This Crockpot Apple Crisp is warm, buttery, and loaded with tender cinnamon apples beneath a golden oat topping. Set it and forget it in your slow cooker for the ultimate easy fall dessert.

Picture this: the whole house smells like warm cinnamon apples and toasted oats, and you did not turn on the oven once. That is the quiet magic of this Crockpot Apple Crisp, and it might just become your most-requested dessert from October through March.
This recipe leans on the convenience of apple pie filling to make the whole process nearly effortless, but if you have fresh apples on hand, those work beautifully too. Either way, you get bubbling, spiced fruit beneath a buttery oat crumble that tastes like you spent far more time than you actually did. It is the kind of easy crockpot dessert that earns compliments at potlucks, family dinners, and cozy Sunday nights at home.
Getting the texture right in a slow cooker comes down to a couple of key things: the quality of your oats and the way you manage moisture. Old-fashioned rolled oats hold their shape and give you that satisfying crisp bite, while the right slow cooker size ensures even heat distribution across the filling. Using the right tools really does make the difference between a mushy topping and a golden, crumbly one.
Slow cooker apple crisp is a naturally forgiving dessert, but a few intentional choices make this version stand out.
Chef's Tip: Do not be tempted to lift the lid during cooking. Every peek releases heat and adds 15 to 20 minutes to your cook time. Trust the process.
Both options are genuinely great, and the choice really depends on how much time you have.
Canned apple pie filling is the weeknight hero here. Two 21-ounce cans fill the slow cooker perfectly, and the sauce is already thickened and seasoned. This is the version that makes this a true crockpot apple crisp easy enough for any night of the week.
Fresh apples give you more control over sweetness and texture. Granny Smith apples hold their shape best and add a pleasant tartness that cuts through the sweet crumble. Honeycrisp apples are another excellent choice for a naturally sweeter result. If you go fresh, toss the slices with a tablespoon of cornstarch so the juices thicken up properly during cooking.
The classic move is a generous scoop of vanilla ice cream right on top of a warm bowl, letting it melt slightly into the bubbling apples. Whipped cream is a lighter option that works just as well. For something a little more indulgent, a drizzle of salted caramel sauce over the top takes this already-delicious crock pot apple crisp completely over the edge.
This recipe is also a dream for entertaining. The slow cooker keeps it warm on the LOW setting for up to an hour after it is done, which means your dessert is ready when your guests are, without any last-minute rushing.

This Crockpot Apple Crisp is warm, buttery, and loaded with tender cinnamon apples beneath a golden oat topping. Set it and forget it in your slow cooker for the ultimate easy fall dessert.
Lightly grease the inside of a 6-quart slow cooker with nonstick cooking spray or a thin layer of softened butter.
Pour the apple pie filling into the bottom of the slow cooker. Stir in the vanilla extract and 0.5 tsp of the cinnamon. Spread into an even layer.
In a large mixing bowl, combine the rolled oats, flour, brown sugar, granulated sugar, remaining 1 tsp cinnamon, nutmeg, and salt. Whisk briefly to combine.
Scatter the cold cubed butter over the oat mixture. Use your fingertips or a pastry cutter to work the butter in until the mixture resembles coarse, clumpy crumbs. If using coconut, fold it in now.
Sprinkle the oat crumble topping evenly over the apple filling in the slow cooker. Do not press it down.
Place a double layer of paper towels or a clean kitchen towel under the slow cooker lid before closing. This absorbs condensation and keeps the topping from getting soggy.
Cook on HIGH for 2 to 2.5 hours or on LOW for 3 to 3.5 hours, until the topping looks set and the apple filling is bubbling around the edges.
Remove the lid and let the crisp rest for 10 to 15 minutes before serving. This allows the topping to firm up slightly.
Serve warm scooped into bowls, topped with vanilla ice cream or whipped cream.
Leftovers stay fresh in an airtight container in the refrigerator for up to 4 days. The topping softens a bit after sitting, but the flavor only gets better. Reheat individual servings in the microwave for 60 to 90 seconds.
To get ahead of things, you can mix the dry crumble topping up to 2 days in advance and store it in a sealed bag at room temperature. When you are ready to cook, just dump the filling into the slow cooker, sprinkle on the topping, and let it go. Weeknight dessert has never been simpler.
