4th of July Cake!!!

Happy 4th of July!!!
What are you doing for Independence Day? Well, I'll tell you what I'm doing: I'm making this AWESOME cake as I've done every year since I was about 6 years old. (I'm also dressing up my cat, and the photos from that event are on my other blog: chicothefatcat.blogspot.com)

The recipe is so simple, which is why I'm going to post it right here on my blog! You may have made this cake before, in which case you should definitely: A) make it again this year using this quick and easy recipe, or B) tell friends and family about the recipe (and my blog) so they can use it, and enjoy it, too!

INGREDIENTS
-Yellow cake mix
-13x9 cake pan
-Ingredients listed on cake box (water/eggs/oil etc)
-30 blueberries
-about 10 strawberries
-1 cup whipping cream

DIRECTIONS
1. Prepare the yellow cake as is instructed on the back of the cake mix box.
AS THE CAKE BAKES:
2. In a deep bowl, whip the cream on high speed until thick and fluffy using electric hand beater or built-in-bowl electric mixer. Add 1 tbsp of sugar as you whip the cream. Refrigerate in bowl covered with plastic wrap.
3. Wash the blueberries and strawberries.
4. Prepare the strawberries: cut off the hulls (green leafy part) so that they look like this: Then, place the strawberries on the cutting board flat side down and slice them into fourths.
5. Once the cake is out of the oven, let it cool completely in the pan (sorry, this should take at least 2 hours :P)
6. After the cake has cooled, take the whipped cream out of the fridge and stir it a few strokes so it doesn't settle.
7. Plop the whipped cream on top of the cake in big spoonfuls, then evenly smooth it around in as few strokes as possible using a rubber spatula such as these ones:

8. In the top left corner of the cake (on top of the whipped cream), arrange the blueberries in a 5x6 array. They should take up about 1/4 of the cake.
9. Arrange the strawberries atop the cake on their sides so that they resemble the red and white stripes of the American flag.
10. Refrigerate for at least half an hour so that the cream gets a little firm. Snap a picture and enjoy.
