The recipe shown is for 1 large coffee cup size mug cake. If you prefer, you may divide the low carb mug cake mixture between 2 smaller cups but ensure you reduce the cooking time from 1 minute to 40-50 seconds. Cooking time will depend on YOUR microwave.
3 ways to cook
These low carb mug cakes are cooked in the microwave, and so because all of our microwaves are completely different, it may take a little experimentation to get the cooking time just right (so please don’t come running back to me if yours was over/undercooked, I won’t reply because I’ll be busy eating mine 😉 ).
If you know your microwave is powerful, reduce the cooking time by a little and test the center. You can always add another 10 seconds or so but there is nothing worse than an overcooked, dry, and rubbery mug cake.
Do I need a microwave?
No, you can also cook mug cakes in the oven or in your air fryer. If you use the oven, you will have to choose a heat-proof small baking dish, large muffin tray, or ramekin.
Make the mug cake batter as shown in the recipe card then bake at 180C/250F for 15 minutes. Or until the center is cooked.
3: Air fryer
To cook mug cakes in the air fryer you need to find a small baking dish or ramekin to fit inside your air fryer. There must be at least 1 inch on all sides to allow the heat to circulate evenly.
- Preheat your air fryer to 180C/350F.
- Place the butter in your small baking dish and heat for 30 seconds to 1 minute, or until completely melted.
- Make the mug cake following the recipe card below.
- Gently lower your baking dish onto the air fryer wire rack. Ensure there is plenty of space between the ramekin dish and the side of the basket.
- Cook for 10 minutes, depending on the size of your air fryer and the size of your ramekin or small baking dish.
Serve your cooked chocolate mug cake with full-fat cream and low sugar berries for a real treat.
For adults only, you might like to pour a little brandy over them or add brandy to the whipped cream for a grown-up indulgence.
