Berry Oatmeal Crumble Bars
Berry oatmeal crumble bars are the perfect use for fresh summer berries! A crispy oatmeal shell surrounding a sweet homemade berry jam – delicious with blueberries, blackberries, raspberries, or strawberries.
Ingredients:
- 3 cups fresh berries of choices
- 1 tablespoon lemon juice
- 1/2 cup sugar
- 2 tablespoons cornstarch
- 1 1/2 cups all purpose flour
- 1 1/2 cups rolled oats
- 1 cup brown sugar
- 3/4 cup butter, softened and cut into large chunks
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
Directions:
- To prepare filling, stir together berries and lemon juice in a medium saucepan. Cook over medium heat until fruit is tender, about 15 minutes.
- In a small bowl, whisk together sugar and cornstarch. Stir into fruit mixture. Continue cooking until mixture comes to a boil. Boil for 1-2 minutes until thick. Remove from heat.
- Preheat oven to 350F and lightly grease a 9”x13” baking pan.
- In a large mixing bowl, combine flour, oats, brown sugar, butter, baking soda, salt, and vanilla extract. Cut ingredients together with pastry blender or two knives until mixture resembles coarse crumbs, or pulse for several seconds in a food processor. Set aside 1 1/2 cups of mixture in a medium bowl.
- Pour remaining crumb mixture into the bottom of the dish, spread evenly, and pat down. Place filling in dollops over crust and carefully spread to cover entire surface.
- Squeeze reserved crumb mixture into large clumps with fingers and sprinkle evenly over the top of the fruit filling.
- Bake until golden brown, about 30 to 35 minutes. Cool completely before slicing.

I love bringing crumble bars to summer picnics! They’re such a great portable dessert, and everyone always devours them. I’ll have to try them with your fresh berry filling! What a great way to celebrate berry season.
I could also eat them by the pound. These bars look good enough to sell in a high end coffee shop 😉
It’s funny, I used to have the berry overload problem, and then I had a son who is OBSESSED with them. Literally almost never turns down a berry. So now if I want to use them for anything besides his snacks, I need to purchase in truly mass quantities. I may squirrel some away in hiding, though, to make these bars next week, because they look INCREDIBLE!
My father’s birthday is coming up and his favorite breakfast treat is oatmeal bars. These look just perfectly soft. YUM
they look so scrumptious and I’m thinking they’ll be amazing school snacks easy to make ahead too. if I don’t have rolled oats handy, will quick oats be ok? thanks for this recipe
Yes, you can use quick oats, too!
