Who wants to be stood cooking all day after a long day at work? I know despite my love for cooking and baking I don’t and this Keto Microwavable Lemon Mug Cake is perfect when you want something sweet quickly.
I love easy sweet treats and this Lemon Mug Cake with lemon glazing is super quick to make in the microwave. You can skip the glazing but I do recommend you give it a try.
You can get mug cakes in different flavors I have tried Keto Chocolate Mug Cake and Keto Peanut Butter Mug Cake and both are a delight.
What better keto dessert that is made in 2 minutes in a microwave.
