Apple Crumble Cake Recipe

Apple Crumble Cake Recipe tastes like a mash-up of buttery coffee cake, cozy apple pie, and crunchy bakery crumb topping in one slice. It works for busy home bakers who want a crowd-pleasing dessert in about 1 hour 10 minutes from start to finish. I baked a version of this on a Tuesday night “just to test it” and somehow three-quarters vanished before breakfast.

Why Apple Crumble Cake Recipe Is Worth It

This apple crumble cake recipe gives you soft, cinnamon-spiced apples, a tender sour-cream cake base, and a thick, crunchy crumble in every bite. It feels fancy enough for guests, but the method stays simple enough for a weeknight bake.

You mix everything in basic bowls, no mixer required, and the batter forgives small measuring mistakes. The crumble topping uses pantry staples, so you skip extra grocery runs and still get bakery-level texture.

Ingredients You Need

For the apple layer

• 3 medium apples, peeled, cored, and thinly sliced
  • Use firm apples that hold shape: Honeycrisp, Granny Smith, Pink Lady, or Fuji.
• 2 tbsp granulated sugar
• 1 tsp ground cinnamon
• 1 tsp lemon juice (bottled works in a pinch)
• 1 tsp cornstarch or all-purpose flour (helps thicken juices)

For the crumble topping

• 1 cup all-purpose flour
• ½ cup packed light brown sugar
• ¼ cup granulated sugar
• 1 tsp ground cinnamon
• ¼ tsp fine sea salt
• ½ cup (1 stick) unsalted butter, melted and slightly cooled
  • Use salted butter if needed and reduce added salt to a pinch.

For the cake batter

• 1½ cups all-purpose flour
• 1½ tsp baking powder
• ¼ tsp baking soda
• ½ tsp fine sea salt
• ½ cup (1 stick) unsalted butter, softened
• ¾ cup granulated sugar
• 2 large eggs, room temperature
• 1½ tsp pure vanilla extract (I like Nielsen-Massey or Costco’s vanilla)
• ½ cup sour cream or plain Greek yogurt, room temperature
• ¼ cup milk (whole or 2% works best)

Optional finishing touches

• Powdered sugar, for dusting
• Caramel sauce, for drizzling
• Vanilla ice cream or whipped cream, for serving

Pantry shortcuts and substitutions

• Use pre-sliced bagged apples if you feel short on time; just slice them thinner.
• Swap half the white flour in the crumble with quick oats for a heartier texture.
• Use brown sugar only in the crumble if you run out of white sugar; the topping turns extra caramel-like.
• Use yogurt instead of sour cream if that sits in your fridge more often.

Equipment list

• 8-inch or 9-inch square baking pan (or a 9-inch springform pan)
• Parchment paper
• Two medium mixing bowls and one large mixing bowl
• Whisk and rubber spatula
• Measuring cups and spoons
• Knife and cutting board
• Small saucepan or microwave-safe bowl to melt butter
• Toothpick or cake tester

Quick Tips & substitutions

• Line the pan with parchment and leave overhang so you lift the cake out easily and slice clean squares.
• Slice apples thinly and evenly so they soften at the same rate and nestle into the cake.
• Use room-temperature eggs, butter, and sour cream so the batter mixes smoothly and bakes evenly.
• Stir the crumble until it forms big, clumpy bits; squeeze it with your hands if it looks too sandy.
• If the crumble looks dry, drizzle in 1–2 teaspoons melted butter and toss again.
• If the top browns too quickly, tent the pan loosely with foil during the last 10–15 minutes.
• Swap sour cream with full-fat Greek yogurt in equal amounts.
• Use a gluten-free 1:1 baking flour blend for both cake and crumble if you need a gluten-free version.
• Replace butter with vegan butter sticks and sour cream with thick dairy-free yogurt for a dairy-free twist.
• Add a pinch more salt if you use very sweet apples to keep the flavor balanced.

How to Make Apple Crumble Cake Recipe

Step 1: Prep the pan and oven

Preheat your oven to 350°F (175°C). Grease an 8-inch or 9-inch square pan, then line it with parchment, leaving a little overhang on two sides. This setup makes removal and slicing much easier.

Step 2: Mix the apple layer

Add sliced apples, sugar, cinnamon, lemon juice, and cornstarch to a bowl. Toss until the slices look evenly coated and glossy. Set the bowl aside while you mix the cake and crumble so the flavors meld.

Step 3: Stir together the crumble topping

In a medium bowl, whisk flour, brown sugar, granulated sugar, cinnamon, and salt. Pour in melted butter and stir until the mixture forms moist clumps and some larger chunks. If it looks too wet and pasty, sprinkle in 1–2 extra tablespoons flour and toss again.

Step 4: Whisk the dry ingredients for the cake

In another medium bowl, whisk flour, baking powder, baking soda, and salt. This step spreads the leavening evenly so the cake rises nicely. Set the bowl aside.

Step 5: Cream butter and sugar

In a large bowl, beat softened butter and sugar with a whisk or hand mixer until the mixture looks light and fluffy. Scrape down the sides so no butter hides at the bottom. This step gives the cake a tender, soft crumb.

Step 6: Add eggs and vanilla

Beat in the eggs one at a time, mixing until the batter looks smooth after each addition. Stir in vanilla extract. The batter may look slightly thick, and that texture works perfectly.

Step 7: Add dry ingredients and dairy

Stir the sour cream into the butter mixture until combined. Add half the dry ingredients, then the milk, then the remaining dry ingredients, stirring gently after each addition. Mix just until no dry streaks remain so the cake stays tender and fluffy.

Step 8: Assemble the layers

Spread the cake batter evenly into the prepared pan; use a spatula to nudge it into the corners. Arrange the apple slices over the batter in an even layer, slightly overlapping them. Sprinkle the crumble topping over the apples, breaking up any very large chunks so the top bakes evenly.

Step 9: Bake the apple crumble cake

Place the pan on the middle rack and bake 40–50 minutes, depending on pan size and oven. Start checking at 38 minutes and insert a toothpick into the center; it should come out with a few moist crumbs but no wet batter. If the top browns too quickly before the center sets, tent the pan with foil and keep baking until the cake tests done.

Step 10: Cool, slice, and serve

Set the pan on a wire rack and let the cake cool at least 20–30 minutes. Use the parchment overhang to lift the cake out if you want clean squares, or slice directly in the pan if patience runs low. Dust with powdered sugar or drizzle caramel sauce over the top, then serve warm or at room temperature.

Recipe Variations

• Gluten-free: Use a 1:1 gluten-free baking flour for both cake and crumble, and check that your cornstarch and baking powder list gluten-free on the label.
• Vegan: Use vegan butter sticks, dairy-free yogurt instead of sour cream, and a neutral plant milk; swap each egg with ¼ cup unsweetened applesauce or a flax egg.
• Low sugar: Cut the sugar in the cake and crumble by 25–30%; the apples still bring sweetness.
• Low carb-ish: Use a low-carb sweetener that measures like sugar and almond flour for part of the crumble, while you keep the cake flour-based for structure.
• Extra spice: Add nutmeg, allspice, or cardamom to the apples and crumble for a warm bakery flavor.
• Oat crumble: Replace ½ cup of the crumble flour with rolled oats for a more rustic texture.
• Nutty crunch: Stir ½ cup chopped pecans or walnuts into the crumble.
• Caramel apple: Swirl ¼ cup thick caramel sauce over the apples before you add the crumble.
• Apple chunk cake: Dice the apples and fold half into the batter, then scatter the rest on top under the crumble.

Ways to Serve Apple Crumble Cake Recipe

• Serve warm with a scoop of vanilla ice cream.
• Add a dollop of whipped cream and a sprinkle of cinnamon.
• Pack slices in lunchboxes as a fun dessert treat.
• Enjoy a square with hot coffee or tea for a cozy afternoon snack.
• Top with a drizzle of warm caramel sauce and a pinch of flaky salt.

Storage Success

Let the apple crumble cake cool completely, then cover the pan tightly or transfer slices to an airtight container. Store at room temperature for up to 2 days, or refrigerate for up to 5 days if your kitchen runs warm. Reheat slices in the microwave for 15–20 seconds or in a 300°F oven for about 8–10 minutes so the crumble crisps again. Freeze individual wrapped slices for up to 2 months, then thaw at room temperature and warm before serving.
