Start by making your strawberry cake according to the instructions on the box. Next, blend the frozen strawberries with 2 tablespoon water and 2 tablespoon Sugar. Using the end of a wooden spoon, poke holes in the cake after it has cooked and cooled. Pour the blended strawberry mixture into the holes of the cake. Next, mix together the vanilla pudding and milk. Fold in the Cool Whip and spread over the cake. Top with fresh strawberries for garnish. Refrigerate for 2-4 hours! Enjoy!
