Cake: Bake the Lemon Lovers Pound Cake and cool, then cube.
Lemon Simple Syrup: In a small saucepan over medium-high mix the granulated sugar and lemon juice together. Stir until the sugar is completely dissolved then set aside to cool.
Filling: In the bowl of a stand mixer fitted with the whisk attachment, whip together both packets of Dream Whip [The box contains 2 envelopes or packets, use both] with 2 cups of cold milk. Whip for 5 minutes or until soft peaks form.
To the bowl add both packages of lemon pudding mix and the remaining 1 cup of milk. Whip for 2-3 minutes on medium high speed until thickened.
Assemble: Divide the cubed cake in half. On the bottom of the bowl begin with a layer of cubed cake. Brush the cake with 1/2 of the lemon syrup.
Add a layer of lemon pudding mixture and 1/2 of the whipped topping. Repeat with cubed cake, brush with lemon syrup, lemon pudding mixture ending with whipped topping.
Garnish: Sprinkle the top with grated white chocolate and garnish with lemon slices and fresh mint, if desired. (You may also opt to add some fresh lemon zest to the top!)
Chill thoroughly for at least 4 hours prior to serving.
