Why you’ll love this recipe
- Made with basic ingredients
- The crust and topping are made from the mixture
- Filled with the fresh berries of your choice
- Flavored with vanilla and a touch of lemon
- Great for feeding a crowd
- Easy to slice and serve
Recipe overview
Crust and topping: A buttery, lemon-scented dough is used as both the crust and topping. Press half of it into the bottom of a pan, and reserve the rest for crumbling over the fruit.
Filling: Here’s where you can adapt this recipe to suit your taste (or whichever berries you have on hand). I like a mixture of strawberries, blueberries, raspberries, and blackberries (as pictured). You can absolutely use all of one berry or a mixture of berries. Cornstarch thickens the berry mixture and a touch of lemon complements the fresh flavors.
Recipe tips
- Line your pan with parchment paper or foil for easy removal
- When grating lemon zest, only use the yellow part of the skin, not the white pith
- Mix up the types of berries to suit your tastes
- Chill in the fridge before cutting, this makes for cleaner slices
- Plan to make these the day you are serving them (ideally) or up to 24 hours in advance.
- If you love a crumb topping, you should also try our Raspberry Crumble Cookies
Serving options
These bars can be served chilled or at room temperature. Serve as-is or top with ice cream or whipped cream.

Note July 2018: I changed this recipe just slightly. After a few comments requesting a larger quantity, I increased the recipe to make a 9×13 pan. I also added a bit of lemon to brighten the berry flavors.

Ingredients
Crust and Topping:
- 1 cup granulated sugar
- 1 teaspoon baking powder
- 3 cups all purpose flour
- ¼ teaspoon salt
- finely grated zest of 1 small lemon, optional, but so good!
- 1 cup cold unsalted butter, cut into cubes
- 1 large egg
- ½ teaspoon pure vanilla extract
Berry Filling:
- 4 ½ cups chopped fresh berries, see note
- ½ cup granulated sugar
- 4 teaspoons cornstarch
- juice of 1 small lemon
Instructions
Preheat oven to 375°F. Line a 9×13 pan with foil or parchment, and butter or spray with non-stick spray.
For the crust and topping:
Using a hand mixer or stand mixer fitted with the paddle attachment, combine granulated sugar, baking powder, flour, and salt. Add lemon zest, butter, egg, and vanilla. Beat on low speed until the butter is evenly distributed in small pieces and the mixture is crumbly.
Dump a little more than half of the mixture into the bottom of the prepared pan. Use your hand or the bottom of a measuring cup to evenly press the dough into the pan.
Filling:
Gently stir together all ingredients until well incorporated.
Spread the filling over the crust, then crumble the remaining dough over the top of the berries.
Bake for approximately 40-45 minutes, until the top is light golden brown and the fruit is bubbling. Transfer pan to a wire rack to cool completely. For the cleanest slices refrigerate before cutting.
Notes
I used a combination of strawberries, blackberries, blueberries, and raspberries. I chopped the strawberries, halved the large blackberries, and left the raspberries and blueberries whole.
These bars are best within one day of being made.

Have made these twice, once with fresh berries and today with frozen mixed from Costco. Have to say came out about the same! Awesome!!! The frozen ones I did NOT thaw but mixed with the 4 1/2 tsp cornstarch and let sit while I made the crust. I used half a lemon for the juice and baked about 46 minutes. Came out great, not runny.Reply

I make this frequently for my kids with whatever berries are in season (on sale), although I cut the sugar a bit without anyone noticing. I also do the bottom layer and then stir in some oats and cinnamon to the remaining dough for a slightly different crumble on top.Reply

Just wasted 4 and a half cups of fruits !!! Followed every step and it never did some sort of crust and just a a big mess of golden mush … doesnt work at all ……Reply
Allison
Hi, Chantel. Sorry to hear that. Many people have had success with this recipe so it should work as written. Did you make any changes to the ingredients?

I tried this the same as the directions say and it was delicious. Then i tried it with half the butter. I pressed 2/3 of the flour mixture on the bottom. I added a little extra lemon juice to the berries. Then I saved some of the berry juice and sprinkled the top layer. This replaced the missing butter. it was just as good.Reply

Can I freeze the bars?

Allison
Hi, Cathy. I haven’t tried it. I would assume so, but the crumb topping might soften a bit after thawing.
