Line an 8-inch baking dish with parchment paper. Set aside.
Prepare your mixing bowl by adding the marshmallow cream, white chocolate chips, peanut butter, and maple extract. Set aside.
In a large saucepan over medium high heat, combine sugar, cream, butter, and salt. Bring to a boil. Stirring constantly, boil for a full 4 minutes (ROLLING BOIL). Remove from heat.
Immediately pour hot mixture over marshmallow and peanut butter mixture in mixing bowl. Using your electric mixer, blend until smooth and white chocolate morsels are melted, about 1 minute. Pour into prepared baking dish.
Refrigerate for 3-4 hours until firm. Cut into small pieces and enjoy.
