What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Here’s everything you need:

• All-Purpose Flour: For the perfect base and crumbly topping.
• Granulated Sugar: Sweetens the crust and topping while balancing the tartness of the raspberries.
• Unsalted Butter: Softened—this is the secret to that rich, buttery flavor and melt-in-your-mouth texture.
• Brown Sugar: Adds depth and a hint of caramel to the streusel topping.
• Baking Powder: Helps give the crust a light, airy texture.
• Salt: Enhances the flavors without overpowering them.
• Egg: Helps bind the crust ingredients together.
• Fresh Raspberries: The star of the show! Their tartness is the perfect counterbalance to the sweetness of the crumb layers.
• Lemon Juice: Brightens the raspberry filling and enhances its fresh taste.
• Cornstarch: Thickens the raspberry filling so it doesn’t run all over.

If fresh raspberries aren’t available, you can use frozen ones—just make sure to thaw and drain them first. For a gluten-free option, swap the all-purpose flour with a gluten-free flour blend. And if you’re dairy-free, use a plant-based butter substitute.

Equipment Needed

• Mixing Bowls: You’ll need a couple of sizes for the crust, topping, and raspberry filling.
• Pastry Cutter or Fork: For blending the butter into the dry ingredients—though clean hands work just as well!
• 9×13-inch Baking Pan: The perfect size for these bars. If you don’t have this, two smaller pans can work in a pinch.
• Parchment Paper: Makes removal and cleanup a breeze.
• Spatula: For spreading the crust and filling evenly.

While a pastry cutter makes blending the streusel topping easier, I’ve also used two forks or even my fingertips. It’s all about what works for you!

Preparation Method

1. Preheat your oven to 375°F (190°C). Line a 9×13-inch baking pan with parchment paper.
2. In a large mixing bowl, whisk together 2 cups (250g) of all-purpose flour, 3/4 cup (150g) granulated sugar, 1/2 teaspoon baking powder, and a pinch of salt.
3. Add 3/4 cup (170g) unsalted butter, softened, and blend it into the dry ingredients using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
4. Mix in 1 large egg to bind the crust, then press two-thirds of the mixture into the prepared baking pan to form an even layer.
5. In another bowl, toss 3 cups (350g) fresh raspberries with 1/4 cup (50g) granulated sugar, 1 tablespoon lemon juice, and 2 tablespoons cornstarch until evenly coated.
6. Spread the raspberry mixture over the crust in an even layer.
7. Take the remaining crumb mixture and stir in 1/2 cup (100g) brown sugar. Sprinkle this over the raspberry filling, making sure to cover it completely.
8. Bake for 35-40 minutes or until the topping is golden brown and the filling is bubbling.
9. Remove from the oven and let cool completely before slicing into bars. (Trust me, it’s worth the wait!)

Cooking Tips & Techniques

Here are some tips to ensure your raspberry crumb bars turn out perfectly:

• Don’t Overmix: When blending the butter into the dry ingredients, stop once you see pea-sized crumbs. Overmixing can lead to a dense crust.
• Cool Completely: These bars need time to set before slicing—cutting them too early can make the filling runny.
• Use Fresh Lemon Juice: Bottled lemon juice doesn’t have the same brightness as fresh. It’s worth the extra squeeze!
• Substitute Smartly: If you’re out of fresh raspberries, frozen ones work just as well, but thaw and pat them dry first to avoid extra liquid.
• Experiment with Toppings: Add chopped nuts or oats to the streusel for extra texture—it’s a fun twist!

Variations & Adaptations

• Seasonal Swaps: Replace raspberries with fresh strawberries, blackberries, or even cherries depending on what’s in season.
• Gluten-Free Version: Use a 1-to-1 gluten-free flour blend to make these bars friendly for gluten-sensitive eaters.
• Vegan Option: Swap out the butter for a plant-based alternative and use a flaxseed egg in place of the regular egg.
• Add a Citrus Twist: Mix orange or lime zest into the crust for an extra pop of flavor.

Personally, I’ve tried these with a mix of raspberries and blueberries, and the result is just as delightful. Get creative and make it your own!

Serving & Storage Suggestions

These raspberry crumb bars are best served at room temperature or slightly chilled. Pair them with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent treat. For a refreshing twist, serve them with freshly brewed iced tea or a cup of coffee.

To store leftovers, keep the bars in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, wrap individual bars in plastic wrap and freeze them for up to 3 months. To reheat, simply thaw and pop them in the oven at 350°F (175°C) for about 5 minutes to refresh the crumb topping.
