Preheat the oven to 350˚F. Lightly spray an 11×7 baking dish.
Combine flours, icing sugar and ¾ cup butter in a food processor and pulse to mix until the mixture resembles a coarse meal.
Press the mixture into the prepared baking dish and bake for 20 minutes or until the edges are lightly browned. Let cool.
In a medium saucepan, melt the brown sugar, honey, ⅔ cup butter and milk, and allow to boil over medium heat. Remove from heat and stir in pecans. Pour mixture over crust.
Bake at 350˚F for 25-30 minutes or until golden and bubbly. Allow to cool before cutting into squares.
