Air Fryer Lemon Blueberry Mini Cakes

These air fryer lemon blueberry mini cakes are soft, fluffy, and full of fresh flavor. They come together quickly and taste like something you’d get from a bakery.

The combination of lemon and blueberry is always a winner. The lemon adds a nice brightness, and the blueberries give you little bursts of sweetness in every bite.

What I love about making these in the air fryer is how fast and easy it is. No need to heat up your whole oven for a small batch of cakes.

You only need a few basic ingredients and some ramekins. The batter takes just minutes to mix, and the air fryer does the rest.

Once they’re done, you drizzle them with a simple lemon glaze that takes these mini cakes to the next level. They’re perfect for a weekend treat or a quick dessert.

Ingredients

For the Cakes

• 2/3 cup All-Purpose Flour
• 1/2 tsp Baking Powder
• 1/4 tsp Salt
• 1/3 cup Granulated Sugar
• 1 Large Egg
• 1/4 cup Sour Cream
• 3 tbsp Melted Butter
• 1 tbsp Fresh Lemon Juice
• 1 tsp Lemon Zest
• 1/2 cup Fresh Blueberries

For the Glaze

• 1/2 cup Powdered Sugar
• 1 tbsp Fresh Lemon Juice
• 1/2 tsp Lemon Zest

How To Make

Step 1

In a bowl, whisk together flour, baking powder, and salt. In another bowl, beat sugar and egg until fluffy, then mix in sour cream, melted butter, lemon juice, and lemon zest.

Step 2

Fold dry ingredients into wet ingredients until just combined. Gently fold in blueberries, being careful not to crush them.

Step 3

Grease four 4-oz ramekins and divide batter evenly among them, filling about two-thirds full.

Step 4

Preheat air fryer to 320°F. Place ramekins in the basket and cook for 14-16 minutes until tops are golden and spring back when touched.

Step 5

While cakes cool, whisk together powdered sugar, lemon juice, and lemon zest until smooth and pourable. Add more lemon juice if too thick.

Step 6

Let cakes cool for 5 minutes, then drizzle generously with lemon glaze. Serve warm or at room temperature.

Tips

Toss Blueberries in Flour First

Before folding the blueberries into the batter, toss them in about a teaspoon of flour from your measured amount. This light coating helps them stay suspended in the batter instead of sinking straight to the bottom during cooking.

If they sink, you’ll end up with all the blueberries stuck to the bottom of the ramekin and plain cake on top. That quick flour toss makes a big difference in how evenly they’re distributed in the finished cakes.

Don’t Skip Preheating the Air Fryer

Let your air fryer run at 320°F for about 3 minutes before you place the ramekins inside. If you put them in a cold air fryer, the batter sits there while the temperature slowly climbs, and the cakes won’t rise properly.

A preheated air fryer gives the batter that initial burst of heat it needs to puff up right away. This is what gives you that nice dome on top instead of a flat, dense cake.

Check the Size of Your Ramekins

The recipe calls for 4-oz ramekins, and sticking to that size really matters here. If you use bigger ramekins, the batter will spread too thin and the cakes will dry out before they’re done. If you use smaller ones, the batter will overflow and make a mess in your air fryer.

Fill each ramekin about two-thirds full, no more. The batter needs that extra space because it will rise as it cooks.

If you only have 6-oz ramekins, you can still use them – just know your cakes will be shorter and you may need to reduce the cook time by 2-3 minutes.

Frequently Asked Questions

Can I use silicone molds instead of ramekins in the air fryer?

Yes, silicone molds work great for this recipe and are actually a popular choice for air fryer baking. Just make sure they fit comfortably in your air fryer basket with a little space around them for air to circulate properly.

One thing to keep in mind is that silicone molds are flexible, so place them on a small piece of parchment or a trivet to keep them steady when you move them in and out of the basket.
