Wash the strawberries, drain them well and remove the stalks. Bake the mini cakes as indicated on the package.
Dice 4 strawberries and set them aside: blend the others with milk and sweeten to taste. Pour the smoothie into 4 glasses and serve it accompanied by the mini cakes sprinkled with strawberries.
NOTE For a thicker smoothie, you can add a banana or Greek yoghurt - plain strawberry or whatever flavour you prefer - to the strawberries.
