Preheat the oven to 350 degrees Fahrenheit.
Open the tin of peaches and retain the juice in a separate bowl.
Arrange the peaches along the bottom of a square baking til or small casserole dish.
Add the butter to a large bowl or stand mixer and mix until soft.
Add the sugar and mix further until light and fluffy.
Crack the egg into the mixture and mix quickly until well combine and light once again.
Add the flour, cayenne pepper powder, cinnamon, and baking powder to the mixture and then fold.
Add a splash of the peach juice until the sponge reached a thick but smooth consistency.
Pour the mixture over the peaches and smooth the surface.
Bake in the centre of the preheated oven for 40-45 minutes or until a toothpick comes out of the center clean.
Allow to cool for ten minutes then serve with cream or ice cream.
