I'm sorry I didn't check back to see that you wanted this recipe,
I did this for a wedding and it turned out great,
Here is the recipe
1 pkg. butter cake mix
1pkg. 8 oz. softened cream cheese
4 large eggs
1/2 c. water
1/2 c. oil
1/2 c. sugar
1 t. vanilla
1 t. almond flav.
2/3 c. strawberry filling ( I buy mine in the sleeve)
mix all of the above ingredients, except the strawberry filling, one minute on low, then 3 min on medium, and pour into pan. Then dollop the strawberry filling randomly on the cake and swirl with a knife, don't put too much on, so you can see white cake and strawberry definition. It depends on the cake size how much you will need, for a 12" cake, I used about a 2/3 cup.
