This recipe is an amalgamation of two already on the site: my Hot Chocolate Mug Cake and the Lemon Muffins. It combines the zesty brightness of the muffins with the convenience of a mug cake! It's really filling, too!

How to Make a Low Carb Lemon Mug Cake

In a jug, melt some butter in a microwave. And yes I prefer to mix it in a jug first THEN cook it in a mug, but feel free to prepare it all in the mug!

Add some lemon juice (fresh is best but bottled will be OK) A handheld lemon squeezer is great for this task!

Whisk in an egg, then add almond flour, sweetener (I like using golden Lakanto but any granular sweetener would work), baking powder, lemon zest (I use this Microplane zester!), and lemon extract. The extract is optional, but definitely adds a little lemony punch to the cake!

Transfer the mixture to a small mug or cup.

Microwave the cake batter for 1 – 1½ minutes in the mug, or until the center is cooked. And that's it! SO easy! You could also serve it with a swirl of whipped cream and a slice of lemon as shown here – but the cake is so soft, warm, and delicious, it doesn't really need it!

I'm interested why you are concerned about the calories. Most people on low carb and keto diets don't count them. Let me know which diet you are following!

What can I use to substitute the simple syrup?

Do you have a liquid sweetener that you like? Depending on the style you may have to experiment with the quantities to get the right sweetness.
