My recipe book: Betty crocker extra moist chocolate marble cake with icing

Hi,
This weekend we were expecting our friends at home.
I prepared a cake with instant cake mix for the first time.
I cooked the cake on friday night to set it cool all night long.
It came so well that my husband who tries to be away from sweets couldnt stop from eating.
The most delicious is the topping and the icing.

Betty corker marble cake:

1 box Betty corker vanilla instant cake mix
Chocolate sauce- around 1/4th cup
Strawberry flavored milk powder mix - 3tblspoons.
Heavy whipping milk - 1 pint
chocolate fudge icing 2 tablespoons
Sugar syrup.
Strawberry sauce.

Mix the batter according to the instructions adding 1/4th cup of oil, 1 1/2 cups of water, 3 egg whites.
Be sure that there are no lumps.

Divide the batter in to two parts.
Mix the strawberry powder mix in half the batter.
Leave the other for chocolate marble.
Greese the aluminum tray with oil and dust all purpose flour.

Fill the strawberry and plain batter in two 6" baking pan.
In one of the pan, top the cake batter with 4 tablespoon of chocolate sauce and turn the spoon in the batter in s shape.
In the other pan, fill the strawberry batter.
Bake them for 475 degrees in the oven for 20 min.
Remove them from oven and cover the lids with an aluminum foil.
Set it to normal room temperature.

Cut the cake at sides and at the top to make it a perfect size.
After it cools, wet it with sugar syrup.
On the chocolate marble cake, top it with chocolate fudge icing.
Put the strawberry cake on the marble cake after icing.

Beat the heavy whipping cream and add 1/4th cup sugar.
You can even add extra sugar for more sweetness.

Set in the the fridge for 5 hours till the icing will be a lil tight.
First start with icing the sides.
After the sides completes, apply on the cake.
Take a icing pipe and fill it with chocolate frosting and border the cake on the bottom.
Apply strawberry icing and apply the borders on the top.
You can leave the cake without decorations.
