These Apple Cinnamon Sourdough Muffins are a tasty treat! They’re soft, fluffy, and packed with sweet apples and warm cinnamon. Perfect for breakfast or a snack!
I love how easy these muffins are to whip up with leftover sourdough starter. They fill the kitchen with delicious smells and disappear quickly—it’s hard to eat just one! 🍏
Key Ingredients & Substitutions
Sourdough Starter: Whether using discard or active starter, both work well. If you don’t have sourdough, plain yogurt or buttermilk can add a tangy flavor, but adjust the liquid in the recipe slightly.
Flour: All-purpose flour is a go-to. If you’re gluten-free, a 1:1 gluten-free flour blend can work. I’ve had great success using whole wheat flour for added nutrition!
Granulated Sugar: Regular sugar is fine, but you can use brown sugar for a deeper flavor. Coconut sugar is another good option for a healthier alternative.
Apples: Granny Smith is my favorite for tartness. If they’re not available, Fuji or Honeycrisp can be sweeter options. Diced pears can also add a lovely alternative.
What’s the Best Way to Ensure Tender Muffins?
To keep your muffins soft and fluffy, avoid overmixing when combining wet and dry ingredients. Stir just until you see no dry flour. This prevents gluten from forming too much, which can lead to tough muffins.
- Mix gently and use a spatula for folding in those apples—you want them spread throughout without breaking them down.
- Muffin batter is forgiving! You can even leave a few lumps if needed.

- 1 cup all-purpose flour
- 1/2 cup rolled oats (plus extra for topping)
- 1/2 cup granulated sugar
- 1 tsp baking soda

- 1 1/2 tsp ground cinnamon
- 1/4 tsp salt

How Much Time Will You Need?
This recipe will take about 10 minutes for preparation and 20-25 minutes for baking. In total, you’ll need around 35 minutes to enjoy your freshly baked muffins!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 375°F (190°C). While it heats up, line a muffin tin with paper liners or grease it well to prevent sticking.
2. Mix the Wet Ingredients:
In a large bowl, combine the sourdough starter, vegetable oil (or melted butter), egg, and vanilla extract. Whisk these together until everything is smooth and well mixed.
3. Combine the Dry Ingredients:
In a separate bowl, whisk together the all-purpose flour, rolled oats, granulated sugar, baking soda, baking powder, ground cinnamon, and salt. Mixing these ingredients well ensures that your muffins will have a consistent flavor and texture.
4. Combine Wet and Dry Ingredients:
Slowly add the dry mixture to the bowl with the wet ingredients. Use a spatula or wooden spoon to gently fold the mixtures together. Be careful not to overmix; it’s okay if there are a few lumps!
5. Add the Apples:
Gently fold in the diced apples, making sure they’re evenly distributed throughout the batter.
6. Pour into Muffin Cups:
Evenly divide the muffin batter among the prepared muffin cups, filling each one about 3/4 full. If you like, sprinkle some extra rolled oats on top for a nice texture.
7. Bake the Muffins:
Place the muffin tin in the oven and bake for 20-25 minutes, or until a toothpick inserted into the center of a muffin comes out clean and the tops are golden brown.
8. Cool and Serve:
Once cooked, remove the muffins from the oven and let them cool in the tin for about 5 minutes. After that, transfer them to a wire rack to cool completely.
9. Add a Sweet Touch:
If you’d like, dust the tops of the muffins with powdered sugar before serving for a lovely finishing touch.
10. Enjoy:
These muffins can be enjoyed warm or at room temperature. They’re perfect for breakfast or as a cozy snack! If you have leftovers, store them in an airtight container for 2-3 days, or freeze for longer storage.
Enjoy your deliciously moist and fragrant Apple Cinnamon Sourdough Muffins!
Can I Use Frozen Apples for This Recipe?
Yes! If using frozen apples, make sure to thaw and drain any excess moisture before dicing and adding them to the batter. This will help prevent the muffins from becoming soggy.
Can I Make These Muffins Vegan?
Absolutely! Substitute the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water) and use a plant-based oil like coconut or canola oil instead of butter. The muffins will still turn out delicious!
How Do I Store Leftover Muffins?
To keep your muffins fresh, store them in an airtight container at room temperature for up to 3 days. You can also freeze them for up to 3 months. Just let them cool completely, then wrap individually in plastic wrap before placing in a freezer bag.
Can I Add Nuts or Other Mix-Ins?
Definitely! Chopped walnuts, pecans, or even chocolate chips make great additions. Just fold them in along with the diced apples to create a custom twist on the classic muffin.
