Preheat oven to 200 C (390 F) and line a baking tray with baking paper.
Puree melon to get 1 cup (I used about 1/3 of a melon).
Mix melon puree and egg together in a bowl.
Add flour and mix until combined.
Drop tablespoon amounts of the mixture onto the prepared baking tray, evenly spaced.
Bake for about 12 minutes, until top just starts to brown.
