You might want to save this fudge for the adults-only dessert table. Milk chocolate and Irish cream liqueur combine to make one delicious, spiked fudge perfect for an after dinner treat alongside coffee.
Prepare an 8-inch square pan by lining it with parchment, set aside.
Combine the sugar, butter, and cream in a large saucepan over medium-high heat. Stir while the mixture comes to a boil. Continue to boil for 3 to 4 minutes.
Then, remove the pan from the heat, and add the Irish cream liqueur.
Combine the chocolate and marshmallow cream in a large mixing bowl. Pour the hot Irish cream mixture over top. Mix to melt the chocolate. Using an electric mixer, beat the mixture until creamy, about 1 to 2 minutes.
Pour the fudge into the prepared pan, and refrigerate until firm, about 4 hours.
