Nothing says fall quite like the aroma of pumpkin and spice filling your kitchen. This Pumpkin Spice Crumb Cake is on heavy rotation in our household during the fall season because it combines the best of both worlds: a tender, flavorful pumpkin cake base and a buttery brown-sugar crumb topping that just melts in your mouth. It’s perfect for breakfast, brunch, or as a sweet afternoon pick-me-up with a cup of coffee.

Unlike dense pumpkin breads or overly sweet desserts, this delicious crumb cake strikes the ideal balance of being moist and rich without being heavy and warmly spiced without being overpowering. And if you really want to take it up a notch, a drizzle of pumpkin-spiced glaze adds an irresistibly sweet touch that really makes this cake shine. But be warned that once it comes out of the oven, don’t be surprised if it all disappears in one sitting!

3 delicious layers of pumpkin spice crumb cake

1. The Pumpkin Cake:

Soft, moist, and infused with pumpkin spice, the cake base sets the tone for the whole dessert. It’s rich from butter and oil, subtly sweet from brown sugar, and perfectly balanced by pumpkin purée for a velvety texture that stays moist for days.

2. The Crumb Topping:

This buttery streusel topping is what makes this cake so irresistible. Cold butter is cut into brown sugar, flour, and pumpkin spice to create crumbly, golden clusters that bake into a sweet, slightly crunchy layer — the perfect contrast to the soft cake beneath.

3. The Pumpkin-Spiced Glaze:

Completely optional but highly recommended (because it’s not crumb cake without a little bit of icing!), this simple glaze adds a glossy finish to the cake. It’s made with confectioners’ sugar, a touch of pumpkin spice, and milk for that beautiful drizzle that ties everything together.

Ingredients needed

For the pumpkin cake:

• Melted unsalted butter
• Light brown sugar: Deepens the flavor and pairs perfectly with pumpkin.
• 2 large eggs: Provide structure and stability to the cake.
• 1 cup canned pumpkin puree: The star ingredient, adding moisture and pumpkin flavor.
• ¼ cup neutral oil (like avocado oil): Helps the cake stay moist even after a day or two.
• Pumpkin spice blend: Brings warm, aromatic spice to the batter.
• Fine sea salt: Balances and enhances the sweetness.
• Baking powder + baking soda: Give the cake its light, fluffy lift.
• All-purpose flour: Forms the base and structure of the cake.

For the crumb topping:

• Light brown sugar: Adds sweetness and a hint of molasses flavor to the streusel.
• All-purpose flour: Binds the topping and creates that crumbly texture.
• Pumpkin spice blend: Enhances the seasonal aroma.
• Pinch of salt: Balances the sweetness.
• Unsalted butter, cold and cubed: Creates that classic buttery crumb once baked.

For the glaze (optional):

• Confectioners’ sugar: Creates a smooth, sweet glaze.
• Pumpkin spice blend: Adds that signature fall touch.
• Pinch of salt: Keeps the glaze balanced.
• 3 to 5 teaspoons milk: Adjust the glaze to your desired consistency.

How to make pumpkin spice crumb cake

1. Make the crumb topping

Mix brown sugar, flour, pumpkin spice, and salt in a small bowl. Then add the cold cubed butter and pinch into the flour mixture until it forms crumbles. Pop in the fridge while you prepare the cake batter so that it stays moistened.

2. Prepare the cake batter

In a large bowl, whisk together brown sugar and eggs until foamy. Whisk in the pumpkin puree, melted butter, oil, pumpkin spice, salt, baking powder, and baking soda. Fold in the flour until just combined into a thick and smooth batter, taking care not to overmix.

3. Assemble and bake

Pour the batter into a greased 9×5-inch loaf pan and sprinkle the crumb topping on top. Bake in the oven at 350°F for 40-45 minutes, or until a toothpick inserted into the center comes out clean.

4. Cool the cake

If serving immediately, let the cake cool in the pan on a wire rack for about 15 minutes. If making the glaze, allow the cake to cool almost completely until it’s still slightly warm.

5. Make the glaze (optional)

Whisk together confectioners’ sugar, pumpkin spice, salt, and milk. Start with 3 teaspoons of milk, adding more if needed. Drizzle over the cooled cake before serving.

Frequently asked questions

1. Can I use fresh pumpkin instead of canned purée?
   Yes, you can! Just be sure to cook and mash it until completely smooth and strain out any excess liquid. Homemade pumpkin puree tends to be more watery than canned, so draining helps keep the cake’s texture light and fluffy.
   
2. How do I keep the crumb topping from sinking into the cake?
   Make sure your crumb mixture is well-chilled before sprinkling it on top of the batter. Cold butter helps the crumbs stay on the surface as the cake bakes, creating that distinct, golden-brown layer.
   
3. Can I make this pumpkin crumb cake ahead of time?
   Absolutely! You can bake the cake one day in advance, let it cool completely, and store it covered at room temperature. For the best texture, drizzle the glaze just before serving.
   
4. What’s the best way to reheat leftover slices?
   Warm individual pieces in the microwave for 10–15 seconds, or reheat larger portions in a 300°F oven for about 10 minutes. The cake stays soft and moist, and the crumb topping crisps up beautifully again.

How to store pumpkin spice crumb cake

• Room temperature: Store covered at room temperature for up to 3 days.
• To refrigerate: The pumpkin spice crumb cake keeps well in the fridge for up to 5 days. Just let it come to room temp before serving or pop it in the microwave to reheat gently.
• To freeze: Freeze individual slices (without glaze) for up to 2 months. Thaw overnight in the fridge or warm briefly in the microwave before serving.
