Heat dates, coconut and half and half in a medium saucepan
over medium heat. Stir occasionally, until mixture boils and
thickens, about 15 minutes. Remove from heat and stir in vanilla.
Set aside to cool. Combine oats, flour, sugar, soda and cinnamon
in medium bowl and mix well. Pour melted butter over dry ingredients
and stir untill thoroughly moistened. Press about 3 cups of
granola mixture into bottom of 8x8-inch baking dish. Place
in refrigerator about 30 minutes to harden. Preheat oven to
350 degrees. Spread cooled date filling evenly over granola
base. Sprinkle remaining granola mixture (about 3/4 cup) over
date filling. Bake for 25-30 minutes or until granola topping
is slightly browned and crisp. Cool to room temperature before
cutting into squares.
