Ingredients
120 grams flour (4¼ oz)
75 grams softened butter (2½ oz)
75 grams margarine (2½ oz)
2 eggs
75 grams fine granulated sugar (2½ oz)
2 tablespoons lemon juice
1½ teaspoons baking powder
1 teaspoon vanilla extract
Pinch of salt
Instructions
Preheat air fryer to 160°C (320°F) for 5 minutes.
In a bowl, beat butter, margarine, vanilla extract, and sugar with a mixer or whisk until light and creamy (about 5 minutes). Be careful not to overmix.
Add the eggs one at a time, beating well after each addition. Add the second egg when the first is well incorporated.
Then add the flour, baking powder, lemon juice and a pinch of salt. Mix well.
Lightly butter a cake pan with softened butter. Cut out a circle of parchment paper and place it on the bottom of the pan to prevent the cake from sticking.
Pour the batter into the pan and smooth the surface with a spatula.
Place the pan in the air fryer basket and insert the basket into the air fryer. Set the timer for 20-25 minutes and cook the cake until golden brown and cooked through.
Insert a bamboo skewer or toothpick into the center of the cake. It is ready when it comes out clean.
Let the cake cool in the pan for at least 5 minutes, then turn it out onto a wire rack to cool completely.
