Apple Crumble Cake Recipe

I made this Apple Crumble Cake over the weekend, and my entire home smelled like a cozy autumn day. The combination of a tender, spiced vanilla cake base loaded with fresh, juicy apples and piled high with a buttery cinnamon crumble topping is absolute perfection. I love how the brown sugar streusel bakes into a thick, crunchy layer that contrasts beautifully with the soft crumb underneath.

It is warm, comforting, and wonderfully sweet without feeling overly heavy. Trust me, once you slice into this tall, streusel-packed cake and drizzle it with a little warm glaze, it will easily become your go-to fall favorite just like it did for me.

Ingredients

Using crisp baking apples and a heavy hand with the brown sugar streusel ensures every bite is packed with texture and warm cinnamon spice.

• 2 cups all-purpose flour (provides structure for a soft, tender cake crumb)
• 1 teaspoon baking powder (helps the cake layer rise evenly under the heavy crumble)
• 1/2 teaspoon baking soda (works with the sour cream to ensure a moist texture)
• 1/2 teaspoon salt (balances the rich sweetness of the sugars and glaze)
• 1 teaspoon ground cinnamon (adds warm autumn spice directly into the batter)
• 1/2 cup unsalted butter, softened to room temperature (creams smoothly for a rich cake base)
• 3/4 cup granulated sugar (adds clean sweetness to complement the apples)
• 2 large eggs, room temperature (binds the batter and adds structure)
• 1/3 cup sour cream or plain Greek yogurt, room temperature (keeps the cake ultra-moist)
• 1 teaspoon pure vanilla extract (enhances the warm, sweet bakery notes)
• 2 cups peeled and finely diced tart apples, such as Granny Smith or Honeycrisp (holds shape well during baking)
• 1 cup dark brown sugar, packed (for the thick crumble topping)
• 1 cup all-purpose flour (for the crumble structure)
• 1.5 teaspoons ground cinnamon (for the intense cinnamon crumble layer)
• 6 tablespoons unsalted butter, melted (binds the streusel into large, buttery crumbs)
• 1/2 cup powdered sugar + 1 tablespoon milk (whisked together for the optional sweet drizzle)

Note: This recipe yields 10 to 12 delicious servings.

How to Make Apple Crumble Cake?

Follow these simple, step-by-step instructions to bake a moist apple cake topped with a generous cinnamon streusel layer.

Prepare Pan and Make Crumble

Preheat your oven to 350°F (175°C) and grease a 9-inch springform pan or 9×9 baking pan, lining the bottom with parchment paper. In a medium bowl, whisk together the brown sugar, 1 cup flour, and 1.5 teaspoons cinnamon. Pour in the 6 tablespoons melted butter and mix with a fork until thick, buttery crumbs form, then set aside.

Mix the Apple Cake Batter

In a separate bowl, whisk 2 cups flour, baking powder, baking soda, salt, and 1 teaspoon cinnamon. In a large bowl, beat 1/2 cup softened butter and granulated sugar for 2 minutes until fluffy. Add the eggs, sour cream, and vanilla, beating until combined. Gently stir in the dry ingredients on low speed until just incorporated, then fold in the diced apples.

Layer and Bake

Spoon the thick apple cake batter into your prepared pan and smooth the top into an even layer. Scatter the crumble mixture evenly over the batter, pressing the crumbs lightly into the surface so they adhere. Bake for 42 to 50 minutes until a toothpick inserted into the center comes out clean. Cool in the pan for 20 minutes before transferring to a wire rack.

Glaze and Serve

While the cake finishes cooling, whisk the powdered sugar and milk together in a small bowl until smooth. Drizzle the glaze generously over the cooled crumble topping, let it set for 10 minutes, then slice and serve warm.

Additional Tips for Making this Recipe Better

Here are a few personal tricks I rely on to make sure this crumble cake turns out moist and perfectly baked every time.

• I always cut the apples into small 1/4-inch dice so they soften nicely during baking without creating large air gaps in the cake crumb.
• I highly recommend using a combination of tart apples like Granny Smith paired with sweet brown sugar so the cake isn’t overly sweet.
• I like to squeeze the crumble mixture together in my hands to create varying sizes of large and small streusel clumps for maximum texture contrast.

How to Serve Apple Crumble Cake?

Slice the cake into thick wedges or squares and place on dessert plates, highlighting the thick top layer of golden crumble and drizzled glaze. Serve it warm alongside a generous scoop of vanilla bean ice cream, a dollop of fresh whipped cream, or a warm cup of coffee or spiced chai. It makes a stunning centerpiece for autumn breakfast spreads, weekend brunches, or cozy holiday dessert tables.

Proper storage keeps the cake soft and moist while preventing the crumble topping from losing its crunch.

Storage

Store the cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days.

Freezing

You can freeze the un-glazed baked cake tightly wrapped in plastic wrap and aluminum foil for up to 2 months. Thaw overnight in the refrigerator, bring to room temperature, and drizzle with fresh glaze before serving.

Reheating

Reheat individual slices in the microwave for 10 to 15 seconds, or warm in a 300°F (150°C) oven for 5 minutes to crisp up the crumble topping again.
