Ultra soft apple crumb cake is loaded with warm cinnamon apples and extra crumb topping. A homemade version of classic New York-style crumb cake, this breakfast cake is buttery and moist, deliciously tender, and drizzled with sweet maple icing.
I originally published this recipe in 2017 and have since added new photos and more success tips.
If crumb topping is your love language, you’ve come to the right place. And if warm cinnamon apples make your mouth water, today’s your day. Finally, if soft buttery cake is your ideal indulgence, I’m your baker.
Today’s homemade apple crumb cake is like my apple cinnamon crumb muffins, apple cake, and apple cinnamon bread… but in breakfast/coffee cake form. Those are favorite seasonal recipes to make (along with pumpkin crumb cake muffins), so a cake version is a no-brainer. Readers have loved it:
One reader, Jean, commented: “One of the best crumb cakes I have ever made. The crumb topping adhered beautifully and made the cake. I also like the addition of sour cream to the cake which helped to make the cake moist, not dry like so many crumb cakes. ★★★★★“
One reader, Les, commented: “There is no other word to describe this cake than PERFECT! Tried many recipes from your site and this one is now in our top 3 best cakes… ★★★★★“
One reader, Martha, commented: “There are not enough superlatives to adequately describe this cake. Perfection. This is a keeper recipe. ★★★★★“
One reader, Sarah, commented: “THIS CAKE DESERVES WAY MORE THAN 5 STARS. Absolutely marvelous recipe… this will forever be my ‘go-to’ coffee cake recipe… the crumb topping is delightfully crunchy and is easily the best streusel I have ever had. ★★★★★“
Ingredients You Need & Why
Like my traditional coffee cake recipe, this is a butter- and sour cream-based cake, AKA the best kind of cake, and here’s what you need to make it:
- Flour: All-purpose flour provides the structure of this cake. It’s sturdy enough to support the thick batter and multiple layers of this crumb cake.
- Baking Soda + Baking Powder: Baking soda and baking powder help the cake rise.
- Sugar: Granulated sugar sweetens the cake, and you need brown sugar for the crumb topping.
- Butter: Butter adds flavor and creates structure in the creaming process.
- Sour Cream: Sour cream gives us an extremely moist crumb cake that’s a little denser than, say, a fluffy vanilla cake. Tight crumbs, like pound cake, but with a much softer texture. Don’t remove the fat from this cake by using a lower-fat alternative. Fat = flavor! We don’t want to skimp there. This is cake!
- Eggs: 3 eggs add richness and bind the ingredients together.
- Salt + Vanilla Extract: Use both for flavor.
- Cinnamon: We can’t have crumb cake without cinnamon!
- Apples: The star of apple crumb cake, of course.
Best Apples for This Cake
Use any variety of apples you enjoy! You need about 2 medium-size apples for this recipe. Personally, I love tart Granny Smith apples paired with the sweet crumb cake. If you enjoy a certain type of apple in your apple pie or apple cinnamon scones, you’ll love it here, too.
- Tart apples I love: Granny Smith, Braeburn, Jonathan, and Pacific Rose
- Sweet apples I love: Jazz, Honeycrisp, Pink Lady, Gala, and Fuji
And here’s a full list of the best apples for baking.
Overview: How to Make Apple Crumb Cake
When I first tested this recipe, I mixed the apples into the cake batter (just like we do in my apple cinnamon muffins recipe). This was tasty, of course, but the pieces of apples each held a soggy outline inside the baked cake. It just… didn’t look appetizing. I found that layering the apples on top of the cake batter was best.
This gives us 3 delectable layers: a soft and buttery cake, topped with tender cinnamon-spiced apples, and then a TRUCK LOAD of crumb topping.
This apple crumb cake comes together easily.
Make the crumb topping first. Place that in the refrigerator or freezer until you need it. The colder the crumbs, the more they will hold shape in the oven.
Whisk the dry ingredients together and set aside. In a separate bowl, cream the butter and sugar until light and fluffy. Beat in the eggs, sour cream, and vanilla until combined—the mixture may look curdled, and that’s perfectly fine. Gently mix the wet and dry ingredients together.
Toss the apple chunks with cinnamon, then spread the thick batter into a 9×13-inch pan (this size is just right for the amount of batter). Scatter the apples and crumb topping evenly over the batter, pressing the crumbs down firmly so they stick.
Bake until golden and set. If the top or edges begin browning too quickly, loosely cover the pan with aluminum foil to prevent over-baking.
Crumb Cake with Extra Crumbs
You’ll notice A LOT of ingredients in the crumb topping. Not in the number of ingredients, but in terms of the volume of ingredients… like more butter, sugar, and just as much flour as in the cake itself. Why? Because the crumb topping is the BEST PART of a CRUMB CAKE!
You’re using the same ingredients in the crumb topping as you are in the cake, so it’s an extremely convenient recipe. The gang’s all here: granulated sugar, cinnamon, salt, melted butter, and flour, plus brown sugar. Make sure some crumbles stay in larger chunks because those are the best bites.
The crumb layer is literally half the cake and I see zero problem with this! Otherwise, you might as well just make a regular apple cake (also delicious, by the way)!
Icing Options
This apple crumb cake truly doesn’t need anything on top, but if the opportunity for sweet maple icing presents itself, we’d be fools to say no. Here are some wonderful icing options for this cake:

Description
Delicious New York-style crumb cake with warm cinnamon apples and DOUBLE the buttery crumb topping! Make the crumb topping first, and then place it in the refrigerator or freezer until ready to use. Cold crumbs hold their shape in the oven.
Crumb Topping
- 1 cup (200g) packed light or dark brown sugar
- 1/2 cup (100g) granulated sugar
- 1 Tablespoon ground cinnamon
- 1/2 teaspoon salt
- 1 cup (16 Tbsp; 226g) unsalted butter, melted
- 2 and 1/2 cups (313g) all purpose flour (spooned & leveled)
Cake
- 2 and 1/2 cups (313g) all purpose flour (spooned & leveled)
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 3/4 cup (12 Tbsp; 170g) unsalted butter, softened to room temperature
- 1 and 1/4 cups (250g) granulated sugar
- 3 large eggs, at room temperature
- 1 cup (240g) full-fat sour cream, at room temperature*
- 2 teaspoons pure vanilla extract
- 2 and 1/2 cups (310g) peeled chopped apples (about 2–3 apples, see Note)
- 1/4 teaspoon ground cinnamon
- optional: maple icing, vanilla icing, or caramel icing from apple cinnamon rolls
- Preheat the oven to 350°F (177°C) and grease a 9×13-inch baking pan or line with parchment paper. Set aside.
- Make the crumb topping: Mix the brown sugar, granulated sugar, cinnamon, and salt together in a medium bowl. Stir in the melted butter. Using a fork, lightly mix in the flour until crumbles form. Don’t over-mix. Place in the refrigerator or freezer until you need it in step 6. Cold crumbs hold their shape in the oven.
- Make the cake: Whisk the flour, baking soda, baking powder, and salt together. Set aside.
- Using a handheld or stand mixer fitted with a paddle attachment, beat the butter and granulated sugar together on high speed until light and creamy, about 3 minutes. Scrape down the sides and up the bottom of the bowl with a silicone spatula as needed. Add the eggs, sour cream, and the vanilla. Beat on medium-high speed until combined. The mixture will look curdled; that’s ok. Scrape down the sides and up the bottom of the bowl as needed. With the mixer on low speed, mix in the dry ingredients until smooth. Do not overmix. The batter will be thick.
- Toss the chopped apples and cinnamon together.
- Spread the batter evenly into prepared baking pan. Top evenly with cinnamon-coated apples. Top with crumb topping. Using a silicone spatula or the back of a large spoon, press the crumb topping tightly down into the cake so it sticks.
- Bake for 45-55 minutes. Baking times vary, so keep an eye on yours. The cake is done when a toothpick inserted in the center comes out clean. If you find the top or edges of the cake is/are browning too quickly in the oven, loosely cover it with aluminum foil.
- Remove the cake from the oven and set on a cooling rack. Allow to slightly cool for at least 30-45 minutes before slicing and serving.
- Drizzle with optional icing, if desired.
- Cover leftover cake tightly and store in the refrigerator for 5 days.
Notes
- Freezing Instructions: Prepare cake through step 8. Cover the cake tightly and refrigerate for up to 2 days or freeze up to 3 months. Bring to room temperature, add icing if desired, and serve.
- Special Tools (affiliate links): 9×13-inch Baking Pan | Glass Mixing Bowls | Apple Peeler | Whisk | Electric Mixer (Handheld or Stand) | Silicone Spatula | Cooling Rack
- Sour Cream: Sour cream is a key ingredient in this cake. I don’t suggest subbing the sour cream with a liquid—plain full-fat yogurt would work though. But don’t remove the fat from this cake by using a lower fat yogurt or sour cream alternative.
- Apples: For depth of flavor, it’s best to bake with a mix of sweet and tart apples. For this cake, I usually use about 1 large Honeycrisp apples and 1 large Granny Smith apple. For slicing, it’s best to chop the apple into thin pieces. Slice the apple, then cut each of those slices in half so you have smaller, thinner, easy-to-eat pieces. See photo above.
- Room Temperature: All refrigerated items should be at room temperature so the batter mixes together easily and evenly. Read more about the importance of room temperature ingredients.
