Step‑by‑Step Instructions for Raspberry Streusel Bars
Step 1: Prepare Raspberries
Begin by thawing the frozen raspberries in a bowl of cold water for about 10 minutes. Once thawed, drain them thoroughly and pat dry with a paper towel to avoid excess moisture. In a mixing bowl, combine the raspberries with sugar, flour, cornstarch, and lemon juice, gently folding to coat the berries without mashing them.
Step 2: Preheat Oven
Set your oven to preheat at 350°F (175°C). While the oven is warming up, take an 8×8-inch baking pan and line it with parchment paper, allowing some overhang for easy removal later. This will help create a perfectly baked Raspberry Streusel Bars with a crisp bottom and easy serving.
Step 3: Make Streusel
In a mixing bowl, combine old-fashioned oats, flour, light brown sugar, baking powder, and sea salt. Melt butter in the microwave or over low heat and pour it into the dry ingredients, mixing until the mixture becomes clumpy. Be sure to reserve half a cup of this streusel mixture for topping later.
Step 4: Assemble Bars
Press the remaining streusel mixture evenly into the bottom of the prepared baking pan. Bake this crust in your preheated oven for 10-12 minutes until slightly set and starting to turn golden. Once done, remove the pan from the oven and immediately pour the raspberry filling over the warm crust.
Step 5: Add Topping & Bake Again
Sprinkle the reserved streusel mixture over the raspberry layer evenly. Return the pan to the oven and bake for an additional 25-30 minutes, or until the topping is golden brown and the raspberry filling is bubbling around the edges. Your Raspberry Streusel Bars are almost ready!
Step 6: Cool & Chill
After baking, remove the pan from the oven and let the bars cool at room temperature for about 30 minutes. Once cooled, place the pan in the refrigerator for at least 2 hours to allow the filling to set properly, making it easier to slice into delightful squares.
