Grease a 9×9 glass pan with Crisco and/or line with parchment paper (I do both- it makes it easier to remove the fudge once it is set). Set pan aside.
Use a Ziploc bag and rolling pin or wooden spoon to crush circus animal crackers into smaller pieces. Set aside
To prepare the strawberry fudge, combine white chocolate chips, butter and sweetened condensed milk in a pot. Heat on medium low heat and stir until completely mixed. White chocolate can burn easily, so watch carefully.
Once fully melted, add marshmallow cream and instant strawberry fudge and whisk until smooth. Pour 2/3 of mix into bottom of glass pan. Set remaining 1/3 aside.
Press 2/3 of the circus animal crackers into the strawberry fudge base.
Prepare the white chocolate fudge by combining the white chocolate chips, butter and sweetened condensed milk in a pot. Heat on medium low heat and stir until completely mixed. White chocolate can burn easily, so watch carefully. Pour mixture over top of strawberry fudge. Poor remaining 1/3 of strawberry fudge on top and swirl with a knife.
Press remaining circus animal crackers into the top of the fudge and add additional sprinkles.
Allow fudge to set in the refrigerator for at least 4 hours. Remove from refrigerator 30 minutes before cutting to allow chocolate to soften slightly. I suggest removing fudge from pan before cutting.
