Easy blueberry pie bars have a soft cake crust, juicy blueberry pie filling, and sweet crumble topping. Everything you love about blueberry pie, but in a dessert bar.
Preheat the oven to 350°F. Grease a 9x13 baking dish or line it with parchment paper.
In a medium mixing bowl, beat together the cake mix, eggs, and vegetable oil. Beat with a hand (or stand) mixer until combined. The mixture will be thick and crumbly.
Remove half of the mixture and set it aside. Press the remaining dough into the bottom of the prepared baking dish.
Bake for 15 minutes, then remove from the oven.
Spread blueberry pie filling over the top of the baked base. One can of pie filling will cover the pie bars nicely.
Sprinkle the reserved dough in clumps over the top of the blueberry pie filling.
Return the baking dish to the oven and bake for 15 to 20 minutes longer until the top of the bars is just beginning to brown.
Cool bars completely.
Whisk together powdered sugar and enough cream to make a sugar glaze. Drizzle over the top of the cooled bars.
