Pre-heat the oven to 175C (347F) fan-forced and great and line two loaf tins so that the paper extends over the long sides to make handles.
In a large bowl, use a fork to combine the flour, baking soda, baking powder, salt and cinnamon.
In a separate bowl, combine the butter, eggs, sugar, grated pear and vanilla.
Tip the we mixture into the flour mixture and stir it all together just until it is mixed in.
Divide the batter evenly between the two tins and bake the loaves for 60-70 minutes or until a cake tester inserted in the middle comes out clean.
Leave the bread to rest in the tins for 10 minutes and then transfer them to a wire rack to cool completely.
Slice up and serve.
