If you have any leftover chocolate buns (though it's hard to resist them!), store them in an airtight container to maintain their softness. At room temperature, these buns will typically stay fresh for about 2 to 3 days. If you'd like them to last longer, consider refrigerating them, but be aware this may slightly change their texture, making them firmer. For optimal freshness, you can also freeze the buns. To do this, wrap each bun tightly in plastic wrap, followed by a layer of aluminum foil, ensuring no air can compromise their texture. Frozen buns can last for up to 3 months. When ready to enjoy, simply thaw them at room temperature or warm them briefly in the oven to restore their delightful softness.
