Happy National Donut Day! Does this mean we can eat all the donuts we want and calories don’t count today? If so, you should make three of these cakes. Actually, I didn’t even know Donut Day was a thing until I saw donuts popping up all over Instagram yesterday. I made this cake a couple of months ago for a silent auction, but hadn’t gotten around to posting it out of sheer laziness, so the stars aligned and it’s coming to you on National Donut Day!
The cake itself is a super simple chocolate cake recipe that I got from here. I doubled the recipe to get a 3 layer 6-inch cake plus about 16 mini donuts (or really, donut shaped cakes). Although this cake recipe is vegan, I used cow’s milk since the frosting is not vegan. Speaking of frosting, coffee swiss meringue buttercream is quite possibly the most heavenly creation on earth. I used 2 shots of espresso from my favorite local coffee shop in the frosting, but you could also use 2 tablespoons of instant espresso powder dissolved in 2 tablespoons of water, or 2 tablespoons of coffee extract (I like Nielsen Massey brand).
The frosting recipe makes a lot, so before you tell me that this recipe makes too much frosting, here’s why (also, please stop complaining about an overabundance of frosting). I wanted to crumb coat the cake and have enough frosting to get a really smooth finish since I knew that people would be bidding on this cake. The leftovers freeze really well (or taste good spooned directly into your mouth). Plus, it’s always nice to have some extra Swiss Buttercream in your freezer.
If you’ve read any of my previous posts, you know that I use pasteurized liquid egg whites 99 percent of the time when I make SMB. I’ve tried it with both fresh and liquid egg whites, and while the liquid egg whites whip up slightly fluffier, I don’t find that it makes a difference in the finished product. Plus, you don’t need to heat liquid egg whites past 120 degrees, which makes the whole process go faster. So unless I know I have to make a very large batch of pudding in the near future, liquid egg whites it is. And don’t forget to wipe down all your tools with vinegar before you start. Any traces of grease will prevent your meringue from whipping up properly.
As for the butter, the ideal temperature should but soft, but it should still retain it’s shape. If the butter starts to get greasy or mushy, you may have a harder time getting your SMB to come together. In case your butter is too soft (or your egg whites are too warm), just stick the whole bowl of frosting in the refrigerator and try beating it again.
For the cake, double the recipe here. This makes a 3 layer 6-inch cake plus about 16-20 mini donuts. You’ll need a mini donut pan like this one. Make the glaze in the recipe below. Dip one side of the donuts into the glaze, and then cover with sprinkles. Let the glaze dry while you frost the cake.
