Ingredients for Raspberry Crumble Bars
The perfect raspberry filling
When it comes to the raspberry crumble bars, the filling is where the magic happens! You’ll need two 12-ounce bags of frozen raspberries—these work beautifully as they provide a consistent flavor year-round. Sweeten them with ½ cup of granulated sugar, adjusting based on how tart your berries are. Don’t forget to add 2 tablespoons of flour and 1 tablespoon of cornstarch to help thicken that delicious mixture. The juice of one lemon will round it out with a zesty freshness.
Essential ingredients for the crumble layer
The crumble layer is key to achieving that perfect texture. Gather 3 cups of rolled oats for the chewiness, combined with 3 cups of flour for structure and 2 cups of brown sugar (loosely packed) to provide the right amount of sweetness. You’ll also need 1 teaspoon of baking powder, 1 ½ cups of melted butter (preferably salted), and ½ teaspoon of salt to balance out the flavors.
Are there any substitutions you can make?
Of course! If you’re out of frozen raspberries, feel free to swap in other berries like blueberries or blackberries. For the crumble, you can replace part of the oats with almond flour or coconut flour for a gluten-free version. Use coconut oil instead of butter if you want a dairy-free option. Always remember that cooking is about customizing it to your taste, so make it your own!
Step-by-step preparation of Raspberry Crumble Bars
Making delightful raspberry crumble bars is an enjoyable way to spend some time in the kitchen, and the results are worth every minute spent preparing them. Let’s dive into the steps for crafting these delicious treats, ensuring you have everything you need along the way.
Prepare your raspberries
Start by preheating your oven to 350 degrees Fahrenheit. Grab those frozen raspberries and place them in a large colander. To help thaw and soften them, run warm water over the raspberries for about a minute. This makes it easier to mix them into your filling later. Allow them to drain for about an hour; you'll want them thoroughly drained so that your bars don't end up too soggy. After they've drained, combine your raspberries with granulated sugar, flour, cornstarch, and the juice of one lemon in a bowl. This mixture adds a delightful sweetness and tang, enhancing the natural flavor of the berries.
Create the delightfully soft crumble base
Next, it’s time to whip up the crumble base. In a separate bowl, mix together rolled oats, flour, brown sugar, baking powder, melted butter, and salt. This creates a soft, crumbly mixture that will form the foundation of your bars. Press about two-thirds of this mixture into the bottom of a 9×13 pan lined with parchment paper. This helps with easy removal later. Bake this layer for 10 minutes to set it slightly—just enough to create a solid base for your luscious raspberry filling.
Bake the base to perfection
After baking for 10 minutes, remove the base from the oven. This initial baking step is crucial, as it prevents the base from becoming overly soggy when the raspberry layer is added. Allow it to cool slightly while you continue with the recipe.
Layer the raspberry filling
Now it’s time to layer on your raspberry filling! Spread the raspberry mixture evenly over the baked crumb base. Make sure to cover it generously—each bite deserves that burst of fruitiness!
Add the crumble topping and bake again
Finally, sprinkle the remaining crumble mixture over the raspberry filling, evenly distributing it to ensure a nice, crispy topping. Return the pan to the oven and bake for another 25-30 minutes until the top is golden brown and the filling is bubbling. When they come out of the oven, resist the temptation to dig in immediately—let the bars cool and set for a few hours. This makes for easier cutting later on. If you can't wait, feel free to enjoy them warm, akin to a comforting fruit crisp.
With these steps, you’re well on your way to creating your own raspberry crumble bars. Enjoy this tasty treat as a snack, dessert, or even breakfast option paired with a nice cup of tea! For further inspiration, check out some berry-inspired recipes online for even more fruity goodness!

Variations on Raspberry Crumble Bars
Berry Medley Crumble Bars
Why stick to just raspberries when you can create a delightful medley? Incorporating mixed berries like blueberries, blackberries, or even strawberries can elevate your crumble bars to another level. Try using equal parts of frozen mixed berries in place of raspberries for a colorful twist. The combination brings an exciting burst of flavors that will leave your taste buds dancing. For a deeper flavor, consider adding a touch of cinnamon to the crumble layer or drizzling some honey on top after baking.
Gluten-Free Raspberry Crumble Bars
Craving those delicious raspberry crumble bars but need a gluten-free option? No problem! Substitute the regular flour with a 1:1 gluten-free baking blend. Oats are often gluten-free but double-check the packaging to ensure there’s no cross-contamination. You can enhance the texture by adding ground almonds or coconut flour to the crumble mixture. These substitutions will not only maintain the delightfully soft texture but also add a nutty flavor to your bars.
