In a mixing bowl or stand mixer, add the 4 whole eggs and the zest of half a lemon. Mix well.

Add the sugar and beat for a few minutes until light and fluffy.

Add the mascarpone and mix until smooth.

Gradually add the sifted flour and baking powder, mixing as you go. While mixing, cut your peaches.

Cut 3 peaches into cubes.

Gently fold the peach cubes into the batter.

Grease and flour a cake pan.

Slice the remaining 2 peaches and arrange the slices on top, slightly overlapping.

Sprinkle with vanilla sugar. Bake at 350°F (180°C) for 46 minutes.

Melt a little peach or apricot jam in the microwave, or use your favorite jam. Brush the warm cake with the melted jam, then sprinkle with powdered sugar. Let cool. It’s even better the next day. Enjoy!
