Kitchen Tools You’ll Need
- Mixing bowls
- Measuring cups
- Whisk
- Rubber spatula
- Muffin tin
- Muffin liners (optional)
Ingredients
- 1 cup all-purpose flour (structure)
- 1 cup almond flour (moisture and nutty flavor)
- 1 teaspoon baking soda (leavening agent)
- 1 teaspoon cinnamon (warm spice contribution)
- ¾ teaspoon salt (enhances flavor)
- ¾ cup sourdough starter, ripe or discard (adds moisture and tang)

- â…“ cup milk (moisture)

How to Make Best Sourdough Blueberry Muffins
Step 1. Start by preheating your oven to the desired temperature. Preparing the oven first ensures it’s fully heated when you put in the muffins. This step is essential for achieving the proper rise and texture that you’re aiming for.
Step 2. In a large mixing bowl, combine the all-purpose flour, almond flour, baking soda, cinnamon, and salt. Whisk these dry ingredients together until well blended. This helps to aerate the mixture, ensuring even distribution of the leavening agent and spices throughout the batter.
Step 3. In a separate bowl, mix together the sourdough starter, maple syrup or honey, milk, vegetable oil or melted butter, and egg. Whisking these ingredients together will create a cohesive wet mixture, integrating moisture and sweetness.
Step 4. Gradually add the wet mixture into the bowl of dry ingredients. Use a rubber spatula to gently fold the ingredients together. It’s best not to overmix; you want the batter to be combined with a few lumps remaining for a tender muffin consistency.
Step 5. Carefully fold the blueberries into the batter until just incorporated. If you’re using frozen blueberries, there’s no need to thaw them first; they may create a nice marbled effect in the muffins while baking.
Step 6. Line your muffin tin with liners or grease it lightly. Spoon the batter into each muffin cup, filling them about three-quarters full. This allows room for the muffins to rise without overflowing.
Step 7. Sprinkle Demerara sugar on top of each muffin for added crunch, if desired. This optional step contributes a lovely texture and a bit of sweetness on the surface, enhancing the overall experience.
Step 8. Bake the muffins in the preheated oven for about 20 to 25 minutes, or until they’re golden brown and a toothpick inserted in the center comes out clean. Keep an eye on the muffins towards the end of the baking time to avoid over-baking.
Step 9. Once baked, remove the muffins from the oven. Let them cool in the pan for a few minutes before transferring them to a wire rack. Allowing them to cool prevents steaming and keeps the bottoms from becoming soggy.

Serving Suggestions
These muffins make an excellent breakfast, especially when served warm alongside a cup of coffee or tea. They can also be enjoyed as a satisfying snack throughout the day. If you’re having family meals, they fit nicely on a brunch table or can be offered with yogurt and fresh fruit. Leftovers can be packed for school lunches or enjoyed during a quiet moment at home, making them versatile and practical.
Pro Tips for Best Results
- Measure your flour correctly. Too much flour can lead to dry muffins. Spoon the flour into your measuring cup and level it off for accuracy.
- Don’t overmix the batter. A few lumps are okay; overmixing can result in dense muffins.
- Use room-temperature ingredients. This helps create a better texture in your final muffins.
- Check for doneness with a toothpick. If it comes out clean or with a few crumbs, they’re ready.
- Adjust blueberries as desired. If you prefer a stronger blueberry flavor, feel free to add more.
- Experiment with spices. Next time, try adding nutmeg or vanilla extract for different flavor profiles.
Common Mistakes to Avoid
- Not measuring flour correctly. If flour is packed into the cup, it can lead to dry muffins. Always fluff the flour before scooping.
- Overmixing the batter. This can make muffins tough instead of tender. Mix just until combined for a lighter texture.
- Using cold ingredients. Cold eggs or milk can prevent proper emulsification. Let them come to room temperature for even mixing.
- Underbaking or overbaking. Baking times may vary; always conduct the toothpick test to ensure they’re done.
- Neglecting to cool the muffins. Cooling them directly in the pan can lead to sogginess. Transfer them to a wire rack after a few minutes.
- Being inconsistent with blueberry type. Using too many frozen blueberries can lead to a soggy texture. Consider the balance between fresh and frozen.
Variations & Substitutions
Feel free to adjust the sweetness by using less maple syrup or honey if you prefer a less sweet muffin. You could incorporate nuts for additional crunch or replace part of the almond flour with coconut flour for a different flavor. Experiment with spices too; adding a pinch of nutmeg can provide a nice twist to the traditional cinnamon flavor.
Storage & Reheating
Store muffins at room temperature in an airtight container for a couple of days. For longer storage, keep them in the refrigerator, where they can last up to a week. You can also freeze them for up to three months; just wrap each muffin tightly to maintain freshness. To reheat, pop them in the microwave for about 15-20 seconds or warm them in a toaster oven. This will help retain their soft texture.
