Instructions: 1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
2. Prepare the Cake Batter: Gradually mix in the flour mixture, alternating with the milk until well combined. Spread the batter evenly into the prepared cake pan.
3. Make the Blueberry Filling: In a saucepan, combine blueberries, sugar, lemon juice, cornstarch, and water.Cook over medium heat, stirring constantly until the mixture thickens and the blueberries start to burst, about 5-7 minutes.
4. Assemble the Cake: Pour the blueberry filling over the cake batter in the pan, spreading it out evenly.
5. Bake the Cake: Place the cake pan in the preheated oven and bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
6. Serve: Slice and serve the blueberry pie cake, optionally with a dollop of whipped cream or a scoop of vanilla ice cream.
