This dessert is reminiscent of pecan pie. Cooking Light, April 2004. We didn't use coconut -- personal preference so increased the amount of chopped pecans. Didn't allow for chilling and cooling times.
Lightly spoon matzo cake meal and matzo meal into dry measuring cups, and level with a knife.
Combine matzo cake meal, matzo meal, and next 4 ingredients(cake meal throguh salt) stirring with a whisk; cut in 6 tablespoons butter with a pastry blender or 2 knives until the mixture resembles coarse meal.
Add 1 egg white, stirring until just moist; press into bottom of a 13x9" baking pan coated with cooking spray.
Bake for 20 minutes or until edges begin to brown; cool 15 minutes.
Combine 1-1/3 cups brown sugar and next 7 ingredients(brown sugar through 1 large egg) in medium bowl, stirring well with a whisk.
