Cookies and Cream Cake

Yesterday was my nephew's third birthday.  We had a small crawfish boil with my dad, and I of course offered to bake a cake.  Since my nephew had cookie cake on Friday and another cake today at his party with his friends, I decided to try out an idea I'd been brewing for a few days: a cookies and cream cake.  The idea was to have a layer of broken Oreo pieces on the bottom of each cake layer.  Much to my surprise, the cookies pieces floated to the top; perhaps if I'd stuck with my original idea of putting down a layer of whole Oreos, they would have stayed put.  

I wanted to make this cake with a light, whipped frosting; I searched around the web and couldn't find exactly what I wanted.  Most were glorified whipped cream.  I tried one recipe, only to have it end in utter failure, then I tried this recipe for The Best Whipped Frosting over at Can You Stay for Dinner?  It was definitely a winner and it has been marked as a go-to frosting recipe.  So creamy and light.  LOVE IT. 

 For the cake, I adapted the White Cake recipe from my trusty Better Homes and Gardens New Cookbook, using cake flour instead of all-purpose.  This resulted in a denser, spongier cake which hubby really enjoyed.

(My nephew actually didn't like the cake, though I'm fairly certain he didn't even try it.  Oh well! His rejection only broke my heart a little bit =D)

Cookies and Cream Cake

Cake 

• 1 package Oreo cookies
• 4 egg whites
• 2 1/4 cups cake flour
• 1 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp salt
• 1/2 cup butter, softened
• 1 3/4 cup sugar
• 1 tsp almond extract
• 1 1/3 cup buttermilk or sour milk

Frosting

• 1 cup milk
• 5 tablespoons flour
• 2 teaspoons vanilla extract
• 1 cup butter, at room temperature
• 1 1/4 cups granulated sugar (not powdered sugar)
• 1 cup crushed Oreo crumbs

For the Cake:

Allow egg whites to stand at room temperature for 30 minutes.  Meanwhile, grease two 9 inch round cake pans.  Preheat oven to 350F.

Break up half of Oreos, roughly into quarters.  Line them in a single layer, fitted as closely together as possible, in the bottom of each cake pan. 

In a small bowl, whisk together flour, baking powder, and salt. 

In a large mixing bowl, beat butter on high speed for 30 seconds.  Gradually add in sugar and vanilla, beating until well combined.  Beat for an additional 2 minutes, until the mixture is light and fluffy.  Add egg whites one at a time, beating well after each addition.  

Alternately add flour mixture and milk, mixing after each addition just until combined.  Pour into prepared pans.  

Bake for 20-30 minutes, or until a wood toothpick inserted near the center comes out clean.  (Note: the toothpick may come out chocolately, you just don't want it to come out with uncooked batter.)  Cool in pans for 10 minutes, then remove cakes and cool thoroughly on wire racks.  

For the Frosting:

In a medium saucepan, whisk one cup of milk with 5 tablespoons of flour. Heat over medium until the mixture begins to sputter, whisking constantly. Continue to stir as the mixture thickens. You will know it’s done when it reaches the consistency of thick cake batter, after about 7 minutes of heating and whisking. Stir in 2 teaspoons vanilla extract and set aside to cool COMPLETELY.

Now, in the bowl of a stand mixer fitted with a whisk attachment, or using a hand held mixer, beat 2 sticks of softened butter (1 cup) with 1 cup of granulated sugar until light, fluffy, and white in color, about 3 solid minutes of beating on medium-high speed. You want the sugar to be totally incorporated into the butter.

Be sure that the milk/flour mixture has completely cooled, and add it to the butter/sugar mixture. Beat all ingredients for about 1 minute on high speed, scraping down the bowl halfway, until they are smooth and well blended. 

Assembly:

Level the cakes, if necessary.  Pipe a thick border of frosting along the top of the bottom layer to dam the frosting filling.  Spread a layer of frosting evenly within the frosting border.  (You may make this layer as thick or thin as you like, depending on your preference.) Place the second layer of cake on top, and frost it.  Dust with Oreo crumbs.  (I did this by blowing crumbs out of my hand onto the cake, but this was MESSY.  One day I'll figure out how the professionals do it.)
