Storage Information
- Refrigerator: Allow the bars to cool completely before cutting them. Once cut, store them in an airtight container in the refrigerator for up to 5 days.
- Freezer: Wrap the cut bars tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag or container. They’ll stay fresh in the freezer for up to 3 months. To serve them, simply thaw at room temperature or warm them up in the oven for a few minutes.
Can I use frozen blackberries instead of fresh?
Yes! No need to thaw, just use as you would fresh berries.
Can I use a different fruit for the filling?
Absolutely! You can easily swap the blackberries for raspberries, blueberries, or a mix of your favorite berries. Just keep in mind that the sweetness and tartness of the fruit may change the flavor slightly, so you’ll want to adjust the amount of sugar added accordingly.
Trish’s Tips
Fresh blackberries, a buttery crust & crumble, and hints of lemon combine to create these delicious Blackberry Crumb Bars. Here are a few tips for you to get the best results:
- For the best flaky, buttery crust, make sure the butter is cold and cut into small pieces before mixing it with the dry ingredients. This helps to create that nice crumbly topping.
- For a solid crust, make sure to press the mixture into the pan firmly. This helps create a firm, even layer that won’t fall apart once the bars are cut.
- Let the bars cool completely before cutting them. This allows the filling to set and makes the bars easier and cleaner to slice.

I have berries sitting in the fridge that I need to do something with. This is what they will be going in! Can’t wait to make this today!
Made this last night – so good! Buttery, lemony, and then the berry – Wow! Thanks – just one question though. My “crumbles” turned more into a dough when I added the egg – any suggestions on how to incorporate the eggs?
Hi Charlene, So glad you gave the recipe a try. Two ideas for keeping the crumble more crumbly… be careful not to mix the mixture too much after adding the egg, second (and likely the easiest) is to simply use your hands to break up the dough into smaller pieces, as desired.
These look gorgeous! Blackberries are often underrated so great to see them being celebrated!
Thanks so much Kelly! Agreed!
