How to Make Homemade Mars Bar Candy Bars

Step 1: Prepare the Pan

Line an 8×8-inch baking dish with parchment paper, leaving overhang for easy removal.

Step 2: Make the Nougat Layer

In a saucepan over medium heat, melt butter.

Add sugar and evaporated milk, stirring until dissolved and slightly thickened (about 4–5 minutes).

Remove from heat and stir in:

  • Marshmallow fluff

  • Peanut butter

  • Vanilla extract

Mix until smooth.

Spread evenly into prepared pan.

Refrigerate for 30–45 minutes until firm.

Step 3: Add the Caramel Layer

In a microwave-safe bowl, melt caramels with heavy cream in 30-second intervals, stirring until smooth.

Pour over chilled nougat layer.

Spread evenly and refrigerate again for about 30 minutes.

Step 4: Cut Into Bars

Lift the chilled mixture from the pan and cut into bars or squares.

Place on a lined tray.

Freeze for 20–30 minutes before dipping.

Step 5: Coat in Chocolate

Melt chocolate chips (and coconut oil if using) until smooth.

Dip each bar into melted chocolate, fully coating.

Place on parchment paper to set.

Refrigerate until chocolate hardens.

Expert Tips
