the jelly on before baking to have it firm or after baking if you'd like it soft.
