Start by preparing your 8x8 square baking pan by lining it with parchment paper or aluminum foil.

Next, fill a small saucepan with about an inch of water and bring to a simmer. Grab a large heat-proof bowl and place bowl over the simmering pan of water. Pour the white chocolate baking chips into the bowl along with the butter, sweetened condensed milk, and Fireball whisky. Whisk until butter and chocolate are melted.

Remove the mixture from the heat and place 1/4 cup of the mixture into a small bowl. Add your food dye and stir to combine. Set aside.

Pour the white fudge mixture into the prepared pan and use a knife to even out the mixture. Drizzle on the food coloring mixture and use a toothpick to swirl the color into the fudge.

Place the fudge in the fridge for at least 2 hours to set. When ready, remove the fudge from the pan and slice into bite-size squares. Serve.
