Troubleshooting Your Keto Mug Cake

Easy as it may seem to whip up a keto mug cake, some common troubleshooting issues can arise. Here are a few tips to ensure your mug cake turns out perfectly every time:

1. Different Microwaves Have Different Settings

If your mug cake is not turning out how you expected, try adjusting your microwave’s power level and/or cooking time. 

What happens is even though the recipe dictates a certain cooking time or power level, the wattage of your microwave can vary. This can cause inconsistent results with your keto mug cake recipe. 

Some signs that your cooking time and/or power level need to be adjusted can include the cake not rising, cracking around the edges, or an undercooked center.

2. Choosing The Right Mug Size

Using a mug that is too large will also cause your cake not to rise properly and can also cause an undercooked center. On the other hand, using a mug that is too small will cause your cake to overflow and can make it difficult to remove from the mug once cooked. 

The general rule of thumb is to use a mug with a volume capacity of at least 200ml. Go for one that’s wide instead of tall and make sure to grease the mug before adding your batter. Ensure that your batter doesn’t go higher than ½ of the mug.

3. Use Room Temperature Ingredients

It’s important to use room-temperature ingredients when making your keto mug cake. This ensures that all of the ingredients mix smoothly, evenly, and without any lumps. 

If you use cold ingredients, your batter can be lumpy and won’t mix properly. This will cause your mug cake to not cook evenly, resulting in an unevenly cooked exterior and an undercooked center. 

4. Baking Powder

The purpose of baking powder is to make your keto mug cake rise and cook evenly. If you do not use the correct amount of baking powder, your mug cake may not rise or may not cook evenly, resulting in an unevenly cooked exterior and an undercooked center. 

Baking powder that has gone bad can also cause your cake not to rise. It’s always a good idea to check the expiration date on your baking powder before using it to ensure it’s still good

5. Keeping It Keto-Friendly

It’s essential to make sure all of the ingredients used are keto-approved. Some commonly used non-keto ingredients when making mug cakes are regular flour, sugar, and milk. These ingredients can add excess carbs to your mug cake which might kick you out of ketosis. 

Make sure to double-check that the ingredients used are keto-friendly before adding them in! 

The Bottom Line

A keto mug cake can make dessert time a lot easier and delicious. By following the tips above, you can guarantee your mug cake will turn out perfectly every time!
