Cake
Prepare white cake as specified on box and divide cake mix between two 9-inch cake pans. Bake according to directions on box and cool for 30-45 minutes. Using the trifle bowl as a biscuit cutter, turn trifle bowl upside down and cut out a cake circle. This is the cake layer needed for the trifle. Repeat with the second 9-inch cake.
Pudding
Prepare the two packages of chocolate pudding as instructed on box and chill for 10 minutes or until set.
White Chocolate Mousse
Bring 1 cup whipping cream to a boil then add the white chocolate chips and decrease heat to medium and mix well until all melted. Cool white chocolate mixture in an ice bath for 20-30 min.
Before whipping the cream, add 2-3 drops of blue food coloring to 2 cups of cream to make a light blue hue. Using a hand held mixer, whip 2 cups of whipping cream until they reach stiff peaks. If the blue is not water color, add more to your liking. Fold the cooled white chocolate mixture into the whipped cream until well combined.
Assemble the trifle
Add a cup of chocolate pudding to the bottom of an 8-10 cup trifle bowl. Place one cake layer on top of the pudding and press cake down. Add another cup of chocolate pudding and then divide the white chocolate mousse and pour on top of pudding.
Here you have the option of adding the bunny Peeps as a decoration.
Add another cake layer and press layer down. Add the rest of the pudding and end with the whipping cream. Add blue food coloring streaks to create waves, but that is optional too.
Prepare the shredded coconut by adding 1-2 drops of green food coloring. Mix or toss well until the color is evenly distributed. This serves as grass. Add the grass as a topping to only a 1/4 of the whipped cream topping. Place chocolate-dipped Peeps in any way you desire.
Refrigerate for 2 hours to set or overnight and serve.
