The Best Blueberry Muffins Ever!

I wanted to make the HUGEST keto blueberry muffins, Starbucks style. And I did it: Just one of these keto muffins is pretty much a meal, and probably enough to satisfy all your monster muffin munchies! But, different from your usual over-priced, sugar laden coffee shop blueberry muffins, these are sugar-free, gluten-free, low-carb, and even healthy. The whole shebang!

What makes this keto muffins so good? Their light and fluffy, just right, texture. The perfect size (I used huge liners), that barely fits in your hand. The liberating feeling of eating something that is paradoxically so delicious, so simple to make, and totally guilt-free.

The most perfect blueberry muffin in the world. Yes, it is.

How easy to make, you ask? Ridiculously. Just don’t let a spoon fall inside of the running blender and remove the muffins from the oven before burning and I promise they’re gonna be perfect. And so perfect they got, every time, that I’ve made these keto muffins in several flavors and shapes and they always come out amazing!

You can make these keto blueberry muffins in different flavors and sizes

If you so wish, you can transform this blender muffin recipe into a full sized keto cake using a regular cake pan or even divide the batter and make it in the microwave, as mug cakes. Not a blueberry fan? How about some sugar-free chocolate chips instead?

You can also leave the keto blender muffins vanilla flavored only, or swap for another flavor extract, or add some cinnamon and crushed nuts. Lemon or orange peels give the batter a delicious fragrance. I tested for you. Anything goes. It’s amazing. This is my favorite, most foolproof, versatile keto muffin mix.

What are the ingredients for the best keto blueberry muffins

  • Low-carb flour mix: Almond flour, oat fiber powder and coconut flour
  • Wet mix: heavy whipping cream, butter, eggs and water – you can use almond milk if you prefer, but plain, room temperature or lukewarm water is good enough.
  • Structure: Some baking powder for hugeness, and psyllium husks to make them get their fluffy and delicious texture.
  • Flavor: A pinch of salt, some vanilla extract and blueberries!

I mixed some low-carb and keto flours for the best muffin texture and improved nutrition. Almond flour is certainly much better for you than wheat flour, but still it isn’t a good idea to consume in large quantities, not only for its caloric density, but also because of the anti-nutrients present in almonds.

I tried baking these keto blueberry muffins without psyllium husk, and the results were very different – in a bad way. I don’t have a picture, but if you’d like to see the difference that the addition of psyllium husk makes to a keto recipe, head over to our flourless keto bread recipe to check it out! It’s here.

How to make a sugar-free lemon glaze

And what about a lemon glaze? If you don’t really care for butt naked muffins, a simple sugar-free lemon glaze will elevate their looks and give these keto blueberry muffins a sweet and sour twist.

It’s super easy to make a lemon glaze in a keto friendly version – just mix together 3 ingredients:

Bathe your muffin’s tops with the glaze mixture, and let it set. Done!

The sweetener needs to be powdered, like this confectioners style, or the consistency won’t be right. If you prefer, you can make your own powdered erythritol stevia keto sweetener blend. You can see my recipe here.

How to properly juice a lemon – the easy way

To extract the most juice from a lemon – sometimes we have the stubborn ones, right? – I beat them into submission. Really, I slap the juice outta them. Some microwave their lemons, or use an easy juicing gadget, but I find the violent method more therapeutic.

If I have lots of lemons to juice, I increase my productivity by putting them inside a sock and hitting the sock against the counter, or the wall, or the floor. Like a morning star flail medieval sort of weapon swinging. It’s very relaxing, you should try.

How to make the best keto blueberry blender muffins

It’s so quick and easy! Just blend all ingredients at the highest speed, in two sets: first all the wet ingredients, and, when they are fully combined, add the dry ones. Blend away until everything is smooth and creamy, and that’s it!

This is one of the rare occasions in baking when you need not worry much about the temperature of the eggs and butter, for as long as they’re not frozen, in blending everything will grow warm and melt away.

Then you can go ahead and fill in your muffin liners. In the extra large silicone ones (jumbo sized) I used I poured 130 grams of batter in each, about 3/4 way to the rim, and one tablespoon of blueberries, about 30 grams.

Bake in a preheated oven, for about 40 minutes. For ideal keto muffin growth and smoother domes, bake at 170°C (338 °F) with fan for 15 minutes, them turn off the fan and increase to 185°C (365 °F) for 25 minutes. If making a full sized cake, the baking time is a little longer.

Finally, just choose if you want to bathe the golden keto muffin tops in lemon glaze, or serve them as they are. Either way, they will be incredibly guilt-free delicious.

What is the best blender for cake?

I made this in a 2.3 horsepower motor high speed blender. It seemed a bit overkill when I got it, but there’s glorious joy from utterly destroying everything I throw into it in a matter of seconds.

I believe that if you just have a regular blender you can achieve similar results, but you might have to blend for a very long time on the highest speed. You can stop to give your appliance a break and then continue if needed. The keto muffin batter when ready must be completely smooth and uniform, like a dream. A cream, I mean, a cream.

  1. I liked them a lot. Mine were not very sweet—I may have not used enough as I mixed my sweeteners (Lakanto gold and allulose) as I ran out of Lakanto. This was the first time using oat fiber, not sure but I think it was the ingredient that gave the muffins an almost cornbread taste/texture, particularly the muffin without much blueberries (extra batter)—the muffin with more blueberries was less so. 🙂

    1. Thank you for sharing your experience, Cin 😊 I’m so glad you liked them! Oat fiber does give a different texture to keto baking, because it’s so fine compared to the other low-carb flours. I hope you find it positive!

    1. Hi Jennene! Thanks for your question. I don’t actually have a hand mixer, only a standing mixer, which is a huge thing that I just use when I really need – for creaming butter and meringue, mostly. These muffins I mixed in a blender so that they would get extra fluffy: it’s an easy, hands free way to incorporate a lot of air into the batter, and also to make the crumb of the cake more cohesive/tight in a way (less crumbly?) because the grainier keto flours (almond, coconut) get totally smoothed out by the blending. The batter does get super creamy, and you don’t see any little lumps or grains of flour in it. You wouldn’t want to do this with regular flour muffin batter, as gluten will over develop with prolonged mixing and the muffin or cake would get hard. But these muffins (and most keto recipes) don’t have gluten, so we can mix with abandon! Anyway… I guess I’m just a fan of using a blender for keto baking! To really show you what a blender does that a hand mixer cannot (or at least I don’t think so), I’d like to share with with you this recipe for keto bread. It really shows that almost anything we throw in a blender can be baked fluffy 😉

  2. Wow, these need no more convincing! I love how they’re catered for so many people and the wonderful blueberry muffin flavor. Thanks for sharing!
