Ingredients
Servings: 24
-
3 cups (about 18 oz / 510 g) semi-sweet chocolate chips or chopped dark chocolate

-
1/4 cup (60 ml) Irish whiskey

Ingredient Notes
Chocolate: Use semi-sweet chocolate chips or chopped dark chocolate.
Sweetened condensed milk: Use full-fat sweetened condensed milk.
Irish whiskey: Adds warmth and depth.
Unsalted butter: Adds richness.
Step-by-Step Instructions
Step 1: Prepare the Pans
Line two small foil trays or loaf pans with aluminum foil, letting it overhang the sides. Lightly grease the foil with butter.
Step 2: Melt the Chocolate
Set a small or medium slow cooker to LOW. Add the chocolate, sweetened condensed milk, and butter to the crock. Cover and let warm for about 45 minutes, without stirring for the first 20 minutes.
Step 3: Stir the Mixture
Remove the lid and stir the mixture slowly with a heatproof spatula until completely smooth and glossy. If there are still solid bits of chocolate, cover and cook in 10-minute increments.
Step 4: Cool Slightly
Turn off the slow cooker or switch to WARM. Let the mixture sit uncovered for 5 to 10 minutes, stirring occasionally.
Step 5: Add the Whiskey
Stir in the Irish whiskey, mixing until fully incorporated and the fudge is thick, shiny, and smooth.
Step 6: Pour and Set
Immediately pour the fudge mixture into the prepared foil-lined trays. Spread it evenly and smooth the top. Let the trays sit at room temperature until cooled and firm, about 2 to 3 hours. For a cleaner cut, refrigerate for at least 1 more hour.
Step 7: Cut and Serve
Lift the fudge out of the trays using the foil overhang. Place on a cutting board, peel back the foil, and cut into even squares.
