These cupcakes are supposed to be like those Hostess cupcake dealies you find at the convenience store. One huge difference, though, is that these have a shelf-life of a couple days rather than a couple decades — come on, you’ve seen those Twinkie exposés. I don’t recall ever actually having the convenience store cupcakes, but the picture in my cookbook just looked too fun to pass up.
For materials, these are supposed to be the jumbo cupcakes requiring the silly jumbo cupcake pan. My common sense told me it’d be just the same, but the Martha in me sprung for the jumbo pan (about $4.50 at Hobby Lobby — with the weekly coupon — if you’re interested). You’ll see later why I hesitated to use smaller cupcake pans…
Enough talk, let’s get baking. Start by combining the dry ingredients of flour, cocoa, baking soda, baking powder, and salt in a bowl.
Then with a mixer, cream some room temperature butter and sugar until nice and fluffy. Then, add 3 eggs, one at a time, and beat after each addition.
Measure 1 cup of sour cream. (as if you don’t know what a cup of sour cream looks like)
With the mixer on low, add half of the flour mixture to the butter mixture. When that’s mixed in (be careful not to OVER mix, you want it to just barely be homogeneous). Follow that with half of the sour cream. Then repeat with the second half of the flour and second half of sour cream. By now it is super dark and chocolaty and gooey — there are all kinds of food hazards involved, but I couldn’t resist licking the beater on its way to the sink.
Now in the cupcake tins, rather than using cups, you’ll see why in a sec, brush them with butter and then dust with some cocoa powder. Time now to pour the chocolate gooey batter into the pans.
Stick the pans in your preheated 350 degree oven for about 25 minutes (obviously much less if you’re not using the jumbo cupcake pan). When they’re done, allow them to cool about 5 minutes and then run a knife around the edge of each and remove from the pans. They’ll have to cool completely before you touch them again — trust me, I tried to hurry a couple and it ruined them.
So while those are cooling, you can put together the marshmallow filling. It’s easy with just two ingredients: marshmallow cream and butter. Yes, more butter. Whisk those together and then stick it in the refrigerator for about a half hour just to firm it up a bit.
Now comes the really fun part. Maybe you’ve noticed a little problem in my blogging pattern — if not, I’ll take the liberty of pointing it out now. I’ve noticed that whenever the preparation gets a little dicey I start to concentrate harder and forget to take pictures. I’ll have to work on that, because this step is when pictures would really help. For now, use your mind’s eye
When the cupcakes are completely cool, take one and turn it upside down. Using a small spoon (or melon baller if you have one) carefully scoop a little circle out of the bottom. Save it and guard it with your life because you’ll need to put it back into the cupcake. Then scoop a little extra out and eat it (or discard, but that’s no fun) because you need space in there for the filling. Now, with the marshmallow filling in a pastry bag (or as close as you can get), fill in the middle of the cupcake. Be careful not to overfill it because the only thing holding it in will be that little circle you scooped out of the bottom (see why I said to guard it?). So, replace the bottom of the cupcake and then turn it right side up to dry. That sounds complicated and precarious, but it is a little (you thought I was going to say how easy and carefree it is, didn’t you?) So, that whole process is why I hesitated to make smaller cupcakes. What’s your thought?
Finally, with a little more of the marshmallow filling, pipe a little swirl ( or whatever you want) on top for decoration.
The math nerd in me figured that there is 1/4 of a stick of butter in each cupcake — EACH cupcake — so be sure you have somewhere to take them to share. Pretty and just a little out of the ordinary.
Here’s the list:
- 1 cup (2 sticks) butter, room temperature, plus some for tins
- 3/4 cup unsweetened cocoa, plus some for tins
- 2 cups flour
- 1/2 teaspoon baking soda
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 2 cups sugar
- 3 large eggs
- 1 cup sour cream
Filling:
- 1 1/2 cups marshmallow cream (the stuff in the jar)
- 1/2 cup (1 stick) butter, room temperature and cut into pieces
