Once the cake layers have fully cooled, level both layers by cutting the top bump with a serrated knife. Place one of the layers on your serving plate.
Brush the cut side with the syrup, this helps keep the cake moist. Add about ¼ inch in thickness of frosting on top and spread evenly. Add halved strawberries and top more frosting, just enough to cover the strawberries.
Take the other cake layer and brush the cut side with syrup. Place the cake, cut side down on top of the frosting. If you still have syrup left, brush the top side with it.
Prepare a piping bag with a round tip (I used a Wilton 2A). Transfer about ⅓ cup of the whipped cream frosting and set aside. Completely cover the cake with the remaining whipped cream frosting. To get nice smooth sides, take an offset spatula edge against the side and rotate the cake around.
Take the prepared piping bag and make little whipped cream peaks near the edge of the cake. Take the whole strawberries and place three on one half of the cake and the other three on the other side, to match the in-game item.
Take the chocolate birthday plaque and place it between the two sets of strawberries. It will rest on the back set. I recommend letting this cake sit covered in the refrigerator for at least 1 hour before cutting into it. It can be stored in the refrigerator for up to 3 days.
