Y’all I keep my blueberry crumble bars on repeat during the spring and summer. They taste better than pie and are easier to make too. I use fresh blueberries. Then I make a simple buttery crumble for the top and bottom of the bars. It’s just too good boos.

How to Make Blueberry Crumble Bars
- Combine the flour, sugar, baking powder, and salt in a bowl and whisk together.
- Add the cold butter and cut it into the flour using two forks or a pastry cutter.
- Add the egg yolk and cold water and slowly mix it in.
PRO TIP: Don’t worry if the dough seems really crumbly. It should be!
- Press half of the crumble mixture into your prepared pan.
- Stir together the blueberries, lime juice, flour, sugar, cinnamon, and vanilla in a mixing bowl until combined.
- Spread the blueberry filling on top of the bottom crust in the pan.
- Sprinkle the remaining crumble topping over the top of the blueberry filling.

Notes
How to Store
Since these bars contain fruit, I think it’s a good idea to store them in the refrigerator, especially in the hot Summer. Not only does storing them in a cool spot help keep the berries fresh, but it also allows them to keep shape and last longer. Leftover bars will last for up to 3 days in an airtight container in the fridge. Another option is to store these in the freezer to extend their shelf life for up to three months. They will thaw quickly on the counter at room temperature for an hour. They’re great straight from the fridge, but my favorite way to enjoy them is by warming them up in the microwave for a few seconds. Even better, crumble the warm bar over vanilla ice cream for even more amazingness! I love to do this to other bars like my Peach Crumb Bars and Apple Bars.Nutrition
Recipe Tips
- Don’t thaw frozen blueberries if using them. Just roll them in a little flour so it soaks up some of the additional wetness as it bakes in the oven.
- Use cold butter and cold water for the crust! This is what makes your crumble crust light, flaky, and crumbly.
- Blueberry crumb bars are best served warm and even better with a scoop of vanilla ice cream!
- Allow the bars to cool to room temperature before cutting them. This allows them to set so they don’t fall apart when cut.
Recipe Help
Sure you can use sliced strawberries, blackberries, raspberries or even a mixture!
Yep! Use a 9 x 13 baking pan instead of the square to make them all in one pan.

I’m a huge fan of crumble. It’s easy, sure, but it’s also more delicious (I think) than traditional crust. I can never stop eating anything with crumble! And this looks perfect.
Agreed! There is something about a crumble that makes me weak.
