I’ve published a plethora of crumb cake/coffee cake/breakfast cake recipes on my website. One of my forever favorites has been (and will always be!) my apple crumb cake. Usually prepared a few times during the fall months, this tall towering beauty is buttery, moist, and absolutely LOADED with a soft crumb topping. Readers have loved this breakfast cake too.
When I asked bakers for their opinion on what makes crumb cake “New York style”, most said the description means extra crumb topping with a soft and buttery tight-crumbed (but not dense) cake underneath. Today’s recipe checks all those boxes. Some highlights:
It’s perfect.
This is a butter and sour cream based cake, so you already know it’s going to be flavorful, tender, and moist. The ingredients in the cake and crumb topping are mostly the same, which is extra convenient– especially since you’re likely making this before you’ve had your morning coffee. Good morning!
Now it’s time to chat about that luxurious crumb topping. Have you ever had crunchy streusel topping before? It’s good, but not quite what I’m delivering to you today. This crumb topping is thick and soft, as long as it’s not over-mixed or over-baked. Think of it like soft cookie crumbles on top of your breakfast cake. YES!
Cake for breakfast is always a good idea. This crumb layer is half of the entire cake and I haven’t heard any complaints about that! Nothing short of a dream.

Description
This is my favorite recipe for classic New York-style crumb cake. The cake is buttery and moist and you’ll definitely enjoy the thick crumb topping!
Ingredients
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 (2 sticks; 230g) unsalted butter, melted
- 2 and 1/2 cups (310g) all purpose flour, spoon & leveled
Cake
- 2 and 1/2 cups (310g) all purpose flour, spoon & leveled
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 3/4 cup (1.5 sticks; 170g) unsalted butter, softened to room temperature
- 1 cup (200g) granulated sugar
- 3 large eggs, at room temperature
- 1 cup (240g) full-fat sour cream, at room temperature*
- 2 teaspoons pure vanilla extract
- optional: confectioners’ sugar for topping
Instructions
- Preheat the oven to 350°F (177°C) and grease a 9×13 inch baking pan or line with parchment paper. You can use a glass, ceramic, or metal baking pan. The bake time is similar for each, but use a toothpick to test for doneness. Metal baking pans cook cakes faster. Set pan aside.
- Make the crumb topping: Mix the brown sugar, granulated sugar, cinnamon, and salt together in a medium bowl. Stir in the melted butter, then gently mix the flour using a fork. Keep the mixture as large crumbles, do not over-mix. If over-mixed, this will turn into a thick paste. Set aside.
- 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 smooth and creamy, about 2 minutes. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. Add the eggs, sour cream, and the vanilla. Beat on medium-high speed until combined. The mixture may 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 over-mix. The batter will be thick, creamy, and sticky.
- Spread the batter evenly into prepared baking pan. Top with crumb topping. Using a rubber 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 wire rack. Allow to slightly cool for at least 30-45 minutes before cutting. If desired, dust with confectioners’ sugar before slicing and serving. Use a sifter/fine mesh sieve.
Notes
- Make Ahead Instructions: Prepare cake through step 7. 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.
- 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. I don’t recommend removing fat from this cake by using a lower fat yogurt or sour cream alternative.
- Room Temperature: All refrigerated items should be at room temperature so the batter mixes together easily and evenly. Read here for more information.
