It’s kind of crazy to think about how much baking has changed since I first started dabbling in it around 18 years ago. And holy snap did I ever just age myself. But I digress.
The point is, baking is a lot different today than it was when I was learning the ropes as a kid. Back in my day (har har), you followed a pretty basic formula involving flour, butter, sugar, and eggs; and while that’s obviously still around today, more and more people are turning to alternative ingredients like almond flour, coconut palm sugar, flax eggs,
fairy dust, etc. to get the job done.
Or maybe it just seems that way to me because of the healthy living blogger bubble I live in? The one where using coconut flour in things like this blueberry banana bread mug cake is pretty commonplace?
Either way! I’m pretty sure everyone’s seen at least a handful of recipes involving flour/butter/sugar/egg alternatives; and I know you’ve seen way more than that if you’re a regular Spoons reader since those things are kind of the [flourless] bread and [dairy-free] butter around these parts. See what I did just there? 😉 Smooth.
In all seriousness, though, I love using the alternatives in my recipes. Partially because they generally tend to be a little bit healthier than their classic counterparts, and partially because they’re just plain fun to experiment with (hashtag geek). Things like gluten-free, grain-free, paleo, and/or vegan baking weren’t really a thing when I was growing up, and being part of the influx of those kind of recipes in the last handful of years has been pretty neat.
At least when they turn out. Ask me again how I feel about grain-free vegan baking when I’ve got 5 failed flourless eggless muffin recipes under my belt and I might be singing a different tune. A colourful one that’d probably make sailors blush.
But the failures just make the successes that much sweeter, and when you strike gold, you strike freaking gold.
Take today’s light and fluffy blueberry banana bread mug cake, for example. Would you believe me if I told you that it’s made with NO flour, butter, or oil, but soooooo incredibly soft and fluffy that you’d never know unless someone actually told you?
Believe me; I’ve tested that theory on my
poor, unsuspecting taste-testers. And before you go feeling sorry for them, remember that the job comes with heaps of free food and not that many flops. They’re a happy, well-fed bunch. And this is a ridiculously doughy grain-free mug cake…
You know those alternative ingredients I was talking about? It’s recipes like this where they really shine.
One of the most common questions I get about my mug cakes is whether or not the coconut flour can be subbed out with regular flour, and the answer is no… at least not without making a lot of other adjustments. Coconut flour is really unique in how it absorbs liquids, and it’s what lets these mug cakes stay nice and moist without any additional oil. It also makes them super fluffy and cake-like, despite the fact that they’re grain-free.
I normally try to provide more common substitutions, but this is one of those occasions where I’m going to tell you that you need to go out and pick up a bag of coconut flour, if only to use it in mug cakes. It will change.your.LIFE.
