Low Carb Blueberry Muffin in a Mug

Sweet, tender, and bursting with blueberries, this Low Carb Blueberry Muffin in a Mug can be in your hands in less than 5 minutes! (And, you don’t even have to turn on your oven!)

Blueberries are in season in many parts of the country, so why not take advantage of seasonal produce and make this delicious blueberry muffin? (Only have frozen blueberries? No problem! See below for how to use frozen blueberries instead of fresh.)

Not only is this Blueberry Muffin in a Mug low carb (only 8 net carbs per serving), it is also dairy free, gluten free, full of fiber, and a Trim Healthy Mama S Recipe.

Benefits of Blueberries

Blueberries are high in antioxidants (higher than blackberries and strawberries).

Great for weight loss (1 cup of blueberries is low in calories but has over 3 grams of fiber).

May improve memory and cognition - they are good for your brain!

Because of their high antioxidant content, blueberries can help reduce inflammation.

Supports digestion (that high fiber content is good for your digestive tract)!

One serving has 36% of your suggested daily value of Vitamin K!

(See more information about blueberries from my source.)

Easy Blueberry Muffin Recipe

I hear requests over and over again from my readers . . . we need easy recipes that do not require a lot of ingredients.

BINGO! This recipe fits that perfectly - only a handful of ingredients and it takes less than 5 minutes to make. The greatest amount of time will probably be spent pulling the ingredients out of your pantry!

In a hurry to get out the door in the morning? Need a quick afternoon snack? This single serve Blueberry Muffin is perfect for you!

If you are a Trim Healthy Mama, you probably already have all of the ingredients needed for this recipe right in your cupboard.

And don’t worry, if you are not a THM (or if you do not use special ingredients), I have some substitutions below just for you!

And thanks to wholesome, clean ingredients, this muffin has 13 grams of protein all on its own.

But if you feel you need more protein, you can pair this muffin with some cottage cheese or Copycat Vanilla 000 Yogurt and berries.

(Or pair it with a Salted Caramel Collagen Coffee - I love this flavored collagen powder!)

Personally, I love the fact that this muffin is a single serving. I can whip one up in less than 5 minutes, and enjoy a delicious, guilt free treat!

However, if you want to make more than one, it is easy to mix up two mugs at a time, then just cook each one for 70 seconds.

Baking a Low Carb Blueberry Muffin in the oven

I know some people do not use a microwave, so if you want to bake this muffin in the oven, you can pour it into a greased ramekin or oven safe bowl, and bake for approximately 10-15 minutes at 350 degrees.

I’m sure there will be requests for a larger batch of blueberry muffins that can be baked in the oven, so I will add that to my list of recipe tests.

(If you want to make a larger batch of muffins now, check out these Blueberry Muffins with Crumb Topping from my friend Taryn, at Joy Filled Eats. Don't they look amazing?)

But for now, I’m loving the fact that I can make a “baked” treat without turning on my oven!

If you want, you can eat this muffin while it is still warm, but I prefer to let mine cool a bit before I dig in. I have tried it both ways, and found I personally like it best at room temperature.

To frost or not to frost?

I debated whether or not I should add a frosting or glaze, but I decided to just leave it simple. If you do want something to go on top, you can make a simple glaze of ½ Tablespoon of Gentle Sweet and ½ teaspoon of water.

Or if cream cheese is more your thing, mix 1 Tablespoon of softened cream cheese with ½ Tablespoon of Gentle Sweet and a dash of unsweetened almond milk.

If you love the lemon/blueberry combo, you could add in a touch of lemon zest to brighten up the flavor of this low carb muffin.

(Random fact: Personally, I do not like lemon flavor - not even lemonade! That is why you will not likely find many lemon-based recipes here on my My Montana Kitchen!)

Recipe Substitutions

If you do not have access to fresh blueberries, I believe you could use frozen just as well. However, frozen blueberries can sometimes turn the batter purple, so just be aware of that!

Trim Healthy Mama Baking Blend is a great product to keep on hand for low carb baking, but if you do not have it, you can use a blend of equal parts almond meal, coconut flour, and flax meal.

Gentle Sweet is by far my favorite low carb sweetener, but my Low Carb Powdered Sugar measures the same, and works great in this muffin.

Or you can use half the amount of Pyure in place of the Gentle Sweet. Pyure can be found at most Walmarts and grocery stores.
