I have to admit, these Salted Caramel Sourdough Apple Crumble Bars Recipe, completely won me over the first time I baked them. I wasn’t expecting the sourdough twist to pair so beautifully with sweet apples and rich caramel, but it absolutely does.

Honestly, once I made these, they instantly became a go-to treat in my kitchen. You can also enjoy similar indulgent recipes like Cowboy Butter Chicken Pasta Linguine Recipe for a heartier option.
Ingredients
Here’s everything you’ll need, along with helpful tips to get the best results:
- 1 cup sourdough discard – adds a subtle tang and depth of flavor; use unfed discard for best results
- 1 ½ cups all-purpose flour – gives structure; avoid overpacking the flour when measuring
- ¾ cup brown sugar – adds moisture and a rich caramel-like sweetness
- ½ cup granulated sugar – balances the flavor and helps with texture
- ¾ cup unsalted butter (melted) – creates a soft, crumbly base; use real butter for best taste
- 1 tsp vanilla extract – enhances overall flavor
- ½ tsp salt – balances sweetness and boosts flavor
- ½ tsp baking soda – helps the base rise slightly and stay tender
- 2 medium apples (peeled and diced) – fresh apples work best; avoid overly soft varieties
- 1 tsp cinnamon – adds warmth and classic apple dessert flavor
- ½ tsp nutmeg – optional, but enhances the spice profile
- ½ cup salted caramel sauce – use thick caramel for better layering and drizzle
Note: This recipe makes approximately 9–12 bars depending on how you cut them. For a lighter side or snack, you might also enjoy Mexican Street Corn Pasta Salad Recipe alongside.

How to Make Salted Caramel Sourdough Apple Crumble Bars Recipe?
Prepare the Base
Start by preheating your oven and lining your baking pan with parchment paper. In a bowl, mix melted butter, sugars, vanilla, and sourdough until smooth. Then add flour, baking soda, and salt to form a soft dough.
Press the Crust Layer
Take about two-thirds of the dough and press it evenly into the prepared baking pan. Make sure the layer is compact and smooth so it bakes evenly. This will form the sturdy base of your bars.
Prepare the Apple Filling
In another bowl, toss the diced apples with cinnamon and nutmeg. Make sure the apples are evenly coated so every bite has a warm spice flavor. This step enhances the natural sweetness of the fruit.
Layer the Apples
Spread the apple mixture evenly over the crust layer. Try to distribute the apples well so the bars bake uniformly. This ensures every slice has a good balance of crust and filling.
Add the Crumble Topping
Take the remaining dough and crumble it over the apples. Don’t press it down—leave it loose and crumbly for a perfect texture. This creates that classic crumble top once baked.
Bake the Bars
Place the pan in the oven and bake until the top is golden brown and the apples are tender. The aroma at this stage is amazing and fills the whole kitchen. Let the bars cool completely before cutting.
Drizzle the Caramel
Once cooled, drizzle salted caramel sauce generously over the top. This adds richness and ties all the flavors together beautifully. Cut into squares and serve.
Additional Tips for Making this Recipe Better
- I always use slightly tart apples like Granny Smith because they balance the sweetness perfectly
- Don’t skip cooling completely—I learned the hard way that warm bars fall apart easily
- I like to warm the caramel slightly before drizzling for a smoother finish
- For extra texture, I sometimes add a handful of oats to the crumble topping
- If I want a stronger sourdough flavor, I let the discard sit at room temperature a bit longer before using
How to Serve Salted Caramel Sourdough Apple Crumble Bars Recipe?
These bars are incredibly versatile when it comes to serving. I love enjoying them slightly warm with a scoop of vanilla ice cream on top—the contrast is amazing. You can also drizzle extra caramel or sprinkle powdered sugar for a more elegant presentation.
For gatherings, cut them into neat squares and serve on a platter with a light dusting of cinnamon. They also pair wonderfully with a cup of coffee or tea, making them perfect for dessert or even an afternoon treat.

Make Ahead and Storage
Storing
Store the bars in an airtight container at room temperature for up to 2 days. For longer freshness, keep them in the refrigerator where they can last up to 5 days without losing flavor.
Freezing
You can freeze these bars by wrapping them individually and placing them in a freezer-safe container. They stay fresh for up to 2 months and are great for make-ahead desserts.
Reheating
