Gathering these straightforward, pantry-friendly ingredients sets you up for success. Each one plays a crucial role, from the silky sweetness of the condensed milk to the fluffy texture imparted by the marshmallow cream, resulting in a perfectly balanced peanut butter fudge experience.

  • 10 oz. peanut butter chips: These provide that authentic peanut butter flavor and smooth texture; white chocolate chips can also be a delightful alternative.
  • 1 can sweetened condensed milk (14 oz.): This is the magic liquid sweetener that brings creamy richness and helps the fudge set perfectly.
  • ⅓ cup creamy peanut butter: Adds extra depth and that signature nutty goodness, boosting flavor and creaminess.
  • 1½ teaspoons vanilla extract: Enhances the overall flavor profile with a delicate warm note.
  • ⅔ cup marshmallow cream: The secret ingredient for that irresistible fluffy, creamy texture in the fudge.
  • 1 cup mini marshmallows (optional): Toss these in if you want extra gooey marshmallow bites inside your fudge.

How to Make Easy 5-Minute Microwave Peanut Butter Fudge with Marshmallow Cream Recipe

Step 1: Melt Peanut Butter Chips and Condensed Milk

In a microwave-safe bowl, combine the peanut butter chips and sweetened condensed milk. Microwave on high in 20-second intervals, stirring well after each burst. This gradual melting ensures a smooth, velvety mixture without burning the chips. It usually takes about 1 to 1½ minutes total for everything to blend into a luscious base.

Step 2: Incorporate Peanut Butter and Vanilla

Once your chocolate-peanut butter combo is silky and fully melted, stir in the creamy peanut butter and vanilla extract. This step layers in that rich, nutty character and a subtle floral tone from the vanilla, making the fudge taste truly irresistible.

Step 3: Fold in Marshmallow Cream and Optional Mini Marshmallows

Gently stir in the marshmallow cream until just combined—this keeps the fudge light and fluffy instead of dense. If you love marshmallows like I do, now’s the time to fold in those mini marshmallows for delightful bursts of chewy sweetness throughout the fudge.

Step 4: Set and Chill

Transfer your mixture to an 8×8 inch pan lined with parchment paper or greased well to avoid sticking. Spread it evenly to ensure consistent thickness. Pop it in the fridge to chill until fully set, which usually takes a couple of hours. The waiting is worth it because once firm, the fudge slices beautifully and melts on your tongue.

This fudge pairs beautifully with a steaming cup of coffee or hot chocolate, perfect for cozy afternoons or dessert after dinner. For a refreshing contrast, serve with fresh raspberries or sliced apples, whose tartness cuts through the richness splendidly.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Keep your fudge fresh by storing it in an airtight container in the refrigerator. It will stay delicious for up to two weeks, making it a perfect make-ahead treat that’s ready whenever you need a quick indulgence or unexpected guests arrive.

Freezing

If you want to save fudge for longer, freezing works wonderfully. Wrap individual pieces tightly to prevent freezer burn. When you’re ready to enjoy, thaw them overnight in the fridge for a soft, creamy texture that tastes just like freshly made.

Reheating

Though fudge is best enjoyed chilled, if you prefer it softer, allow it to sit at room temperature for about 15 minutes before indulging. Avoid microwave reheating as it can change the texture; patience really pays off here for the best melt-in-mouth experience.

FAQs

Can I use natural peanut butter for this recipe?

Natural peanut butter tends to separate and may affect the texture of the fudge. For best results, stick to creamy, stabilized peanut butter varieties to maintain smoothness and consistency in your Easy 5-Minute Microwave Peanut Butter Fudge with Marshmallow Cream Recipe.

What if I don’t have marshmallow cream? Can I substitute something else?

Marshmallow cream adds unique fluffiness, but in a pinch, some melted marshmallows can work similarly. Just melt and cool slightly before folding in. Keep in mind, the texture might be a little different, but still delicious.

Why is it important not to over heat or over stir the fudge?

Overheating can make the fudge dry and clumpy, while over stirring can cause a grainy texture. For the smoothest, creamiest fudge, gently melt and carefully fold ingredients only until just combined—this technique preserves that luscious mouthfeel.

Can I make this fudge without a microwave?

Yes! Use a double boiler on the stovetop to melt the peanut butter chips and condensed milk slowly, stirring frequently. Just be patient and gentle to prevent overheating, and then proceed with the rest of the recipe steps.

How should I cut the fudge for the best results?

For clean, smooth cuts, use dental floss or a thin, sharp knife warmed slightly under hot water, wiping dry before each slice. This helps you get neat, attractive fudge squares without sticking or crumbling.

Ingredients

Fudge Ingredients

  • 10 oz. peanut butter chips (white chocolate can be substituted)
  • 1 (14 oz.) can sweetened condensed milk
  • ⅓ cup creamy peanut butter
  • 1½ teaspoons vanilla extract
  • ⅔ cup marshmallow creme
  • 1 cup mini marshmallows (optional)

Instructions

  1. Combine and Melt: In a microwave-safe bowl, combine the peanut butter chips and sweetened condensed milk. Microwave on high for 20-second increments, stirring in between each until the chips are fully melted and the mixture becomes smooth and creamy. This should take about 1 to 1½ minutes.
  2. Add Peanut Butter and Vanilla: Stir in the creamy peanut butter and vanilla extract until completely blended with the melted chips and condensed milk mixture.
  3. Incorporate Marshmallow Cream: Gently fold the marshmallow creme into the fudge mixture just until incorporated, to maintain a light, creamy texture. If using, fold in the mini marshmallows at this stage.
  4. Set the Fudge: Transfer the mixture to an 8×8 inch pan lined with parchment paper or well-greased for easier removal. Spread the fudge evenly and chill in the refrigerator until firmly set.

Notes

  • Do not overheat or over-stir the fudge mixture to avoid a grainy texture and prevent the fudge from becoming dry or clumpy.
  • Ensure you use sweetened condensed milk, not evaporated milk, as evaporated milk will not produce the correct fudge consistency.
  • For smooth, clean cuts, use dental floss or a knife warmed in hot water and dried before slicing the fudge.
