Heat oven to 325°F. Spray 9-inch glass pie pan with cooking spray. Make pie crusts as directed on box for Two-Crust Pie using sprayed pie pan.
In medium bowl, mix walnuts, brown sugar, 2 tablespoons granulated sugar and the cinnamon. Pour and evenly spread 1/4 cup of the cooled melted butter over bottom of pie crust. Spread walnut mixture evenly over butter. Drizzle another 1/4 cup butter over nut mixture.
Top with second crust; seal edge and flute. Cut large slits in several places in top crust for steam to escape. Drizzle remaining 1/4 cup butter evenly over top crust.
Bake at 45 to 55 minutes or until golden brown. About 5 minutes before removing pie from oven, in 1-quart saucepan, cook honey and lemon juice over medium heat, stirring frequently, until mixture has a watery consistency.
Remove pie from oven; place on wire rack. Slowly pour hot honey mixture evenly over top of hot pie, making sure it seeps into slits in top crust. Cool at least 3 hours before serving.
Just before serving, in small bowl with electric mixer, beat topping ingredients on high speed about 2 minutes or until stiff peaks form. Spoon topping onto individual servings of pie.
