Raspberry Streusel Bars Ingredients
Here’s everything you need to whip up these delightful Raspberry Streusel Bars:
For the Filling
• Frozen Raspberries – Provides the sweet, tangy filling; if using fresh, add raspberry jam for thickness.
• Granulated Sugar – Balances the tartness of the raspberries; no direct substitution recommended.
• All-Purpose Flour – Aids in thickening the raspberry filling; unbleached flour is preferred.
• Cornstarch – Helps to stabilize the filling; can be omitted if necessary, but results may vary.
• Lemon Juice – Adds brightness and enhances raspberry flavor; always use freshly squeezed for the best results.
For the Streusel
• Old Fashioned Oats – Create the streusel base and topping, adding texture; quick oats may work but will alter the texture.
• Brown Sugar – Provides sweetness and moisture for the streusel; white sugar can be used, but it will change the flavor slightly.
• Baking Powder – Essential for desired texture, helping the streusel to rise while baking.
• Unsalted Butter – Provides richness to the streusel; margarine may work, but the fresh flavor will differ.
• Sea Salt – Enhances overall flavors, balancing sweetness; fine sea salt is recommended.
Step‑by‑Step Instructions for Raspberry Streusel Bars
Step 1: Prep Raspberries
Start by thawing 2 cups of frozen raspberries in a bowl, which may take about 10-15 minutes. Once thawed, carefully drain and pat them dry with paper towels to remove excess moisture. This step is crucial to prevent a watery filling in your Raspberry Streusel Bars. Set the prepared raspberries aside while you mix the filling.
Step 2: Mix Filling
In a medium bowl, combine the dried raspberries with ⅓ cup granulated sugar, 2 tablespoons of all-purpose flour, 1 tablespoon of cornstarch, and 2 teaspoons of freshly squeezed lemon juice. Gently fold the ingredients together until well coated. The sugar should begin to dissolve, creating a syrupy texture that enhances the sweet-tart flavor of the filling. Set this aside to allow the flavors to meld.
Step 3: Prepare Streusel
Preheat your oven to 350°F (175°C) and grab an 8x8-inch baking pan, lining it with parchment paper for easy removal later. In a large mixing bowl, stir together 1 cup of old-fashioned oats, 1 cup of all-purpose flour, ½ cup brown sugar, 1 teaspoon baking powder, and ¼ teaspoon sea salt. Pour in ½ cup melted unsalted butter and mix until clumpy, reserving ½ cup of this streusel mixture for the topping.
Step 4: Bake Base
Take the remaining streusel mixture and pressed it firmly into the prepared baking pan to form a crust. Bake in the preheated oven for 10-12 minutes, or until just set and lightly golden. This pre-baking step ensures your bottom layer of the Raspberry Streusel Bars has a solid foundation and won’t turn soggy when the filling is added.
Step 5: Assemble Bars
Once the base has baked and is still warm, carefully pour the raspberry filling over the top, spreading it evenly. Next, sprinkle the reserved streusel mixture over the raspberry layer, creating a crunchy topping that will bake to perfection. Return the assembled bars to the oven and bake for an additional 25-30 minutes, or until the top is golden brown and the filling is bubbly.
Step 6: Cool & Chill
After baking, remove the Raspberry Streusel Bars from the oven and let them cool in the pan for about 30 minutes. Once cooled, place the bars in the refrigerator for at least 2 hours to allow the filling to set properly. This chilling step is vital for clean, beautiful slices when you're ready to serve them at your next gathering.

What should I do if my filling turns out too watery?
No worries! If your raspberry filling is too watery, it might be due to excess moisture from the thawed raspberries. To fix this, make sure you fully thaw and pat them dry before mixing. You can also add a little extra cornstarch to help stabilize the filling. Just mix it in with the raspberries, sugar, and flour.
Are Raspberry Streusel Bars suitable for those with allergies?
