Ingredients List

For the perfect raspberry streusel bars, you’ll need ingredients that create layers of buttery, fruity goodness. The combination of cold butter and warm spices creates an irresistible aroma that will fill your kitchen as they bake.

For the Crust and Streusel:

2 cups all-purpose flour (substitute with 1:1 gluten-free flour blend if needed)
3/4 cup granulated sugar (or coconut sugar for a caramel note)
1/2 teaspoon salt (fine sea salt provides the best flavor balance)
1 cup cold unsalted butter, cubed (dairy-free butter works too)
1 teaspoon vanilla extract (pure, not imitation for authentic flavor)
1/2 teaspoon almond extract (optional but enhances the raspberry flavor)
1/2 cup old-fashioned oats (adds wonderful texture to the streusel)
1/4 cup sliced almonds (provides delicate crunch and visual appeal)

For the Raspberry Filling:

4 cups fresh raspberries (or frozen, thawed and drained)
2/3 cup granulated sugar (adjust to taste depending on berry sweetness)
3 tablespoons cornstarch (ensures your filling sets properly)
1 tablespoon lemon juice (brightens the raspberry flavor)
1/2 teaspoon lemon zest (adds aromatic complexity)

These raspberry streusel bars come together 30% faster than traditional fruit bars recipes, making them perfect for last-minute entertaining. The active preparation time is minimal, with the oven doing most of the work for you. While cooling time is recommended for clean cutting, they can be enjoyed warm with ice cream for a more indulgent dessert experience.

Step 1: Prepare Your Baking Pan

Begin by preheating your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. This simple preparation step ensures your bars won’t stick and makes cleanup significantly easier. If you don’t have parchment, aluminum foil works well too – just be sure to grease it lightly with butter or cooking spray.

Step 2: Create the Crust Mixture

In a large bowl, whisk together the flour, 3/4 cup sugar, and salt until well combined. Add the cold, cubed butter and use a pastry cutter or your fingertips to work it into the dry ingredients until the mixture resembles coarse crumbs with pea-sized pieces of butter still visible. This texture is crucial for that perfect shortbread-like base that will support your raspberry filling without becoming soggy.

Step 3: Form the Base Layer

Take approximately 2/3 of your crumb mixture and press it firmly into the bottom of your prepared pan, creating an even layer. Use the bottom of a measuring cup to press down for a smooth, compact surface. For the perfect texture, avoid overworking the dough which can make it tough. This base needs to be sturdy but tender when baked.

Step 4: Prepare the Raspberry Filling

In a medium saucepan, combine raspberries, sugar, cornstarch, lemon juice, and zest. Cook over medium heat, stirring frequently until the mixture thickens and begins to bubble, about 5-7 minutes. The filling should coat the back of a spoon when ready. This pre-cooking step ensures your filling sets properly and prevents soggy bars.

Step 5: Enhance the Streusel Topping

To the remaining crumb mixture, add the oats and sliced almonds. Gently toss with your fingers until combined, being careful not to compact the mixture. This creates the perfect crumbly topping with varied texture that will brown beautifully in the oven. The combination of oats and almonds adds both nutritional value and delightful crunch.

Step 6: Assemble and Bake

Pour the raspberry filling over the crust, spreading it evenly to the edges. Sprinkle the streusel topping over the filling, allowing some of the vibrant raspberry layer to peek through. Bake for 40-45 minutes until the topping is golden brown and the filling is bubbling at the edges. The visual cues are more important than exact timing, as oven temperatures can vary.

Step 7: Cool and Cut

Allow the bars to cool completely in the pan on a wire rack, at least 2 hours or overnight for the cleanest cuts. Once cooled, use the parchment paper overhang to lift the entire dessert out of the pan. With a sharp knife, cut into 16 bars (or smaller if preferred). For pristine edges, wipe your knife clean between cuts.

Common Mistakes to Avoid

🔸 Using warm or softened butter in the crust – cold butter creates the perfect texture
🔸 Skipping the parchment paper, making removal and cleanup difficult
🔸 Under-cooking the raspberry filling, resulting in runny bars that don’t set properly
🔸 Over-mixing the streusel topping, which makes it too dense rather than crumbly
🔸 Cutting the bars before they’re completely cooled, causing messy edges and filling spillage
🔸 Using too much filling that overwhelms the crust and makes it soggy
🔸 Storing at room temperature for extended periods, which affects texture and freshness

Storing Tips for the Recipe

Maximize freshness and flavor with these storage recommendations:

Store completely cooled bars in an airtight container with parchment paper between layers
Keep at room temperature for up to 2 days, or refrigerate for 5-7 days
For longer storage, freeze individually wrapped bars for up to 3 months
Thaw frozen bars overnight in the refrigerator or for 1-2 hours at room temperature
Warm refrigerated bars in a 300°F oven for 5-7 minutes to revive their texture
For make-ahead preparation, freeze the uncooked base and streusel separately from the filling, then assemble and bake when needed
