Place the blueberries into a small ramekin. Stir in the sugar and lemon juice. Set aside.
In a separate small bowl, mix together the flour, sugar, baking powder and salt. Add the milk and whisk until the batter is smooth.
Pour batter evenly over the blueberries. Bake for 25-28 minutes, until the topping is golden brown.
Enjoy warm with a scoop of vanilla ice cream, if desired.

Notes
Temperature Matters: Preheating your oven is crucial. Make sure your oven reaches the exact temperature before you start baking. I recommend using an oven thermometer which can help with this and ensure consistency in your results.
Baking Sheet Hack: Always place your ramekin on a baking sheet. Not only does it make it easier to take in and out of the oven, but it also catches any spills, saving you from a potential oven clean-up.
