Stephen's Chocolate Peanut Butter Marble Fudge

After hunting for the 'perfect' recipe, I decided to experiment on my own. This received rave reviews. We now just refer to it as "Stephen's Fudge". This has been adapted from an Eagle Brand recipe. Cooking time is chilling time. UPDATE Aug 18/08: I'm very happy to say that this recipe won Second Place in the Eagle Brand Category at our local fair.

• Ready In: 3 hrs 30 mins
• Serves: 30
• Yields: 30 squares

Ingredients

• 2  cups  milk chocolate chips
• 1  cup  peanut butter chips
• 1 (300 ml) can sweetened condensed milk (not evaporated)
• 2  teaspoons vanilla extract
• 4 -5  tablespoons peanut butter (I use extra creamy)

Directions

1. Lightly spray an 8 x 8 pan with oil. Lining it with parchment paper also works well.
2. In a medium saucepan, mix together chocolate chips, peanut butter chips and sweetened condensed milk. Heat at medium temperature until chips have melted and mixture is smooth.
3. Remove from heat and add the vanilla.
4. Spread in the prepared pan.
5. While still warm, add dollops of the peanut butter, and swirl with a knife to create the marble effect.
6. Chill for at least 3 hours or until firm before cutting.
