What is Keto Mug Cake?

A keto mug cake is a low-carb, high-fat dessert that’s super popular among people on a keto diet as it’s cooked in the microwave in just 90 seconds. It’s a delicious way to satisfy a sweet tooth while keeping the carbs minimal.

The common ingredients for a keto mug cake include almond flour, coconut flour, eggs, baking powder, butter, and a low-carb sweetener like erythritol or monk fruit.

The low carb mug cake is cooked in a mug for just 2 minutes and can be made with various flavors like vanilla, chocolate, or lemon.

Are Blueberries Keto-Friendly?

Berries have the lowest sugar content of any fruit, including blueberries, strawberries, and raspberries.

Blueberries are perfect for a ketogenic diet if consumed in moderation. So you can incorporate them into your daily macros.

1/2 cup of fresh blueberries contains about 9 grams of net carbs, which is a significant amount of the daily carb limit for someone following a strict ketogenic diet.

They are also low in calories and have a relatively low glycemic index, which means they won’t spike blood sugar levels as much as some other fruits.

If you want to include blueberries in your keto meal plan, it’s best to eat them in small quantities and balance them out with other low-carb foods.

One way to incorporate blueberries into a ketogenic diet is to use them as an ingredient in keto-friendly desserts, such as low-carb muffins, cakes, or cheesecakes.

This can help manage portion sizes and overall carb intake while still enjoying the flavor and health benefits of blueberries. However, it’s important to note that even in desserts, blueberries should be consumed in moderation to avoid exceeding your daily carb limit.

Ingredients You’ll Need

You’ll need just a few easy-to-find ingredients to make this delicious mug cake. Here is a note on the ingredients.

• Coconut Flour and Almond flour – I’m a huge fan of using both flours to get that perfect texture that resembles a regular fluffy muffin.
• Blueberries – I used fresh blueberries; you can also use frozen ones; make sure to coat them in coconut flour so the cake doesn’t become mushy due to the extra moisture.
• Sweetener – I used granulated Erythritol, but you can also use Monk Fruit Sweetener or Allulose.
• Eggs – use large eggs at room temperature; otherwise, the mug cake may have an eggy taste.
• Baking Powder – helps the cake rise.
• Lemon –  I used lemon extract and lemon juice to get the best lemon flavor. Feel free to replace it with vanilla extract.

How To Make Keto Blueberry Mug Cake

Another great thing about this recipe is that it is extremely easy to make using just a tall mug. Here is everything you have to do:

Mix all the ingredients into a microwave-safe mug that’s large enough.

Once the batter looks smooth, fold in the blueberries.

Microwave and cook for 90 seconds. If the center is still moist to touch, keep cooking at 10-second intervals until ready.

Remove the mug from the microwave and let it cool for a few minutes.
