There is something deeply nostalgic about a perfect square of homemade fudge. While traditional recipes often involve candy thermometers, precise boiling points, and the constant fear of crystallization, this Easy Peanut Butter Fudge changes the game entirely. Imagine a dessert that boasts a silky-smooth texture, a rich nutty aroma, and a melt-in-your-mouth finish—all achieved with just two primary ingredients and a few minutes of effort.

Whether you are looking for a quick last-minute dessert, a thoughtful homemade gift, or a protein-packed sweet treat to keep in the fridge, this recipe is the gold standard. It’s dense, decadent, and strikes the perfect balance between salty and sweet.

The Anatomy of Perfection: Ingredients

• Creamy Peanut Butter (18 oz): This is the heart of the dish. Peanut butter provides the fat content necessary for that signature “fudge” feel. We recommend using a standard stabilized brand (like Jif or Skippy) rather than “natural” varieties that separate, as the added oils in processed peanut butter ensure a consistent, emulsified texture that sets firmly.
• Vanilla Frosting (16 oz Can): This is the “secret weapon” of professional-grade easy fudge recipes. The frosting acts as the sweetener and the binding agent. Because it is already aerated and contains stabilizers, it allows the fudge to set with a velvety crumb that isn’t grainy, bypassing the need for heavy cream or powdered sugar.

Step-by-Step Instructions

1. Prepare Your Pan

Line an 8×8-inch baking dish with parchment paper, leaving a slight overhang on the sides. This “sling” method allows you to lift the entire block of fudge out once set, ensuring clean, sharp edges when slicing.

2. Melt and Combine

In a large, microwave-safe glass bowl, add your creamy peanut butter. Microwave it in 30-second intervals until it is warm and fluid. Next, remove the lid and foil seal from your vanilla frosting and microwave the frosting for about 30-45 seconds until it reaches a pourable, liquid consistency.

3. The Emulsion Process

Quickly pour the melted frosting into the bowl with the peanut butter. Using a sturdy spatula, fold the two together until the color is uniform and no white streaks remain. Pro Tip: Work quickly, as the mixture will begin to “seize” and set as it cools!

4. The Set

Pour the mixture into your prepared pan and smooth the top with an offset spatula. Tap the pan firmly on the counter a few times to release any trapped air bubbles. Place the pan in the refrigerator for at least two hours (or the freezer for 30 minutes) until firm to the touch.

Serving and Storage Suggestions

This Peanut Butter Fudge is a versatile powerhouse. Serve it alongside a bitter espresso to balance the sweetness, or crumble it over vanilla bean ice cream for a decadent sundae. For storage, keep the fudge in an airtight container in the refrigerator for up to two weeks.
