About the Ingredients

Sugar

The backbone of any fudge, sugar provides the sweetness and structure, helping the fudge set perfectly.

Milk

Milk adds creaminess to the fudge, enhancing its rich texture while balancing the sweetness of the sugar.

Peanut Butter

This is the star of the show! Creamy peanut butter gives the fudge its signature flavor and melt-in-your-mouth consistency.

Vanilla Extract

A splash of vanilla extract elevates the flavor profile, adding warmth and depth to the fudge.

Butter (for greasing)

While not an ingredient in the fudge itself, butter is essential for greasing the pan to ensure your fudge releases easily.

Optional Mix-Ins

Consider adding chocolate chips or chopped nuts for an extra layer of flavor and texture!

Tips & Tricks

Use a Candy Thermometer

To achieve the perfect soft-ball stage, a candy thermometer is your best friend. It ensures accuracy and consistency.

Stir Constantly

Stirring continuously while heating prevents the sugar from burning and ensures a smooth fudge.

Cool Completely

Let the fudge cool completely before cutting it into squares for clean, neat edges.

Store in an Airtight Container

To keep your fudge fresh, store it in an airtight container at room temperature away from direct sunlight.

Pro Tips

  • Use Fresh Peanut Butter: For the best flavor, opt for freshly opened peanut butter without added sugars or oils.
  • Experiment with Flavors: Try adding a pinch of sea salt or a drizzle of honey for a unique twist!
  • Cut with a Warm Knife: To make cutting easier, dip your knife in hot water and wipe it dry before slicing.
  • Double the Recipe: If you’re making this for a crowd, consider doubling the recipe for an extra batch of these delightful treats!

Step-by-Step Instructions

Combine Sugar and Milk

In a medium saucepan, combine the sugar and milk over medium heat, stirring until the sugar dissolves.

Bring to a Boil

Continue stirring as the mixture comes to a boil, ensuring it does not stick to the bottom of the pan.

Check Temperature

Using a candy thermometer, monitor the mixture until it reaches 235°F, which is the soft-ball stage.

Add Peanut Butter and Vanilla

Remove the saucepan from heat and stir in the peanut butter and vanilla extract until completely smooth and combined.

Pour and Cool

Butter a baking dish and pour the fudge mixture into it, spreading it evenly. Allow it to cool at room temperature until fully set.

Delicious Variations

Chocolate Peanut Butter Fudge

Swirl in melted chocolate for a rich chocolate-peanut butter flavor that’s simply irresistible.

Nutty Fudge

Add chopped nuts, like almonds or walnuts, for a crunchy texture that complements the creamy fudge.

Coconut Peanut Butter Fudge

Mix in shredded coconut for a tropical twist that brings a chewy texture to this classic treat.

How to Store Peanut Butter Fudge

Refrigerator

Store in an airtight container in the refrigerator for up to two weeks.

Freezer

Wrap individual pieces in plastic wrap and freeze for up to three months for a quick treat anytime.

Reheating

Let thaw at room temperature before enjoying, or microwave for a few seconds to soften slightly.

Frequently Asked Questions

Can I use natural peanut butter?

Yes, natural peanut butter works well, but make sure it’s well-stirred to avoid separation.

Can I add flavors to the fudge?

Absolutely! You can infuse flavors like almond extract or even espresso for a unique twist.

How do I know when the fudge is set?

It should feel firm to the touch and hold its shape when cut into squares.
