Layered Chocolate Cake - cooking recipe

Ingredients

1 (18 1/4 ounce) package German chocolate cake mix
1 1/3 cups water
3 eggs
1/3 cup canola oil
1 (3 ounce) package vanilla pudding mix (cook-and-serve)
1 teaspoon unflavored gelatin
2 cups milk
1 (8 ounce) package cream cheese, softened
1/2 cup unsalted butter, softened
1 1/2 cups powdered sugar
3 tablespoons baking cocoa
1 teaspoon pure vanilla extract

Preparation

Preheat oven to 350 degrees F, then grease a 15\"x10\" baking pan.
In a large bowl, stir together cake mix, water, eggs & oil until well combined.
Pour into the prepared pan & bake 23-25 minutes or until a toothpick inserted near the center comes out clean.
Cool in the pan on a wire rack.
In a large saucepan, combine pudding mix, gelatin & milk, cooking according to the package directions for pudding. Cool.
When cake has cooled, cut it into three 10\"x5\" rectangles, placing one on a serving platter & spreading half of the pudding mixture over the top of it. Repeat this layering, then top that off with the 3rd layer of cake.
In a large bowl, beat cream cheese & butter until fluffy, then beat in the sugar & cocoa & then the vanilla until smooth.
Frost top & sides of the cake. Store in the refrigerator.
