The History of Peanut Butter Fudge

Ingredients for the Best Peanut Butter Fudge

Here’s what you’ll need to make this amazing Peanut Butter Fudge recipe:

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

Ingredient Deep Dive

Let’s take a closer look at what each ingredient brings to the table. I recommend using creamy peanut butter for the smoothest texture; I tend to use a mainstream brand, but if you opt for natural peanut butter, be sure to stir it very well before measuring.

Some people like to avoid peanut butter that has hydrogenated oil in the ingredients, if that’s you, be sure to check the label! The vegetable shortening helps create a tender, melt-in-your-mouth texture. I always use pure vanilla extract, and don’t skimp. It really rounds out the flavor profile of this recipe.

Troubleshooting: Common Peanut Butter Fudge Problems

Sometimes, things don’t go exactly as planned. Here’s how to troubleshoot common Peanut Butter Fudge issues:

  • Why is my fudge too soft? This could be due to using too much shortening or not chilling it long enough. Make sure to measure accurately and allow ample chilling time.
  • Why is my fudge too hard? Overmixing, or using too little shortening can lead to a too-hard fudge.
  • Why is my fudge grainy? Graininess can result from overmixing after adding the powdered sugar or using peanut butter that is not smooth.
  • Why is my fudge oily? This can happen if the peanut butter separates or if there’s too much shortening.

Variations and Substitutions

Want to mix things up? Here are a few ideas:

VariationIngredientsInstructions
Swirled FudgeAdd a layer of melted chocolate or a different nut butter, like almond or cashew butterSwirl the chocolate or nut butter into the peanut butter fudge before chilling.
Layered FudgeAdd a layer of peanut butter cups, or cookie crumbs.Layer your favorite cookies on the bottom of the pan before pouring the fudge mixture on top, and sprinkle some extra crumbs on top.
Flavored FudgeMaple extract, instant coffeeAdd the extract to the peanut butter mixture before adding the powdered sugar.

Storing and Serving Your Peanut Butter Fudge

To keep your Peanut Butter Fudge fresh, store it in an airtight container in the refrigerator. It will last for up to two weeks. You can also freeze it for longer storage; just wrap it tightly in plastic wrap and place it in a freezer-safe bag. I like to cut it into fun shapes, or serve it with a scoop of vanilla ice cream!

Peanut Butter Fudge Makes A Great Gift

Peanut Butter Fudge is a thoughtful homemade gift, especially around the holidays. I like to package fudge in small cellophane bags tied with a ribbon, or in decorative tins lined with parchment paper. A personalized tag adds a special touch.

Adjustments for High Altitude Baking

If you live at a high altitude, you may need to make a few adjustments to this recipe. Since liquids evaporate more quickly at higher altitudes, you might need to add a tablespoon or two of milk to the mixture to prevent it from becoming too dry.

Candy Thermometer vs. No Thermometer

This recipe does not require a candy thermometer, making it incredibly easy. However, some fudge recipes do benefit from using one. The goal is to reach the “soft-ball” stage, around 235-240°F (112-115°C), which ensures the fudge sets properly.
