Rainbow cookies

I grew up in New Jersey really close to NYC so wonderful cookies & pastries were always available. Now that I live in Texas, I can't get them at all. These are one of my fav cookies so I had to learn to make them myself. Yum!

8 oz pre made almond filling
1 cup sugar
4 eggs
1 1/2 cups butter
1 tsp almond extract
2 cups flour
Green food coloring
Red food coloring
12 oz seedless raspberry preserves
4 oz semi sweet chocolate
2 tbsp milk

In a bowl mix almond filling, sugar & eggs until smooth. Add the butter & almond extract & mix again. Add the flour & mix until smooth. Divide the dough into 3 equal parts. Set one portion aside. Add the green food coloring to one portion & mix until consistent; repeat with red color for 3rd portion.
Grease bottom & sides of three 9x12 pans. Pour one color into each pan. Bake for 15 minutes in preheated 350 degree oven. Take out & let cool.
Invert the pan with green cake out onto aluminum foil lined cookie sheet. Spread 3 tbsp of preserves on the layer. Place yellow layer on green layer. Put preserves on that layer followed by red cake. Do not put preserves on red layer. Place aluminum foil on top layer & place a heavy book on the foil. Refrigerate overnight.
The next day, place the chocolate & milk in saucepan over low heat & stir until smooth. Spread chocolate over top layer. Let cool in fridge for at least an hour before cutting into 1 inch squares.
