Line an 8-inch square pan with parchment paper, leaving overhang on two sides for easy lifting.
02 -
Add the white chocolate chips, sweetened condensed milk, and butter to a large microwave-safe bowl. Microwave in 30-second bursts, stirring well after each, until smooth and glossy.
03 -
Stir in the bubblegum flavoring, vanilla, and pink gel color until evenly blended. Taste a small dab and add no more than 1/4 teaspoon extra flavoring if needed.
04 -
Scrape the mixture into the lined pan and smooth the top with a spatula. Scatter the sprinkles over the surface and press them in lightly.
05 -
Refrigerate for about 2 hours, or until the fudge feels firm in the center and lifts cleanly from the pan.
06 -
Lift the fudge out with the parchment. Cut into 36 small squares using a sharp warm knife wiped dry between cuts.
