Moist low carb lemon cupcakes are slathered with a lemon cream cheese frosting are bursting with the flavour of lemon making them perfect cupcakes for Spring.
These keto cupcakes are baked with coconut flour and are so easy to make. The frosting is a tasty blend of cream cheese, butter and flavoured with lemon juice. Double the lemon flavour for this lemon cupcake recipe.

This lemon cupcake recipe received a big thumbs up from the Chief Taster and are now on the repeat list. As these cupcakes are quick and easy to make it’s a request that can happily be met. Unless we are out of lemons and I have no lemon extract. Lemon extract will work but it’s not the same taste as fresh lemons.
Can I Make These With Almond Flour?
If you want to use almond flour in place of coconut flour, then increase the quantity to 2 cups almond flour. Add the optional water to make sure the mixture is smooth and not too thick. The cupcakes should still be as light and fluffy as the coconut flour ones. Both flours bake a great lemon cupcake.
