Preheat the oven to 180°C. Grease and line an 18cm² cake tin.
Sift together the flour, salt, baking soda and baking powder.
In a processor, cream the butter and sugar. Beat the eggs and add to the mixture gradually, processing between each addition. Add the Apple Pear Cinnamon pouches and mix well.
Add the flour mixture to the processor and blend together. Pour batter into tin and bake for 30 minutes. Lower the temperature to 160°C and bake for another 15-20 minutes until golden brown and firm to the touch.
Allow to cool for 10 minutes then remove from tin and finish cooling on a wire rack.
