• Freezer Magic: Wrap individual bars in plastic wrap, then place them in a freezer-safe container. These treats can stay frozen for up to 3 months, making them a perfect make-ahead dessert for unexpected guests or sweet cravings.
• Room Temperature Tips: If you prefer softer bars, let them sit at room temperature for 15-20 minutes before serving. This allows the butter in the crumble to soften slightly, enhancing the overall taste and texture.
