This is the filling recipe I used, and its super quick and easy to make. I think it is best paired with plain white cake (since the it's already so sweet and you don't want to distract from the flavor). I used plain vanilla icing, but I suppose it wouldn't hurt to mix in some pureed strawberries to the icing.
I found the recipe here , but it's short so I'll just post it:
2 1/2 cups coarsely chopped fresh strawberries
1/2 cup sugar
2 1/2 tablespoons cornstarch
- Bring all ingredients to a boil in a heavy small sauce pan, stirring constantly and crushing berries slightly with back of spoon.
- Boil 2 minutes to thicken, stirring constantly (mixture will be slightly chunky).
- Pour into bowl and cool completely.
