This Pumpkin Crumb Cake has a thick layer of crumble topping over a softly spiced, moist pumpkin cake. This is one of my personal favorite cakes!

Happy October! Now that’s officially pumpkin month, I had to share a pumpkin recipe – one that’s loaded with spices and warmth and goodness and pecans and LOTS of crumbles. This pumpkin crumb cake does just that ^^.
Also, when I first made this, I called it a coffee cake. Then I thought, well that has a whole lot of crumbs…maybe it’s a crumb cake. Then I realized I had absolutely nooo idea what the difference between a crumb cake and a coffee cake was. So, I asked Google, and found some answers.
1. Coffee cakes can be pretty much anything that you would want to serve with coffee.
2. People from NY/NJ believe a crumb cake should have at least a 1:1 crumb to cake ratio.
3. A crumb cake can be a coffee cake, but a coffee cake is not always a crumb cake.
4. Crumb cake ALWAYS has a whole lot of crumbles on top.
Phew – got that? I think most of us (or at least me…) have a certain image of coffee cake, probably something with crumbles andcinnamon and maybe a swirl through it. But it can be anything! Crumb cakes, though, are specific. You can’t just call anything a crumb cake.
So…this pumpkin cake I got here? I’m calling it a crumb cake, because guys, that is a THICK crumb layer. I’m all about a good crumb topping, so I made this one thick, crunchy, and exactly what you want out of your crumble layer.
I also added pecans, because I <3 them, but you can replace them with your favorite nut or just leave ’em out entirely.
This pumpkin crumb cake also is sooo perfect for fall, because hello: pumpkin and cinnamon. I know you’re being bombarded with pumpkin recipes all over the internet, but I truly believe this one is special. Take that for what you will.
Happy October! Enjoy :)

Pumpkin Crumb Cake
Ingredients
For the cake
- 1 1/2 cups all-purpose flour
- 2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 2 teaspoons ground cinnamon
- 1/4 teaspoon freshly grated nutmeg
- 1/2 teaspoon kosher salt
- 1/2 cup 1 stick unsalted butter
- 1 cup light brown sugar
- 2 eggs
- 2/3 cup pumpkin puree
- 1/3 cup sour cream
For the crumb topping
- 1/3 cup granulated sugar
- 1/3 cup dark brown sugar
- 3/4 teaspoon ground cinnamon
- 1/8 teaspoon table salt
- 8 tablespoons unsalted butter, 1 stick, melted and still warm
- 1 3/4 cups all-purpose flour
- 1 cup pecans, chopped
Instructions
For the cake
- Preheat an oven to 350°F. Butter and flour a 9-inch springform pan or a 9-inch cake pan with 3-inch sides.
- Prepare the crumb topping.
- In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg and salt. In the bowl of an electric mixer fitted with the flat beater, beat together the butter and brown sugar on medium-high speed until well combined. Beat in the eggs, one at a time, scraping down the sides of the bowl with a rubber spatula. Add the pumpkin puree and sour cream and mix. Stir in the flour mixture. The batter will be quite thick.
- Spread batter in the prepared pan. Top with the crumb topping. Bake until a toothpick inserted into the center of the cake comes out clean, about 40-50 minutes. Transfer the pan to a wire rack and let cool for about 15 minutes. Remove the sides from the pan and slide the cake onto the rack.
For the crumb topping
- Whisk sugars, cinnamon, salt, and butter in medium bowl to combine. Add flour and pecans and stir until mixture resembles thick, cohesive dough. Set aside to cool to room temperature, 10 to 15 minutes.


Rachel, this looks sooo good. I love crumb cake and I also love how you breakdown the difference between crumb cake and coffee cake – how knew it was so involved? Pinning for Thanksgiving – a total different use for pumpkin rather than a plain pumpkin pie.
Dang, that crumb to cake ratio is something else! My husband is a major lover of crumb so that would be perfect for him, and for me too since he’d steal half my crumb anyways! What a great recipe!
That’s my kinda cake right there! Pass me a piece right now!!
I feel like a just took a crash course on coffee vs crumb cakes, but I think I prefer crumb cake…anything with a 1:1 crumb to cake ratio is fine by me! You cake looks delicious! And I LOVE all that crumble! Pinned!
Thanks Lindsey! I know, I felt like I spent so long reading about the differences that I’m an expert now, haha! And oh ya, the more crumb the better.
Love that crumb layer on top, it’s the perfect touch! I’ll find any excuse to eat pumpkin right now, this is perfect! Pinning!
I don’t care what you call this cake, I want it! That crumb layer is making me swoon!
that first shot though… you know what’s up!
this is OHMYGODSODELICIOUSINEEDTHISNOW material.
seriously, ALL THAT CRUMB. yes please!
Crumb cakes are so fun to make! But yours sounds incredibly delicious with the pumpkin and spices. Pinned for later because I like sour cream batters and I’m sure this one is great too, especially combined with the pumpkin puree, it gives me the impression of a very moist and flavorful cake.
Thanks Oana – it definitely is! Thanks for the pin!
Haha – I had no idea about the difference between crumb cake and coffee cake either! Whatever this is, I’d eat MULTIPLE slices – holy moly. That crumb on top is making me swoon!
Great photos! This cake looks extra crumbly- which is the best part!
