This is a variation of the delicious olive oil cake we make at Petraia for our breakfast table. In May and June when our roses are at their peak we use fresh roses. The rest of the year we use dehydrated petals. It is an easy one bowl cake and a good keeper too.
Preheat the oven to 165 degrees C (325 F). Lightly grease and flour a loaf pan or an 9 inch cake tin with removable bottom. Turn the pan upside down and tap out any excess flour.
Combine all the ingredients together in the mixing bowl of a stand mixer fitted with the paddle attacment. Mix until everything comes together. Transfer the batter to the baking tin and bake until a cake tester comes out clean, about 1 hour. Cool on a rack.
