One of the recipes I made this weekend was a disaster, so I quickly had to think of something else. Using my birthday mug cake recipe as a base, I came up with this keto blueberry mug cake recipe.

It's a nice treat that's ready in minutes!

💛  Why you'll love it

Mug cakes and muffins are perfect for a quick snack or breakfast.

My youngest daughter loves blueberries, so I had some fresh berries in the refrigerator.

My favorite recipe for using the tons of blueberries we pick over the summer is a cobbler. I also like making a syrup to pour over pancakes and mix into plain yogurt.

Now, I have a quick and easy low-carb blueberry mug cake recipe that I can throw together. It will be a yummy treat in the morning on the weekends or a snack after work.

This tasty mug cake recipe could also be made in larger batches and baked in the ramekins. It should only take 10-15 minutes to bake in the oven.

Mug cakes are pretty convenient and are perfect for college kids living in the dorm. Much healthier than the microwave popcorn we used to snack on.

Although I could make up a mug cake in the microwave at work, I'd probably just make it at home first and heat it up in the toaster. The size of each blueberry mug cake is perfect for toasting.

This is the perfect recipe to satisfy your sweet tooth.

📋 Ingredients

There are only a few simple ingredients in this keto blueberry mug cake. If you have ever made a low-carb cake before, you probably already have all the ingredients that you need.

Flour

You will need both almond flour and coconut flour. In order to keep the carbs low, I do not recommend using Bob's Red Mill gluten-free all-purpose flour. It has too many carbs.

Blueberries

Use either fresh or frozen blueberries - they both work perfectly in this recipe. You only need a small handful.

Baking ingredients

You will also need basic baking ingredients such as salt, baking powder, vanilla extract, and lemon extract.

Wet ingredients

You will also use coconut oil as the fat, heavy cream for richness and flavor, and an egg to hold it all together.

Sweetener

Any granulated or liquid low-carb sugar substitute will work perfectly in this blueberry muffin mug cake.

💭 Tips

• Top with whipped cream. This enhances the blueberry mug cake after it cooks.
• Add blueberries on top. Save some fresh blueberries and add them on top of the cake after it bakes.
• Spread on some cream cheese frosting. If you want to make this taste like a real cake, make a keto cream cheese frosting and spread it on top.

🔪 Instructions

This blueberry keto mug cake is so easy to make that even kids can make it.

Mix the dry ingredients

In a small bowl, mix the almond flour, coconut flour, baking powder, and salt, and then add the blueberries.

Combine wet ingredients

In a small microwave-safe bowl, melt the coconut oil. Then, mix in the heavy cream, egg, sweetener, and extracts.

Mix everything together

Mix the dry ingredients into the liquid ones. Add the batter to a microwave-safe mug or two ramekins.

Cook the blueberry mug cake

Microwave on high from 1 ½ minute to 2 minutes or until cake is no longer wet. It took about 2 minutes to bake in my 900-watt microwave.

🍽️ Serving suggestions

This dessert cuisine tastes perfect for breakfast, brunch, or as a snack when you are feeling kind of hungry.

Serve this keto blueberry muffin with a scoop of low-carb ice cream as a delicious treat.

Top with lemon zest and serve it with a shortbread cookie if you are craving even more sweets.

Serve this delicious mug cake with bulletproof coffee or another slice of keto fluffy vanilla cake.

📒 Variations

Change it up and use sugar-free chocolate chips instead of blueberries. Or, drizzle some sugar-free maple syrup on top.

This muffin in a mug is a quick and easy recipe for anyone to make when they are crunched on time.
