This 5 minute flat diabetic sponge cake is just that, super spongy and delicious – and best of all, made in 5 minutes flat, seriously!

A few weeks back we showcased our 5 minute chocolate cake. This time it’s vanilla. And next time, well, who’s knows what deliciousness is on the menu – you better join our email list. 🙂

Traditional sponge cake comes in at a whopping 36 grams per piece. Now that’s going to send anyone’s blood sugar soaring and if you’re diabetic, that’s clearly a problematic food.

Our spongy cake is just 13 grams total carbs and 7 grams net carbs. Okay, truth be told, it’s not going to be exactly like that light, fluffy, super sugary sponge cake you’re used to—the one that’s super unhealthy.

But here’s the thing, you will still thoroughly enjoy it!

The topping is made from plain Greek yogurt so it has a kind of bitter sweet flavor that keeps you coming back for more. And of course, if you love lots of topping, make a double batch and eat your heart out.

In saying that, if you don’t like bitter sweet, swap the yogurt out for cream instead.

The recipe does use vanilla protein powder, and we covered how to choose a good protein powder here.

SWEETENER ALTERNATIVES

If you don't like stevia, you can swap it for tagatose, erythritol or monk fruit.

If you don't like bitter sweet—as in the yogurt for topping—swap the yogurt out for cream instead. You'll get a much more even, palatable flavor.
