1cupcake mix (any flavor, such as vanilla or funfetti)
0.5cupchopped nuts (optional, such as walnuts or pecans)
Instructions
Begin by preparing your baking dish. Line an 8x8-inch square baking dish with parchment paper, ensuring there is some overhang on the sides to facilitate easy removal later. Set the lined dish aside.
In a medium saucepan, over low heat, add the white chocolate chips and the sweetened condensed milk. Stir the mixture continuously with a spatula or wooden spoon until the white chocolate is fully melted and the mixture is smooth and glossy.
Once melted, remove the saucepan from the heat. Carefully mix in the vanilla extract and sea salt until fully combined.
Slowly sift the cake mix into the chocolate mixture, stirring gently but thoroughly until the cake mix is well incorporated, and there are no lumps.
Gently fold in the rainbow sprinkles and chopped nuts (if you choose to add them), ensuring an even distribution throughout the fudge mixture.
Transfer the colorful fudge mixture into the prepared baking dish. Use a spatula to spread it out evenly across the dish, smoothing the top for a neat finish.
To add a festive touch, sprinkle extra rainbow sprinkles on top of the fudge, lightly pressing them into the surface for better adhesion.
Place the baking dish in the refrigerator for at least 2 hours, or until the fudge has completely set and firmed up.
Once the fudge has set, use the parchment overhang to lift it out of the baking dish. Place it on a cutting board and cut into squares for serving.
Notes
For a whimsical display, arrange the fudge squares on a vibrant cake stand or decorative platter. Individually wrap pieces in colorful cellophane tied with ribbons for party favors.
