Can gluten-free cakes actually be fluffy? The answer is a big YES. All you need is rice flour. Those who are gluten intolerant, or choose the gluten-free way of life (no-judging..) can too experience fluffy sponge cakes. I’ve always loved my signature soft and fluffy sponge cakes, and am stoked to have cracked the code to a gluten-free version. This recipe is Coeliac certified!
The most rewarding part of baking is certainly not the cleanup. It’s being able to share and bring joy to others! This has become one of my top baking moments. My coeliac friend let out a surprised “HOLY smokes” after the first mouthful of this cake. Surreptitiously slicing bit by bit while we were chatting, it wasn’t long before half of the cake was demolished!

The science:
The best part is, you don’t even need to invest in a bag of gluten-free flour, only rice flour is needed. Rice flour is naturally gluten-free and packets like the above can be found easily in Asian grocery stores. I would recommend buying it from the Asian stores because they tend to be ground to a finer consistency. Essentially, rice flour is made from ground rice grains, which do not contain gluten. Gluten is a type of protein found in grains such as wheat, barley, and rye. When these grains are milled into flour, the gluten is retained, which gives the flour its elasticity and chewiness.
As rice flour doesn’t contain any gluten, this makes it a popular alternative to wheat flour. I use it in my snowskin bunny mooncakes. It is also used to make chewy rice noodles, dumplings or even breading for pan frying.
So let’s not keep yourself or your gluten-free friends waiting. Give this sponge cake recipe a go! Make sure you tag your creations with @ultimateomnoms on Instagram, I’d love to see it and give you a shoutout.
