Step 1: Prepare the Pan
Line an 8 x 8 inch pan with parchment paper ensuring a slight overhang for easy removal later. This prevents sticking and ensures tidy edges.
Step 2: Melt the Ingredients
In a saucepan over low-medium heat, melt the butter. Stir in the chocolate chips and sweetened condensed milk. Stir continuously to evenly melt and prevent burning. Avoid boiling, as this affects texture.
Step 3: Pour and Smooth
Once melted, promptly pour the fudge mixture into the prepared pan. Use a spatula to smooth the top, ensuring even thickness for perfect squares.
Step 4: Chill the Fudge
Cover and refrigerate the fudge for at least 2 hours to set completely. Overnight chilling further enhances the luscious texture and makes cutting easier.
Step 5: Cut into Squares
Once set, lift the fudge using the parchment overhangs and place it on a cutting board. Cut into 36 squares, letting the rich, chocolatey aroma entice you.
