Caramel Apple Crumble Bars are my go-to treat for fall gatherings and cozy weekends They combine tender apples hidden beneath a buttery oat crumble and gooey caramel threads Every batch smells like autumn and disappears quicker than I can brew cider
I started baking these bars one chilly October day when my daughter brought home a bushel of apples They became an instant family favorite and now we bake them together every year
Ingredients
- Apples: fresh and firm Granny Smith keep the bars from getting mushy sweeter kinds work for a gentler flavor
- All-purpose flour: creates a sturdy crumb base sift to avoid lumps
- Old-fashioned oats: add crunch and wholesome heartiness choose rolled oats for best texture
- Light brown sugar: lends depth and richness to both crust and crumble
- Butter: unsalted for creamy flavor and better control of salt quality butter means a more tender crumb
- Ground cinnamon: rounds out flavors and brings warmth use freshly ground or trusted brands for best aroma
- Caramel sauce: homemade or store-bought thick is best choose quality brands for a true caramel burst
- Vanilla extract: smooths out flavors good vanilla makes every layer sing
- Salt: just a pinch enhances everything look for fine sea salt or kosher
Instructions
- Prepare the Crumble Base and Topping:
- Combine flour oats brown sugar and salt in a large bowl Mix thoroughly so every oat and grain is coated evenly Cube cold butter and rub it into the mixture using your fingertips until it looks like coarse sand leaving some larger buttery clumps Set aside half for the crumble topping the rest forms your base
- Press and Bake the Base:
- Line a square baking pan with parchment for easy removal Firmly press half the crumble mixture into the bottom of your pan packing down so the base holds together Bake at 350 degrees for about 12 minutes until lightly set but still pale This prevents sogginess later
- Make the Spiced Apple Filling:
- Peel and core apples then chop into small even cubes Toss apples with cinnamon brown sugar and a small splash of vanilla Make sure every piece is coated so the flavors are balanced Let them sit briefly to release juices This infuses the apples with spice before baking
- Layer Apples and Caramel:
- Spread spiced apples evenly over the slightly cooled base Drizzle caramel generously over apples ensuring coverage in every corner This helps every slice have that signature gooey bite
- Add the Crumble Topping:
- Scatter the reserved crumble over apples and caramel Press down gently so bits adhere but the topping remains craggy for texture
- Bake to Golden Perfection:
- Bake bars for 30 to 35 minutes at 350 degrees until the oats are golden and the apple layer bubbles gently on the edges Cool in the pan for at least an hour before slicing so squares stay neat and the caramel sets

My favorite ingredient is the caramel especially when I spoon it over fresh apple slices Studying my grandmother bake this recipe still reminds me of autumn afternoons with laughter and cinnamon filling the house She always said the crumble is the secret to happy hearts
