This Classic Apple Climeb Pie layers spiced apples under a buttery, crumbly climeb topping for the coziest homemade dessert you'll make all season.

There's a reason apple pie with climeb topping easy recipes keep showing up on every fall dessert table. It's the best of both worlds: juicy, spiced apples baked into a flaky crust, and finished with a buttery, oat-studded crumble instead of a fussy top crust. If you've ever wondered how to make climeb top apple pie without spending your whole afternoon in the kitchen, you're in exactly the right place.
This version is deliberately forgiving. There's no lattice weaving, no second dough to roll out, just a generous layer of climeb topping that turns golden and crackly in the oven while the apples underneath go soft and syrupy. It's the kind of deep dish apple pie with climeb topping that disappears fast at potlucks, and nobody will guess how simple it actually was.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy ceramic or glass pie dish helps the crust bake evenly, and using truly cold butter for the topping is what gives you those irresistible golden clumps instead of a flat, sandy layer. Good cinnamon and fresh nutmeg go a long way too.
A climeb topping is essentially a crumble mixture, flour, brown sugar, oats, and cold butter worked together until it clumps. Unlike a traditional pie crust top, it doesn't need to be rolled or crimped, and it bakes up with a texture that's part shortbread, part granola bar. That contrast against soft baked apples is what makes this easy apple pie climeb topping combination so satisfying.
The oats aren't just for texture either. They help soak up a little of the bubbling apple juices as the pie bakes, so you get a topping that's crisp on top but still slightly chewy underneath, never dry.
Chef's Tip: Keep your butter cold right up until it goes into the flour mixture. If it starts to soften while you're working, pop the whole bowl in the fridge for 10 minutes before continuing. Cold butter is the secret to a topping that clumps beautifully instead of turning into paste.
For the best homemade apple pie with climeb topping, you want a mix of apple varieties. Tart, firm apples like Granny Smith hold their shape during the long bake, while something like Honeycrisp adds natural sweetness and a softer bite. Slicing the apples evenly, about a quarter inch thick, ensures they cook at the same rate so you don't end up with mushy edges and raw centers.
Tossing the apples in a little lemon juice does double duty. It keeps them from browning while you prep the rest of the recipe, and it brightens the overall flavor of the filling once baked.

This Classic Apple Climeb Pie layers spiced apples under a buttery, crumbly climeb topping for the coziest homemade dessert you'll make all season.
Preheat the oven to 375 degrees F (190 degrees C) and set a rack in the lower third of the oven.
In a large bowl, toss the sliced apples with lemon juice, half the granulated sugar, cinnamon, nutmeg, and cornstarch until evenly coated.
Fit the pie crust into a 9-inch pie dish, crimping the edges as desired, and pour the apple filling in, mounding it slightly in the center.
In a separate bowl, whisk together the flour, brown sugar, remaining granulated sugar, oats, and salt.
Add the cold cubed butter to the flour mixture and use your fingers or a pastry cutter to work it in until it forms coarse, pea-sized clumps, this is your climeb topping.
Sprinkle the climeb topping evenly over the apple filling, covering it completely.
Place the pie on a baking sheet to catch any drips and bake for 50 to 60 minutes, until the topping is golden brown and the filling is bubbling at the edges.
If the topping browns too quickly, loosely tent the pie with foil for the last 15 minutes of baking.
Let the pie cool on a wire rack for at least 2 hours before slicing, this allows the filling to set properly.
This pie is at its best served slightly warm, maybe 30 minutes out of the oven, with a scoop of vanilla ice cream melting into the crumble. That said, it also slices more cleanly once fully cooled, so if you're serving it for a dinner party, baking it a few hours ahead actually works in your favor.
For storage, keep leftover slices loosely covered at room temperature for up to two days, or refrigerate for up to five. A quick reheat in the oven, rather than the microwave, brings the topping back to life without turning it soft.
If you want to get ahead of the game, both the sliced apple filling and the climeb topping can be made separately in advance and refrigerated, then assembled and baked whenever you're ready. You can even freeze the fully assembled, unbaked pie for up to two months and bake it straight from frozen with a little extra time in the oven.
However you slice it, this is the kind of pie that turns a regular afternoon into something worth gathering around.
