Make Ahead Tips

This fudge is perfect to make a day or two ahead. Just keep it covered in the fridge until ready to serve.

Instructions

Step 1: Melt the Chocolate Mixture

Add 2 cups milk chocolate chips, 1 can (14 oz) sweetened condensed milk, and 1 cup creamy peanut butter to a saucepan. Heat on low, stirring constantly until everything is fully melted and smooth.

Step 2: Stir in Butterfinger Pieces

Remove from heat. Fold in 1 ½ cups crushed Butterfinger candy bars, mixing until evenly spread throughout the thick fudge mixture.

Step 3: Pour and Spread

Pour the mixture into a parchment-lined 8×8 pan. Spread it out evenly using a spatula.

Step 4: Chill and Set

Place the pan in the fridge for about 2 hours or until fully firm. Once set, lift out and cut into 16 squares.

Why This Recipe Works (Quick Science)

Sweetened condensed milk acts as both a sweetener and binder, giving the fudge its smooth, creamy texture. The chocolate provides structure as it cools, while peanut butter adds richness and keeps it from getting too hard. The Butterfinger pieces bring that crisp texture that makes each bite interesting.

Common Mistakes

Heating too fast: Chocolate can burn quickly, so always use low heat
Not stirring enough: This can cause uneven melting
Skipping parchment paper: Makes removing the fudge much harder
Cutting too early: Warm fudge will fall apart

What to Serve With

A cup of hot coffee
Vanilla ice cream
Fresh berries for contrast
A glass of cold milk

FAQ

Can I use a microwave instead of the stove?
Yes! Heat in 30-second intervals, stirring each time until smooth.

Can I double the recipe?
Absolutely. Just use a 9×13 pan.

Why is my fudge too soft?
It may not have chilled long enough, or the ratio of ingredients was slightly off.

Can I use natural peanut butter?
It’s not ideal—it can separate and affect the texture.
