Apple Pie Crumble Cake Recipe: Buttery Streusel Crown With Spiced Apple Filling

This apple pie crumble cake recipe delivers all the comfort of classic apple pie with the convenience of a single-layer dessert.

The secret lies in a perfectly spiced apple filling—tender, juicy slices of peeled apples simmered with cinnamon, brown sugar, and just a touch of lemon—all topped with a buttery, oat-studded crumble that turns golden and crispy in the oven.

I developed this recipe after years of baking apple desserts, and it’s the one that finally convinced even my most skeptical friends to skip the pie crust entirely.

The beauty of this dessert is its balance: the filling stays moist and flavorful while the crumble topping achieves that ideal mix of crunchy and caramelized edges.

You can use store-bought crumble mix for a shortcut, but I recommend making it from scratch—just mix flour, butter, sugar, and oats until it resembles coarse sand. The result is a texture that’s crispy enough to cut through the soft apples but tender enough to melt slightly with each bite.

Baking at 375°F for about 45 minutes ensures a bubbling filling and a crumble topping that’s golden and fragrant. The aroma alone will have everyone gathering in the kitchen, and the first slice reveals layers of warm spiced apples, sweet caramelized crumble, and that perfect contrast of textures.

Serve it warm with a scoop of vanilla ice cream or a drizzle of caramel for an extra touch of indulgence.

This recipe is equally at home at a family dinner or a holiday gathering—it’s simple enough for weeknights but impressive enough for special occasions. The best part? It’s foolproof, with clear steps for peeling, slicing, and assembling, so even beginners can achieve restaurant-quality results. Let’s get baking!

Ingredients for apple pie crumble cake

The perfect mix of juicy spiced apples and buttery crumble—no crust needed.

The apples are the star. Granny Smith and Honeycrisp give you that perfect balance of tart and sweet—Trader Joe's or Whole Foods usually have pre-washed bags. If you're using store-bought, peel and slice them all at once—they brown fast. For the filling, I always grab Bob's Red Mill cinnamon because it's fresh-ground, but regular grocery store stuff works too. The brown sugar? Light or dark doesn't matter here, but packed means more caramel flavor. Pro tip: toss the sliced apples with lemon juice right away to keep them bright.

No Granny Smith? Fuji or Gala apples work great—just add an extra tablespoon of lemon juice. Short on oats? Quick oats blended into flour works in a pinch, but they won't be as crispy. The vanilla extract is where you can splurge—Nielsen-Massey is my go-to, but imitation will do. For the crumble, cold butter is key. Cut it into small cubes and toss with the dry ingredients until it looks like coarse sand. That's what gives you those perfect golden chunks. Want to make it ahead? The crumble mix can be prepped and refrigerated for up to 3 days—just toss it with the apples right before baking.

This dessert tastes even better the next day—cover loosely and refrigerate if you're not serving it warm. Reheats beautifully in a 350°F oven for 10 minutes with a splash of water in the pan. I always make a double batch because it disappears fast. Store leftovers in an airtight container for up to 5 days. Freezes well too—just wrap individual slices in plastic wrap. The crumble gets even more amazing after freezing and reheating, so it's perfect for meal prep.

Step-by-step instructions for apple pie crumble cake

Here's how to build this showstopper—layered apple filling meets buttery crumble crown.

In a large bowl, combine the peeled and sliced apples with the 1.5 cups granulated sugar, 0.5 cup light brown sugar, 0.5 cup all-purpose flour, 2 teaspoons ground cinnamon, and 0.5 teaspoon salt. Toss everything together until the apples are evenly coated. The sugar should cling to each slice, creating a sweet, spiced base.

Transfer the mixture to a 9-inch pie dish and spread it out evenly. Drizzle the 2 tablespoons lemon juice over the top—this brightens the apples and prevents browning. The filling should look glossy and inviting, with no dry spots. Let it sit at room temperature while you prepare the crumble topping.

In a medium bowl, cut the 0.75 cup cold unsalted butter into small cubes. Use a pastry cutter or your fingers to work it into the 1 cup old-fashioned rolled oats until the mixture resembles coarse crumbs. Add the 0.75 cup all-purpose flour and 0.5 cup granulated sugar, then mix gently with a fork—just until combined. You want a texture that holds together when pressed but still has visible oat pieces.

Sprinkle the streusel evenly over the apple filling, pressing down lightly with your fingers. The topping should cover the filling completely, with no gaps. This is where the magic happens—the crumble will bake into a golden, crispy crown while keeping the apples tender underneath.

Preheat your oven to 375°F. Place the pie dish on a baking sheet lined with parchment paper—this prevents any potential mess. Bake for 40-45 minutes, until the edges of the crumble are deep golden brown and the filling is bubbling around the edges. The center should still feel slightly soft when pressed gently with a finger—it will continue cooking as it cools.

I like to check at the 35-minute mark because ovens vary. If the top is browning too quickly, tent it loosely with foil to prevent burning while still allowing the filling to cook through. The cake is done when the crumble is crispy and the apples are tender but not mushy.

Remove the cake from the oven and let it cool for 10 minutes before serving. This resting time lets the juices settle, ensuring each bite is moist and flavorful. The crumble will firm up slightly as it cools, giving it that perfect texture—crispy on top, tender underneath.

Serve warm with 2 cups vanilla ice cream on the side. The contrast of warm spiced apples and cool vanilla is unbeatable. For extra flair, sprinkle a pinch of cinnamon on top right before serving—it adds a fresh burst of aroma that makes every bite feel special.

Dietary considerations for this apple pie crumble cake

Gluten-Free Adaptations

For a gluten-free version, swap the all-purpose flour in both the filling and crumble with a 1:1 gluten-free baking flour blend like Bob's Red Mill 1-to-1 or King Arthur Measure for Measure.

Use the same measurements—just ensure your blend contains xanthan gum for proper texture. The crumble will still achieve that crispy golden finish, though it may be slightly less sturdy. 🥣

Dairy-Free Options

Replace the butter in the crumble with cold dairy-free butter (like Miyoko's or Earth Balance) or coconut oil for a vegan twist. The coconut oil adds a subtle tropical note that pairs surprisingly well with the spiced apples.

For extra richness, use ½ cup dairy-free butter + ¼ cup coconut oil to mimic the texture. The filling remains unchanged since it doesn’t contain dairy.

Lower-Sugar Versions

Reduce the sugar in the filling by ¼ cup (use 1.25 cups granulated sugar total) and replace the remaining ¼ cup with unsweetened applesauce or mashed banana. In the crumble, cut the sugar to ¼ cup and add 1 teaspoon vanilla extract to enhance flavor.

The apples' natural sweetness will shine through, and the crumble stays delicious without being overly sweet.

Nut-Free Crumble

Skip the rolled oats entirely and replace them with 1 cup crushed cornflakes or 1 cup shredded coconut for a nut-free crumble. For extra crunch, add ½ cup chopped pecans (if nuts are allowed) or ½ cup toasted pumpkin seeds.

The cornflakes create a crispy, golden texture that mimics the oats perfectly while keeping the dish safe for nut allergies. 🌰

Allergen-Friendly Substitutions

For egg-free baking, no changes are needed—the recipe doesn’t require eggs. If you’re avoiding citrus, reduce the lemon juice to 1 tablespoon and add ½ teaspoon extra cinnamon to compensate.

For a soy-free option, ensure your vanilla extract is soy-free (like Nielsen-Massey Pure Vanilla), and check your butter or dairy-free alternative for soy additives.
