The Best Keto Blueberry Muffins

If you are after the best tasting low carb blueberry muffins, you’ve come to the right place.

There are so many keto blueberry muffin recipes out there, but none of them come close to achieving the texture of of a traditional flour-laden muffin.

This one tastes like the real deal. They are moist and fluffy in the middle with a tender crumb.

They are also simple to make and need just 6 ingredients.

Ready in under 20 minutes, you have no excuses not to make them.

Oh, and each muffin has just 3 grams of carbs.

By the way, if you want to try more keto muffins, try almond flour muffins and coconut flour muffins.

Ingredients ingredients

These blueberry muffins need just 6 ingredients to make and yield 12 standard sized muffins. They are sweetened with a low carb liquid sweetener and have no butter. Instead, we use coconut oil for that lovely texture. For this recipe, you’ll need-

  • Almond flour- use blanched almond flour, not almond meal. The blanched variety will give the muffins a tender crumb, versus the almond meal, which could be a little more gritty. 
  • Baking soda- Gives the muffins stability and structure. 
  • Salt- Brings out the sweetness of the syrup and blueberries. 
  • Coconut oil OR butter- Refined coconut oil that is in liquid form. Unsalted butter will also work.
  • Sugar free syrup- store bought or homemade keto maple syrup
  • Eggs- Room temperature. 
  • Vanilla extract- Optional, but gives a light vanilla flavor throughout. 
  • Blueberries- Fresh or frozen blueberries work. If you use the frozen variety, don’t bother thawing it first.

How to make keto blueberry muffins

Using a few ingredients makes the baking process super simple and quick. Everything is made in one bowl and if you use frozen blueberries, you don’t need to thaw them out. There are just three simple steps to whip these up.

Step 1- Make the batter

Start by making the batter by mixing the dry ingredients first, then adding the wet, then folding through the blueberries. 

Step 2- Fill the muffins

Next, fill the muffin cups by dispersing the batter amongst a 12-count muffin tin lined with muffin liners. Reserve a few extra blueberries on top of them.

Step 3- Bake the muffins

Finally, bake the blueberry muffins until they are lightly golden on top and slightly firm to touch. You can also use the skewer test to see if they are done.

Tips to make the best recipe

  • These muffins aren’t overly sweet, relying on the maple syrup and blueberries for sweetness. If you prefer a sweeter muffin, add 1-2 drops of liquid stevia. 
  • Always grease your muffin tin or silicone muffin mold. This just ensures the extra precaution that they avoid sticking to the bottom. 
  • Cooking times will depend on your oven and location. Insert a skewer around the 19-minute mark, then regularly check from there until cooked. Mine takes around 25 minutes. 
  • Reserve some extra blueberries to top the muffins with. 

Dietary swaps and flavor variations

This muffin batter is so easy to customize, you can have some fun to change up the flavors or adapt them to be suitable for other diets you may follow. Try some of these variations:

  • Use different berries, like strawberries, blackberries, or raspberries. They will still be super low in carbs! 
  • Make them eggless by using one of these egg substitutes
  • Use different extracts like coconut, orange, lemon, or cinnamon. 
  • Replace the syrup with other keto liquid sweeteners like keto honey or keto simple syrup
  • Add sugar free chocolate, like chocolate chips or white chocolate

Storage instructions

What is the best way to store keto muffins? Here are the tried and tested tips. 

  • Up to five days: Store them at room temperature in an airtight container. To ensure they remain moist, place a paper towel in the container. 
  • 1 week or more: These will keep well in the refrigerator, too. Allow them to sit at room temperature for several minutes before enjoying. 
  • 6 months: Freeze them in a ziplock bag and store them for up to 6 months.

    Oh my goodness! I tried again this morning.. these are beyond delicious .. I sprinkled a little powdered monk fruit sugar (sugar free sweetener) and slathered with butter .. I’m thinking I’m going to just eat these the rest of my keto journey.. 😂

  3. Hi! Why did you change the blueberry bread recipe when making muffins? Can’t we just make your blueberry bread recipe into muffins? I was just wondering why. Thanks so very much for your recipes.

    Oh. My. Word. These are one of the best things I’ve ever made since going low carb 4 years ago!!! These might actually be better than the sugar filled version!! I used frozen blueberries and they were so moist!! Thank you!!!!

  5. Can you melt solid coconut oil for this recipe? Or could you use MCT oil? I love your recipes – I have made 2 so far and everyone (even friends and hubby) has loved them. Not specifically Keto but looking for gluten free, vegan and vegetarian healthier recipes. Next on my list is this blueberry one.

    Okay so I admit that I have not made these yet as I just got the email with the recipe in it. That being said, 5 carbs for a full sized blue berry muffin is insane. Next time Im off, I will be trying these muffins!! Btw, they look amazing!!

    I’ve just started my keto journey, so I’m making adjustments along the way, so I can make a permanent lifestyle change. I tried the recipe and they came out so fluffy and moist. I wished they had been a little sweeter, I ended up adding honey to it since I didn’t have the syrup it called for. I tried to improvise. I’ll definitely make them again. I love the recipe, thank you! Can’t wait to check out your other recipes!! ❤️
