Why make Blondies in the air fryer?
Making white brownies in an air fryer is a quick and easy method that gives an excellent result. The air fryer ensures even heat distribution, which helps bake the cake perfectly without burning the edges. You also save time, as an air fryer often requires a shorter baking time than a traditional oven. It’s also an energy-efficient method, which makes it an environmentally friendly choice for baking enthusiasts. Finally, with an air fryer you can achieve a crispy crust without losing the soft, fudgy centre that makes blondies so delicious.
What is a blondie?
Blondies are a type of cake that closely resembles brownies, but instead of cocoa or dark chocolate they use white chocolate. Blondies have a rich, full flavour of caramel and vanilla that comes from the butter, sugar and vanilla extract. The texture is typically dense and fudgy, just like traditional brownies, but with a lighter flavour and colour. Blondies can also contain various fillings, such as nuts, white chocolate chips or dried fruit, to add extra texture and flavour nuances.
Who invented it and where does the cake come from?
Blondies are known from American cookbooks of the 20th century, where they were often called “brown sugar brownies”. Their exact origin is unclear, but the cake is believed to come from the USA. The white chocolate version, as we know it today, is a more recent variant. Blondies were created as a variation of brownies to offer a different flavour profile with the same delicious, fudgy texture.
How to get a fudgy centre and a crisp crust
To achieve the perfect blondie with a soft, fudgy centre as well as a crisp crust, it’s important to follow a few key techniques:
- Don’t overmix: Once you’ve added the flour to the batter, stir gently until the ingredients are just combined. Overmixing can result in a tough cake.
- Watch the baking time: Blondies should be baked until the edges are golden, but the centre should still be slightly soft. Use a toothpick to check if the cake is done. If the toothpick comes out with a few moist crumbs, the cake is ready.
- Cool in the tin: Let the blondies cool completely in the baking tin. This helps set the cake and makes it easier to cut without crumbling.
- Use the air fryer correctly: Preheat your air fryer and use a suitable baking tin that fits inside it. This ensures even heat distribution and a crispy crust.
Which toppings go well with blondies?
Blondies can be decorated with a range of different toppings that add extra flavour and texture. Here are a few suggestions:
- White chocolate glaze: A rich and creamy white chocolate glaze can add an extra sweet and decadent dimension to your blondies.
- Fresh berries: Berries such as raspberries, blueberries or strawberries provide a fresh and tangy contrast to the sweet cake.
- Nuts: Chopped nuts such as pecans, walnuts or almonds can be sprinkled over the cake for an extra crunchy texture.
Add a pinch of cinnamon to the batter to enhance the flavour of the white chocolate and give your blondies a warm, spiced undertone. This little twist can take your white brownies to the next level.

FAQ
A square or round tin of about 18–20 cm works well for this recipe and fits most medium-sized air fryers. Always check that the tin sits in the basket with a little space around the edge. If you use a smaller tin, the cake will be thicker and need a few extra minutes.
Bake it at 160 °C for 25–30 minutes and insert a toothpick into the centre. It’s ready when the toothpick comes out with just a few moist crumbs – no runny batter, but not completely clean either. The edges should be golden, and the centre can still be slightly soft, as it sets while the cake cools in the tin.
Yes, blondies can be frozen for up to 3 months. Let the cake cool completely, cut it into pieces and wrap them well. Thaw them at room temperature or warm them for a few minutes in the air fryer at 150 °C.
