Coconut Brown Sugar Fudge

Line an 8-inch square baking pan with parchment paper, leaving a 2-inch overhang on all sides. Lightly coat pan with cooking spray. Stir together sugar, condensed milk, and whole milk in a medium saucepan. Cook over medium-low, stirring constantly, until a candy thermometer registers 238°F, about 16 minutes. Transfer sugar mixture to the bowl of a stand mixer fitted with a paddle attachment.

Add white chocolate, butter, and coconut extract to stand mixer bowl; beat on low speed until white chocolate and butter are melted, about 1 minute. Increase mixer speed to medium, and beat until thickened and no longer shiny, 5 to 6 minutes. Halfway through beating the white chocolate mixture on medium, add 1 cup of shredded coconut. Pour into prepared pan; gently tap bottom of pan on counter until top is an even layer. Sprinkle with remaining shredded coconut, gently pressing to adhere. Let cool, uncovered, at room temperature until firm, at least 2 hours or up to 12 hours. Remove from pan using parchment paper overhang as handles. Cut into 64 (1-inch) squares.
