Lemon Blueberry Mug Cake

Keto Lemon Blueberry Mug Cake


My lemon blueberry cake is bursting with beautiful natural flavors and so refreshing! This moist, easy to make cake is filled with delicious blueberry and lemon zest.


Mug cake is so fun and delicious. Very nice for portion control and having a treat when others are eating sugar.


This cake is beyond moist, with the perfect zing from lemon zest and juice.

I’m not sure if my meager description is doing the cake any justice but it was soooo good!


I really loved it as a naked cake because the cake itself is so tasty it really doesn’t need a glaze, but it looks pretty and it gives an added “zing”


Blueberries: I love fresh blueberries with this recipe but you can use frozen ones. Thaw before use then drain. Wild blueberries are my favorite, but regular are great as well.


Lemon zest. Lemon zest makes all the difference. Make sure you zest your lemons before you juice them! It will be quite a challenge to zest a juiced lemon.
