Hi Gemma,
Just want to say that I am thoroughly impressed by your expertise and videos – they’re so very enjoyable to watch, simple straight to the point and entertaining as well! Thanks for all the work you do to bring us these amazing recipes! Also appreciate the fact that you take the time to reply to everyones comments. That’s dedication!
Hi Gemma, I’m wondering is there any substitute for white egg? Or can I just leave it out?
Thanks,
Ika
I tried this out, and it was good except that it was not sweet at all! I thought I left sugar out, but it was right; there was no sugar. I even used a VERY ripe banana, but to finish the job, I sprinkled on chocolate chips. It made it sweeter and added a chocolate kick.
Hi Gemma tried this cake for my husband and he loved it clearly earned some brownie points with him ???? I drizzled some honey on the cake before I served and he loved it thank you !! Gini
Delicious! I did with a scoop of vanilla protein powder, and just 2 T of oat flour. So filling!
Love it!!! Made this using peanut butter powder to cut fat… and some dried cranberries! Delish!!!
Did work well. Just not my kind of cake. Tasted mostly like Banana 😉 loved the sponge cake, so I will go back to my all time favourite 😀
Hi Gemma. Love this mug cake and I often make it for breakfast to kickstart my day. I add a little drizzle of honey on top while it’s warm, too. Just wondering why you use only the egg white though and not the whole egg. What’s the reason, please?
Ohhh my. My children loved it. I made two, bc I wanted to use the whole banana up. ???? I added about a tsp of honey and some walnuts. Went so fast that I forgot to take a photo. Lol
Could coconut flour be used
