Ingredient Notes

raw ingredients to make homemade peanut butter fudge on table
  • White Chocolate: We like to use high-quality white chocolate chips for the best flavor. You can also use vanilla melting wafers or vanilla almond bark.
  • Sweetened Condensed Milk: This is the secret ingredient that adds sweetness and gives your fudge its smooth, creamy texture. Don’t skip it! Evaporated milk is not the same.
  • Peanut Butter: Creamy peanut butter gives the perfect smooth texture, but if you prefer a little crunch, you can also use chunky peanut butter. DO NOT use a natural peanut butter in this recipe as results will vary. We recommend Jiff or Skippy.
  • Vanilla Extract: Use pure vanilla extract for the best flavor.

Adding Nuts

You can use a chunky style of peanut butter in this recipe rather than the smooth style. Or you can also add 1/2 cup of roughly chopped peanuts into the fudge mixture just before pouring it into your pan to refrigerate.

Variations

This classic fudge recipe is a perfect base for adding your favorite flavors and mix-ins. Here are some ideas to get creative:

Flavor Extracts: Swap out or complement the vanilla extract with almond or chocolate extract. Use 1/2 teaspoon.

Nuts: Stir in 1/2 to 1 cup of chopped walnuts, pecans, pistachios, or almonds for crunch.

Marshmallows: Fold in mini marshmallows after stirring the fudge for a gooey twist.

Sprinkles: Top the fudge with colorful sprinkles for festive fun.

Microwaving Fudge

All ingredients can be combined directly in a microwave-safe bowl. Microwave on high in 30-second increments, stirring in between. Avoid microwaving for too long or in longer periods, as this can cause the chocolate to burn and become grainy. The ingredients will continue to melt as you stir, so it’s best to stop and stir until only small lumps remain.

Storage Instructions

Refrigerate leftovers in an airtight container preferably in a plastic storage container or a resealable plastic bag, but you can also wrap it in aluminum foil. It will stay good in the fridge for about 3 weeks.
