Prepare a pie crust using your favorite recipe then chill it in the fridge while you get the other ingredients ready.
Preheat oven to 425 degrees F.
In a small mixing bowl, combine the blueberries, honey, and cornstarch. Mix well.
In another small bowl, combine the flour and granulated sugar. Pour in the melted butter and mix well using a fork or your fingers until crumbly.
Remove the pie crust from the fridge and roll into about a 12-inch circle, or the correct size to fit your tart pan. Press the dough gently in the pan. Trim off any excess dough so it's even with the top of the pan.
Pour the blueberry mixture in the prepared pan and spread out evenly.
Sprinkle the crumble mixture evenly on top of the blueberry filling.
Bake for about 40 minutes, or until the crust is golden brown and the center of the blueberry filling is bubbling.
Cool on a wire rack before serving.
