If sometime during this pandemic you've decided that you were cooped up/bored enough to embark upon a true baking adventure, that you would finally tackle Hong Kong egg tarts and 90 minutes later, every visible surface of the kitchen is encrusted in flour, every appliance and cooking utensil you own has somehow been utilized/dirtied, and all your former culinary aspirations have been exposed as a wastrel's pipe dream - you realize that you have actually come to despise flour, and oil, and sugar, but most of all, you loathe the starry-eyed fool you were 90 minutes earlier, the one who, despite never having exhibited any particular talent for pastry or custard, decided it would be nbd to recreate a dim sum staple that perfectly highlights the culinary resourcefulness and imagination your forebears demonstrated while living under the yoke of British colonialism and ethnocentrism - now, 90 minutes into a deep and unmitigated mess, you have nothing to show for your troubles but chaos, and all you really desire anymore is a hard cold exit from your kitchen to an utterly new life/beginning, Jason Bourne style... if any of this nightmare feels at all familiar, Yossy Arefi's Snacking Cakes may be exactly what you seek.
Arefi's recipes call for dirtying 1-2 bowls at most (especially if you weigh your ingredients instead of using measuring cups), oil or melted butter (not room temp, so no pre-planning to set out butter hours beforehand), and mixing with a whisk, with no other fancy gadgets, aside from a grater here or there; I've only found one recipe that asks for a hand mixer and softened butter (she profusely apologizes for this in that recipe's intro). Every recipe has different pan size options listed (square, round, Bundt, etc.)
However, there's more to this book than just baking ease; because Arefi has a highly diverse (yet approachable) palate, the adventure is not in techniques, but rather, in the flavor combinations. I've made an orange/beet/poppyseed chocolate cake with beet and orange glaze (thumbs up), and a rhubarb cake with a sumac crumb topping (which my evil children ate the very last pieces of while my back was turned, a bittersweet triumph). She has interesting variations for every recipe, such as switching out some of the AP flour with rye or buckwheat, and listing a few possible glazes for each recipe that would greatly alter the final effect, thereby expanding each recipe to represent 2 or 3 more. One of my kids has severe nut allergies - this book offers enough variations to work around that, except for maybe one or two recipes. [However, if you're gluten-free or vegan, I would check it out from the library or at the bookstore first; there's less flexibility with those diets.] If you're like me in not really caring about improving technique, but still enough of a food snob that you can't accept the glut of online recipes that are essentially rolling a stick of buttered cream cheese in powdered sugar sprinkles and calling that a result, this book hits exactly right.
3 more things: 1) I would exercise caution with the printed bake times - I've had to shave off an average of 10 minutes for all 5 recipes I've tried so far (most of us know not to follow recipe bake times to the letter in general, right? My point is, they are even more off than I'm used to - mayhap her oven and mine are entirely different species); 2) because of the melted butter thing, the only vanilla-based cake I've made so far was kind of corn-bready; overall, some of the more delicate cakes might come off tasting like "easy" cakes, though for me, Arefi's ingenious flavor profiles compensate for those compromises; 3) Arefi explains early on that a snacking cake is a cake you have on the counter that you cut off a slice of every time you walk by, which I can 100% vouch for. If you are at peace with this scenario, and the devil's knowledge that would bring this vision to fruition, this book is the source.
