In the name of journalism, Scooter and I made mug-cakes the other night at 2am. Rating: yes.
We used the recipe I posted previously, although we substituted melted salted butter for the oil, a recipe mod I endorse because (a), salted butter is a much more useful thing to buy than weird baking oil, and (b) the slight saltiness adds complexity to the flavour of the 5-minute microwaved mug cake. And snacks you make at 2am can always use more complexity, eh? Sometimes I take all the vowels out of the Alpha-Getti just for a challenge.
Another recipe mod I would endorse is using a wee bit more cocoa and a wee bit less flour- maybe altering the original recipe’s ratio by a tablespoon in each direction. That would make the cake denser and more chocolatety, both of which are good words in the dessert arena. A not-as-good word in the dessert arena is “obesity”, which can be “caused” by “late-night” “gluttony”.
Also: use a large mug.
Mixing batter in a mug is challenging, so use a fork (even though the sound of the fork-tines scraping the mug upsets some very primal part of my brain). And stir the dry ingredients well before adding the egg & butter, or else you end up with a layer of dry, unmixed flour at the bottom of your mug cake, like one of us did, and then the other of us (the one whose mom is a professional pastry chef) laughed at me and I hid in the bathroom.
I don’t know from baking but I did pick up some cake & pastry flour for the mug cake, and my cake rose pretty well. I suspect that using all-purpose flour might have a detrimental effect- the mug is so small that it’s hard to get bubbles into the batter by stirring- whereas cake flour is more encouraging, promoting better self-esteem in batter applications.
It will look like the mug can’t possibly hold all that mug-cake, but it probably will. Mine only overflowed by a couple drips, even though the uncooked batter reached right to the top. Yay uncritical optimism, I bet this means everything else will work out fine, too!
Also: don’t forget to buy some milk to wash down your epicurean genius.
And there we have it, folks: Mug-cake. Dee-licious.
