Step 1: Prepare the Nougat

1. Line an 8×8-inch baking pan with plastic wrap or parchment paper.
2. In a microwave-safe bowl, melt 3 ½ cups of milk chocolate chips in 30-second intervals, stirring between each round, until smooth.
3. Let the melted chocolate cool slightly, then add the whipped topping.
4. Using a hand mixer or whisk, blend until the mixture is smooth and fluffy.

Step 2: Shape & Freeze the Nougat

5. Spread the mixture evenly into the prepared baking pan.
6. Smooth the top with a spatula and place in the freezer for 30-40 minutes until firm.

Step 3: Cut the Bars

7. Once set, lift the nougat from the pan using the plastic wrap.
8. Place it on a cutting board, remove the wrap, and cut into 32 bars.
9. Arrange bars on a parchment-lined tray and freeze again for 30 minutes.

Step 4: Melt the Coating Chocolate

10. In a clean microwave-safe bowl, melt the remaining milk chocolate chips with vegetable shortening, stirring in 30-second intervals until smooth.

Step 5: Coat the Bars

11. Using a fork or dipping tool, dip each bar into the melted chocolate, ensuring even coverage.
12. Let excess chocolate drip off before placing on the parchment-lined tray.

Step 6: Let the Chocolate Set

13. Transfer the tray to the refrigerator and chill until the chocolate hardens.
14. Once set, enjoy your homemade 3 Musketeers Bars!
