Gather Your Ingredients
Before you start, it’s important to gather all your ingredients to make the cooking process smoother. For this recipe, you will need:
- 1 ½ cups quick oats
- 1 ½ cups all-purpose flour
- 1 cup brown sugar, lightly packed
- 1 cup melted butter
- 1 ½ teaspoons cinnamon
- 1 teaspoon vanilla extract
- ½ teaspoon baking powder
- ½ teaspoon sea salt
- 2 ½ cups mixed berries (fresh or thawed if frozen)
- Juice of ½ lemon
- 1 teaspoon corn starch
- 3 tablespoons sugar (consider adjusting based on berry sweetness)
Having everything on hand will keep you organized and ready to whip up these delightful bars!
Prepare the Berry Filling
Now, let’s create that delicious berry filling! In a mixing bowl, combine the mixed berries, sugar, lemon juice, and corn starch. Gently mix them together to avoid breaking the berries. Let this mixture sit while you prepare the crust. This allows the flavors to meld and the juices to develop, which will make for a rich filling.
Mix the Dry Ingredients
In another bowl, it’s time to combine the dry ingredients. Mix together your oats, flour, brown sugar, cinnamon, baking powder, and sea salt. Whisk these together until they are well-combined. The mixture should be somewhat crumbly, which is just what you want for those mixed berry crumble bars.
Combine Wet Ingredients With Dry
Now that you have your dry ingredients mixed, it’s time to add the wet ingredients. Pour in the melted butter and vanilla extract, mixing until everything is just combined. Don’t worry if it looks a bit crumbly; that’s perfect!
Create the Crust and Topping
Grab an 8x8 inch baking dish lined with parchment paper. Press about two-thirds of your oat mixture firmly into the bottom of the dish to create the crust. This solid base is essential for holding the bars together.
Assemble and Bake the Bars
Now it’s time to layer! Spoon the berry mixture over your crust, spreading it evenly. Then, sprinkle the remaining oat mixture over the top. Place your baking dish in a preheated oven at 350°F and bake for about 28-32 minutes, or until the berries bubble and the top is a lovely golden brown.
Once baked, let the bars cool completely before cutting. This way, they’ll hold their shape when you slice them up. Enjoy your homemade mixed berry crumble bars as a sweet treat, snack, or dessert!

Baking Notes for Mixed Berry Crumble Bars
Tips for Achieving the Perfect Crumble Texture
To get that delightful crumbly texture for your mixed berry crumble bars, ensure you're using quick oats instead of rolled oats. Quick oats absorb moisture more effectively, maintaining that ideal crispness. Additionally, when mixing your dry ingredients, don’t overwork the butter; you want it just combined for those irresistible crumble pockets!
How to Avoid a Soggy Bottom
A soggy bottom can be a baking nightmare! To prevent this, make sure to press the base layer firmly into the pan, allowing it to create a solid foundation. Consider baking the crust for 10 minutes before adding your mixed berry filling; this pre-baking step sets the crust, helping it resist moisture from the berries. And remember, letting the bars cool completely before cutting allows the filling to set nicely, ensuring your bars stay firm and delicious!

Serving suggestions for Mixed Berry Crumble Bars
Pairing with ice cream or yogurt
One of the best ways to elevate your mixed berry crumble bars is by serving them with a scoop of vanilla ice cream or a dollop of whipped yogurt. The creamy texture of the ice cream perfectly complements the warm, fruity filling, creating a delightful contrast that your taste buds will love. Looking for a lighter option? Greek yogurt adds a tangy twist and packs extra protein, making it a great post-workout snack!
Creative serving ideas: parfaits and snacks
Think outside the box! Crumble up your mixed berry bars and layer them in a glass with yogurt and granola for a delicious parfait. This not only makes a stunning presentation but also turns your bars into a satisfying snack or breakfast option. You can also pack pieces of the bars in lunchboxes for a sweet treat on the go.
