Aunt Sue shared this secret hack and it honestly tastes like it came from a fancy bakery. You will not believe how easy it is to make.

Cool and set: Let the pan sit at room temperature for about 30 minutes, then transfer it to the refrigerator for at least 1–2 hours, or until the fudge is firm to the touch. Chilling helps you get clean slices, though the texture will soften slightly again once it returns to room temperature.
Slice and serve: Once fully set, use the parchment overhang to lift the fudge out of the pan onto a cutting board. With a sharp knife, trim the edges if you like, then cut into 1- to 1½-inch squares. Wipe the knife with a warm, damp cloth between cuts for neater edges. Arrange the squares back in the pan or on a platter, and store any leftovers in an airtight container at cool room temperature for up to 3 days or in the refrigerator for up to a week.
Variations & Tips
To adjust the sweetness, use a pinch more sea salt or swap in a cream cheese–flavored frosting for a slightly tangier profile. For a more pronounced bakery-style vanilla, add an extra 1/2 teaspoon of vanilla extract or a drop or two of almond extract (almond can be strong, so go slowly). You can shift the theme by changing the sprinkles: use pastel confetti for spring, red and green jimmies for winter holidays, or team colors for game day. Stir in 1/2 cup of add-ins like mini marshmallows, chopped toasted almonds, or crushed sandwich cookies for extra texture—just fold them in gently with the sprinkles. If you prefer stovetop melting, warm the frosting in a small saucepan over low heat and melt the white chocolate in a heatproof bowl set over a pot of barely simmering water, then combine as directed. For a thinner fudge (good for bite-size pieces), use a 9×9-inch pan; for thicker, bakery-style squares, stick with the 8x
8. You can also line a metal loaf pan and make a half batch if you just want a small treat for the week.
