These Blueberry Pie Bars 🫐💙💜 are one of my all-time favorite blueberry dessert recipes! They're so much EASIER than blueberry pie because there's no pie crust to make. A true fan favorite with 800+ 5-star reviews! ⭐️

Preheat oven to 350F. Optionally, line an 8-inch square pan with nonstick aluminum foil and spray with cooking spray; set aside. Tip - In my experience, lining the pan will really help with cleanup and is recommended IF you use nonstick foil that you spray well. If you have other foil, or don't want to use it because you fear it will stick to the dessert, then omit the foil and just spray your pan well with cooking spray.
Make the Crust and Crumble Topping
In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
Add the sugars and whisk to combine.
And the flour, optional salt, and stir to combine. Mixture will be very dry and sandy with some larger, well-formed crumble pieces.
Set a heaping 3/4 cup crumble mixture aside.
Transfer remaining mixture to prepared pan, and using a spatula or your fingers, hard-pack the mixture to create an even, smooth, flat crust; set aside. See Tip in blog post about NOT overpacking. Press it down but you don't have to hard hard-pack it or the crust will bake up too hard to cut easily.
Make the Filling
In a medium bowl, add the egg, Greek yogurt, sugar, vanilla, and whisk to combine.
Add the flour and whisk to combine.
Evenly pour filling over the crust and jiggle pan to help distribute it or smooth it with a spatula; set aside.
Make the Blueberry Layer
In a separate medium mixing bowl, add all filling ingredients and toss to combine. If sugar hasn’t dissolved fully or still has crystals, that’s okay because it liquifies while baking.
Evenly distribute blueberry mixture over the filling.
Evenly sprinkle with the reserved heaping 3/4 cup crust mixture. Before sprinkling, I squeeze the mixture in my palm to encourage bigger crumble pieces to form.
Bake the Bars
Bake for about 60 minutes, or until edges are bubbling quite vigorously and there’s some bubbling in the center. Crumble topping should appear set and very pale golden.*
Place pan on a wire rack and allow bars to cool for at least 1 to 2 hours (overnight is even better) before slicing and serving. If you try to slice bars before they’ve cooled completely, they’ll be extremely messy and could fall apart. Bars will keep airtight at room temperature for up to 1 week, in the fridge for up to 10 days (they’re good slightly chilled if you like chilled pie), or in the freezer for up to 6 months.
