Spay and line a 23cm spring form pan with baking paper.

Cream the butter and sugar in a stand mixer with a paddle attachment until pale and fluffy.

Add eggs, one by one and mix well and then add the vanilla essence and calvados and mix until all combined. 

Combine the flour, baking powder and salt and mix well then add to the butter mixture and stir gently until all combined.

Add the chopped apple and stir through.

Pour the mixture into the lined baking pan and place into the oven and cook for approx 25 – 30mins until a skewer inserted into the middle comes out clean.

Allow to cool slightly before removing from the pan.
