Yes, you can replace peanut butter with more butter, but using the same amount might not yield the best texture or flavor. Typically, peanut butter adds moisture and a distinct flavor, so consider using 1 cup of a different nut butter or a seed butter (like sunflower seed butter) instead of butter. If using butter, try starting with ¾ cup and adjust the dough’s consistency as needed.

So glad you and your kids loved them! You can freeze them. Wrap them in two layers of plastic wrap, place them in a freezer-safe container or zipper-top bag, and freeze for 4-5 months. Then, thaw at room temperature for a few hours when you want to eat them again.
