Heat the oven to 170°C/340°F.

Prepare a 24 cm/9.5 inches round cake pan, grease in with butter and layer with baking paper.

In a food processor or blender, blend the shaved almonds for a few seconds until you get flour-like clumps.

In a large bowl, beat butter, sugar and zest together until light and fluffy. Add eggs, one at a time, beating until well combined.Add ground almonds, flour, baking powder, vanilla and lemon juice. Mix until combined.

Pour the batter into the prepared pan and smooth the surface. Top with peaches. Bake for 50-55 minutes or until a skewer inserted comes out clean.

Cool on a rack. Dust with powdered sugar. Enjoy!
