Do I need a microwave to cook mug cakes?

I understand that many of you don’t own a microwave or don’t like using them.

You can still make the keto vanilla berry cake batter, but you will have to cook it in the oven.

Of course, it is no longer a 1-minute mug cake, and it becomes a 12-minute cupcake instead. But it can be done.

Simplybake at 180C/350F in a cupcake case or muffin tray.

Air fryer

To cook mug cakes in theair fryeryou 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.

  1. Preheat your air fryer to 180C/350F.
  2. Place the butter in your small baking dish and heat for 30 seconds to 1 minute, or until completely melted.
  3. Make the mug cake following the recipe card below.
  4. 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.
  5. Cook for 10 minutes, depending on the size of your air fryer and the size of your ramekin or small baking dish.

Why does the mug cake use coconut flour?

If you have been with me for a while then you know I love coconut flour. And if you are new here, remember to subscribe here and get a free copy of my Top 10 Low-Carb Recipes to get you started.

Coconut flour is a wonderful low-carb, keto, gluten-free flour. It is light, packed with fibre, easy to use, requires very little quantities and so ends up being a very affordable baking grain-free flour.

Can I use almond flour instead of coconut flour?

It is not easy to swap coconut flour for almond flour because they have completely different properties when baking.

I do have this chocolate mug cake recipe that uses almond flour. It is absolutely delicious.

Can I eat sugar-free dessert recipes all the time?

In the long term, we want to rely on sweet recipes less and less. And we want to use sweeteners, less and less. So why do we need sugar-free dessert recipes?

Because if I told you that you were never alloweda sweet treat ever again, most of you wouldn’t even contemplate embarking on a keto or low-carb life!

Another reason for havingamazing sugar-free recipes is so you may offer to bring a healthy sugar-free and low-carb dessert to a party or dinner party.

Because if you bring a keto or low-carb dessert, you are in control of the biggest source of sugar and carbs in a meal.
