Preheat your oven to 350°F. Grease an 8x8 square cake pan or line it with parchment paper
To a food processor, mini chopper, or blender add in your drained peaches and blend/chop until very finely diced
To a mixing bowl add in peaches + all remaining ingredients and mix until just combined
Pour the batter into the prepared cake pan and spread it out evenly
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean
Allow the cake to cool in the pan for a few minutes, then transfer it to a wire rack to cool completely
Slice only once cooled
Serve and enjoy!
