Keto Blueberry Muffins (Low-Carb Almond Flour Muffins)

This is the muffin I make when I want blueberries in something I can actually eat for breakfast on keto, not just a smoothie. Almond flour and oat fiber give these a crumb that isn’t eggy or dense, which is where a lot of keto muffins go wrong.

Are blueberries even keto? You bet they are! They’re one of the fruits that are lower in natural sugars making them a great pick on a keto lifestyle. They do have some natural sugars, however, so do eat them in moderation. But, a keto Blueberry Muffin in the mornings won’t throw off your numbers so grab that butter and dig in!

Chef Jenn’s Takes on Keto Blueberry Muffins

A lot of keto muffins made with almond flour alone end up tasting eggy, since almond flour has no gluten or starch to hold the crumb together and the eggs end up doing all the work. Oat fiber is the fix here. It has zero net carbs on its own and adds the kind of texture almond flour can’t give you by itself, closer to what a wheat flour muffin actually feels like when you bite into it.

The other detail that matters is the lemon juice. It’s not there for flavor, it’s there to activate the baking soda, and skipping it is the most common reason a batch comes out flat and dense instead of properly risen. Fold the blueberries in gently at the very end, and use a large spoon rather than a mixer for this step so you don’t crush them and bleed color through the whole batter before it goes in the oven.

What You’ll Love About Keto Blueberry Muffins

• These aren’t eggy the way a lot of almond flour muffins are, so they actually taste like a blueberry muffin instead of a baked omelet with fruit in it.
• They freeze well, so a weekend batch turns into breakfast for the rest of the week without any extra effort on a weekday morning.
• Non-keto people in my house eat these without complaint, which is the real test for whether a keto baked good is actually good.

Ingredients

• 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 – Fresh squeezed. This activates the baking soda, don’t skip it.
• Almond flour – Superfine grind is what works best in this recipe.
• Oat fiber
• Baking soda – Standard, needs the lemon juice to activate.
• Salt
• Lemon zest – From the same lemon you’re juicing.
• Fresh blueberries – Fresh or frozen, equal measure either way.

How To Make Easy Keto Blueberry Muffins

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!

Make IT A Meal

These are built for breakfast, not as a whole meal on their own. Pair one with Baked Eggs Florentine with Ham for actual protein alongside the sweet side of the plate.

If you’re doing a muffin-forward breakfast spread, these work well next to a batch of Keto Cinnamon Muffins so there’s a fruit option and a spiced option on the table.

Storage

These freeze well. Store in an airtight container or freezer bag for up to a month, then thaw at room temperature before eating. In the fridge, they’ll keep for about 5 days in an airtight container.
