Lemon Curd Keto Mug Cake

Lemon curd is definitely one of my favorite sweet treats. The tangy taste and the creamy texture always make me want to eat it by the spoon (shame on me right???).

Sometimes we are so tired or lazy that imagining having to go to the kitchen and spend 45 minutes or more baking a treat is disencouraging.

With that in mind, and although mug cakes are not on the top of my list, I created this recipe.
Its is moist, tangy and sweet, and does perfectly the trick.

So, what are you waiting for? Make it and let me know in the comments how it went.

For the Lemon curd

  • In a small sauce pan melt the butter on low heat
  • Remove from the heat and add the sweetener, lemon juice, and lemon zest whisking until the sweetener dissolves.
  • Whisk the egg yolks and add them to the butter mix, and whisk well.

In a bowl add all the ingredients.  Mix it well, and microwave on high, for 55 seconds (depending on the microwave it might need more time). Add extra lemon curd, and the blueberries on top and dig in!

    This looks wonderful. I love lemon curd on cheesecake when we have company but never know what to do with the rest of the curd other than eat with a spoon…. thanks so much for this!

    Lemon curd – so zingy and zesty and it looks beautiful. I’ll make this after I have eaten my 3 remaining lime and yuzu panna cottas.
