Streusel Topped Raspberry Squares: Step-by-Step Guide

Step 1: Preheat and Prepare

Begin by preheating your oven to 350°F (175°C). Lightly grease your baking pan or line it with parchment paper to ensure easy removal of the squares once baked.

Step 2: Make the Streusel Base

In a mixing bowl, combine the _ cup flour, _ cup powdered sugar, and a dash of salt. Add the cold, cubed butter pieces. Using a pastry cutter or fork, work the butter into the dry ingredients until the mixture resembles coarse crumbs. Reserve about half of this streusel mixture for the topping.

Step 3: Form the Crust

Press the remaining half of the streusel mixture firmly into the bottom of your prepared pan. This will create a buttery, crumbly base that holds the raspberry filling.

Step 4: Prepare the Raspberry Filling

In a separate bowl, gently toss fresh raspberries with sugar to your desired sweetness. If you like, add a little lemon zest or vanilla extract here for extra flavor. Spread the raspberry mixture evenly over the crust.

Step 5: Add the Streusel Topping

Sprinkle the reserved streusel mixture evenly over the raspberry layer, covering the fruit but leaving some texture visible.

Step 6: Bake to Perfection

Place the pan in the oven and bake for about 35-40 minutes, or until the streusel topping is golden brown and the raspberry filling is bubbling around the edges.

Step 7: Cool and Serve

Remove from the oven and let cool completely in the pan. Once cooled, cut into squares and serve. These bars are delightful on their own or with a scoop of vanilla ice cream.

Flavor-Forward Alternatives

• Swap raspberries for mixed berries: Try a blend of blueberries, blackberries, and raspberries for a dynamic flavor.
• Use stone fruits: Peaches or nectarines make a juicy, sweet filling – similar to the delicious Nectarine Peach Oatmeal Cookie Bars.
• Add nuts to the streusel: Chopped almonds or pecans add extra crunch and a nutty note.
• Incorporate spices: A pinch of cinnamon or cardamom in the streusel can warm up the flavor profile.

Troubles You Can Avoid

• Streusel too soft: Make sure your butter is cold and work quickly when mixing to keep the topping crumbly.
• Fruit filling too runny: Toss your berries with a bit of cornstarch or flour to thicken the filling if you prefer less juice.
• Baking unevenly: Use an oven thermometer to ensure your oven is at the correct temperature and rotate the pan halfway through baking.
• Squares sticking to the pan: Always grease your pan well or line with parchment paper for easy removal.

Top Questions & Answers

Can I use frozen raspberries for these squares?

Absolutely! Just be sure to thaw and drain the raspberries well to avoid excess moisture, which can make the crust soggy. You might also want to add a little extra thickener like cornstarch to the filling.

Is it possible to make these squares vegan?

Yes, you can substitute the butter with a vegan butter or coconut oil. The texture might be slightly different but still delicious. Just ensure your powdered sugar is vegan-friendly.

How do I know when the squares are done baking?

The streusel topping should be a lovely golden brown and the raspberry filling should be bubbling around the edges. If the topping browns too quickly, tent the pan with foil and continue baking until fully cooked.

Can I double this recipe for a larger batch?

Definitely! Simply double all ingredients and use a larger baking pan, adjusting the baking time accordingly. Check for doneness by watching the topping and filling as oven times can vary.
