Preheat oven to 350 degrees F. Liberally grease 2 9” cake pans with cooking spray. Set aside.
In a large bowl, prepare the cake batter according to package directions. Stir in the dry pudding mix to combine. Portion the batter evenly among the pans and bake as directed on the package, about 20 minutes. Cool completely.
Once cool, make your filling. In a large bowl, beat together the cream cheese, sugar and vanilla until creamy and light, about 1 minute. Beat in 1/3 of the Lucky Leaf Lemon Fruit Filling to combine. Fold in the Cool Whip topping and the lemon zest.
Place a cake layer on a pedestal or plate, top side down. Spread the cake with 1/3 of the Lucky Leaf Lemon Fruit Filling, spreading just about to the edges. Top with ½ of the Cool Whip mixture. Place the remaining cake layer on top, top side down. Spread with the remaining Lucky Leaf Lemon Fruit Topping and the remaining Cool Whip mixture. Garnish with raspberries.
