This easy apple crumble recipe layers tender, cinnamon-spiced Honeycrisp apples under a thick, buttery brown sugar crumble topping, all baked right in a 9×13 dish. It’s simple enough for a weeknight, great for making ahead, and best served warm with a scoop of vanilla ice cream.
MAKE APPLE FILLING. Add apple slices, lemon juice, granulated sugar, brown sugar, cornstarch, cinnamon, and vanilla extract to a 9×13 baking dish and mix until well combined. Wipe the edges and sides of the pan with a paper towel if they get messy.
MAKE CRUMBLE. In a medium bowl, mix together 1 cup flour, 1/2 cup brown sugar, 1/3 cup granulated sugar, 1/2 teaspoon cinnamon, and 1/2 teaspoon Kosher salt. Cut 1 stick (1/2 cup) cubed butter into the dry mixture with a fork or your fingers until pea-sized clumps form and the crumble holds together when squeezed.
TOP + BAKE. Sprinkle the crumble topping over the apples in an even layer. Bake for 45-50 minutes or until the crumble is deep golden brown and the filling is bubbling at the edges.
REST. Let cool on the counter for 5-10 minutes, so the filling can thicken up before serving.
SERVE. Serve warm with a scoop of vanilla ice cream.

Notes
Honeycrisp apples are my personal favorite. They hold their shape well and their sweet-tart flavor pairs really well with the crumble topping. Granny Smith, Pink Lady, or Braeburn work great too. You can even mix and match!
Keep your slices even. Cutting everything about 1/4″ thick means all the apples cook at the same rate, so you won’t end up with some crunchy slices and some mushy ones.
Don’t skip the lemon juice. It keeps the apples from browning while you make the topping, and it adds a little brightness so the filling doesn’t taste flat.
Cold butter = clumpy crumble. Keep the butter in the fridge until you’re ready to use it. Warm butter melts into the flour and gives you a sandy topping instead of those big, crunchy clumps we all fight over.
Bake until it’s DEEP golden. It’s tempting to pull it early, but those extra few minutes are what make the topping crisp and the filling thick and jammy. Look for bubbles around the edges. That means the cornstarch has done its thing.
If the top browns too fast, loosely tent it with foil for the last 10–15 minutes.
Patience pays off. The filling looks a little runny straight out of the oven, but it thickens up as it rests. Give it those 5–10 minutes!
I love the oats in a classic apple crisp, but a crumble traditionally doesn’t have oats in it, and I sometimes prefer that!
