These keto blueberry muffins are my favorite way to satisfy a sweet craving while sticking with a low carb lifestyle. Packed with juicy berries and made in under fifteen minutes they are just right for breakfast or an easy snack. I have made batch after batch for neighbors and no one can ever believe they are healthy.
Ingredients
- Fine almond flour: Adds a buttery texture without gluten Look for one that is pale and finely milled for the best results
- Powdered erythritol: Naturally sweetens without the carbs Choose a brand that is zero aftertaste and check for pure powder not granulated
- Milk of choice: Moistens the batter and helps bind everything together I like using unsweetened almond milk for even fewer carbs
- Large egg: Gives structure and helps the muffins hold together If vegan use a flax egg for easy swapping
- Baking powder: Needed for lift and soft domed tops Make sure yours is fresh and lump free
- Salt: Balances the sweetness and sharpens the flavors Avoid rock salt and use fine instead
- Blueberries: Bring all the sweet tart flavor to each bite Go for fresh firm berries or wild frozen ones No need to thaw before adding
- Optional pinch cinnamon or cardamom: Adds subtle warmth and aroma If using cardamom use only a light sprinkle because it is potent
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to three hundred fifty degrees Fahrenheit and give your mini muffin tin a thorough greasing or line the cups with paper liners so nothing sticks
- Mix the Dry Ingredients:
- In a large bowl combine almond flour powdered erythritol baking powder salt and optional spices Stir really well to ensure everything is evenly distributed and there are no clumps
- Add the Wet Ingredients:
- Pour in the milk and crack in the egg or flax egg Stir well just until no streaks remain avoiding overmixing to keep the muffins tender
- Prepare the Muffin Cups:
- Scoop a spoonful of batter into each muffin cup Place a few blueberries on top of the batter in each cup then cover with another small scoop of batter to sandwich the berries Or gently press the berries on top if you want them peeking through
- Bake:
- Place the tin on the center rack and bake for thirteen minutes for mini muffins or seventeen to eighteen minutes for regular size ones The tops should look even and lightly golden
- Cool and Remove:
- Let the muffins cool in the tin for ten minutes so they firm up before handling If not using liners gently loosen each muffin with a small knife to pop out Paper liners peel off even more easily once the muffins have rested for a day

My favorite thing about these muffins is how the blueberries burst and turn jammy inside the soft crumb Whenever I make these with my kids they love pressing the berries into the batter and watching them pop in the oven
Storage Tips
Keto blueberry muffins stay moist on the counter for up to two days in an airtight container If you will not finish them quickly I recommend freezing Once cooled layer the muffins between sheets of parchment in a container or zip top bag and freeze for up to three months Let thaw at room temperature for an hour or microwave gently to rewarm
Ingredient Substitutions
Try swapping the blueberries for low carb raspberries or chopped strawberries for a new twist If you are out of almond flour hazelnut flour works though it will give a more pronounced nutty flavor Erythritol can be swapped for monkfruit sweetener or a touch more stevia based on your preference
Serving Suggestions
Pair these muffins with a dollop of keto whipped cream for an afternoon treat or tuck one alongside your morning coffee They are also perfect for packing in school or work lunch boxes for healthy snacking
