Creamy Peanut Butter Fudge: The Ultimate No-Bake Treat

Few desserts capture the perfect balance between simplicity and indulgence like Creamy Peanut Butter Fudge. Rich, smooth, and packed with nutty flavor, this no-bake classic is a favorite for holidays, gift-giving, or anytime your sweet tooth strikes. Whether you’re a seasoned home baker or a kitchen novice, this guide will walk you through making perfect peanut butter fudge every time.

What Is Peanut Butter Fudge?

Peanut butter fudge is a type of soft candy made by combining peanut butter, sugar, and a fat or dairy element to create a creamy, melt-in-your-mouth confection. It sets without baking and can be customized in endless ways. The result is a dessert that’s sweet, salty, creamy, and utterly addictive.

Unlike traditional chocolate fudge, which requires boiling to a specific temperature, peanut butter fudge is easier to master and doesn’t require a candy thermometer. According to Taste of Home, it’s a great recipe to make with kids or when you want a foolproof dessert in under 30 minutes.

If you’re curious about the science behind fudge, The Spruce Eats explains how controlling sugar crystallization creates that signature creamy texture—something peanut butter does naturally thanks to its smooth fat content.

Why You’ll Love This Recipe

Here are a few reasons why creamy peanut butter fudge is a standout dessert:

No baking required – Just mix, pour, and chill.
Only 5 ingredients – Simple pantry staples.
Fast prep time – Ready to chill in under 10 minutes.
Customizable – Add nuts, chocolate, or swirl-ins.

Essential Ingredients

You don’t need fancy tools or rare ingredients to make perfect fudge. Here’s what you’ll need:

2 cups light brown sugar (packed)
1/2 cup whole milk
3/4 cup creamy peanut butter (not natural)
1 tsp vanilla extract
3 cups powdered sugar (sifted)

Note: Avoid natural peanut butter, which can cause separation. Use a processed, creamy version like Jif or Skippy for best results.

Step-by-Step Instructions

Step 1: Boil Sugar and Milk

In a medium saucepan, combine brown sugar and milk.
Stir constantly over medium heat until it comes to a full rolling boil.
Let it boil for 2–3 minutes, continuing to stir.

This step ensures that the sugar dissolves fully and helps set the fudge properly.

Step 2: Add Peanut Butter and Vanilla

Remove the saucepan from heat.
Stir in the peanut butter and vanilla extract.
Mix until smooth and fully combined.

At this stage, the mixture should be thick, creamy, and fragrant.

Step 3: Mix in Powdered Sugar

In a large mixing bowl, place the sifted powdered sugar.
Pour the hot mixture over the sugar.
Beat with a hand mixer or stir vigorously until no lumps remain and it looks smooth.

Tip: Use a silicone spatula to scrape the sides and ensure even mixing.

Step 4: Set and Chill

Pour the fudge into a greased or parchment-lined 8×8-inch pan.
Smooth the top with a spatula.
Refrigerate for at least 2 hours or until fully set.

Once firm, cut into 1-inch squares and enjoy!

Tips for Success

To make sure your peanut butter fudge comes out perfect every time, follow these key tips:
