Notes

Expert Tips: Avoid over-stirring to prevent grainy fudge. Ensure ingredients are at room temperature for smooth combining. Chill thoroughly for at least 4 hours, or overnight, for best texture. Use quality creamy peanut butter for optimal flavor and consistency.
Storage: Store in an airtight container for 2-3 days at room temperature, up to 2 weeks in the refrigerator, or up to 2-3 months in the freezer (wrapped individually).
Troubleshooting: If fudge is too soft, add more powdered sugar and chill longer. If it’s too hard, add a touch of melted butter or milk. Grainy fudge is often caused by over-stirring. Ensure correct ingredient amounts and sufficient chilling time if fudge doesn’t set. Adjust recipe for higher altitudes by increasing cooking time or slightly reducing powdered sugar.

Why This Peanut Butter Fudge Recipe Stands Out

Peanut Butter Fudge recipe
  • Quick and Easy: Ready in minutes with minimal effort, perfect for busy schedules.
  • Simple Ingredients: Uses common pantry staples, so you probably have everything on hand right now.
  • Less Cleanup: No complicated steps or equipment means fewer dishes to wash.
  • Irresistible Flavor: Delivers that classic, rich peanut butter taste that everyone loves.

What You’ll Need To Make Peanut Butter Fudge

Here’s what you’ll need to gather to make this delightful treat:

  • 1 cup butter
  • 1 cup creamy peanut butter
  • 1 teaspoon vanilla
  • 3½ cups powdered sugar

Each ingredient plays a crucial role. The butter adds richness and helps the fudge melt smoothly.

Creamy peanut butter provides that classic, irresistible flavor. Vanilla enhances the overall taste, and powdered sugar is the key to the fudge’s sweet, melt-in-your-mouth texture.

For this recipe, you’ll need just a few basic pieces of equipment. A microwave-safe glass bowl or a medium-size saucepan works great for melting the butter and peanut butter.

A sturdy spatula is essential for stirring and combining the ingredients. An 8-9″ pan is perfect for setting the fudge. Parchment paper is also helpful for easy removal.

How to Make Peanut Butter Fudge: Step-by-Step

I have two methods for this recipe:

  • Microwave Method:
  • Combine the peanut butter, butter, and vanilla in a glass bowl and melt in the microwave for 90 seconds. Stir to combine, it should come together very quickly and be smooth and creamy. Slowly add the powdered sugar a cup or so at a time. Stir to combine thoroughly.
  • Grease an 8-9″ pan with butter or line with parchment. Transfer the fudge mixture to the pan and press into the pan. Chill for at least 4 hours before cutting. Store in an airtight container in the refrigerator.
  • Saucepan Method:
  • Combine the peanut butter, butter, and vanilla in a medium-size saucepan over medium-low heat. Stir to combine, it should come together very quickly and be smooth and creamy. Remove the pan from the heat and slowly add the powdered sugar a cup or so at a time. Stir to combine thoroughly.
  • Grease an 8-9″ pan with butter or line with parchment. Transfer the fudge mixture to the pan and press into the pan. Chill for at least 4 hours before cutting. Store in an airtight container in the refrigerator.

Expert Tips for Perfect Peanut Butter Fudge

  • Don’t Over-Stir: Over-stirring can lead to crystallization, resulting in grainy fudge.
  • Use Room Temperature Ingredients: This helps everything combine smoothly.
  • Chill Thoroughly: Allow the fudge to chill for at least 4 hours, or preferably overnight, for the best texture.
  • Use Quality Peanut Butter: The flavor of your peanut butter directly impacts the flavor of the fudge.

It’s also important to understand how too much stirring can crystallize the sugar. When you over-stir the fudge mixture, you’re agitating the sugar molecules, which can cause them to clump together and form crystals. This results in a grainy texture.

Ingredient Deep Dive: Choosing the Right Peanut Butter

For this recipe, I recommend using creamy peanut butter. It blends beautifully with the butter and powdered sugar, creating a smooth, luscious texture.

You can definitely experiment with natural peanut butter, but be aware that it might result in a slightly different consistency due to the separation of oils. Other nut butters can be used, but the flavor will change the final product.

Sugar Substitutes to Use

While I haven’t tested sugar substitutes extensively with this recipe, you can try using alternatives like erythritol or stevia. Keep in mind that these substitutes might affect the texture and set time of the fudge. You may need to adjust the amount of liquid used.

How to Store Peanut Butter Fudge

  • Room Temperature: Store in an airtight container for up to 2-3 days.
  • Refrigerator: Store in an airtight container for up to 2 weeks.
  • Freezer: Wrap individual pieces in plastic wrap and then place them in a freezer-safe bag or container. Fudge can be frozen for up to 2-3 months.

Troubleshooting Common Fudge Problems

Here are some common issues and how to resolve them:

  • Fudge is too soft: Add a little more powdered sugar, a tablespoon at a time, until it reaches the desired consistency. Ensure it chills for at least 4 hours.
  • Fudge is too hard: This is rare, but if it happens, try adding a touch of melted butter or a bit of milk to soften it.
  • Fudge is grainy: This is usually caused by over-stirring. There’s not much you can do at this point.
  • Fudge doesn’t set properly: Make sure you’re using the right amount of ingredients, and that the chilling process is long enough.

Also, if you live at a higher altitude, you may need to adjust the recipe slightly. Increase the cooking time or reduce the amount of powdered sugar a bit. You can find more information on this by consulting resources on how to make fudge.
