Back to the Future Cake (aka Jailbird Joey Cake)

My friend was throwing a Back to the Future viewing party and asked me to recreate the cake featured at the beginning of the movie. You know, the Jailbird Joey cake?

I did my best:

I used the delicious recipe that's below and my own sub-par art skills. Which were oddly perfect for this particular task.

Vanilla Cake

2 sticks unsalted butter (at room temperature) (plus more for pan)
2 1/2 cups all-purpose flour (plus more for pan)
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1 teaspoon salt
1 1/2 cups sugar
2 eggs
3 egg yolks
2 teaspoons vanilla extract
1 cup low-fat buttermilk

-Preheat oven to 350 degrees. Butter and flour your 13-by-9-inch baking pan. In a medium bowl, whisk flour, baking powder, baking soda, and salt.
-Beat butter and sugar with an electric mixer in a large bowl until fluffy. Then beat in eggs and yolks one at a time, then the vanilla. Next, take turns adding and beating in flour mixture and buttermilk. Mix until all the ingredients are combined.
-Pour batter into pan and smooth top. Bake 25 to 35 minutes until cake pulls away from the side of the pan. Let cool for 10 minutes. Run knife around edge and invert cake onto a wire rack. Cover with desired frosting.
