Storage Tips for Your Peanut Butter Fudge

While the temptation to devour this delightful creation might be strong, knowing how to store it properly ensures lasting freshness. Store in an airtight container at room temperature for up to one week. If you're in a warm climate, you may need to store in the fridge.

Gifting Peanut Butter Fudge

Personalizing peanut butter fudge for gifting is a wonderful idea. Here are some creative ways to add a personal touch:

  • Packaging: Use decorative boxes, jars, or cellophane bags to present the fudge beautifully.
  • Add-ins: Customize the fudge by folding in extras like chopped nuts, dried fruit, or even chocolate chips to create unique flavor combinations.
  • Decorate: Drizzle melted chocolate on top, sprinkle crushed nuts, or dust with cocoa powder for an extra visual appeal.
  • Gift Tags: Attach personalized gift tags with a handwritten note or the recipe, sharing the joy of your homemade creation.

Can I Freeze Peanut Butter Fudge?

Yes, you can freeze peanut butter fudge for longer storage. To do so:

  1. Wrap Well: Ensure the fudge is well-wrapped in plastic wrap or aluminum foil to prevent freezer burn.
  2. Airtight Container: Place the wrapped fudge in an airtight container for added protection.
  3. Label: Clearly label the container with the date to keep track of freshness.
  4. Thawing: When ready to enjoy, allow the fudge to thaw in the refrigerator to maintain its texture.

Note that freezing may slightly alter the texture, so consider freezing smaller portions for easier thawing and consumption.

Can I use salted butter instead of unsalted butter?

While you can use salted butter, it's recommended to stick with unsalted butter in this peanut butter fudge recipe. Using unsalted butter allows you better control over the overall saltiness of the fudge. If you opt for salted butter, expect a saltier tasting fudge.

Peanut Butter Fudge

Only 4 ingredients and 4 minutes to make this wonderful peanut butter fudge. Doesn't get better than that!

Prep Time6 minutes mins

Cook Time4 minutes mins

Total Time10 minutes mins

Course: Candy, Dessert

Cuisine: American

Keyword: easy peanut butter fudge, microwave peanut butter fudge

Servings: 64 1-inch pieces

Calories: 77kcal

Author: Nikki Gladd

Ingredients

  • 1 cup unsalted butter , plus additional for greasing pan
  • 1 cup creamy peanut butter
  • 1 teaspoon pure vanilla extract
  • 1 lb powdered sugar (or about 3 ¾ cups), unsifted

Instructions

  • Butter the bottom and sides of an 8- x 8-inch pan, and then line the bottom and sides of the pan with a sheet of parchment paper. (The butter helps the paper stick to the pan.) Lightly butter the top of the parchment paper, as well.

  • Combine the 1 cup butter and peanut butter in a large microwave safe bowl, cover with plastic wrap and microwave on full power for 2 minutes. Carefully remove the bowl from the microwave, uncover and stir with a rubber spatula or wooden spoon. Recover and microwave on full power for an additional 2 minutes.

  • Remove the bowl from the microwave. Carefully stir in the vanilla and powdered sugar until evenly combined. The mixture may become a little crumbly at first, but continue to stir until the ingredients are smooth and a nice "dough" forms.

  • Pour the mixture into the prepared pan and spread into an even layer, pushing to fill the corners. Place an additional square piece of parchment paper directly on the surface of the fudge and use your hands to smooth the top.

  • Refrigerate at least 2 hours. Once chilled, transfer fudge to a cutting board by lifting the sides of the parchment paper. Use a large knife to cut into 1-inch cubes.

  • Store in an airtight container at room temperature for up to 1 week.

Notes

Be careful when measuring the powdered sugar. 1 lb (or 16 oz) of powdered sugar is equal to 3 ¾ to 4 cups. Do not think in terms of liquid measurement where 16 ounces equals only 2 cups.
