Instructions
-
Make the Filling: In a medium saucepan, whisk together the sugar and cornstarch. Add the blueberries, 6 tablespoons of water, and lemon juice. Place over low heat, stirring constantly, until the mixture thickens and becomes jam-like, about 5-7 minutes. Remove from heat and set aside to cool slightly.
-
Make the Batter: In a large bowl, whisk together the flour, sugar, baking powder, and salt. Pour in the melted butter, ¾ cup water, and the beaten egg. Whisk until just combined into a smooth, thin batter—it will have a consistency similar to pancake batter.
-
Assemble the Pie: Pour the batter into your prepared pan. Carefully spoon the warm blueberry filling into the very center of the batter. Do not stir.
-
Bake: Bake for 30-40 minutes, or until the edges are deep golden brown and the top is set.
-
Cool Completely: This is the most important step! Let the pie cool completely in the pan on a wire rack. For the cleanest slices, cover and refrigerate it overnight. This allows the structure to set firmly.
-
Serve: Cut into slices and serve at room temperature or gently warmed. Top with a scoop of vanilla ice cream or a dollop of whipped cream. Enjoy!
