Preheat your oven to 400°F (200°C).

Butter four oven-proof dessert dishes lightly and sprinkle each dish with 4 teaspoons of castor sugar.

Divide ½ cup of fresh blueberries among each dish.

Mix cream cheese, remaining castor sugar, flour, vanilla extract, and one egg until smooth in a stand mixer.

Incorporate the remaining two eggs into the mixture and gradually add whole milk.

Pour the batter over the blueberries, filling dishes about an inch from the top.

Sprinkle lemon zest over the top of the batter and place the dishes on a baking sheet.

Bake for 20 minutes or until golden brown and a toothpick comes out clean.

Cool slightly before dusting with confectioners’ sugar and serving warm.
