Frequently Asked Questions

Can I use regular marshmallows instead of mini marshmallows?

Yes, you can use regular marshmallows, but you'll want to cut them into smaller pieces to ensure they melt and distribute evenly throughout the batter. Mini marshmallows tend to melt more quickly and integrate better into the squares.

What can I do if my squares are too dry?

If your squares turn out dry, it may be due to overbaking. Make sure to check them a few minutes before the suggested baking time. You can also add a bit more shortening or butter next time to keep them moist. Serving them with ice cream can help balance the texture as well.

Can I freeze these squares?

Absolutely! Marshmallow Mud Squares freeze well. Wrap them tightly in plastic wrap and place them in an airtight container. They can be stored in the freezer for up to 3 months. When ready to enjoy, thaw them in the refrigerator overnight before serving.
