What You Need To Make Keto Blueberry Muffins
With a hint of lemon and loads of plump blueberries, these low-carb muffins are a quick and easy morning treat. This is what you’ll need to make them:
- Butter – I used salted butter
- Granulated sugar substitute – use your favorite blend and brand. I used monkfruit in this keto blueberry muffin recipe
- Eggs
- Heavy whipping cream (or almond milk)
- Vanilla extract
- Lemon juice
- Almond flour – superfine grind is what works best in this recipe
- Oat fiber – see more about oat fiber down below
- Baking soda
- Salt
- Lemon zest
- Fresh blueberries
What is Oat Fiber?
Oat fiber comes from grinding the outside of the oats, or the hull. Is oat fiber keto? It is insoluble fiber, and as such, it is TOTALLY keto-friendly and an amazing source of fiber. Who on a keto diet doesn’t need more fiber?
Oat fiber and oat flour are not to be confused. Oat fiber has 0 net carbs. It starts with 3 grams of carbs per teaspoon, and has 3 grams of fiber. That puts it at 0 net carbs per teaspoon.
I like using oat fiber because it not only adds more fiber but it helps give foods a texture that’s closer to real flour. Almond flour is great, but there’s no mistaking it for almonds.
Oat fiber is more absorbent than coconut flour or almond flour, so this recipe needs a bit more liquid than another might need.
What is almond flour?
Also called almond meal and blanched almond flour, almond flour isn’t really flour at all. It’s given the name flour because it looks something similar to regular wheat flour and it is used in many keto recipes in place of flour.
Almond flour will work instead of wheat flour in some recipes, but not all. It has no gluten or thickening properties so it won’t make bread or thicken sauces.
How To Make Easy Keto Blueberry Muffins
For a full list of ingredients and instructions to make these almond flour blueberry muffins, please scroll down to the bottom of this page to the recipe card.
- Spray a muffin tin with nonstick cooking spray or line it with muffin cups. Preheat the oven to 350-F.
- With a hand-mixer, whip the butter and sugar substitute until it is light and fluffy. Add the eggs, beating well after each egg.
- Add the heavy whipping cream, vanilla, and lemon juice and mix well with the hand-mixer.
- In another bowl, combine the almond flour, oat fiber, baking soda, and lemon zest.
- Add the dry ingredients to the wet ingredients and mix well with a large spoon. No need to use the beaters.
- Fold in the blueberries, mixing carefully to not smush them.
- Divide the batter evenly between the muffin cups making sure that each gets a fair share of blueberries.
- Bake at 350-F for about 15 minutes. Test if the muffins are done by inserting a toothpick. It should come out pretty clean. A few clingy crumbs are fine.
- Let cool and enjoy!
Chef Jenn’s Tips
- Use raspberries or blackberries (both keto-friendly berries) in this recipe instead of blueberries to change it up in this gluten-free muffin recipe
- Don’t overmix the batter – like any baked treat, it needs a gentle hand
- The baking soda is what makes these muffins rise up so nicely, so don’t skip the lemon juice because it activates the leavening of the baking soda
- Make these blueberry keto muffins ahead of time for a quick breakfast
Can I Freeze These Low-Carb Blueberry Muffins?
Yes! They freeze like a dream! Pop them into an airtight container or zipper-top plastic bag and freeze for up to a month (or longer.) Then, just thaw and enjoy!

I’m always in the kitchen creating new recipes, and while some of them are big hits, I get some misses, too. But these are some of my favorite all-time recipes:
- Thick and luscious Salmon Chowder
- Grilled veggies – I love how versatile this recipe is!
- This amazing cauliflower dish
- Meaty sausage Parmigiana
This recipe is delicious. The muffins turn out perfectly moist and sweet. This has become my favorite afternoon treat.
I have family members who eat keto-only and I made these and they were such a huge hit! I loved them, too. The blueberries come through so well and they baked up perfectly.
My hardcore ketovore boyfriend is going to LOVE that i whipped these up for him. He uses a gold monk fruit erythritol sweetener, will that work as the ‘sugar’?
These are great with dinner, for breakfast and as a mid-afternoon snack! Absolutely love these delicious muffins!
Delightful. Even my non-keto family members gobbled them up. These are definitely a keeper.
