Put 2 cups flour and ½ cup powdered sugar into the cuisinart with regular blade. Combine them for 30 seconds.
Cut up cold butter into smaller chunks and put into Cuisinart, ½ half at a time. Pulse until butter and flour becomes like sand.
Press this mixture into a 9" x 13" x 2" baking pan.
Bake the shortbread crust for about 25 minutes at 300 degrees until lightly browned.
Just before shortbread is done combine the rest of the ingredients in a bowl.
Pull out crust and out this layer onto the top and spread out with a spatula.
Put back into oven and raise the temp to 350 degrees.
Bake at 350 for 25 to 30 minutes. Should be a bit firm to the touch and lightly brown.
