Heat oven to 375°F and position a rack in the center.
Fit one dough round into a 9-inch pie plate; chill while you make the filling.
Cook the filling: In a saucepan, combine jam, strawberries, sugar, cornstarch, lemon juice, vanilla, and salt. Simmer, stirring, until glossy and slightly thick, 3–5 minutes. Cool 10 minutes.
Spread the filling into the chilled crust and smooth the surface.
Lay the second dough round over the top, trim excess, crimp edges to seal, and cut a few vents.
Brush the top crust with milk. Bake until deep golden and bubbling at the vents, 35–45 minutes.
Cool the pie on a rack for at least 1 hour, until the filling sets.
Whisk together powdered sugar, milk, and vanilla until smooth and pourable.
Drizzle the glaze over the cooled pie and shower with sprinkles. Let set 15 minutes before slicing.
Notes
For a toaster-pastry vibe, add 1/2 tsp almond extract to the glaze. Prefer a neater slice? Chill the glazed pie 30 minutes before cutting. Leftovers keep covered at room temperature for 1 day or refrigerated up to 3 days.This recipe is an original creation inspired by classic Strawberry Pop Tart Pie Recipe flavors.
