This blueberry cake is a quick, moist treat made right in the air fryer—no oven needed! The fresh blueberries burst with flavor, making it perfect for a cozy afternoon or weekend dessert.
Introduction
I first tried making this blueberry cake in my air fryer on a rainy Saturday when I didn’t want to heat up the whole kitchen with the oven. I was honestly surprised how moist and tender it turned out! The trick I learned was to toss the blueberries in a little flour before folding them into the batter—this keeps them from sinking to the bottom and helps the cake bake evenly. Plus, using yogurt instead of butter makes the cake lighter and adds a subtle tang that balances the sweetness perfectly. I’ve made this a handful of times now, and it’s become my go-to quick dessert or weekend treat. It’s not fancy, but it’s comforting and packed with fresh berry flavor, exactly what I want when I’m craving something sweet but simple. The cake has a lovely golden crust with a soft crumb inside, and the blueberries burst with juice in every bite. If you have an air fryer, this recipe is a little gem you’ll want to keep around.
What You'll Need
One 7-inch cake, 6 servings
- 1 cup all-purpose flour, sifted
- 1/2 cup granulated sugar
- 1/2 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup plain yogurt, at room temperature
- 1/4 cup vegetable oil
- 1 large egg, at room temperature
- 1 teaspoon vanilla extract
- 1 cup fresh blueberries, rinsed and patted dry
- 1 tablespoon all-purpose flour (for coating blueberries)
How To Do It
Step 1
Start by mixing the dry ingredients: sift together the flour, baking powder, baking soda, salt, and sugar in a large bowl. Sifting helps combine everything evenly and aerates the flour, which makes the cake lighter. It's important to mix these well to avoid any pockets of leavening agents that could cause uneven rising. Take your time here to get a uniform mixture.
⏱ Time: 5 minutes
✓ Doneness: Dry ingredients are evenly combined with no clumps
Step 2
In a separate bowl, whisk together the yogurt, vegetable oil, egg, and vanilla extract until smooth. Using room temperature ingredients helps everything blend more easily and prevents the batter from curdling. The yogurt adds moisture and a slight tanginess that balances the sweetness and keeps the cake tender.
⏱ Time: 3 minutes
✓ Doneness: Wet ingredients are smooth and well combined without lumps
Step 3
Make a well in the dry ingredients and pour in the wet mixture. Gently fold them together with a spatula just until you don’t see dry flour anymore. Overmixing can develop gluten and make the cake tough, so be gentle here. The batter should be slightly thick but smooth.
⏱ Time: 3 minutes
✓ Doneness: Batter is smooth with no visible flour streaks but not overmixed
Step 4
Coat the blueberries with 1 tablespoon of flour to prevent them from sinking to the bottom of the cake. This simple step helps suspend the berries evenly throughout the batter, so you get blueberry goodness in every bite rather than just at the bottom.
⏱ Time: 2 minutes
✓ Doneness: Blueberries are lightly coated and separate, not clumped
Step 5
Fold the floured blueberries gently into the batter. Be careful not to break the berries or overmix. This keeps the batter light and the blueberries intact, which will burst with flavor during baking.
⏱ Time: 2 minutes
✓ Doneness: Blueberries are evenly distributed without breaking
Step 6
Lightly grease a 7-inch round pan that fits inside your air fryer basket. Pour the batter into the pan and smooth the top with a spatula. Greasing ensures the cake doesn’t stick and comes out easily once baked.
⏱ Time: 3 minutes
✓ Doneness: Batter is evenly spread and smooth on top
Step 7
Preheat your air fryer to 320°F (160°C) for about 3 minutes. Preheating is important so the cake starts baking immediately and rises properly. Without preheating, the batter may cook unevenly or take longer.
⏱ Time: 3 minutes
✓ Doneness: Air fryer reaches temperature and is ready for baking
Step 8
Place the cake pan in the air fryer basket and bake for 25-30 minutes. Check at 25 minutes by inserting a toothpick in the center; it should come out clean or with a few moist crumbs. Avoid opening too often, as the temperature drop can affect rising.
⏱ Time: 25-30 minutes
✓ Doneness: Golden brown top and toothpick comes out clean
Step 9
Remove the cake from the air fryer and let it cool in the pan for 10 minutes before transferring to a wire rack. Cooling allows the cake to set and prevents it from breaking apart. Serve warm or at room temperature for best flavor.
⏱ Time: 10 minutes
✓ Doneness: Cake is firm enough to remove from pan without breaking
Pro Tips
Always use room temperature eggs and yogurt.
Room temperature ingredients blend more smoothly and evenly, which helps create a uniform batter. Cold ingredients can cause the batter to curdle or mix unevenly, resulting in a denser cake with inconsistent texture.
Don’t overmix the batter once the wet and dry ingredients are combined.
Overmixing develops gluten in the flour, which makes cakes tough instead of tender. Mixing just until combined keeps the crumb soft and light, which is especially important for quick cakes like this one.
Preheat the air fryer before baking the cake.
Preheating ensures the cake starts cooking immediately at the right temperature. This helps the cake rise properly and develop a golden crust. Skipping preheating can cause uneven cooking and a denser texture.
Coat blueberries with flour before folding into batter.
This simple step prevents the berries from sinking to the bottom, which keeps them evenly distributed. It also helps absorb some moisture from the berries, preventing the batter from becoming too wet in spots.
Use a pan that fits snugly in your air fryer basket.
A pan that’s too small or too large can affect cooking times and airflow, leading to uneven baking. Using the right size ensures even heat circulation and consistent results.
Let the cake cool in the pan before removing it.
Cooling allows the cake to set and reduces the chance of it breaking apart when you take it out. It also helps the crumb finish cooking gently for a better texture.
Use fresh blueberries rather than frozen.
Frozen berries release extra moisture when thawing, which can make the batter soggy and affect baking. Fresh berries maintain their texture and flavor better in this quick baking method.
Common Mistakes to Avoid
Overmixing the batter
Why it happens Many home cooks want to make sure everything is fully combined and end up stirring too much, thinking it will improve the texture.
Fix Mix just until the flour disappears and the batter looks smooth but still slightly lumpy. Stop stirring once combined to avoid developing gluten which makes the cake tough.
Not preheating the air fryer
Why it happens It’s easy to forget or assume the air fryer heats quickly enough during baking.
Fix Always preheat for 3-5 minutes before adding the cake. This helps the cake rise properly and bake evenly with a nice crust.
Using wet or frozen blueberries without drying
Why it happens Sometimes berries are rinsed but not dried well, or frozen berries are used straight from the freezer.
Fix Pat blueberries dry thoroughly before using and avoid frozen berries for this recipe to prevent soggy batter and uneven baking.
Using a pan that’s too large or too small
Why it happens Not measuring the pan size can lead to uneven cooking or longer baking times.
Fix Use a 7-inch round pan that fits comfortably in your air fryer basket for even heat circulation and proper baking.
Removing cake too soon from pan
Why it happens Impatience or wanting to serve immediately can cause the cake to break apart.
Fix Let the cake cool in the pan for at least 10 minutes so it firms up and is easier to remove without crumbling.
Variations
Lemon Blueberry Air Fryer Cake
Add 1 tablespoon of fresh lemon zest and 2 tablespoons of lemon juice to the wet ingredients for a bright citrus twist. This complements the blueberries beautifully and adds a fresh zing to the cake.
Note: The lemon juice adds extra acidity, so reduce the yogurt slightly to keep the batter balanced and avoid curdling.
Blueberry Almond Air Fryer Cake
Stir in 1/2 cup sliced almonds and 1/2 teaspoon almond extract to the batter for a nutty flavor and crunchy texture. Sprinkle extra almonds on top before baking for a pretty finish.
Note: Almonds add texture, so be gentle folding to avoid breaking berries; baking time remains the same.
Gluten-Free Blueberry Air Fryer Cake
Swap the all-purpose flour for a gluten-free baking blend that includes xanthan gum. This makes the cake safe for gluten-sensitive eaters while keeping a tender crumb.
Note: Gluten-free flours absorb moisture differently; you may need to add a tablespoon more yogurt or reduce baking time slightly.
Vegan Blueberry Air Fryer Cake
Use a flax egg (1 tbsp ground flaxseed + 3 tbsp water) instead of the egg and substitute plant-based yogurt. Use coconut oil instead of vegetable oil for richness.
Note: The flax egg helps bind the batter but may result in a slightly denser texture; baking time may need a minute or two longer.
Blueberry Streusel Topped Air Fryer Cake
Top the batter with a simple streusel made from flour, brown sugar, and butter before baking. This adds a sweet, crunchy topping that contrasts nicely with the soft cake.
Note: Add the streusel just before baking and watch closely near the end to prevent burning.

Reheating
Reheat slices in the microwave for 15-20 seconds or in a 300°F oven for 5-7 minutes. Adding a small splash of milk before reheating can help keep it moist. Avoid overheating to prevent drying.
Make Ahead
You can prepare the batter a few hours ahead and keep it refrigerated. Bring to room temperature before baking. The baked cake can also be made a day ahead and stored covered at room temperature or in the fridge.
FAQ
Can I use frozen blueberries instead of fresh?
Frozen blueberries release more water when thawed, which can make the batter too wet and affect baking. If you must use frozen, toss them in flour and add them frozen to the batter without thawing, but expect a slightly wetter texture.
What if I don’t have an air fryer? Can I bake this in the oven?
Absolutely! Bake in a preheated oven at 350°F for about 30-35 minutes or until a toothpick comes out clean. The texture will be similar, but the air fryer gives a slightly crisper crust.
How do I know when the cake is done in the air fryer?
Insert a toothpick or skewer in the center; if it comes out clean or with a few moist crumbs, the cake is done. The top should be golden brown and spring back lightly when touched.
Can I substitute yogurt with sour cream or buttermilk?
Yes, both sour cream and buttermilk add moisture and acidity that help tenderize the crumb. Use the same amount, but adjust liquid slightly if the batter feels too thick or thin.
Why do I need to coat the blueberries with flour?
Coating blueberries with flour prevents them from sinking to the bottom during baking. It also absorbs some of the berry juice, keeping the batter from becoming too wet in spots.
Can I make this cake dairy-free?
Yes! Use a plant-based yogurt and oil instead of butter. Make sure your yogurt alternative is thick and plain for best texture and flavor.
What size pan should I use in the air fryer?
A 7-inch round pan fits well in most air fryer baskets and allows even cooking. Using a pan that’s too large or small can affect cooking time and texture.
How long does the batter keep if I make it ahead?
You can refrigerate the batter for up to 4 hours before baking. Let it come to room temperature before cooking to ensure even baking and proper rise.
