Line an 8-inch x 8-inch square baking pan with parchment paper, set aside.
In a small saucepan over low heat, add sweetened condensed milk and white chocolate chips. Stir until they start melting together.
Once melted, add in Hedessent Irish Cream and mix together well. Pour into lined baking tray.
Dot the top of the white chocolate mixture with melted chocolate chips. Use a butter knife to swirl the chocolate creating a marbled effect.
Let this sit in your fridge for 5-6 hours. Once the fudge is solid, it's ready to cut into smaller bars, and enjoy!
