"A detailed close-up of the texture of a soft, fluffy white vanilla cake with poppy seeds evenly scattered across its surface. The blueberries should be cooked into the batter, naturally integrated, with some slightly broken up, showing a deep blue color mixed with the soft, moist texture of the cake. There should be no visible crusts or bottoms, just the texture of the cake with the cooked blueberries and poppy seeds. The image should be full of detail, creating an appetizing and realistic feel, with a focus on the softness and juiciness of the cake."
