Two of the professors in my department just emailed me saying they have a KitchenAid stand mixer they never use and would I be able to give it a home and make it feel used?
Just take a minute to absorb that.
Within 48 hours, it was in my kitchen making cupcakes for them.
I’ve made yellow cake once before, and as I remember it was good, but it took an awful lot of egg yolks. Instead of going back to that recipe, I just foodgawked yellow cake and found four recipes that looked good and came from reputable sources. I ran these through my baker’s percentage program to make them easier to compare and then picked Smitten Kitchen’s, because it looked like an especially moist recipe, and not one that contained egg whites. (Who puts egg whites in a yellow cake? The Culinary Institute of America, apparently. Shrug.)
I won’t copy the recipe here, but I will tell you that I used lowfat milk instead of buttermilk because that way I didn’t have to go shopping, and since I wasn’t going to have the acid of the buttermilk in the recipe to react with the baking soda, I replaced the baking soda with baking powder (the internets say amount of baking powder = amount of baking soda divided by three). Baking powder contains both baking soda and an acid for it to react with – gotta remember to balance your acids and bases, or your cake won’t rise and will have a metallic taste. Then I halved the recipe. It made 48 mini cupcakes, exactly two pans’ worth. I seem to have underfilled the cups, because most of them didn’t rise enough to make little tops for themselves, so maybe it should actually make less than that.
You’re supposed to bake the cake for 35-45 minutes, but the mini cupcakes baked in about 18 minutes at the same temperature, 350F.
The review: Wow. First of all, making a cake with a scale and a stand mixer is a lovely experience. Everything was so easy and fast. Secondly, this is a great cake recipe. Soft (cake flour is a good thing), moist, fluffy. The tops are flat; I have no opinion on the optimal shape of the top of a cupcake, but now you know what you’ll get out of this recipe. They’re losing moisture fast, though, so if you make them, eat them forthwith.
Chocolate Swiss Meringue Buttercream
Buttercream frosting and I have a shady past. I tried to make it three times in a row to no avail. First, a whole egg buttercream that fell flat. Then, an egg yolk buttercream that was unacceptably salty because I used salted butter (normally you can get away with salted butter; not in buttercream!) and that really had too much butter in it, anyway (it got so hard in the fridge that I was able to pick up the entire mass by one edge and throw it away). Finally, another whole egg buttercream that just never came together, no matter how long I beat it with my hand mixer. It seemed to me that buttercream frosting was one of the few things that I couldn’t figure out how to make without a stand mixer. So it was the perfect recipe to welcome my new toy to my kitchen. But this time, I decided to make an egg white buttercream, because I imagined the meringue would be better at balancing out all that butter than the egg yolks had been.
I used a recipe from My Buttery Fingers which is based on a vanilla buttercream from Smitten Kitchen (whence all good things come, apparently!) and a chocolate espresso buttercream from Use Real Butter. The only changes I made were to beat the egg whites to fairly stiff peaks before adding the butter, rather than adding it as soon as the meringue was cool, and to use 150g of butter rather than 180g, which Wendy suggested. I think it was absolutely the right choice.
The recipe worked perfectly. It’s normal for buttercream to separate into a chunky solid phase and a liquid phase before coming together again, but mine never even did that. It was just perfect the whole entire time. My hand mixer couldn’t quite get Swiss meringue to stiff peaks; I tried once for long enough that I ended up moving the bowl and mixer to a table so I could sit down, and all I got was an overheated mixer and soft peaks. So expect to see some piped meringues in the future.
As for the flavor of the frosting, I think it was a nice amount of chocolate. You could go chocolatier, but only if you want to really make a statement. This was a nice, classic yellow cake-chocolate frosting combo.
