Ingredients

You'll have this fudge ready to enjoy in no time with only 2 ingredients. Below are helpful ingredient notes. Remember to see the recipe card at the bottom for all ingredient information.

• Creamy peanut butter - Stay away from all-natural peanut butter for this recipe; it is too thin to set up properly as fudge. Choose a creamy peanut butter with salt in the ingredients list so the fudge isn't too sweet. You need a 16-ounce jar.
• Vanilla frosting - Choose a high-quality frosting, not the budget store brands for the best flavor. Stay away from whipped frostings and choose creamy instead. Duncan Hines Creamy Vanilla frosting is vegan and gluten-free friendly.
• Sea salt (optional) - If you like a sweet-and-salty fudge, add some flaky sea salt on top before chilling. This is optional and depends on your preference. I make it without the added salt and enjoy the flavor, but it may be too sweet for some.

Step-by-Step Instructions

Instead of cooking the fudge on the stove, use a microwave to soften the peanut butter and frosting. Here are step-by-step instructions for how to make no-bake peanut butter fudge with 2 ingredients.

STEP 1: Add the creamy peanut butter to a microwave-safe bowl and heat it in the microwave in 15-second increments until smooth and easy to stir. This usually takes 30-60 seconds total.

STEP 2: Use a rubber spatula to mix in the vanilla frosting. Heat it in the microwave for an additional 15-30 seconds as necessary to combine.

STEP 3: Mix the fudge until thick and evenly combined. It should hold its shape but will be soft and malleable in the bowl.

STEP 4: Transfer the thickened peanut butter fudge to an 8x8-inch baking pan lined with parchment paper. Use a spatula or your hands to smooth the fudge into the corners evenly.

STEP 5: If desired, add flaky sea salt to the top of the fudge. Place the fudge in the fridge for at least 2 hours to set up and become solid. To remove the fudge, run a knife around the edges of the fudge and lift the parchment paper out.

STEP 6: Slice the fudge into bite-sized squares and enjoy immediately. It is easier to slice after it sits for 10 minutes at room temperature. Store leftover no-bake peanut butter fudge in an airtight container in the fridge so it stays fresh.

TIP: For thinner fudge, you can use an 8x13-inch baking pan instead.

Expert Fudge Making Tips

• Sprinkle flaky sea salt on top of the fudge for a delicious sweet-and-salty flavor.
• Watch the microwave time while you heat the peanut butter. It can go from softened to burnt very easily, so don't melt it longer than 15-30 second intervals!
• Use salted creamy peanut butter for the best taste. Crunchy peanut butter will be too hard to mix and all-natural peanut butter does not have as much flavor.
• If your frosting is a thin and runny consistency, don't melt it with the peanut butter. Fold it into the softened peanut butter with a spatula so the fudge isn't too soft.
• Don't use whipped frosting. It is too soft and doesn't set up properly with the peanut butter. Creamy canned frosting is best, like Betty Crocker, Duncan Hines, or Pillsbury.

Easy Fudge Recipe Variations

If you want to get creative, add some extra flavor, or serve the fudge at a festive holiday party, here are some easy ways to customize the fudge to your liking!

• With chocolate chips - Fold in mini chocolate chips to make chocolate peanut butter fudge. Make it with white chocolate for a sweeter taste!
• Round fudge balls - Make no-bake-peanut butter fudge balls instead of traditional fudge squares by using a cookie scoop to form balls of fudge. Chill them on a baking sheet instead of in a square pan.
• With sweetened condensed milk - Instead of frosting, use 1 cup of sweetened condensed milk and heat it in the microwave with the peanut butter until smooth.
• With cream cheese - Use a jar of cream cheese frosting for a sweet and decadent peanut butter fudge. This adds a slightly tangy flavor!
• Add sprinkles - For festive holiday fudge, press your favorite sprinkles into the top of the fudge before chilling.
