Finely chop/blend frozen (thawed) strawberries in a food processor or food chopper. You could also do this by hand if needed, although in that case I would suggest chopping them while still partly frozen. If chopping by hand, chop on a paper plate, or something to catch the extra juice, so you can use that too.
Using a stand mixer, or hand mixer, beat cream cheese until fully smooth.
Add strawberry yogurt and blend until smooth. Add chopped strawberries (with juice). Add marshmallow cream. Blend until fully combined.
Put dip in the refrigerator to set up for at least 30 minutes. Serve with fresh fruit of your choice.
Dip will keep well in the refrigerator for 2 days.
