Mix flour, baking powder and baking soda together in a medium bowl with a pinch of salt. In a second bigger bowl whisk together (you can use a hand mixer) sugar, eggs, yoghurt, oil, vanilla extract and cinnamon until all ingredients combine into a smooth batter.
While still whisking the butter add flour mixture gradually until combined. Pour the butter into the cake form laid with parchment paper. I used a 32x22, 5 cm deep cake tin. Align the top of the cake, place pieces of the cantaloupe on top of the cake.
Bake for around 30 to 40 min in 190C. Let it cool before serving, Dust with icing sugar and enjoy.
