Ingredients for Air Fryer Pumpkin Spice Crumb Cake

Here’s everything you’ll need to make this cozy fall treat – I promise you probably have most of it in your pantry already! The magic happens when these simple ingredients come together:

For the Cake:

• 1 cup all-purpose flour – spooned and leveled (don’t pack it down!)
• ½ cup granulated sugar – the perfect amount to let the pumpkin spice shine
• 1 teaspoon baking powder – fresh is best for maximum lift
• ½ teaspoon pumpkin pie spice – or make your own blend if you’re feeling fancy
• ¼ teaspoon salt – just enough to balance the sweetness
• ½ cup pumpkin puree – NOT pumpkin pie filling (I always use Libby’s)
• ¼ cup milk – whole milk gives the richest texture
• 1 large egg – room temperature blends in smoother
• 2 tablespoons melted butter – slightly cooled (I microwave for 20 seconds)

For That Irresistible Crumb Topping:

• ½ cup packed brown sugar – dark brown sugar adds deeper flavor
• ¼ cup all-purpose flour – helps create those perfect crumbs
• 2 tablespoons cold butter – straight from the fridge, cubed
• ½ teaspoon cinnamon – because you can never have too much spice!

See? Nothing complicated – just good, simple ingredients that make your kitchen smell like autumn heaven. Now let’s get mixing!

Equipment You’ll Need

Don’t worry—you won’t need any fancy gadgets for this! Here’s what’s essential:

• Air fryer – Obviously! (Mine’s a 6-quart, but any size works as long as your pan fits.)
• Small cake pan – A 6-inch round or square pan that fits snugly inside your air fryer basket.
• 2 mixing bowls – One for the batter, one for the crumb topping—easy cleanup.
• Whisk & spatula – For blending the batter smoothly and scraping every last bit of that delicious crumb topping.
• Measuring cups/spoons – Precision matters, especially with baking powder and spices.

That’s it! No stand mixer, no special tools—just simple gear for simple, scrumptious results.

How to Make Air Fryer Pumpkin Spice Crumb Cake

Okay, let’s get baking! This comes together so fast you’ll barely have time to lick the spoon (though I won’t judge if you do). Here’s exactly how I make my favorite fall treat:

1. Preheat and Prep

First things first – get that air fryer ready! Set it to 350°F (175°C) and let it heat up while you mix everything. Lightly grease your cake pan with butter or non-stick spray – I use my fingers to get into all the corners. Trust me, you don’t want to skip this step!

2. Mix the Dry Ingredients

In your first bowl, whisk together:

• 1 cup flour
• ½ cup sugar
• 1 tsp baking powder
• ½ tsp pumpkin pie spice
• ¼ tsp salt

Whisk until you don’t see any lumps – this ensures the spices distribute evenly. I always take a deep sniff at this point because that spice combo smells like fall in a bowl!

3. Blend the Wet Ingredients

In your second bowl, mix:

• ½ cup pumpkin puree
• ¼ cup milk
• 1 egg
• 2 tbsp melted butter

Whisk until smooth and creamy – about 30 seconds should do it. No need to overmix here!

4. Combine Everything

Pour the wet ingredients into the dry ingredients and stir gently with a spatula just until combined. A few small lumps are okay – overmixing makes tough cake! The batter will be thick but pourable.

5. Make the Crumb Topping

Now for the best part! In a small bowl, mix:

• ½ cup brown sugar
• ¼ cup flour
• ½ tsp cinnamon

Add 2 tbsp cold butter cubes and use your fingers to pinch everything together until you get coarse crumbs. Don’t overwork it – you want some big, buttery pieces!

6. Assemble and Bake

Pour the batter into your prepared pan, then sprinkle the crumb topping evenly over the top. Gently press the crumbs down just slightly so they stick. Pop it in the air fryer and bake for 20-25 minutes until golden brown and a toothpick comes out clean. Mine’s usually perfect at 22 minutes!

7. Cool and Enjoy

Let the cake cool in the pan for at least 10 minutes before slicing – I know it’s hard to wait, but this helps the crumb set. Then dig in! The warm spices, tender crumb, and buttery topping are pure autumn magic.

Tips for the Perfect Air Fryer Pumpkin Spice Crumb Cake

After making this cake more times than I can count (no regrets!), here are my can’t-miss tricks:

• Toothpick test FTW: Start checking at 20 minutes—it should come out with moist crumbs, not wet batter. The cake keeps cooking a bit after you pull it out!
• Fresh pumpkin puree matters: Canned works great, but avoid the pie filling kind (too sweet). I drain excess liquid from homemade puree with a cheesecloth.
• Temperature is key: Cold butter makes the best crumb topping—if it melts while mixing, pop the bowl in the freezer for 5 minutes.
• Customize your spice: Add a pinch of cardamom or ginger if you like extra warmth. I sometimes sneak in orange zest too!

These little tweaks take a good cake to “oh wow, can I have the recipe?” territory.

Variations and Substitutions

One of my favorite things about this recipe is how easily you can tweak it to suit your taste or what’s in your pantry! Here are my go-to switches:

• Gluten-free? Swap the flour with your favorite 1:1 gluten-free blend – I’ve had great results with Bob’s Red Mill.
• Dairy-free delight: Use almond milk and coconut oil instead of regular milk and butter. The crumb topping still gets perfectly crisp!
• Nutty twist: Fold in ¼ cup chopped pecans or walnuts into the batter for extra crunch.
• Chocolate lover’s dream: Toss in ½ cup chocolate chips – the bittersweet kind pairs beautifully with the warm spices.
• Spice it up: Add a pinch of black pepper or cayenne if you like a little heat with your sweet.

The possibilities are endless – make it your own!

Serving Suggestions

Oh, let me tell you how I love to serve this cake – warm from the air fryer is absolute perfection! The crumb topping gets extra crisp while the pumpkin spice flavors really pop. My favorite way? A big scoop of vanilla ice cream melting over the top. The cold creaminess against the warm cake is pure magic. For extra decadence, drizzle with caramel sauce or a dollop of whipped cream. And don’t even get me started on how amazing it pairs with a hot cup of coffee on a chilly fall morning!

Storage and Reheating

Here’s the best way to keep your crumb cake tasting fresh (though let’s be honest – mine rarely lasts more than a day!): Store leftovers in an airtight container at room temperature for 2 days, or refrigerate for up to 5 days. To bring back that just-baked magic, pop slices in the air fryer at 300°F for 2-3 minutes – the topping crisps right back up!

Frequently Asked Questions

I get asked these questions all the time about my Air Fryer Pumpkin Spice Crumb Cake – here’s everything you need to know:

Can I use canned pumpkin puree?

Absolutely! I use Libby’s canned pumpkin puree all the time – just make sure it’s 100% pumpkin, not pumpkin pie filling (which has added sugar and spices). If using homemade puree, drain any excess liquid in a cheesecloth first.

Why did my crumb topping melt into the cake?

This happens if your butter was too soft when making the topping. The butter should be cold straight from the fridge – I even chill my bowl first! If it starts melting while you’re working, pop everything in the freezer for 5 minutes.

How do I prevent overcooking?

Air fryers can vary, so start checking at 20 minutes with a toothpick. It should come out with moist crumbs, not wet batter. The cake continues cooking a bit after removal, so err on the slightly underdone side.

Can I double this recipe?

You can, but bake in batches – air fryers don’t do well with overcrowding. I recommend using two small pans rather than one large one for even cooking. Add 2-3 minutes to the baking time if needed.

What if I don’t have pumpkin pie spice?

No worries! Mix ½ tsp cinnamon with ¼ tsp nutmeg and ¼ tsp ginger – it’s nearly identical. I sometimes add a pinch of cloves or allspice too for extra warmth.
