What Ingredients are in Rustic Apple Crumble Tart?
This delicious rustic apple crumble tart combines three essential components: a buttery almond crust, juicy spiced apple filling, and a crunchy oat crumble topping.
For the tart dough:
- 1 cup all-purpose flour
- ½ cup almond flour
- ⅔ cup powdered sugar
- 5 tablespoons cornstarch
- ¼ teaspoon kosher salt
- 1½ teaspoons vanilla extract
- 10 tablespoons room temperature butter

For the apple filling:

- 2 tablespoons ground cinnamon
- 1 teaspoon ground nutmeg
- Cornstarch (for thickening)
- Kosher salt
- Vanilla extract
For the crumble topping:
- 1¾ cups all-purpose flour
- ⅓ cup quick oats
- Brown sugar (from filling ingredients)
- Cinnamon (from filling ingredients)
- ½ teaspoon kosher salt

When shopping for this recipe, green apples like Granny Smith work best as their tartness balances the sweetness of the sugar, but feel free to mix in other varieties like Honeycrisp or Pink Lady if you prefer a more complex flavor profile.
How to Make this Rustic Apple Crumble Tart
Making this gorgeous apple crumble tart is easier than it looks—promise! Start by preparing the buttery tart dough. In a mixing bowl, combine 1 cup all-purpose flour, ½ cup almond flour, ⅔ cup powdered sugar, 5 tablespoons cornstarch, and ¼ teaspoon kosher salt. Add 1½ teaspoons vanilla extract, 10 tablespoons of room temperature butter, and 1 large egg, mixing until you have a soft, pliable dough. Press this mixture evenly into your tart pan, making sure to work it up the sides. The almond flour gives the crust a wonderful nutty dimension that perfectly complements the apples.
For the filling, peel and dice 6-7 medium green apples (seriously, don’t skip the peeling—nobody wants tough apple skin in their elegant tart). Toss these apple pieces with 3 tablespoons lemon juice to prevent browning, then mix in 1 cup packed brown sugar, 2 tablespoons ground cinnamon, and 1 teaspoon ground nutmeg. Who doesn’t love that warm spice aroma filling the kitchen? Add a bit of cornstarch to thicken the juices, a pinch of kosher salt, and a splash of vanilla extract. Spread this mixture evenly in your prepared tart shell.
Now for the crowning glory—the crumble topping. Combine 1¾ cups all-purpose flour, ⅓ cup quick oats, some of your brown sugar and cinnamon mixture, ½ teaspoon kosher salt, ¾ cup melted unsalted butter, and ½ teaspoon vanilla extract. This will form a beautifully textured topping that gets wonderfully crunchy when baked. For even more consistently mixed ingredients, consider using a premium stand mixer to perfectly blend your crumble components.
Bake your masterpiece at 350°F for about 40-50 minutes, until the top is golden brown and the filling is bubbling around the edges. If you notice the edges browning too quickly, just tent them with some aluminum foil—a little baker’s trick that works wonders. The most challenging part? Letting it cool before slicing. Trust me, this allows the filling to set properly and prevents a runny mess. The wait is worth it when you bite into those perfectly cooked apple chunks nestled in that buttery, almondy crust, all topped with that irresistible crumble. Heaven on a plate, really.
What to Serve with Rustic Apple Crumble Tart
Now that you’ve crafted this stunning apple tart, let’s talk about what to serve alongside it to create a truly memorable dessert experience. My favorite pairing is a scoop of vanilla bean ice cream, slowly melting into those warm apple crevices. Divine.
For something different, try salted caramel sauce drizzled on top, or a dollop of cinnamon whipped cream. Want to balance the sweetness? A slice of sharp cheddar cheese works surprisingly well.
For drinks, consider hot apple cider, coffee, or even a dessert wine like Sauternes. Isn’t it amazing how the right accompaniment can transform a simple tart?
Leftovers and Storage for this Rustic Apple Crumble Tart
While you mightn’t have any leftovers after serving this irresistible tart, sometimes our eyes are bigger than our stomachs, and you’ll need to store the remaining slices.
I recommend keeping your apple crumble tart in an airtight container in the fridge for up to 3 days. Want to enjoy it warm again? Just pop a slice in the microwave for 20-30 seconds, or reheat in a 300°F oven for about 10 minutes. The texture might change slightly, but the flavor stays divine.
Freezing works too! Wrap individual slices tightly in plastic, then foil. They’ll keep for about 2 months. Thaw overnight in the fridge.
Rustic Apple Crumble Tart Substitutions and Variations
Even though this apple crumble tart recipe is perfect as written, you’ll be happy to know it’s incredibly adaptable to whatever ingredients you might’ve on hand.
Swap green apples for Honeycrisp or Gala if you prefer sweeter flavor, or mix in pears for a delightful twist. No almond flour? Simply use all-purpose throughout. Gluten-free? Replace regular flour with a cup-for-cup alternative.
The crumble topping welcomes modifications too – try pecans or walnuts for extra crunch, or replace some oats with coconut flakes. Can’t do dairy? Coconut oil works beautifully instead of butter.
Final Thoughts
