Blueberry Muffin Keto Mug Cake

Jump to recipe

In general, mug cakes are one of the easiest and most convenient desserts to have regardless of which diet you follow.  They only require a handful of ingredients and can be made in under 5 minutes. They hit the spot at the end of day and never seem to disappoint you when your sweet tooth has spoken up.  Chocolate always hits the spot when it comes to dessert, but every now and then it’s worth changing up the routine with flavors.

The Main Ingredients in This Mug Cake Include:

Blueberries and fruit aren’t standard on a ketogenic diet, but should also not be feared.  While most fruits are not low enough in net carbs to keep you in ketosis, wild blueberries are a wonderful option to have on hand and could be enjoyed in moderation.  Not only that blueberries provide wonderful nutritional benefits.

Benefits of Blueberries:

  1. High in antioxidants
  2. Reduce inflammation
  3. Supports digestion

#1: Top Antioxidant Food

Blueberries are synonymous with their ability to fight free radicals, prevent cell damage, and protect against a variety of diseases.  Many studies and research show promising results for antioxidant rich foods like blueberries to inhibit the growth and spread of many types of cancer.  Antioxidants can also help protect the brain, enhance memory, and improve focus.

#2: Anti-inflammatory

Due to its antioxidant content, blueberries are also known to have a positive impact on inflammation in the body.  Polyphenols found with blueberries can help reduce the activity of several inflammatory markers.

#3: Rich in Fiber

One of the reasons why blueberries are a great option on a ketogenic diet is because it contains more fiber than most other fruits.  Fiber will help promote regularity and the digestive process. It can also help bulk up stool and alleviate conditions like IBS and constipation.

As long as you track your carbs and don’t get too carried away with berries, there is absolutely no reason they can’t or shouldn’t be enjoyed on your ketogenic diet.  Fortunately the amount used in this recipe is so minimal you can get a fruit fix and stay in a fat burning state of ketosis.  Another benefit to using frozen wild blueberries is they are picked and frozen at the peak of the season which means they are packed with flavor.  A little goes a long way with these berries.
