This Apple Crisp Sourdough Loaf combines the cozy flavors of baked apples, cinnamon, and a crunchy oat topping with the tangy richness of sourdough. It’s soft, moist, and perfect for fall mornings, cozy desserts, or afternoon coffee breaks. A simple and satisfying recipe you’ll bake again and again.
Preheat your oven to 350°F (175°C). Grease or line a 9x5-inch loaf pan with parchment paper.
Make the Topping
In a small bowl, combine oats, flour, brown sugar, and cinnamon. Cut in cold butter until the mixture looks crumbly. Chill while preparing the loaf batter.
Mix Wet Ingredients
In a large bowl, whisk together melted butter, brown sugar, eggs, vanilla extract, and sourdough discard until smooth and creamy.
Combine Dry Ingredients
In a separate bowl, whisk flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Add the dry ingredients to the wet mixture and stir until just combined.
Fold in Apples
Gently fold in diced apples. The moisture from the apples keeps the loaf tender.
Assemble and Bake
Pour the batter into the loaf pan and spread evenly. Sprinkle the oat topping over the surface.
Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.
Cool and Serve
Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack. Cool completely before slicing.
Notes
Don’t overmix the batter — stir until ingredients are just combined.
Use firm apples (like Granny Smith or Honeycrisp) for best texture.
Refrigerate the topping before baking for extra crispness.
This loaf tastes even better the next day as flavors deepen.
