Peanut Butter Chocolate Fudge Ingredients

You will find a full printable recipe card at the bottom of this post, but here's a quick peek at what you'll need to make this delicious fudge. You only need a handful of simple ingredients.

• 1 (14-ounce) can sweetened condensed milk
• 1 cup chocolate chips
• 1 cup peanut butter (plus 2-3 tablespoons for swirling)
• 1 teaspoon vanilla extract (optional)
• Pinch of salt (optional)

The vanilla and salt help deepen the flavor but can be omitted if you prefer.

How to Make Microwave Peanut Butter Chocolate Fudge

Line an 8x8 baking pan with parchment paper or foil. This makes it easy to remove the fudge later.

Place the sweetened condensed milk and chocolate chips in a large microwave-safe bowl.

Microwave for 1 minute, then stir.

Return the bowl to the microwave and heat for another 30–45 seconds, until the chocolate melts completely when stirred.

Add the peanut butter, vanilla, and salt. Stir until the mixture becomes smooth and glossy.

Pour the fudge mixture into the prepared pan and spread evenly.

Optional Peanut Butter Swirl

For a little extra peanut butter flavor, try adding a swirl on top.

Warm 2 tablespoons peanut butter in the microwave for about 10 seconds, drizzle it over the fudge, and swirl gently with a knife before chilling.

This simple step gives the fudge a beautiful homemade candy-shop look. It also adds another layer of peanut butter flavor on top, which is delicious!

Refrigerate for 2–3 hours, or until the fudge is firm.

Lift from the pan and cut into squares.

Serve and Enjoy!

Fun Add-Ins

This recipe is easy to customize. Try mixing in:

• chopped peanuts (about ⅓ cup)
• mini marshmallows (or dehydrated marshmallows)
• crushed pretzels (yum!)
• peanut butter chips (perfection!)
• top with chopped Reese's Peanut Butter cups for a full-on decadent treat!

Storage Tips

Store fudge in an airtight container.

Refrigerator: up to 2 weeks
Freezer: up to 3 months

If freezing, place parchment between layers so the pieces don’t stick together.
