How To Store / Freeze This Recipe
Allow the peanut butter crispies to cool completely before storing. This ensures they maintain their shape and texture.
For short-term storage, place the squares in an airtight container. Layer them with parchment paper to prevent sticking.
Store the container at room temperature for up to one week. This keeps the crispy rice cereal from becoming soggy.
For longer storage, wrap each square individually in plastic wrap. This extra step helps preserve freshness and prevents freezer burn.
Place the wrapped squares in a freezer-safe bag or container. Label with the date to keep track of freshness.
Freeze the peanut butter crispies for up to three months. When ready to enjoy, thaw at room temperature for about 15-20 minutes.
Avoid refrigerating the squares as it can make them too hard and affect the texture.
If you prefer a softer texture, microwave a square for 5-10 seconds after thawing. This will slightly warm the peanut butter mixture and make it more pliable.
Always ensure the storage area is cool and dry to maintain the best quality of your dessert.
How To Reheat Leftovers
For a quick and easy method, use the microwave. Place your peanut butter crispies on a microwave-safe plate and heat them on medium power for about 10-15 seconds. This will soften them up without making them too hot.
If you prefer a more even reheating, try the oven. Preheat your oven to 300°F (150°C). Place the peanut butter crispies on a baking sheet lined with parchment paper. Heat them for about 5-7 minutes, keeping an eye on them to ensure they don't overcook.
For a slightly crispier texture, use a toaster oven. Set the toaster oven to a low setting and place the peanut butter crispies on the rack or a small baking tray. Heat for 3-5 minutes, checking frequently to avoid burning.
If you're in a rush, you can use a stovetop. Place a non-stick skillet over low heat and add the peanut butter crispies. Stir them gently for about 2-3 minutes until they are warmed through.
For a fun twist, try reheating them in a waffle iron. Preheat the waffle iron and place a piece of parchment paper inside. Add the peanut butter crispies and close the lid for about 1-2 minutes. This will give them a unique texture and warm them up nicely.
