Line an 8-inch square baking dish with pan lining paper. This adheres better than regular parchment.

In a large mixing bowl, combine 11 oz bag of white chocolate morsels and marshmallow creme. Set aside.

In a large saucepan over medium high heat, combine sugar, heavy cream, butter and salt. Mix with a wooden spoon until mixture comes to a boil. Continue to stir constantly through a rolling boil, for 4 minutes. Remove from heat and pour over morsels and marshmallow cream, in mixing bowl.

Using an electric mixer with whisk attachment, blend until smooth (about 1 minute). Remove 1/3 of mixture and scoop it into a small bowl.

Add gelatin to large bowl of fudge and whisk until color is fully blended. Pour into prepared baking dish.

To the remaining fudge mixture, fold in miniature marshmallows. Pour white fudge mixture over blue fudge. Place in refrigerator and cool for a about 3-4 hours, until set.

Remove fudge from baking dish by lifting the pan lining paper. Cut fudge into bite sized pieces, separating them slightly.

Melt remaining white chocolate morsels in a microwave safe bowl. Heat in 30 second increments, stirring in between until melted. Pour into a small plastic bag and snip off the corner. Drizzle over bites of fudge.

Immediately press Starmallow onto the top. Add sprinkles if desired.

Store fudge in airtight container in refrigerator for up to two weeks.
