Ingredients
For the Loaf
- ½ cup (120g) sourdough discard, unfed
- ½ cup (115g) unsalted butter, softened
- ¾ cup (150g) granulated sugar
- 2 large eggs
- ½ cup (120g) sour cream or plain Greek yogurt
- 1 teaspoon vanilla extract
- 1½ cups (180g) all-purpose flour
- 1½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
For the Apple Filling
- 2 medium apples, peeled, cored, and finely diced
- 2 tablespoons brown sugar
- 1 teaspoon ground cinnamon
For the Cinnamon Swirl
- ⅓ cup brown sugar
- 1 teaspoon ground cinnamon
For the Glaze
- ½ cup powdered sugar
- 1–2 tablespoons milk or cream
- ½ teaspoon vanilla extract
Step 1: Prepare the Apples
Peel and core the apples, then cut them into small pieces.
Add the diced apples to a bowl with the brown sugar and cinnamon. Toss until the apples are evenly coated.
Let the mixture sit while you prepare the batter. This allows the apples to absorb the cinnamon and sugar and develop more flavor.
Firm apples such as Granny Smith, Honeycrisp, or Fuji work especially well because they hold their shape during baking.
Step 2: Prepare the Batter
Preheat your oven to 350°F (175°C).
Grease a 9×5-inch loaf pan and line it with parchment paper, leaving some paper hanging over the sides. This will make the finished loaf much easier to remove.
In a large bowl, beat the softened butter and granulated sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Add the sour cream or Greek yogurt, vanilla extract, and sourdough discard. Mix until the wet ingredients are smooth and evenly combined.
Step 3: Mix the Dry Ingredients
In another bowl, whisk together:
- All-purpose flour
- Baking powder
- Baking soda
- Salt
Slowly add the dry mixture to the wet ingredients.
Fold gently until just combined. Do not overmix the batter. A few small streaks of flour are fine, as the batter will continue to come together when layered.
Overmixing can make the loaf dense instead of soft and tender.
Step 4: Make the Cinnamon Sugar
In a small bowl, mix the brown sugar and cinnamon.
This simple mixture creates the sweet cinnamon layer that gives the loaf its apple-fritter flavor.
Step 5: Layer the Loaf
Spread about half of the batter into the prepared loaf pan.
Add half of the cinnamon-sugar mixture over the batter. Then add half of the prepared apples.
Spread the remaining batter over the first layer.
Top with the remaining apples and cinnamon sugar.
Use a butter knife or thin spatula to gently swirl through the batter. A few gentle movements are enough. Do not mix the layers completely.
The goal is to create ribbons of cinnamon and apple throughout the loaf.
Step 6: Bake
Place the loaf in the preheated oven and bake for 50–60 minutes.
Check the center with a toothpick or wooden skewer. It should come out clean or with a few moist crumbs attached.
If the top becomes too dark before the center is fully baked, loosely cover the loaf with aluminum foil during the last 15 minutes.
Because the apples add moisture, baking time can vary slightly from oven to oven.
Step 7: Cool the Loaf
Remove the loaf from the oven and let it cool in the pan for about 15–20 minutes.
Use the parchment paper to carefully lift the loaf from the pan and transfer it to a wire rack.
Let it cool further before adding the glaze.
Cooling the loaf helps it firm up and makes slicing much easier.
Step 8: Make the Glaze
Add the powdered sugar to a small bowl.
Pour in 1 tablespoon of milk or cream and add the vanilla extract.
Whisk until smooth.
If the glaze is too thick, add a little more milk. If it becomes too thin, add a small amount of powdered sugar.
You want a smooth glaze that can easily be drizzled over the loaf.
Step 9: Glaze and Serve
Once the loaf has cooled for at least 20 minutes, drizzle the vanilla glaze over the top.
For a thicker glaze, allow the loaf to cool completely before adding it.
Let the glaze sit for a few minutes before slicing.
Cut the loaf into thick slices and serve.
Tips for the Best Apple Fritter Loaf
Use firm apples: Soft apples can break down too much during baking. Granny Smith, Honeycrisp, and Fuji are good choices.
Keep the apple pieces small: Small pieces spread more evenly throughout the loaf and make every slice easier to eat.
Don’t overmix: Mix the batter only until the flour disappears. Too much mixing can create a heavy loaf.
Use room-temperature ingredients: Soft butter and room-temperature eggs blend more easily and help create a smooth batter.
Don’t skip the cinnamon layer: The brown sugar and cinnamon mixture gives the loaf its classic apple-fritter taste.
Let it cool before slicing: The inside needs time to set. Cutting it while very hot can make the center seem too soft.
Can I Use Cold Sourdough Discard?
Yes. Cold sourdough discard can be used in this recipe.
Since this is a quick bread, the discard does not need to be active or recently fed. It is mainly added for flavor and to help reduce sourdough waste.
Make sure your discard smells pleasantly tangy. If it has an unusual smell or looks spoiled, do not use it.
Can I Use Greek Yogurt Instead of Sour Cream?
Yes. Plain Greek yogurt works well as a substitute for sour cream.
Both ingredients add moisture and a little tang, helping the loaf stay soft.
Use the same amount: ½ cup (120g).
Storage
Keep the cooled loaf in an airtight container at room temperature for up to 2–3 days.
For longer storage, refrigerate it for up to about 1 week.
You can also freeze the loaf. Wrap individual slices tightly and place them in a freezer-safe bag or container.
Thaw slices at room temperature or warm them gently before serving.
Serving Ideas
This apple loaf is delicious on its own, but you can make it even better with a few simple additions.
Serve a slice with:
- Hot coffee
- Black tea
- A glass of cold milk
- Vanilla ice cream
- Whipped cream
- A little salted butter
- Extra cinnamon on top
For dessert, warm a slice for a few seconds and serve it with vanilla ice cream. The warm apple and cinnamon flavor pairs beautifully with the cold, creamy ice cream.
Recipe Variations
Add Chopped Nuts
Add ½ cup of chopped pecans or walnuts to the apple layer for extra crunch.
Add More Spice
For a warmer flavor, add a pinch of nutmeg or a little ground ginger to the cinnamon mixture.
Make It Extra Glazed
If you love a sweet apple-fritter finish, make a little extra glaze and drizzle it over the loaf just before serving.
Add Raisins
A small handful of raisins can also be added to the apple layer for extra sweetness and texture.

This Apple Fritter Sourdough Discard Loaf is an easy and delicious way to turn leftover sourdough discard into something special.
