Sprinkle at least 1 cup of the marshmallows evenly over bottom of pan.
Thoroughly combine thawed strawberries and syrup with gelatin; set aside.
In large mixing bowl, combine remaining ingredients. Blend on low speed until

in pan. Spoon strawberry mixture over batter.
Bake for 45 to 50 minutes or until golden brown and a wooden pick inserted in
center comes out clean.
