Take a mixing bowl and beat butter, margarine, vanilla extract, and sugar with a mixer or whisk until light and creamy this takes about 5 minutes. Be careful to not overmix

Step 4

Then add the flour, baking powder, lemon juice, and a pinch of salt. Mix thoroughly

Take some soft butter to butter the cake pan. Cut a circle from parchment paper and put it in the cake pan so the cake won’t stick to the pan

Step 6

Put the cake pan in the fryer basket and slide the basket into the Air Fryer. Set the timer to 20-25 minutes and bake the cake until it is done and brown.

Take a bamboo skewer or toothpick and insert it into the center of the cake. It is done when it comes out clean
