Make the pie filling by cooking blueberries, sugar, cornstarch, lemon juice, and cinnamon.
The sugar will start to melt and the blueberries will release their juice.
Press a lollipop stick into a cutout of pie dough and add a heaping teaspoon of pie filling to the middle.
Place the top on. Then crimp and seal the edges with a fork. Brush them with egg wash and bake.
Prepare a vanilla glaze while the blueberry mini pie pops are in the oven.
