Chocolate Cupcakes With Nutella Swiss Buttercream Frosting Recipes

Steps:

• For the cake: Preheat the oven to 350 degrees F. Line two 12-cup muffin tins with paper liners.
• Whisk together the cake flour, cocoa powder, granulated sugar, baking powder, baking soda and salt in the bowl of a stand mixer. Whisk together the buttermilk, coffee, oil, eggs and vanilla in a separate bowl.
• Pour half of the wet ingredients into the dry ingredients and beat on low speed just until combined. Scrape down the bowl then add the remaining wet ingredients and beat to combine. Scrape down the bowl and paddle. Increase the speed to medium and beat for a full minute.
• Fill the prepared cupcake tins 2/3 of the way full. Bake until a toothpick inserted in the center of each comes out clean and the top springs back when lightly pressed, 15 to 18 minutes.
• For the frosting: Melt the chocolate in a medium heatproof bowl set over simmering water in a medium saucepan. Remove from the simmering water and let it cool until room temperature, about 30 minutes.
• Beat the butter and salt in a large bowl with an electric mixer on high speed until light and fluffy, about 2 minutes. Reduce the speed to low, drizzle in the melted chocolate and beat until completely blended. Gradually beat in the confectioners' sugar, cocoa powder and vanilla. Increase the speed to high and beat until light and fluffy, about 2 minutes.
• Transfer the frosting to a pastry bag fitted with a large star tip. Decoratively pipe the frosting onto the cupcakes.

Steps:

• Beat butter with an electric mixer until fluffy. Add chocolate-hazelnut spread and blend lightly. Mix in cocoa powder until well combined.
• Add powdered sugar, 1 cup at a time, mixing well after each addition. Blend in vanilla. Add milk; mix to desired consistency.

Steps:

• In a stand mixer afixed with the paddle attachment, beat together the butter and powdered sugar on low until well-blended. Add the Nutella and increase the speed to medium. Beat for two minutes.
• Add the vanilla extract and salt and whip for an additional 30 seconds.
• Add the whipping cream and beat for about one minute, until the frosting lightens slightly in both color and texture.

Steps:

• FOR THE CAKE: Preheat the oven to 350 degrees fahrenheit. Line 2 muffin pans with 13 paper liners. In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt until well combined. Add the oil and sour cream and whisk until blended. Add the water in 1/4 cup at a time and whisk until combined. Whisk in vinegar and vanilla to blend. Add the egg and whisk until combined. Scrape down the sides of the bowl with a spatula to make sure all of the ingredients are well combined. Divide the batter equally among the cupcake liners. Bake for 18-20 minutes, until a toothpick inserted into the center of the cupcakes comes out almost clean (it's ok if a few crumbs stick to it, but should not look shiny). Cool completely on wire racks. FOR THE FROSTING: Combine the egg whites, sugar, and salt in a bowl (I used the bowl of my stand mixer). Place the bowl over a pan of simmering water. The bowl should not touch the water, nor should the water be at a rolling boil. It's the steam that's going to heat the egg whites, since we don't want scrambled eggs. Heat the egg white mixture until it reaches 145-150 degrees fahrenheit, whisking frequently so as not to get scrambled eggs. Remove the bowl from the heat, and whip the egg whites on medium high using the whisk attachment of your stand mixer. Whip the egg whites until they become fluffy and double in volume. The bowl should be cool to the touch (this will usually take several minutes). Turn the mixer down to medium low, and add the butter in one chunk at a time, until it has all been incorporated. If the mixture looks curdled at this point, this is normal. Just keep whipping for a few more minutes until it comes together. If the mixture looks soupy, you can add a few cubes of chilled butter, or stick the whole bowl in the refrigerator for about 15 minutes and then continue beating. Once the buttercream has become smooth, and the Nutella and beat until incorporated. Transfer the buttercream into an 18 inch piping bag and pipe onto the cooled cupcakes.

Steps:

• Combine butter and chocolate-hazelnut spread in a bowl and beat with an electric mixer on medium-high speed until creamy, about 2 minutes. Reduce speed on mixer to medium. Gradually add confectioners' sugar, 1/2 cup at a time, beating well after each addition and scraping down sides of the bowl as needed.
• After every 1 cup of confectioners' sugar, raise the speed of the mixer up to high and beat for 10 to 20 seconds. Add cream, hazelnut extract, vanilla extract, and salt. Beat until smooth.
