Delicious Blueberry Sour Cream Crumb Bars!

These lemon blueberry sour cream crumb bars are so good! The filling tastes like a light cheesecake with blueberries, which is awesome. But the best part, in my opinion, is the delicious crust. I am a crust-lover, for sure, and I definitely approve of this crust and plan to use it in the future with other yummy fillings too, like this homemade canned apple pie filling.

Mmm. Just looking at this photo is making me want to make these bars again right away. At the rate I’ve been using up blueberries this summer, maybe I need to plant a blueberry bush too!

Initial Preparation

Lining the baking dish with parchment paper makes it super easy to remove the finished bars from the pan, which makes them easier to cut into bars, which means you can start eating them a bit sooner. 😉

Reserve about 3/4 cup of the crumbly crust dough, then press the rest of the dough into the bottom of the prepared pan. I love that these measuring cups have a 2/3- and a 3/4-cup, along with the usual measurements, of course. Very convenient!

Getting it Ready for the Oven

Pour the easy sour cream mixture over the crust and you’re ready to top it off with the sugar-coated blueberries and remaining crust crumbles. That’s right, the blueberries are coated in sugar and fresh lemon juice. Genius.

Almost Done

There it is, all ready for the oven. Bake your lemon blueberry crumb bars until golden brown and not too jiggly in the center, then try to let them cool completely before you dig in. Serve with a refreshing glass of milk or coffee and enjoy!

Note: If you’d like, you can make these blueberry bars a day or two in advance, just store them in the refrigerator.
