Brooklyn Blackout Whoopie Pies

Brooklyn Blackout cake has to be one of my favorite cakes. It’s a triple chocolate lovers dreams come true. Chocolate cake, chocolate filling (usually a chocolate pastry cream), and a chocolate buttercream to round out the quick version of this delicious cake. That soon becomes a whoopie pie!

And if that wasn’t enough chocolate for you, its garnished with cake crumbs on the top just in case you needed a little more chocolate!

My First Dance

When I first started my cake business, the Brooklyn Blackout Cake was my very first order. Many of my customers had never heard of it. To be honest, I had never heard of it either until I was going through a cookbook of mine where I came across it.

A Little History

Boy, am I glad I did, it’s just an amazing cake. I was so intrigued by it I wanted to read up on the history of it. Named after the blackouts during WW2 , you can read it here.

Regretfully, I don’t make it as frequently as I use to but it’s definitely in the recipe box for special occasions. Being inspired, I decided to adapt it into a delicious chocolate whoopie pie.

Devils food cake is where I start, making a delicious foundation in which to build this delicious treat.

Baked and cooled and they are ready to fill.

NOTE** Reserve two whoopie cookies, crumble them up into fine crumbs and set aside for the topping.

Filling

Chocolate Buttercream is what I use for the filling. Typically, I know that the usual filling for this type of cake is a chocolate pudding or pastry cream. The buttercream gives more stability as the other fillings tend to be a bit more lose.

This is a simple and delicious buttercream that comes together easily.

Chocolate buttercream

  • 1 stick unsalted butter, softened
  • 1/2 cup shortening
  • 4 cups powdered sugar (or 1 pound)
  • 1 tsp vanilla
  • 2 TBS milk

In a stand mixer with a paddle attachment, cream the shortening and butter till creamy. Add the powdered sugar, vanilla, and milk and slowly mix. Once all combined, turn mixer up to medium high and mix about one minute till creamy.

The buttercream is put into a pastry bag and ready to fill. Alternatively, you can use a small offset spatula to spread the filling on the bottom of each sandwich duo.

Topping

Once you have the cookies sandwiched together, its time for the fun.

You will need the following:

  • Chocolate Candy Melts or Chocolate Almond Bark (chopped)
  • Reserved crumbs from two whoopie cookies

Microwave the candy melts till they are smooth and drizzling consistency. Place in a piping bag and drizzle over each pie. You can also drizzle the candy melts with a spoon.

While the chocolate is still warm, sprinkle each pie with some of the chocolate cake crumbs. When the chocolate cools, the crumbs will adhere.

These by far, are my families new favorite. Totally to die for!
