Birthday Oreo Layer Cake

A fanciful cake made up of both chocolate and confetti cake layers, whipped buttercream and Oreo frosting.  To top it off? A drippy chocolate glaze and sprinkles, of course!

I recently read a piece about how to be a better recipe writer.  In the piece was a quote from Ina Garten.  I can’t remember what it said exactly, but it basically stated that Ina tries to make the star ingredient of each of her dishes shine by adding the least amount of supporting flavours in order to make it taste amazing.  For example, if she were to make a plum tart, it better taste like plums - with maybe only a few spices and citrus to help bring out the natural flavours of the plums.  Nothing overly complex or unnecessarily complicated.

This cake it not that.

This cake takes all of our childhood dreams and crams them into one unapologetic layer cake.  This cake combines Oreos and confetti cake to make one epic birthday cake.  No, this cake is not for a child.  It is for my husband.  The man with a bigger sweet tooth than me.  And while he turned 33 years old this morning, you would never guess it if you could hear him giggling as he chases our screaming (with delight) toddler around the living room as I type this up.  May you always stay young at heart, Brett!  Happy Birthday - we love you!

Birthday Oreo Cake

Confetti Cake
from Layered

1 1/2 cups + 2 tablespoons cake flour
1 1/2 teaspoon baking powder
1/2 cup unsalted butter, softened
1 cup granulated sugar
1 1/2 teaspoons vanilla extract
3 egg yolks
3/4 cup milk
1/3 cup sprinkles

Pre-heat the oven to 350-degrees F.  Grease and flour two 6-inch round cake pans and set aside.

Sift together the flour and baking powder. Set aside.

In the bowl of an electric mixer, mix the butter on medium until smooth.  Add in the sugar and mix on medium-high until fluffy and pale in colour.  Stop the mixer and scrape down the bowl.  

With the mixer on low, add in the vanilla and egg yolks, one at a time.  Mix until incorporated.

With the mixer on low, add the dry ingredients and milk in alternating batches.  Mix just until the batter is incorporated.  Do not over-mix.  Fold in the sprinkles until combined.

Evenly distribute the batter into the prepared pans and bake for 24 to 28 minutes, or until a toothpick inserted into the center of the cakes comes out clean.  Let cool on a wire rack from 10 minutes before removing the cakes from their pans.

 

Chocolate Cake
1 1/4 cup all-purpose flour
1/2 cup unsweetened cocoa powder
1 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1/3 cup grapeseed or canola oil
1 cup granulated sugar
1 egg + 1 egg yolk
2 teaspoons vanilla extract
3/4 cup milk
1/2 cup hot coffee or hot water

Pre-heat the oven to 350-degrees F.  Grease and flour two 6-inch round cake pans and set aside.

Sift together the flour, baking powder, baking soda, and salt. Set aside.

In the bowl of an electric mixer, mix together the oil and sugar until combined.  With the mixer on low, add in the vanilla and egg, and egg yolk. 

With the mixer on low, add the dry ingredients and milk in alternating batches.  Mix just until the batter is incorporated. Stream in the hot coffee and mix until combined.

Evenly distribute the batter into the prepared pans and bake for 24 to 28 minutes, or until a toothpick inserted into the center of the cakes comes out clean.  Let cool on a wire rack from 10 minutes before removing the cakes from their pans.

Whipped Vanilla Buttercream
1 cup unsalted butter, softened
1/2 cup cream cheese, softened
5 1/2 to 6 cups confectioner’s sugar
2 teaspoons vanilla extract
4 to 6 tablespoons cream or milk

Using an electric mixer, beat the butter and cream cheese together on medium until smooth.  With the mixer on low, gradually add in the remaining ingredients.  Once the sugar begins to incorporate, turn the mixer up to medium-high and mix until light and fluffy (3 to 5 minutes).  Adjust the sugar and cream quantities until desired consistency is achieved.

Oreo Frosting
1/4 cup crushed Oreo cookies (about 6 cookies, filling removed) or plain chocolate wafer cookies
remaining vanilla buttercream

Fold in the crushed cookies into the remaining buttercream after the cake has been filled and the crumb coat has been applied.  If you wish to have colored Oreo frosting, be sure to add in the food coloring before the cookies to keep from over-mixing and the frosting from turning grey.

Chocolate Glaze
2 ounces chopped chocolate
4 tablespoons unsalted butter
1 tablespoons light corn syrup
pinch salt

Place the chocolate in a heat-safe bowl and set aside.

In a small saucepan over medium heat, melt down the butter and corn syrup.  Once hot, pour over the chocolate and let stand 30 seconds.  Add a pinch of salt and whisk until smooth.  Allow glaze to cool (but still runny) before dripping on the cake (about 10 minutes in the refrigerator).

Assembly

Once the cakes have cooled, trim them so that all of the layers are the same height.  Place one of the chocolate cake layers on a cake board or serving dish.  Spread on about 1/2 to 3/4 cups whipped vanilla buttercream.  Top with one of the confetti cake layers and repeat.  

Crumb coat the cake with the whipped vanilla frosting.  Reserve some plain vanilla frosting for piping details (if desired) before tinting the frosting.

Tint the frosting the colour of your choice then fold in the oreo crumbs.  Frost the cake with the Oreo frosting then chill until firm.  

Once the cake has chilled and the glaze has cooled, use a spoon to apply drips around the edges of the cake.  Fill in the center and spread with an offset spatula.  Add sprinkles before the glaze sets.  Use any remaining frosting to pipe swirly peak with a star tip in the center of the cake.  Top with more sprinkles, if desired.
