What Makes This Recipe So Good
- Fast and fuss-free: The air fryer heats quickly and bakes evenly, so you can enjoy fresh coffee cake in under an hour.
- Soft crumb, crisp top: The cake stays moist while the streusel turns perfectly crunchy—ideal texture in every bite.
- Small-batch friendly: Great for couples, small families, or when you don’t want a huge cake hanging around.
- Pantry staple ingredients: Nothing unusual or hard to find. You likely have everything on hand.
- Adaptable: Add nuts, fruit, or a simple glaze to switch it up without changing the method.
What You’ll Need
- For the streusel:
- 1/3 cup all-purpose flour
- 1/3 cup light brown sugar, packed
- 1 teaspoon ground cinnamon
- 1/8 teaspoon fine salt
- 3 tablespoons cold unsalted butter, cubed
- Optional: 1/4 cup chopped pecans or walnuts
- For the cake batter:
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon fine salt
- 1/2 cup granulated sugar
- 1/4 cup unsalted butter, softened
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1/2 cup sour cream (or plain Greek yogurt)
- 2 tablespoons milk
- Equipment:
- Air fryer with a basket or oven-style drawer
- 6- to 7-inch round cake pan or springform pan that fits in your air fryer
- Parchment paper (optional, for lining)
- Mixing bowls and a fork or pastry cutter
Step-by-Step Instructions
- Prepare the pan: Lightly grease your 6- to 7-inch pan.
Line the bottom with parchment if you’d like cleaner slices. Set aside.
- Preheat the air fryer: Set to 320°F (160°C) for 5 minutes. Preheating helps the cake rise evenly and avoids a gummy center.
- Make the streusel: In a small bowl, combine flour, brown sugar, cinnamon, and salt.
Add cold butter cubes and cut in with a fork until you have pea-sized crumbles. Stir in nuts if using. Refrigerate while you mix the batter to keep it crumbly.
- Mix dry ingredients: In a medium bowl, whisk flour, baking powder, baking soda, and salt.
This keeps the crumb light and uniform.
- Cream butter and sugar: In a separate bowl, beat the softened butter and granulated sugar until fluffy and pale, about 1–2 minutes. Add the egg and vanilla, and mix until smooth.
- Add sour cream and milk: Blend in the sour cream until fully incorporated, then mix in the milk. The batter will look silky and slightly thick.
- Combine: Add the dry ingredients to the wet and fold gently with a spatula until just combined.
Avoid overmixing to keep the cake tender.
- Layer the batter and streusel: Spread half the batter into the prepared pan. Sprinkle about one-third of the streusel over it. Add the remaining batter and smooth the top.
Finish with the remaining streusel in an even layer.
- Air fry: Place the pan in the air fryer basket. Cook at 320°F (160°C) for 22–28 minutes, depending on your model and pan size. The cake is done when a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
- Rest and cool: Let the cake sit in the pan for 10 minutes.
Run a knife around the edge, then lift out or release the springform. Cool another 10–15 minutes before slicing to keep the crumb from crumbling.
- Optional glaze: Stir 1/2 cup powdered sugar with 1–2 teaspoons milk and a drop of vanilla to make a drizzle. Spoon over the cooled cake for extra sweetness.
Storage Instructions
- Room temperature: Keep covered at room temp for up to 2 days.
A cake dome or airtight container prevents the streusel from softening.
- Refrigerator: Store in an airtight container for up to 5 days. Warm a slice in the air fryer at 300°F for 2–3 minutes to revive the crunch.
- Freezer: Wrap slices individually in plastic, then place in a freezer bag for up to 2 months. Thaw at room temp and re-crisp in the air fryer for a minute or two.
Why This Is Good for You
- Portion control: A small-batch cake helps you enjoy a treat without overdoing it or letting leftovers go stale.
- Less heat, less time: The air fryer uses less energy and doesn’t heat up the whole kitchen—great for warm days or quick bakes.
- Balanced indulgence: Pair a slice with protein-rich yogurt or eggs for a satisfying breakfast that feels special but grounded.
- Customizable ingredients: You control the sugar, use whole-wheat pastry flour for part of the mix, or add fiber with fruit or nuts.
What Not to Do
- Don’t skip preheating: A cold air fryer can lead to uneven rise and a dense center.
- Don’t overmix: Stir just until combined.
Overworking the batter toughens the crumb.
- Don’t overload the pan: Use the right size pan and don’t fill more than about two-thirds full, or it may not cook through.
- Don’t crank the heat: Higher temps brown the top too fast and leave the middle raw. Stick with 320°F (160°C).
- Don’t cut too soon: Slicing hot cake makes it fall apart. Let it rest for structure to set.
Variations You Can Try
- Blueberry coffee cake: Fold 1/2 cup fresh or frozen blueberries into the batter.
Toss berries with 1 teaspoon flour first to prevent sinking.
- Apple-cinnamon: Add 1/2 cup finely diced apple to the batter and a pinch of nutmeg to the streusel.
- Lemon poppy seed: Add 1 tablespoon lemon zest and 1 tablespoon poppy seeds to the batter. Finish with a lemon glaze.
- Maple-pecan streusel: Replace 2 tablespoons of the brown sugar in the streusel with maple syrup and add chopped pecans.
- Gluten-free: Use a 1:1 gluten-free baking flour blend and check doneness a minute or two early, as textures can vary.
- Lighter swap: Use Greek yogurt instead of sour cream and reduce streusel by a couple of tablespoons if you prefer less sweetness.
FAQ
Can I bake this in the oven instead?
Yes. Use a 6- to 7-inch pan and bake at 350°F (175°C) for 28–35 minutes, or until a toothpick comes out mostly clean.
The texture will be similar, though the air fryer gives a slightly crisper top.
What if I don’t have sour cream?
Plain Greek yogurt works well and keeps the cake moist. Choose full-fat or 2% for the best texture.
How do I prevent the top from over-browning?
If the streusel browns too quickly, tent a small piece of foil over the pan during the last 5–8 minutes. Leave space for air to circulate.
Can I double the recipe?
You can, but bake in two batches unless you have a larger air fryer and two pans.
Overcrowding affects airflow and leads to uneven baking.
Why is my cake gummy in the center?
It likely needs more time, or your pan is too deep. Check doneness in multiple spots, and extend the bake in 2–3 minute increments until the tester has just a few moist crumbs.
What’s the best pan to use in an air fryer?
A 6- or 7-inch metal cake pan or springform pan works best. Metal heats quickly and promotes even baking.
Make sure it fits with room for airflow around it.
Can I make it ahead?
Yes. Bake the cake, cool completely, and store covered at room temp for up to 24 hours. Rewarm a slice in the air fryer for a minute or two to refresh the crumb and streusel.
