Instructions
Make the cake
Preheat the oven to 350°F. Spray 3 8-inch round pans with nonstick spray. Line the bottoms with parchment paper cut into a circle to fit the pan. Spray the parchment paper with nonstick spray and dust the pan lightly with cocoa powder. Tap out any excess and set aside.
Whisk the flour, cocoa powder, baking soda, baking powder, and salt together in a medium bowl. Set aside.
Using a stand mixer fitted with a paddle attachment or a handheld electric mixer beat the butter and sugar together on medium-low speed until light and fluffy. Beat in the Nutella until well combined. Beat in the eggs, one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed. Beat in the vanilla.
With the mixer set to low speed. gradually add half the flour mixture, followed by the buttermilk, and then the remaining flour mixture. Beat just until combined. The batter will be thick.
Divide the batter evenly between the 3 prepared pans. Use an offset spatula to spread the batter all the way to the edges of the pan and smooth out the surface. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with only a few dry crumbs.
Cool the cake in the pans for 10 minutes. Invert the cakes onto a wire rack, peel the parchment paper off the bottoms, and allow the cakes to cool completely.
Make the frosting
Combine the egg whites, sugar, and salt in the bowl of a stand mixer. Set the bowl over a saucepan filled with 1 inch of barely simmering water. Whisk gently and continuously while heating the mixture. It should register 150°F on an instant-read thermometer. The sugar should be fully dissolved.
Transfer the bowl to the stand mixer and fit it with the whisk attachment. Beat on medium speed until the mixture is the consistency of shaving cream and cooled slightly, 1-2 minutes. (if the meringue is warm it will melt the butter.)
Switch to the paddle attachment and gradually add the butter, 1 tablespoon at a time, until smooth and creamy. (Only add the next tablespoon of butter once the last one has been completely mixed in.) Once all the butter is added, scrape down the sides of the bowl and mix on medium-high and beat until light and fluffy, about 30 seconds. If at any point the mixture looks curdled, don't panic. It will come together, just let it keep mixing.
Add the Nutella and continue to mix on medium until incorporated. If the frosting seems too thick, mix on medium-low speed to slightly deflate the egg whites. This will thin the frosting out.
Assemble the cake
Place one cake layer onto a serving platter. Add 1 cup of frosting and spread it to the edge with a spatula. Repeat with a second cake layer, topping it with 1 cup of frosting. Add the third cake layer and cover the top and sides of the cake with frosting.
Sprinkle with chocolate shavings if desired.
Notes
Buttermilk is required because there's a good amount of baking soda in this recipe. The acid from the buttermilk will neutralize the baking soda, this removes any off-flavor the baking soda can leave behind. If you don't have buttermilk or don't want to purchase it, you can make it by placing 1 tablespoon lemon juice or vinegar into a 1-cup liquid measuring cup. Then fill the cup with whole milk to make 1 full cup. Stir and let sit for 5 minutes before using. Do this for every cup of buttermilk called for in the recipe.
This cake is soft and delicate! It's best to cool the layers and chill them before frosting. Also, chill the frosted cake before slicing if you wish to have neat slices.
Dust the inside of the pans with cocoa powder to prevent the cake from sticking. The cocoa powder will blend in with the dark cake color, unlike flour.
Use room temperature ingredients! Cold eggs are difficult to blend into cake batter without overworking it. Cold buttermilk will cause the butter to resolidify and the batter will curdle.
For the very best results, weigh the ingredients. Small kitchen scales are relatively inexpensive.
