Delicious homemade buttery streusel bars with a tart black raspberry filling, perfect for a quick and easy dessert that pleases any crowd.
Keep butter cold to ensure a crumbly streusel. Pre-bake the crust to prevent sogginess. Let bars cool completely or refrigerate before cutting for clean slices. Cover with foil if streusel browns too fast. Use parchment paper for easy removal.
