1- 8 ounce can almond paste
1 1/2 cups (3 sticks) unsalted butter, at room temperature
1 cup of sugar
4 eggs, separated
1 teaspoon almond extract
2 cups sifted all-purpose flour
1/4 teaspoon salt
10 drops green food coloring
8 drops red food coloring
12-ounce jar apricot preserves
8 ounces semisweet chocolate
Heat the oven to 350 degrees F. Grease three 13 x 9 x 2-inch baking dishes; line with waxed paper; spray the paper with cooking spray.
Break up the almond paste in an electric mixer bowl with a fork. Add butter, sugar, egg yolks and extract and beat with the mixer until fluffy, 5 minutes. Beat in the flour and salt.
Beat egg whites in a separate bowl until stiff peaks form. Stir into the almond mixture with a wooden spoon, using turning motion similar to folding.
Remove 1-1/2 cups batter; spread evenly into one of the prepared pans. Remove another 1-1/2 cups batter to small bowl; tint green with coloring. Spread into the second pan. Tint remaining 1-1/2 cups batter red. Spread in the remaining pan.
Bake 15 minutes or until edges are lightly golden; cake layers will each be 1/4 inch thick. Immediately remove cakes from the pans onto large wire racks. Carefully peel off waxed paper. Cool.
Place red layer on upturned jelly roll pan or large platter lined with foil. Heat preserves; strain. Spread half of the strained preserves over the red layer. Top with a white layer. Spread with remaining preserves. Cover with a green layer, top side up.
Cover with plastic wrap. Weigh down with a large wooden cutting board, heavy flat tray or large book. Refrigerate overnight.
Melt chocolate in top of a double boiler over hot water.
Trim off the uneven cake edges with a sharp knife. Frost the top layer with half of the melted chocolate. Let chocolate dry. Turn the rectangle over and frost with the remaining chocolate. Let the chocolate dry. Cut the cake crosswise into 1-inch-wide strips. Cut each strip into 1-inch pieces. Makes about 6 dozen. Store in a container in the refrigerator. Cookies freeze well.
