Chocolate Pistachio Cake

So today I was looking at our daily To Do list, which we make every day at the bakery. And, one of the items on there was package Pistachio Bark (that was made the previous evening). So I pulled it out of the freezer, only to find that it was not made correctly and the white chocolate was missing... We hate wasting things at the shop and this chocolate was still good, it just wasn't what it was supposed to be.

So, we brainstormed about what to do with this Chocolate Pistachio Bark. We decided we could make an easy pistachio cake recipe and use the bark with it. So we started with a Chocolate Cake with Pistachio Frosting. And then we added more... This rich chocolate cake is filled with pistachio buttercream which tastes of just pure pistachio cream, chopped pistachios, chocolate ganache and is decorated with the pistachio bark. It's also colored naturally with ColorKitchen food dyes, which have no artificial colors. This cake is perfect for any end of summer celebration.

Method Make the Chocolate Ganache ahead of time, you can store in the fridge if you make the day before. Just make sure it’s at room temperature before using on the cake.

To make the Chocolate Pistachio Bark: Line a baking sheet with parchment paper. In a double boiler, add 226 grams of the dark chocolate and melt until it reaches 115°F on a chocolate thermometer. Remove from heat and add in the remaining dark chocolate and stir to combine completely, allow temp to cool to 91°F. 

Spread the chocolate onto the parchment paper. Top with chopped pistachios. Place in the freezer until ready to use.

To make the batter: Preheat the oven to 350°F. Line three 6-inch cake pans with parchment paper.

In the bowl of a stand mixer fitted with the paddle attachment, add the butter, cane sugar and vanilla extract. Mix on low until all ingredients are combined. Add the eggs and heavy whipping cream and mix on low until combined.

In a separate bowl, add the cake flour, cocoa, sea salt and baking powder and whisk together. Add the cake flour mixture into the butter mixture, mix on low until combined into a smooth cake batter. Measure batter evenly into each cake pan, about 233 grams each.

Bake for 20 minutes, or until a wooden pick inserted in center comes out clean. Allow to cool completely in the baking pans.

To make the frosting: In the bowl of a stand mixer fitted with the paddle attachment, add the butter, powdered sugar, pistachio extract, green dye and water. Mix on low until all ingredients are combined, then speed mixer up to high for 1 minute or until light and fluffy.

On a cake stand or cake spinner, place the first layer of cake and spread frosting evenly. Sprinkle some of the chopped pistachios and top with Chocolate Ganache, top with second cake layer and repeat this process.

Crumb coat the outside of your cake and then frost it smooth, find a how to here.

Put the remaining frosting in a piping bag with Ateco tip #96.Pipe rosettes around the top of the cake. Fill inside of the rosettes with chocolate ganache.

Remove the Chocolate Pistachio Bark from the freezer and break into pieces. You’ll want smaller pieces for the side of the cake and larger pieces for the top.

Place shards of the Chocolate Pistachio Bark on top and on the sides of the cake.

Store in a cake dome for up to 3 days.
