Crustless Apple Pie with Brown Sugar Crumble
A crustless apple pie gives you all the warm, spiced apples you crave without rolling a single sheet of dough. The filling bakes into a soft, jammy layer and the buttery oat crumble on top adds a crisp, golden finish that a traditional crust just can’t match.
It comes together in one dish and fills the kitchen with cinnamon and baked apples. A quick slice of this, still warm from the oven, is hard to beat after a long day.
Why This Pie Works
The apples stay tender and saucy, held together with just enough flour to give the filling a silky, sliceable texture. The crumble adds a nutty, buttery crunch without needing any pastry skills.
I love that the sweetness feels balanced. Brown sugar brings a deep molasses note, and a pinch of salt keeps the filling from tasting flat. Plus, the ingredient list is short and uses mostly pantry staples.
Ingredients
- 6 large Granny Smith apples (about 2½ lbs): their tartness stands up to the sweet topping
- ½ cup packed light brown sugar: for the filling
- 2 tbsp all-purpose flour: thickens the juices as they bake
- 1 tsp ground cinnamon
- ¼ tsp ground nutmeg
- 1 tbsp lemon juice: brightens the apples and keeps them from browning
- Pinch kosher salt
For the crumble
- ¾ cup old-fashioned rolled oats: use old-fashioned, not instant, for a chewy, crisp texture
- ⅓ cup all-purpose flour
- ⅓ cup packed light brown sugar
- ⅓ cup cold unsalted butter, cut into small cubes: cold butter creates the crumbly topping
- Pinch kosher salt
Variations / Substitutions
- Swap the apples: any firm baking apple works well here. Honeycrisp, Braeburn, or Jonagold will hold their shape and add a different sweetness.
- Use coconut sugar: replace both brown sugars with coconut sugar for a slightly deeper, caramel-like flavor.
- Make it gluten-free: swap the flour in the filling and crumble for a good 1-to-1 gluten-free blend. Use certified gluten-free oats.
- Change up the spice: add ¼ teaspoon ground ginger or a pinch of cardamom to the filling for a warmer spice note.
- Go dairy-free: use a solid vegan butter stick in place of the butter in the crumble.

How to Make Crustless Apple Pie with Brown Sugar Crumble
Step 1: Slice and Toss the Apples
Peel the apples and cut them into ¼-inch thick slices. Toss the slices right in a large bowl with the lemon juice, then add the ½ cup brown sugar, 2 tablespoons flour, cinnamon, nutmeg, and a pinch of salt. Use your hands or a spatula to coat every piece evenly.
The slices will look glossy and coated in a sandy, fragrant spice mix. You should smell the cinnamon and a hint of the tart apples. At this stage, the sugar hasn’t released any liquid yet, so the mixture will stay loose.
Step 2: Mix the Crumble Topping
In a medium bowl, stir together the oats, ⅓ cup flour, ⅓ cup brown sugar, and a pinch of salt. Drop in the cold butter cubes and work them in with your fingertips or a pastry cutter. Keep pinching and rubbing the butter into the dry ingredients until the mixture looks like clumpy wet sand with some pea-sized pieces of butter still visible.
Those little butter clumps are what give the topping its crunchy nuggets. If the bowl feels warm at any point, pop it in the fridge for a few minutes so the butter stays cold.
Step 3: Top and Bake the Pie
Preheat your oven to 375°F. Scrape the apple mixture into a 9-inch pie dish and spread it into an even layer. Use your fingers to scatter the crumble topping all over the apples, leaving no large gaps. The apples will peek through in places, and that’s fine.
Bake for 40 to 45 minutes, until the juices are thick and bubbling around the edges and the crumble is deep golden brown. If you check with a fork, the apples should be tender and the topping should feel crisp. Let the pie sit on a wire rack after baking so the filling can settle.
Step 4: Cool and Slice the Pie
Let the pie rest for at least 20 minutes before cutting. The juices will thicken as it cools, giving you cleaner slices that hold their shape. Slice and serve warm, with a scoop of vanilla ice cream melting into the apples on the plate.
Tips for the Best Crustless Apple Pie
- Mix two types of apples for a more complex flavor. Half Granny Smith and half Honeycrisp gives you both tart and sweet with a soft texture.
- A full 30-minute rest makes the filling thick and sliceable. Cutting into it too soon leaves you with a runnier plate, which still tastes great but won’t hold a shape.
- If the crumble starts browning too fast during baking, tent the top loosely with foil for the last 10 minutes. The apples need the full time to break down even if the topping looks done early.
- Stir a handful of chopped pecans or walnuts into the crumble mixture for extra crunch. A pinch of cardamom in the topping also pairs well with the apples.
Storing Leftovers
- Refrigerate: cover the pie dish tightly and store in the fridge for up to 3 days. The topping will soften a bit overnight but still tastes wonderful.
- Reheating: warm slices in a 350°F oven for about 10 minutes to re-crisp the crumble, or microwave for 30 seconds if you want it fast.
- Serve cold: straight from the fridge, the filling is firmer and the oat topping becomes chewy, almost like a granola bar.
What to Serve with Crustless Apple Pie with Brown Sugar Crumble
Vanilla bean ice cream is the obvious choice, but a dollop of lightly sweetened mascarpone or a drizzle of warm salted caramel sauce pairs beautifully with the spiced apples. For a savory note, try a thin slice of sharp cheddar melted on top while the pie is still warm. The saltiness of the cheese cuts through the sweetness in an unexpected and cozy way.
Frequently Asked Questions
Can I use cornstarch instead of flour in the filling?
Yes. Use 1 tablespoon of cornstarch in place of the 2 tablespoons of flour. The filling will be slightly glossier and just as thick.
Can I assemble this ahead of time and bake later?
You can prepare the filling and the crumble separately, cover them, and refrigerate for up to 24 hours. Assemble and bake right before serving for the crispiest topping.
My crumble topping came out soft instead of crunchy. What went wrong?
The crumble needs cold butter and a hot oven to become crisp. If the butter softened while mixing or the oven was too low, the topping can turn cakey. Next time, chill the crumble for 10 minutes before baking and double-check your oven temperature.
Can I freeze leftover pie?
Yes. Cool the baked pie completely, wrap it tightly, and freeze for up to 2 months. Reheat slices in the oven straight from frozen at 350°F for about 15 minutes until warmed through.
