FAQ
Can I use regular marshmallows instead of mini?
Yes, but chop large marshmallows into smaller pieces first so they distribute evenly throughout the bars and don't create large gaps.
How long do these bars keep?
Store covered at room temperature for up to 1 week. They actually taste better after the first day as flavors meld together.
Can I freeze these bars?
Yes, wrap individually and freeze for up to 3 months. Thaw at room temperature for 30 minutes before serving for best texture.
