This is an update to this recipe which was put up in September. I was making them again recently (January '11), and realized that there was an error in the ingredient section (probably, because as you can tell from the following text and photo, I had trouble reading my soiled recipe copy). The gram weight of flour was correct, but the corresponding cup measurements were not. If you have printed out this recipe, please check the updated ingredients.
In addition to this, if you read the prior post, you might have noticed that I wasn't happy with how tender the cupcakes were. This time around, I did some more experimenting and found that using bread flour instead of all-purpose made for a sturdier cupcake, and, I added another egg. This made the cupcakes firmer, also helped them rise higher and allowed me to get the cupcakes out of the liners more easily.
The following is the original post, with the appropriate corrections made to the ingredients.
----------------I've been trying to get this post done since the summer, but I had to grab a few minutes late at night to write up my recipes, because the days were filled with BCC Rally auction stuff. Now that the auction is over, I finally have time to post. But when I go back to see what I've done, I can hardly read the recipe because it's covered in chocolate!
That's why you need a CD-rom cookbook (mine, of course). Because instead of having a cookbook that's covered in chocolate, you can have a few recipe pages that you've printed off, and when you're done, you toss the messy things out! But now, on to the recipe!
The first time I made the cupcakes with Veronica and Jasmine (see Filled Chocolate Cupcakes, Part 1, I used a light version of my Chocolate Layer Cake. They were delicious, but a bit too tender. I think they were so tender because we used the maximum amount of milk (3/4 cup) and because we mixed them by hand. When I made them again, I used just a bit more than the minimum, and they came out much better - a little denser, which held up better for a pick-up type cake.
Makes 42 mini-cupcakes or 12 regular cupcakes
2-1/2 ounces semisweet chocolate, chopped
1 tablespoon oil
1 cup minus 1-1/2 TB (122 grams) bread flour, measured by fluffing, scooping and levelling*
2 tablespoons unsweetened cocoa powder
3/4 teaspoons baking soda
1/8 teaspoon salt
5 tablespoons (2.5 ounces) unsalted butter, cut into tablespoons and at room temperature
1/4 cup light brown sugar
1/2 cup sugar
1/2 teaspoon vanilla
2 large eggs, room temperature
1/4 cup + 2 tablespoons sour cream, room temperature
1/3 cup cup milk (skim or regular), room temperature
Preheat the oven to 350 degrees F. with an oven rack in the middle of the oven. Line muffin pans with liners.
Place the chopped chocolate and the oil in a microwave-safe container. Micro-cook on medium (#5) for 1 minute. Stir and then reheat in 15-second increments on medium power until the chocolate is melted.
In a small bowl sift together the flour, cocoa, baking soda and salt. Set it aside.
In a mixer bowl, combine the butter and both sugars. Beat on medium speed for 3-5 minutes until the mixture is uniformly smooth and creamy, and well aerated. Beat in vanilla. Add the eggs, beating for 1 minute after the addition of each egg, and scraping down the bowl a few times.
On low, beat in the sour cream and chocolate. On low, in 4 additions, beat in the flour mixture alternately with the milk, starting and ending with the flour. (This is actually easier to do by hand, because the batter doesn't tend to separate when you do it by hand, but it does make the cake more tender when done by hand).
Bake for 8-11 minutes for the minis, or 15-20 minutes for the full-size cupcakes, until a tester comes out clean. Set the tins on a wire rack until the cupcakes are cool, and then remove them from the pans.
I used whipped cream to fill the cherry-topped cupcakes, and Simple Vanilla Buttercream for the ones that look like Hostess cupcakes. The cream was easier to make, but the buttercream tasted far better. I've been making my buttercream a little thicker and sweeter lately, by adding a little powdered sugar to my basic recipe, but for this I wanted a filling that was very creamy - again so that it would be reminiscent of Hostess cupcakes. To do this, I used less than half of the powdered sugar as usual.
It’s ultra important that the butter be at the right temperature for this recipe to work, AND THE ROOM! If the room is too hot, the buttercream will never form. The room should be no warmer than 74 degrees - and colder is even better.
To get the butter the right temperature, cut it into tablespoons and let it stand on a cutting board until barely soft. Using your thumb, push down on each pat to flatten it into the board (it will still be very firm, and will split when you press down on it). In 3-5 minutes the butter should be ready. If you press down on it with your thumb, it should yield readily, but should not be soft and melty. If the butter is a little firm, it can always be beaten a little bit more, but if too soft, you’ll have to refrigerate it, and start over. I always aim for a little bit harder, rather than too soft.
2-1/2 sticks (20 tablespoons) unsalted butter, at cool room temperature
1 pound jar Marshmallow Fluff (this is a natural product containing only eggs, corn syrup and flavoring - so don't use another brand unless you check the ingredients)
1 teaspoon vanilla extract
2-3 tablespoons sifted powdered sugar
1-2 tablespoons corn syrup, to taste
2-3 tablespoons milk to soften the buttercream, optional
Now that the butter is at the proper temperature, scrape the butter into a mixing bowl and beat it until creamy (1 or 2 minutes.) Scrape down the bowl. Beat in the powdered sugar until fluffy. Add half of the Fluff, and beat on medium high until blended. Add the remaining Fluff, and continue to beat, on medium-high, for 2-5 minutes or until the frosting is fluffy and light and no longer marshmallowy.
This is what it should look like.
If the buttercream, does not form after beating for 5 minutes, place it in the refrigerator for 10 minutes, and then try and beat it again. After the buttercream forms, beat in the vanilla, corn syrup and milk, to taste.
Put the bag into a small glass, and then fill the bag
