3-Ingredient Peanut Butter Fudge (Easy Microwave Recipe)

Why this shortcut fudge works

Peanut butter chips provide sweetness and structure, while the condensed milk helps create a cohesive mixture. Creamy peanut butter adds another layer of nutty flavor and blends into the melted chips.

The method is straightforward: melt gently, stir well, spread in a lined pan, and chill until firm. The finished texture should be creamy and sliceable. It is a different process from traditional cooked-and-beaten fudge, which requires more attention to sugar temperature.

• Three ingredients and one microwave-safe mixing bowl.
• No oven, candy thermometer, or powdered sugar needed.
• Easy to portion into small squares for sharing.

Choose the right three ingredients

Use sweetened condensed milk, not evaporated milk. The two canned products are different, and evaporated milk will not give this recipe the same sweetness or consistency.

Choose peanut butter baking chips rather than chocolate chips. Measure two cups; package weights vary by brand. A smooth, shelf-stable creamy peanut butter gives a more predictable result than an oily natural peanut butter that separates in the jar.

Tips for smooth fudge

Line the pan before melting anything. Leave enough parchment hanging over two opposite sides to use as handles once the fudge has set.

After the first microwave interval, stir thoroughly even if some chips still look solid. Residual heat helps melt them. Continue in short bursts only as needed; overheating can make the mixture thick or grainy.

Spread the mixture promptly and give it at least two hours to chill. If it still feels soft in the center, leave it longer rather than trying to cut it early.

Serving and gift ideas

For neat edges, lift the chilled slab onto a cutting board and use a sharp knife. Wipe the blade between cuts. Sixteen squares make generous portions, while twenty smaller pieces work well on a mixed dessert tray.

Place fully set pieces in mini paper candy cups or layer them between parchment in a small gift box. Let recipients know the fudge contains peanuts and dairy. Keep any optional toppings separate from the basic three-ingredient recipe.

How to store peanut butter fudge

Keep the fudge in a covered container in the refrigerator for up to one week. Separate stacked layers with parchment so the pieces stay tidy.

For longer storage, wrap portions tightly, place in a freezer-safe container, and freeze for up to two months. Thaw in the refrigerator before serving. A few minutes out of the refrigerator can soften very firm pieces, but avoid leaving the whole batch in a warm kitchen.
