Ingredients for Keto Blueberry Muffins
- 2 cups blanched almond flour (ensure it’s finely ground for best texture)
- ¼ teaspoon salt
- ½ teaspoon baking powder
- ¼ cup oil (we recommend avocado oil, but coconut oil or melted butter works too)
- ¼ cup sugar-free maple-flavored syrup (or your preferred keto-friendly sweetener)
- 3 large eggs (room temperature for easier mixing)
- 1 teaspoon fresh lemon zest (optional but adds a bright flavor)
- ½ cup blueberries (fresh or frozen—no need to thaw if using frozen)
Step-by-Step Instructions
- Preheat the oven to 350°F (180°C). Line a cupcake pan with 12 paper liners and set aside.
- In a large mixing bowl, whisk together the almond flour, salt, and baking powder until well combined.
- Add the oil, sugar-free syrup, eggs, and lemon zest to the dry ingredients. Mix until the batter is smooth and fully combined.
- Gently fold in the blueberries to distribute them evenly throughout the batter.
- Spoon the batter evenly into the prepared paper liners, filling each about ¾ full.
- Bake in the preheated oven for 20–22 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean.
- Remove the muffins from the oven and let them cool in the pan for 5–10 minutes before transferring to a wire rack.
- Serve warm or store in an airtight container at room temperature for up to 3 days.
Delicious Topping Ideas for Keto Blueberry Muffins
Take your muffins to the next level with a drizzle of sugar-free glaze made from powdered erythritol and almond milk. For a crunchy twist, sprinkle chopped nuts like pecans or almonds on top before baking. If you’re feeling indulgent, a dollop of whipped coconut cream pairs perfectly with the tangy blueberries.
How to Store and Reheat for Freshness
Store your muffins in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days. To reheat, pop them in the microwave for 10-15 seconds or warm them in a 300°F (150°C) oven for 5 minutes. For longer storage, freeze them in a freezer-safe bag for up to 3 months—just thaw at room temperature before enjoying!
Recipe Variations to Mix It Up
Swap blueberries for raspberries or blackberries for a different berry twist. If you’re a chocolate lover, fold in sugar-free chocolate chips instead of fruit. For a nut-free version, replace almond flour with sunflower seed flour—just note it may turn slightly green due to a natural reaction with baking powder!
Time-Saving Tips for Busy Bakers
Prep your dry ingredients in advance and store them in a ziplock bag for quick mixing later. Use a cookie scoop to evenly portion the batter into liners—it’s faster and less messy. If you’re short on time, skip the lemon zest and use 1 teaspoon of lemon extract instead for a similar citrusy kick.
Common Questions Answered
Can I use coconut flour instead?
No, coconut flour absorbs more liquid and requires different ratios. Stick to almond flour for this recipe.
Can I skip the sweetener?
Yes, but the muffins will be less sweet—perfect if you prefer a more tart flavor.
Why are my muffins dense?
Overmixing the batter can cause this—gently fold ingredients until just combined for a lighter texture.
