Line an 8x8 pan with parchment paper, making sure that the parchment paper extends past the pan so that you can lift the fudge out of the pan after it sets.
In a large microwave-safe bowl, combine 1 ½ cups of white chocolate chips, ½ of the sweetened condensed milk, and half of the salt. Microwave for 30 second increments, making sure to stir in between, until mostly melted.
3 cups white chocolate chips, 14 ounces sweetened condensed milk, 1/8 teaspoon salt
Then, stir until fully melted and smooth.
Stir in the vanilla extract. Add 2-4 drops of food coloring (until you reach your desired coloring), and mix until thoroughly incorporated.
1 teaspoon vanilla extract, 2-4 drops red food coloring
Spread mixture into the bottom of the pan in an even layer, and allow it to sit for about 30 minutes to set.
Once set, repeat the process again, but do not add food coloring to this layer. Spread the fudge over the first layer.
Place the Valentine’s day sprinkles on top of the fudge, use your hands to slightly press the sprinkles in to make sure they stay in place after they set.
