Low Carb Blueberry Muffins are the kind of sweet, satisfying treat that makes low-carb baking feel easy and delicious. These muffins use soy flour, a sugar substitute, heavy cream, club soda, eggs, and blueberries to create a tender muffin with golden tops and bursts of juicy berry flavor.
What makes this recipe special? It gives you a bakery-style muffin feel without using traditional flour or regular sugar. The soy flour creates the base, the sugar substitute adds sweetness, and the blueberries bring fresh fruity flavor in every bite.
Ready in about 40 minutes, these muffins are perfect for breakfast, brunch, snacks, or anytime you want a low-carb baked treat that still feels cozy and homemade.
Why You’ll Love These Low Carb Blueberry Muffins
Why are muffins such a comforting favorite? Because they’re easy to grab, easy to serve, and perfect with coffee, tea, or a simple breakfast plate.
These Low Carb Blueberry Muffins are lightly sweet, soft, and filled with blueberries. The batter comes together quickly with a whisk, and the muffins bake until the tops are golden brown and a toothpick comes out clean.
I love how flexible this recipe is. You can keep it classic with blueberries, or change the flavor with raspberries, blackberries, lemon extract, almond extract, cranberries, pumpkin, banana extract, walnuts, or poppy seeds.
The secret tip? Coat the muffin tin with the wheat bran and soy flour mixture. This helps prevent sticking and gives the muffins a better release after baking.

What Ingredients Are in Low Carb Blueberry Muffins?
These muffins use a low-carb baking base with soy flour, sugar substitute, eggs, cream, and club soda. The blueberries add a naturally fruity flavor and a little sweetness.
You’ll need:
Vegetable oil cooking spray
2 tablespoons wheat or oat bran and 1 tablespoon soy flour, mixed together
1 cup soy flour
½ cup sugar substitute, such as Splenda
1 teaspoon baking powder
2 eggs
½ cup heavy cream
⅓ cup club soda
½ cup blueberries
1 tablespoon sugar substitute, optional, if blueberries are not sweet
Ingredient Notes
Vegetable oil cooking spray helps grease the muffin tin so the muffins do not stick.
The wheat or oat bran and soy flour mixture is used to coat the muffin cups. This helps the muffins release more easily after baking.
Soy flour replaces traditional flour and helps keep the recipe lower in carbs.
Sugar substitute adds sweetness without using regular sugar. Splenda is one recommended option.
Baking powder helps the muffins rise and gives them a lighter texture.
Eggs help bind the batter and give the muffins structure.
Heavy cream adds richness, moisture, and a tender crumb.
Club soda helps lighten the batter and gives the muffins a softer texture.
Blueberries add juicy bursts of flavor. If they are not very sweet, sprinkle them with a little sugar substitute before adding them to the batter.
How to Make Low Carb Blueberry Muffins
These muffins are simple to mix, bake, and enjoy. The key is preparing the pan well so the muffins release cleanly.
Preheat the Oven
Preheat the oven to 375 degrees F.
This gives the muffins the right heat to rise and turn golden brown.
Prepare the Muffin Tin
Spray a 6-cup muffin tin with vegetable oil cooking spray.
Evenly sprinkle the pan with the wheat or oat bran and soy flour mixture.
Make sure to coat the sides of the muffin cups too. This helps prevent sticking.
Mix the Batter
In a bowl, use a wire whisk to mix the soy flour, sugar substitute, baking powder, eggs, heavy cream, and club soda.
Whisk until the batter is well blended.
Fold in the Blueberries
Gently fold the blueberries into the batter.
Try not to crush them as you stir.
If the blueberries are not very sweet, sprinkle them with 1 tablespoon of sugar substitute before folding them in.
Fill the Muffin Cups
Divide the batter evenly among the 6 prepared muffin cups.
Do not overfill the cups, since the muffins need room to rise.
Bake Until Golden
Place the muffin tin on the center rack of the oven.
Bake for 20 to 25 minutes, or until the tops turn golden brown.
A toothpick inserted into the center should come out clean.
Cool Before Refrigerating
Remove the muffins from the oven.
Let them cool before refrigerating.
Serve and Enjoy
Serve the muffins warm with butter or cold with cream cheese.
Both ways are delicious.
Why Use Soy Flour in Low Carb Muffins?
Soy flour is used as a lower-carb alternative to traditional flour.
It gives the muffins structure while helping keep the recipe more low-carb friendly. Because soy flour behaves differently than all-purpose flour, the texture will be a little different from classic bakery muffins, but still satisfying and flavorful.
It also browns well, which helps the muffin tops turn golden.
Why Add Club Soda to Muffin Batter?
Club soda helps lighten the batter.
The bubbles can help create a softer texture, especially in low-carb baking where alternative flours can sometimes feel dense.
It is a simple ingredient, but it helps make the muffins less heavy.
Can You Use Frozen Blueberries?
Yes, you can use frozen blueberries.
Add them straight from the freezer and fold them gently into the batter. Do not thaw them first, because thawed berries can release extra liquid and turn the batter streaky.
The bake time may need a minute or two longer if using frozen berries.
Can You Make These Muffins Ahead of Time?
Yes, Low Carb Blueberry Muffins are a great make-ahead option.
Bake the muffins, let them cool, and store them in the refrigerator until ready to serve.
They are easy to grab for breakfast, snacks, or a quick low-carb treat during the week.
How to Store Low Carb Blueberry Muffins
Store cooled muffins in an airtight container in the refrigerator.
They will keep well for several days.
Because these muffins contain blueberries, eggs, and cream, refrigerating them is the best option for freshness.
Can You Freeze Low Carb Blueberry Muffins?
Yes, these muffins can be frozen.
Let them cool completely, then wrap each muffin tightly or place them in a freezer-safe container.
Freeze for up to 2 months.
Thaw in the refrigerator or at room temperature before serving.
How to Reheat Low Carb Blueberry Muffins
To enjoy them warm, reheat muffins gently in the microwave for a few seconds.
You can also warm them in a low oven until heated through.
Serve with butter, cream cheese, or your favorite low-carb spread.
What to Serve With Low Carb Blueberry Muffins
These muffins are delicious on their own, but they also pair well with simple breakfast favorites.
Serve them with butter, cream cheese, Greek yogurt, scrambled eggs, bacon, sausage, coffee, tea, or a low-carb smoothie.
For a sweeter treat, add a little sugar-free whipped cream or a drizzle of keto-friendly syrup.
