2-Ingredient Peanut Butter Fudge That Never Fails

2-Ingredient Peanut Butter Fudge is proof that dessert does not need complexity to feel special. Creamy, smooth, and deeply peanut-buttery, this no-bake treat delivers rich flavor with almost no effort. With nothing more than vanilla frosting and creamy peanut butter, you can create a sliceable fudge that looks polished, tastes indulgent, and fits perfectly into busy schedules.

This 2-Ingredient Peanut Butter Fudge is especially ideal when time is short but expectations are high. There is no oven to preheat, no thermometer to watch, and no tricky timing to manage. Instead, you mix, chill, and enjoy. Whether you are filling holiday tins, preparing a quick gift, or simply craving something sweet in the afternoon, this recipe answers the call with ease.

I first made this fudge on a hectic afternoon when I wanted something comforting without creating a mess. I stirred the two ingredients together, pressed the mixture into a pan, and slid it into the fridge. A short while later, I had neat little squares of creamy fudge that tasted far more indulgent than the effort suggested. Since then, it has become my most reliable no-bake sweet, especially when I want guaranteed success.

Why This Fudge Works So Well

Two Ingredients That Balance Each Other

The magic behind 2-Ingredient Peanut Butter Fudge lies in how the ingredients complement one another. Vanilla frosting provides sweetness and structure, while peanut butter adds richness and depth. Together, they create a smooth, stable fudge that sets beautifully without cooking.

Because the frosting already contains sugar and fat in the right proportions, it eliminates the need for candy-making techniques. Meanwhile, the peanut butter tones down the sweetness, preventing the fudge from becoming cloying. As a result, every bite tastes balanced and satisfying.

Foolproof Texture Every Time

Texture can be tricky with traditional fudge, but this recipe removes the guesswork. There is no risk of graininess or separation. As long as the mixture is stirred until smooth, the fudge sets with a creamy, sliceable consistency.

Additionally, chilling rather than baking keeps the texture dense yet soft. Once set, the fudge holds its shape well, making it easy to cut into clean squares. That reliability is exactly why 2-Ingredient Peanut Butter Fudge works so well for gifting and make-ahead desserts.

Ingredients That Make It Happen

What You Need and Why It Matters

This recipe calls for just two ingredients:

Vanilla frosting
Creamy peanut butter

The frosting acts as both sweetener and binder. Choose a standard shelf-stable vanilla frosting for best results, as it has the consistency needed to set properly. Homemade frosting can work, but it often varies in texture.

Creamy peanut butter blends smoothly into the frosting, creating a uniform mixture. Natural peanut butter is not recommended here because the oil separation can affect the final texture. For consistent results, stick with a classic creamy style.

Optional Finishing Touches

Although 2-Ingredient Peanut Butter Fudge is complete as written, small finishing touches can elevate it. A light sprinkle of flaky salt on top adds contrast and enhances the peanut flavor. Pressing the mixture into cupcake liners creates perfectly portioned bites for sharing.

However, these additions are optional. The beauty of this recipe is how complete it feels with just two ingredients. That simplicity keeps it approachable and stress-free.

How to Make It Perfectly Smooth

Mixing the Fudge Base

Start by placing both ingredients in a microwave-safe bowl. Gently warming the mixture makes it easier to stir, but avoid overheating. Short bursts with stirring in between work best.

Once warm, stir steadily until the mixture becomes smooth and glossy. This step matters because even mixing ensures the fudge sets evenly. Take your time here, since proper blending is the key to a creamy finish.

Setting and Cutting

Line a small pan with parchment paper before pressing in the mixture. This makes removal easy and keeps the edges clean. Use a spatula to smooth the top evenly.

Chill the fudge until firm. Once set, lift it out using the parchment and cut into squares with a sharp knife. Wiping the blade between cuts helps keep edges neat. With these simple steps, 2-Ingredient Peanut Butter Fudge looks as good as it tastes.

When to Serve and How to Store

Perfect for Gifting and Sharing

This fudge is ideal for gifting because it travels well and keeps its shape. Stack squares in decorative boxes or arrange them in tins with paper liners. Because it does not melt easily, it works well for holiday exchanges and bake sales.

It also shines on dessert trays. The smooth, pale peanut butter color stands out among cookies and chocolate treats. Guests appreciate its rich flavor and soft texture, especially alongside coffee or tea.

Storage Tips

Store 2-Ingredient Peanut Butter Fudge in an airtight container in the refrigerator. It stays fresh for up to a week, and the texture actually improves after a day as it firms slightly.

For longer storage, freeze the fudge in a sealed container. Thaw it in the refrigerator before serving. Because it contains no baked elements, the texture remains smooth even after freezing.
