Raspberry Crumble Bars: A Deliciously Easy Recipe for Your Next Dessert

Raspberry Crumble Bars are a delightful treat that perfectly balance sweet and tart flavors, making them an irresistible choice for dessert lovers. As I take a bite of these luscious bars, I am reminded of summer picnics and family gatherings where this recipe has been a staple for generations. The history of crumble bars dates back to the early 20th century, originating in the United Kingdom, where they were often made with seasonal fruits. Today, Raspberry Crumble Bars have become a beloved dessert across the globe, cherished for their buttery crumble topping and vibrant raspberry filling.

What I adore about Raspberry Crumble Bars is their incredible texture; the crunchy topping contrasts beautifully with the soft, juicy fruit beneath. They are not only delicious but also incredibly convenient to make, perfect for a quick snack or a sweet ending to any meal. Whether you’re baking for a special occasion or simply indulging in a personal treat, these bars are sure to impress. Join me as we dive into this delightful recipe that celebrates the wonderful flavors of raspberries!

Raspberry Crumble Bars this Recipe

Ingredients:

  • 1 cup all-purpose flour
  • 1 cup rolled oats
  • 1/2 cup brown sugar, packed
  • 1/2 cup granulated sugar
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, melted
  • 1 teaspoon vanilla extract
  • 2 cups fresh raspberries (or frozen, thawed and drained)
  • 1 tablespoon cornstarch
  • 1 tablespoon lemon juice
  • 1 tablespoon granulated sugar (for the raspberry filling)

Preparing the Crust and Topping

Let’s start by preparing the crust and crumble topping. This is the base of our delicious raspberry crumble bars.

  1. In a large mixing bowl, combine 1 cup of all-purpose flour, 1 cup of rolled oats, 1/2 cup of brown sugar, 1/2 cup of granulated sugar, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. Mix these dry ingredients together until they are well combined.
  2. Next, pour in 1/2 cup of melted unsalted butter and 1 teaspoon of vanilla extract. Stir the mixture with a spatula or wooden spoon until it forms a crumbly texture. You want it to be moist but still crumbly, so don’t overmix!
  3. Preheat your oven to 350°F (175°C) while you prepare the raspberry filling.

Preparing the Raspberry Filling

Now, let’s get to the star of the show: the raspberry filling. This part is super easy and adds a burst of flavor to our bars.

  1. In a medium bowl, add 2 cups of fresh raspberries. If you’re using frozen raspberries, make sure they are thawed and drained well to avoid excess moisture.
  2. Sprinkle 1 tablespoon of cornstarch over the raspberries. This will help thicken the filling as it bakes.
  3. Add 1 tablespoon of lemon juice and 1 tablespoon of granulated sugar to the raspberries. Gently toss everything together, being careful not to crush the berries too much. Set this mixture aside while we prepare the baking dish.

Assembling the Bars

Now that we have our crust and filling ready, it’s time to assemble everything into the baking dish.

  1. Line an 8×8 inch baking dish with parchment paper, leaving some overhang on the sides for easy removal later. This will make it easier to cut the bars once they are baked.
  2. Take about two-thirds of the crumb mixture and press it firmly into the bottom of the prepared baking dish. Make sure it’s evenly spread out and compacted.
  3. Next, pour the raspberry filling over the crust, spreading it out evenly with a spatula. This will ensure every bite has that delicious raspberry flavor.
  4. Finally, sprinkle the remaining crumb mixture over the top of the raspberry filling. Don’t worry if it’s not perfectly even; a little variation adds to the charm!

Baking the Raspberry Crumble Bars

We’re almost there! Now it’s time to bake our delicious raspberry crumble bars.

  1. Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the raspberry filling is bubbling slightly around the edges.
  2. Once baked, remove the dish from the oven and let it cool in the pan for about 10-15 minutes. This will help the filling set a bit more.
  3. After it has cooled slightly, use the parchment paper overhang to lift the bars out of the baking dish and onto a cutting board. Allow them to cool completely before cutting into squares.

Serving Suggestions

These raspberry crumble bars are perfect for any occasion! Here are a few serving suggestions to elevate your dessert experience:

  • Serve warm with a scoop of vanilla ice cream on top for a delightful dessert.
  • Dust with powdered sugar for a beautiful Raspberry Crumble Bars

    Conclusion:

    In summary, these Raspberry Crumble Bars are an absolute must-try for anyone who loves a delightful balance of sweet and tart flavors. The buttery crumble topping perfectly complements the juicy raspberry filling, making each bite a heavenly experience. Whether you’re looking for a delicious dessert to impress your friends at a gathering or a sweet treat to enjoy with your afternoon tea, these bars are sure to be a hit. For serving suggestions, I love to pair these Raspberry Crumble Bars with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent treat. You can also experiment with variations by substituting the raspberries with other fruits like blueberries, strawberries, or even a mix of berries for a colorful twist. If you’re feeling adventurous, try adding a sprinkle of lemon zest to the filling for a refreshing zing!
