Is there anything better than berries in the summer? Oregon Blackberries are one of my all time favorite berries – give me all things Blackberry! I love that they are picked at the peak of ripeness for better tasting berries. Oregon Blackberries are the best in the summertime. They taste great in bars, pies, and even salads. Blackberries really make it feel like summer.
I love that Oregon Blackberries are grown by local families on multi-generational farms. Did you know Oregon is the perfect climate for growing blackberries? We have the optimal soil, air, water, and climate. Fresh or frozen, Oregon Blackberries are delicious. Frozen blackberries have a lot of benefits – they are flash frozen within 24 hours of being picked so all nutrients are locked in, they are available year round, and they keep well for a long time in the freezer. And blackberries are packed with antioxidants and nutrients like vitamin C, fiber, and vitamin A. To learn more about Oregon Berries visit https://www.oregon-berries.com/.
If you want some blackberries in your summer baking, you’ll love these Cinnamon Blackberry Crumb Bars because they are not only delicious, but they are easy to make with mostly ingredients you already have on hand. Really really easy. They have the flavor of a summer berry pie with the ease of a cookie bars!
After making a simple cinnamon crumb mixture with mostly pantry ingredients, you will press part of the mixture into the bottom of a 9×13” pan. Then toss blackberries (fresh or frozen!) with sugar, lemon juice, and a little cornstarch and pour them on top. Add the remaining crumb topping and bake. That’s it! No parboiling, no separate crumb topping recipe – it’s just 2 components, and can be in the oven in under 10 minutes.
I love that these Cinnamon Blackberry Crumb Bars taste like berry pie but they are so much easier. And they have crumb topping! Crumb topping makes everything better.

Cinnamon Blackberry Crumb Bars
Ingredients
Base & Crumb Mixture
- 3 cups all purpose flour
- 1/3 cup brown sugar
- 1 cup white sugar
- 1 teaspoon cinnamon
- 1/2 teaspoon nutmeg
- 1/2 teaspoon salt
- 1 teaspoon baking powder
- 1 cup unsalted butter, melted (2 sticks)
- 1 egg, beaten
Blackberry Filling
- 5 cups Oregon blackberries
- 1/4 cup fresh lemon juice
- 2 tablespoons cornstarch
- 1 cup white sugar
Instructions
- Preheat oven to 350 degrees F. Prepare a 9”x13” pan. Line the pan with parchment paper and spray with nonstick cooking spray.
- Start by preparing the berry mixture. In a large bowl combine blackberries, sugar, cornstarch, and lemon juice. Mix well and set aside to let sugar work into berries.
- In a separate mixing bowl combine flour, white sugar, brown sugar, cinnamon, nutmeg, salt, and baking powder. Mix until well combined.
- Slowly add melted butter and mix with a fork to incorporate. Then add in beaten egg and mix to incorporate.
- Press ⅔ of the crumb mixture into the bottom of the prepared pan. Then pour the blackberry mixture over the top (include any juices in the bottom of the bowl). Spread the berries evenly over the pan, then top with remaining ⅓ of crumb mixture.
- Place into preheated oven and bake for 50-60 minutes until berries are bubbling and thickened. (If the top starts getting too browned before the berries are bubbling, you can place a sheet of aluminum foil over the top until it finishes baking).
- Once berries are bubbling all over (including the center) and look thickened, remove from the oven. Let them rest for a little before serving, about 30-40 minutes to set. You can also chill before serving.Cut into squares and serve. Enjoy!
