First things first, the cupcake. In this case, really more of a vessel for the chocolatey-hazlenut goodness than the main attraction.
Now, don't freak, but I used a mix. And I'm not ashamed. I love cake mixes, and I don't care what anyone says. Yes, I often make everything from scratch, but it isn't always necessary. Cake mixes are a great base and offer one amazing quality everyone wants in their baking...consistency. Ah, yes. Measuring dry ingredients accurately is essential, as anyone on Food Network will tell you (every single time they bake anything...end rant) and cake mixes are just so freaking perfect. Judge if you will, but don't knock it until you try it.
Here are the key players:
The Cake
I used Betty Crocker Triple Chocolate Fudge mix. I'm a fan of Betty Crocker, but I've been known to use Duncan Hines and Pillsbury (hello, funfetti!) too. Pretty much any chocolate cake mix will work here. I also used Plugra European style butter (available at Wal-mart), organic milk (it matters to me but is not strictly necessary) and Rodelle vanilla (my favorite brand, big bottle is awesomely cheap at Target).
Mix the cake mix with:
3 eggs
5 tablespoons softened butter
2 teaspoons vanilla
1/2 cup sour cream
3/4 milk
Beat with a hand mixer at medium speed for 2 minutes.
*Note: This combination of ingredients does not work with vanilla or yellow cake mixes. I've tried it.
Scoop into lined cupcake tin and bake at 350 for 15-20 minutes. I turn the pan halfway through to ensure even baking. Cupcakes are done when they spring back to a light touch. Don't over bake, and keep in mind they continue to bake slightly after coming out of the oven. I take them out of the pan quickly and transfer to a cooling rack.
The Filling
Oh yes, these are filled cupcakes. If it were up to me, every cupcake would have filling. Maybe this one. This is a very basic, very simple filling but it is oh-so-good.
1 small jar Nutella
(I believe there are other brands of chocolate hazelnut spreads, but I've never used anything but the original)
1/2 cup softened butter
2 teaspoons vanilla
1/4 powdered sugar
Pinch salt
Whip together the nutella and butter until fluffy. Add the vanilla and sugar and mix well. To be completely honest, these measurements are not set in stone. If you don't like your filling too sweet and more hazelnutty, feel free to leave out the sugar. Or if you want it extra sweet, add some more. Taste is the key here. I taste everything I make and adjust as needed. Trust your taste buds.
I put the filling in a piping bag, cut the centers out of my cupcakes, and filled. I've found a sharp knife is the best way to core a cupcake. You can go as deep or as shallow as you like, depending on how much filling you want your cupcakes to have. I've seen and used those specifically made cupcake plungers, and they're just a gimmick. You also can just spoon in the filling if you don't have/don't want to use a piping bag.
Chocolate Ganache Frosting
My husband is in love with this frosting. I'm afraid it's turning into a full-blown affair. And there's no one to blame but myself. It's smooth, it's sweet, and SO chocolatey. This is not a traditional ganache recipe (which is almost always just chocolate and heavy cream). If you already have a beloved chocolate ganache recipe, I will not hate you for using it. I used chocolate, 2% milk and butter. It's fluffier and lighter than a regular ganache and therefore in my opinion works better as a frosting.
2 bars (8 oz) semi-sweet baking chocolate
1 cup milk
1/3 cup softened butter
Heat the milk and butter together in the microwave or a sauce pan and pour over chocolate. Stir until smooth. Place in the refrigerator and stir every 10-15 minutes until completely cool and set. You can also put it in the freezer if you are in a hurry, but stir it often. The sides will start to freeze quickly and it will be difficult to mix otherwise. I used my hand mixer to make it slightly fluffier. You can also add powdered sugar and vanilla if you are looking for a sweeter flavor, which I did. I added a couple tablespoons of sugar and a teaspoon of vanilla. Pipe onto your cupcakes. I used a Wilton 1M star tip, piping a ruffle along the outside edge and then filling in the center. I then topped them with a Ferrero Rocher chocolate and a little bit of chocolate shavings.
Some Additional Thoughts:
The filling can easily be used as the frosting! The 3rd cupcake on the right was frosted with the filling (it is slightly shinier than the others) and it was just as good as the others, although this adds a lot more hazelnut flavor than using the ganache frosting.
I am not a scientific baker. So much of what I make I do by taste, and so you may need to adjust these recipes to suit your own preferences. With the filling and the frosting (not the cake recipe) don't be afraid to change the amounts. If you like it sweeter, add more sugar! I can't stress enough how important I think it is to taste everything.
Happy Baking!
