There’s something about lemon cake that makes it feel a little less ‘naughty’ than other cakes. Which is just as well, as these low-carb cupcakes are a crowd pleaser that you’ll find it hard to stop at one! The outside is slightly crisp, with a light, moist filling.

These cupcakes feel a little rustic to me, so I like to serve them with a blob of sugar-free frosting rather than piping it on, but if you’d prefer something a bit fancier you might want to double the frosting ingredient amounts to give you enough to work with.

Recipe Tips

Note that these muffins are more on the dense side. If you prefer fluffier muffins, add 1-2 tsp of baking powder and 2-3 large eggs. Keep in mind that this will also result in more muffins or bigger muffins.

I make these often, adding an extra egg and baking powder to make them lighter and fluffier.  However, I have never managed to get a spreadable/pipeable frosting using the ingredients indicated.  I always have to add whipped double cream to give it enough body to hold its shape or spoon onto the muffin. Without the whipped cream the ingredients are just too liquid.  Any suggestions?

Thank you so much for your feedback, that is a great suggestion! I myself have had very different results with different types of cream cheese. Some were indeed too runny. I have tested the frosting on another recipe so I'll amend it to make sure there are no more runny frostings!
(I'm sorry for the delayed response, life gets busy with newborn twins!)

Good to hear, thank you,  And congratulations and good luck with your little babes!

Thank you!

Hi, I was wondering if it would be okay to use the caviar from a vanilla pod? I can’t find sugar free pure vanilla anywhere.

Absolutely - that is my preferred option too! I get whole vanilla pods or vanilla bean powder from Amazon.

Hi - I made these today and they are really delicious!  However, We found them quite dense and I wondered if there is some way I could make them lighter or more fluffy.  They didn’t rise at all and I wondered if more baking powder might help?  Any thoughts/comment?  Thank you.

Hi Christiana, I'm glad you liked the flavour! There are 2 ways to help them rise more. Add 1-2 tsp of baking powder and 2-3 eggs. This way you will end up with a fluffier sponge/muffin 😊 It will also yield more muffins or bigger muffins. I hope this helps!

Thank you for the advice - will certainly give that a try - soon!

More baking powder and an extra egg did the trick, thank you!  And now other question - do you think these would freeze well - question in light of the comment to serve immediately or keep in the fridge for 5 days?  Thank you so much for all the wonderful recipes and advice, much appreciated.

Oh I'm happy it worked well! Yes you can definitely freeze these but without the frosting. That is always best prepared fresh (the frosting will keep for 5-7 days in the fridge, in a sealed jar). So if you need to freeze the muffins, you may have to halve the amount of the frosting and only use it for the batch you will keep in the fridge.

Brilliant!  Thank you!
