Preheat oven to 325 degrees F. Coat 3 separate 9"x13" baking dishes with cooking spray, line with wax paper and coat again with cooking spray. Stir almond extract into cake batter and divide batter evenly into 3 small bowls.
Stir red food color into one bowl,green food color into another bowl,and yellow food color into third bowl. Pour each color batter into a separate baking dish and spread evenly. The layer of batter will be very thin,that's okay.
Let cool completely. Place red layer top side down on a cutting board and remove wax paper. Spread half of raspberry jam evenly over top, then place yellow cake layer top side down over jam.
Place green cake layer on top,leaving wax paper in place. Place a baking sheet on top to gently press the layers together. Chill 1 hour then remove from refrigerator and remove wax paper. Spread a thin layer of melted chocolate over top and allow to harden slightly. Cut into 1"x2" cookies and serve,or cover and chill until ready to serve.
