PREPARATION:
Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius).In a bowl, combine the flour and sugar for the crust mixture.Cut in the cold butter until the mixture becomes crumbly. Set aside 1 cup of this mixture for later use.Press the remaining crust mixture into the bottom of a well-greased 9×13-inch baking dish.Bake the crust for 15 minutes until lightly golden.In another bowl, blend together the filling ingredients until well combined. Spread the filling over the pre-baked crust in the baking dish.Sprinkle the reserved crust mixture over the filling, creating a crumbled topping.Bake the bars for 1 hour, or until the top is golden and the filling is set.Allow the bars to cool for 15-20 minutes.In a separate bowl, beat together the icing ingredients until smooth and well combined.Drizzle the coconut-infused icing over the bars, adding more half and half if needed to achieve the desired consistency.Slice the bars into individual servings and serve.
