My obsession and preference for feuilletine continues. I had to order a second container of the stuff to try out this recipe. At first I was skeptical of making the cake layers. The base was a cake mix and you know how judgy I am about grocery store box cake mixes. But there were enough added ingredients to it that I figured my snobby taste buds could deal.
Second moment of pause is when I baked these for only 20 minutes and the toothpick test came out almost completely clean. Did I overbake them? Were they going to be dry? Ugh. But thankfully, my paranoia was unfounded. In fact, I discovered the cake came out pretty well, was moist, had a good crumb and was appropriately chocolaty.
I simplified my version of the cake from the original blog several ways. I used the Nutella-feuilletine layer as the bottom layer as directed although I didn’t see the need to freeze it since it set just fine at room temperature. But I only used two of the three cake layers for the rest of the cake as I didn’t want the cake to be too tall. A towering cake looks impressive but once you start cutting it, things can go south really fast (ask me how I know). I didn’t cut each layer in half either but just went with them as is. That’s because more layers mean more frosting between the layers and I want more cake, not more frosting.
I also omitted the Nutella sauce. Instead, I frosted the feuilletine layer with straight Nutella then used the Nutella frosting as the filling between the cake layers and the overall cake. I also frosted the third layer and presented that as just a plain cake.
Despite all my simplifications, this was a really, really good cake. As in, when I brought it into work, I got a lot of compliments on it, getting stopped in the hall, people cursing me for ruining their diets (yeah, I’m that coworker), others sneaking in a second piece. I liked the contrast of the crunchy feuilletine layer on the bottom, the Nutella and chocolate combination of soft cake and I even liked the frosting. It was a bit too soft to use to pipe decorations (I tried and the results were disastrous) so I simply used it just as frosting and gave up on any fancy decorations.
Nutella Crunch Layer
1/2 cup semisweet chocolate, finely chopped
1 tablespoon butter
1/2 cup plus 1 tablespoon Nutella
2 1/2 cups (7 5/8 ounces) feuilletine
Cake
1 15.25-ounce box chocolate cake mix
1 cup all-purpose flour
1 cup granulated sugar
1/4 cup plus 2 tablespoons unsweetened cocoa powder
3/4 teaspoon salt
3 large eggs
1 1/2 teaspoons vanilla extract
1/2 cup vegetable oil
1 1/3 cups water
1 cup sour cream
Nutella Frosting
1 cup unsalted butter, room temperature
4 ounces cream cheese, softened
1 1/2 cups Nutella
1/2 cup plus 1 tablespoon (4 ounces) semisweet chocolate chips
1/2 cup plus 1 tablespoon (4 ounces) milk chocolate chips
1/2 cup confectioners' sugar
1/2 cup Nutella
- Make the Nutella Crunch Layer: Line an 8-inch cake pan with parchment paper then spray with nonstick cooking spray; set aside.
- In a large bowl, combine the chocolate chips and butter; melt over a double boiler set over hot water.
- Stir in the Nutella until well combined. Add in the feuilletine and gently stir into the Nutella mixture to coat.
- Transfer the mixture to the prepared pan and smooth into an even layer. Cover with plastic wrap then chill in the freezer until set and a firm layer, at least 30 minutes. Keep chilled until ready to assemble cake.
- Make the cake: Preheat oven to 350 degrees F.
- Line three 8-inch cake pans with parchment rounds and lightly spray with nonstick cooking spray.
- In a large bowl, whisk together the cake mix, flour, sugar, cocoa powder and salt until well combined.
- Add in the eggs, vanilla, oil, water and sour cream. Beat at low speed until all ingredients are combined, scraping down the sides of the bowl to keep even-textured. Beat for 1 minute longer.
- Divide batter equally between prepared cake pans. Bake for 20 to 25 minutes, or until a toothpick inserted near the centers comes out clean or with a few moist crumbs.
- Cool the cakes in the pans for 10 minutes then invert onto a plate, peel off the parchment paper and reinvert onto a wire rack to cool completely.
- Make the frosting: in the top half of a double boiler set over hot water, melt chocolates.
- In the bowl of a stand mixer fitted with the paddle attachment, beat the butter until smooth and creamy. Add in the cream cheese and beat until smooth and well combined, about 1 minute.
- Add in the Nutella and mix until completely incorporated. Add in the melted chocolate and mix until well combined. Cover with plastic wrap and keep in a cool place until ready to use.
- Assemble the cake: take the Nutella crunch layer out of the freezer, remove plastic wrap and parchment and place in the middle of a cake board or large cake plate.
- Frost the crunch layer with a thin layer of the 1/2 cup Nutella.
- Place the first cake layer over crunch later. Top with 1/2 cup of the Nutella frosting.
- Repeat with remaining layers. Frost entire cake with remaining Nutella frosting.
