About the Ingredients

Unsalted Butter

Adding richness, unsalted butter ensures a smooth, creamy base for the fudge.

Light Brown Sugar

This sugar provides a deeper, caramel-like sweetness compared to white sugar, enhancing the fudge's flavor.

Half & Half

Half & half contributes creaminess and helps dissolve the sugar properly, resulting in a smooth texture.

Creamy Peanut Butter

The star ingredient, creamy peanut butter brings its nutty flavor and velvety texture to the fudge.

Vanilla Extract

Vanilla extract enhances the flavor with a warm, aromatic note, rounding out the sweetness.

Powdered Sugar

Powdered sugar thickens the fudge while keeping it soft and smooth.

Tips & Tricks

Use Fresh Ingredients

Ensure that your butter and peanut butter are fresh to achieve the best flavor and texture in your fudge.

Prepare Your Pan

Line your baking pan with parchment paper. This makes removing the fudge easier once it's set.

Be Patient

Allow the fudge to cool completely at room temperature before slicing. This ensures clean cuts and firm squares.

Pro Tips

  • Use an electric mixer to achieve a perfectly smooth consistency.
  • If you prefer a firmer texture, refrigerate the fudge after it has set at room temperature.
  • For a more intense peanut butter flavor, opt for natural peanut butter without added sugars or oils.

Step-by-Step Instructions

Prepare the Pan

Line an 8×8-inch pan with parchment paper and set it aside. This will help you lift the fudge out of the pan once it is set, making it easier to cut into squares.

Combine Butter, Sugar, and Cream

In a medium saucepan over medium heat, melt the butter. Add the brown sugar and half & half, stirring well. Bring the mixture to a boil, ensuring that the sugar dissolves completely.

Boil the Mixture

Allow the mixture to boil without stirring for 1 minute and 45 seconds. This precise boiling time is crucial for achieving the perfect fudge consistency.

Incorporate Peanut Butter and Vanilla

Remove the saucepan from the heat and stir in the peanut butter and vanilla extract until the mixture is smooth and well-combined.

Mix with Powdered Sugar

Pour the hot peanut butter mixture into a large bowl containing the powdered sugar. Beat with an electric mixer until the mixture is completely smooth and free of lumps.

Set the Fudge

Transfer the smooth fudge mixture to the prepared pan, spreading it evenly. Let it cool completely at room temperature until firm.

Slice and Serve

Once the fudge is set, slice it into small squares and enjoy your homemade treat.

Delicious Variations

Chocolate Swirl Peanut Butter Fudge

Swirl in melted semi-sweet chocolate before pouring the fudge into the pan for a delightful chocolate-peanut butter combination.

Crunchy Fudge

Add chopped peanuts to the fudge mixture for extra texture and crunch with every bite.

Salted Peanut Butter Fudge

Sprinkle flaky sea salt on top of the fudge for a delicious sweet-salty balance.

How to Store Creamy Peanut Butter Fudge

Refrigerator

Keep the fudge in the refrigerator for up to 2 weeks for optimal freshness.

Freezer

Wrap individual squares in wax paper and store in an airtight container in the freezer for up to 2 months. Thaw at room temperature before serving.

Room Temperature

Store the fudge in an airtight container at room temperature for up to 5 days.

Reheating

To soften cold fudge, allow it to sit at room temperature for about 15 minutes before serving.

Frequently Asked Questions

Do I need a candy thermometer for this fudge?

No—this recipe is foolproof and doesn’t require one.

Can I use chunky peanut butter instead of creamy?

Yes, but the texture will be less smooth. For best results, stick with creamy peanut butter.

Why is my fudge crumbly?

This usually happens if the mixture is overcooked. Stick to the suggested cooking time.

Can I double the recipe?

Absolutely. Just use a larger pan, like a 9x13-inch dish, to avoid overflow.

What can I use instead of half & half?

You can substitute with equal parts whole milk and heavy cream if half & half is unavailable.
