Super easy Peanut Butter Fudge! All you need is 2 ingredeints vanilla frosting, and creamy PB! Pop it in the microwave, mix and chill for foolproof PB fudge!

This 2 ingredient peanut butter fudge is stupid easy (it takes 3 minutes to combine in the microwave!), tastes amazing, and is perfect on those days when the clock is ticking and you need a quick-fix PB fudge recipe. (Que the last-minute bake sale or class party reminder from your child 🫠) It’s smooth, it’s peanut buttery, and it has the exact same melt-in-your-mouth fudgey goodness that you get from peanut butter fudge recipes with a mile-long ingredient list. The simplicity of using the microwave to combine vanilla frosting and peanut butter to make this fudge makes it almost feel like you’re bending the candy-making rules in the best way possible. Seriously, after you make this recipe, you’re going to be kicking yourself for not trying it sooner!

Now, I know what you’re thinking: “Can it really be that simple to make peanut butter fudge?” Not gonna lie; I had my doubts, too. I mean, taking a shortcut with the microwave and just vanilla frosting and peanut butter sounded too good to be true, and we all know what they say about things that are too good to be true. But life’s too busy for long recipes when you’ve got a big family, so I tried it! So, there I was, a bit skeptical but mostly curious. The PB Fudge was either going to be a total flop or a “how did I live without this recipe.” Spoiler alert: it was the latter.

Ingredients to Make 2 Ingredient Peanut Butter Fudge

  • Vanilla Frosting: Choose a “regular” vanilla frosting for the best texture (you don’t want to use a cream cheese one here). A standard store-bought container will do the trick, but feel free to opt for organic or natural versions if you prefer. The key is to find a frosting that complements the peanut butter without overpowering it and it just tasting like sugar.
  • Creamy Peanut Butter: Look for a peanut butter that’s made with just peanuts and no added sugar. This helps to keep the fudge from becoming overly sweet and maintains a nice balance with the vanilla frosting. The creaminess of the peanut butter is essential for that perfect fudge texture.

How to make Peanut Butter Fudge In the microwave

Prepping the Pan:

  • Line the Pan: Start by lining an 8×8 inch pan (or a similar-sized pan) with foil or parchment paper. This makes removing the fudge easier later.
  • Spray the Lining: Lightly spray the lining with non-stick spray to prevent sticking.

STEP 1: COMBINING THE INGREDIENTS

  • Mix the Fudge Base: In a microwave-safe bowl, combine the vanilla frosting and creamy peanut butter. Stir them together until they’re well mixed.

STEP 2: MICROWAVING THE MIXTURE

  • First Microwave Cycle: Heat the mixture in the microwave for one minute. Then, carefully remove it and give it a good stir.
  • Additional Heating (If Needed): If the mixture isn’t smooth and cohesive after the first minute, heat it for an additional 30 seconds and stir again.

STEP 3: SETTING THE FUDGE

  • Transfer to the Pan: Pour the smooth fudge mixture into your prepared pan. Use a spatula to spread it evenly across the pan.
  • Let It Set: Allow the fudge to set at room temperature for about 4 hours, or chill it in the fridge for about 2 hours or until it’s firm.

STEP 4: SLICING AND SERVING

  • Slice the Fudge: Once set, lift the fudge out of the pan using the edges of the foil or parchment paper. Slice it into squares or desired shapes.
  • Serve and Enjoy: Your 2 Ingredient Peanut Butter Fudge is ready to be enjoyed! Perfect as a sweet treat for any occasion.

Ingredients
  

  • 16 oz container vanilla frosting
  • 2 cups creamy peanut butter

Instructions

  • Line an 8×8 baking dish or similar sized pan parchment paper. Spray a thin layer of non-stick spray on the bottom and sides.
  • In a glass microwave safe bowl, combine the vanilla frosting and creamy peanut. Stir to combine.
  • Heat for 30 seconds, remove from the microwave and stir well. Pop it back in for another 30 seconds and stir again make sure it's well combined. If needed, heat for an additional 30 seconds and stir again. The fudge should be smooth and lump free.
  • Pour the fudge into the lined baking dish. Use a spatula and spread the PB fudge in an even layer.
  • Chill in the fridge for 2 hours or until set.
  • Slice with a warm knife and serve.

Notes

    • Quality Ingredients Matter: Since this recipe only has two ingredients, each one counts. Choose a high-quality vanilla frosting and a creamy peanut butter that you love. The better the ingredients, the better the taste.
    • Smooth is Key: For a silky, smooth texture, ensure that the peanut butter and frosting are thoroughly combined. Any lumps can affect the final texture of your fudge.
    • Consistent Microwave Heating: Microwave in short bursts and stir in between. This prevents overheating and ensures the mixture combines well without burning.
    • Even Spreading: When transferring the mixture to the pan, take a moment to spread it evenly. This helps the fudge set uniformly, making it easier to cut into neat, equal pieces.
    • Patience in Setting: Allow enough time for the fudge to set properly. Rushing this process can result in a fudge that’s too soft or doesn’t hold its shape well.
    • Clean Slicing: For clean, sharp cuts, use a knife warmed under hot water and then dried. This makes slicing through the fudge easier, especially if it’s been chilled.

Cuisine American
  • Chocolate Frosting Substitute: For a chocolate twist, replace vanilla frosting with chocolate frosting. It adds a rich, chocolaty dimension to the fudge.
  • Almond Butter Alternative: If you’re not a fan of peanut butter or have allergies, almond butter is a great substitute. It offers a different nutty flavor while keeping the texture creamy.
  • Replace the Frosting: If you don’t want to use frosting but still want some really amazing PB fudge try my 3 ingredient recipe that uses butter and powder sugar.
  • Crunchy Peanut Butter: For a bit of texture, use crunchy peanut butter instead of creamy. It adds little bits of peanuts for an extra crunch in every bite.
  • Add Nuts: Stir in chopped nuts like walnuts, pecans, or almonds for added texture and flavor.
  • Sea Salt Topping: Sprinkle a bit of sea salt over the top of the fudge before it sets for a sweet and salty flavor profile.
  • Swirl in Jam or Jelly: Before the fudge sets, swirl in a bit of your favorite jam or jelly for a fruity flavor burst.
  • Vegan Adaptation: Use a dairy-free and vegan-friendly frosting along with natural peanut butter to make this recipe vegan.
  • Protein-Packed: Stir in a scoop of your favorite protein powder for an extra protein kick.

Add a Quick Chocolate Ganache Topping

Ingredients:

Semi-sweet chocolate chips or a chocolate bar (chopped): 1 cup
Heavy cream: ½ cup

Instructions:

  1. Heat the Cream: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Be careful not to boil it.
  2. Melt the Chocolate: Place the chocolate chips or chopped chocolate in a heatproof bowl. Once the cream is heated, pour it over the chocolate. Let it sit for about 1 minute to soften the chocolate.
  3. Whisk Together: After a minute, whisk the cream and chocolate together until smooth and glossy.
  4. Apply to Fudge: Pour the ganache over the peanut butter fudge before it sets. Spread evenly with a spatula.
  5. Let the ganache set along with the fudge.

How to Store 2 Ingredient Peanut Butter Fudge

  • Room Temperature: Store the fudge in an airtight container at room temperature if your house isn’t too warm. It’s best to place a piece of parchment paper between layers to prevent sticking.
  • Refrigerator: For a firmer texture, you can store the fudge in the refrigerator. Again, use an airtight container with parchment paper between layers.

Can I Freeze Peanut Butter Fudge?

What to Serve with PB Fudge

  • Coffee or Tea: The rich flavor of the fudge pairs wonderfully with a hot cup of coffee or tea. The bitterness of coffee or the subtlety of tea can complement the sweetness of the fudge.
  • Ice Cream: 3 Ingredient vanilla ice cream alongside the fudge makes for a classic dessert pairing. The light creaminess of the ice cream works well with the dense texture of the fudge.
  • Fresh Fruits: Serve the fudge with a side of fresh fruits like strawberries, bananas, or raspberries. The fruit’s natural acidity and sweetness balance the richness of the fudge.
  • Whipped Cream: A dollop of whipped cream on top of the fudge adds a light, airy texture and a touch of creaminess.
  • Nut Assortment: A small bowl of mixed nuts, like almonds, walnuts, or pecans, can be a great side to nibble on, offering a crunchy contrast to the fudge’s smooth texture.
  • Cheese Board: For a more sophisticated twist, pair the fudge with a cheese board featuring milder cheeses like Brie or Camembert, which won’t overpower the fudge’s flavor.
  • Milk: For a comforting and classic pairing, serve the fudge with a glass of cold milk. It’s a combination that’s sure to please all ages.

Frequently asked questions

Why isn’t my fudge setting?

If your fudge isn’t setting, it could be due to not mixing the ingredients thoroughly or not allowing enough time for it to cool and set. Make sure to mix the peanut butter and frosting well and allow ample setting time, preferably in a cool environment or in the refrigerator.

My fudge is too soft. What can I do?

Soft fudge usually indicates it needs more time to set. Place it in the refrigerator for a few hours. If it’s still too soft, it might be due to the type of frosting or peanut butter used; some brands can be softer than others.

My fudge has lumps in it. What went wrong?

Lumps often form if the peanut butter and frosting aren’t mixed well enough. Ensure you stir the mixture thoroughly until it’s completely smooth before setting.
