  • Add a pinch of espresso powder to the batter to deepen the chocolate flavor.

Storage

FAQs

Can I use regular marshmallows instead of mini marshmallows?

Yes, you can chop regular marshmallows into smaller pieces and sprinkle them on top, but mini marshmallows melt more evenly and create that signature gooey layer.

What can I use instead of evaporated milk in the frosting?

You can substitute evaporated milk with regular milk or half-and-half, but the frosting might be slightly less rich. Adjust powdered sugar as needed to achieve your preferred consistency.
