Buttery crumb bars filled with mixed berries and a touch of lemon. This simple recipe uses the same mixture for the the crust and topping.
Hello, friends! I hope you are enjoying a beautiful summer weekend. I am stopping in to make a few suggestions for your 4th of July menu. Up first: Berry Crumble Bars!
I first made these Berry Crumble Bars several years ago. To be honest, they fell off my radar until I made them again recently for my daughter’s birthday. I was immediately reminded how great they are, and I knew I needed to bring them to your attention right away. And if you love a crumb topping, you should also try our Raspberry Crumble Cookies.
Bonus: They are the perfect dessert for your 4th of July festivities. The colors are patriotic, every bite is bursting with summer flavors, and you can pack them up and take them wherever you are headed (pool, beach, lake, BBQ, etc).
Berry Crumble Bars
- 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.
- Berries! 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 mix of 2 or 3. Cornstarch thickens the berry mixture and a touch of lemon compliments the fresh flavors.
Tips for Berry Crumble Bars
- 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 berries to suit your tastes.
- Chill these completely in the fridge before cutting, as this makes for cleaner slices.
- Leftovers? Highly unlikely, but if you do have a few bars leftover, put them in the freezer and enjoy them another time.
These bars really are the perfect summer dessert. We like them straight from the fridge or at room temperature. And maybe, just maybe, you could justify eating one for breakfast. Fruit = breakfast food, right?
If you really want to take these over the top, you can serve them with ice cream or whipped cream. I happened to have vanilla blackberry swirl ice cream in my freezer, and it was the amazing on these bars. Vanilla ice cream or strawberry ice cream would also be great.
Have a safe and happy 4th of July! Check out the list below for more summer recipe inspiration.

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.

Mixed Berry Crumble Bars
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 9x13 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 minutes, until the top is light golden brown. Transfer pan to rack to cool, before cutting into squares. I have also refrigerated these, after cooling to room temp.

I chose this recipe for it’s simplicity, and used it with some helpers to convert a few frozen pounds of last summer’s harvest (I have a lot of berries) to dessert squares for an impromptu community gathering. After the first batch…which was a bit soggy-bottomed…we added the same amount of flour as cornstarch, and also tried hard to ensure the fruit mix was mostly dry-ish. Much better. If you’re using frozen fruit, we advise to err on the side of dry.
I also added oats and b. sugar to the topping, who can resist, and broiled it after baking, just a few minutes for caramelization. The recipe was great, it all got eaten!
