💡 Fun Ways to Serve a Keto Mug Cake
- Piped Whipped Ganache – Cool the mug cake slightly, then top with a swirl of whipped chocolate ganache. Pure heaven.
- Sundae Style – Add sugar-free ice cream, ganache or chocolate sauce, and crushed nuts for a mug cake sundae.
- Berry Shortcake – Top with whipped cream and a spoonful of keto berry jam or fresh berries.
- Mini Trifle – Layer chunks of mug cake with whipped ganache, berries, and a sprinkle of crushed nuts in a ramekin.
- Tropical Twist – Add coconut cream, lime zest, and toasted coconut flakes for a fresh, zesty finish.
Tip: Let your mug cake cool before topping to keep whipped ganache from melting too fast!

Wow!! This recipe is stellar. I’ve shied ร way from mug cakes for so long because I’m often disappointed. But this was so fabulous.
First I cut up 3-4 strawberries and added them to the batter before microwaving. When the cake was done I topped it with a bit of cream and it was a delight!

I would like to try this recipe but I don’t have any collagen.
I only have different flavors of True Whey protein powders and a natural Soy Protein isolate.
Is there any substitute for it?
Thank you.-
It might turn out a little heavier Hana, but worth a try. Some protein powders have different additives so it is hard to say.

I often find other mug cakes dry โฆbut I cooked this one a little less in microwave
and swapped collagen with WPI (salted caramel)
Added 1 t natvia salted caramel sauce to mixture
and served with salted caramel sauce and cream ๐คค-
So good to hear you sorted it out. Just an FYI that WPI is much drier in baking too than collagen x

So quick and easy!! I tipped some frozen mixed berries in to the bottom of two microwave cups and split the mixture to make two very decent size mug cakes and topped with cream! I added lime zest and half the juice of a lime with almond meal as a sub for collagen. I was worried about the coconut flour, but could not tell! Delicious and moist!-
I love this cake mixture. It is so versatile and you are absolutely right regarding the coconut flour flavour.
