I never really make fudge at home. It's usually found when my family visits quaint little towns for mini vacations. There is usually a gourmet confection shop where the boys want to try everything, including some fudge. When I started researching how easy it actually is to make fudge, I decided to try out this Chocolate Peanut Butter Fudge recipe for our holiday treat boxes this year, and I'm so happy I did. It's the perfect little indulgent bite and so easy to make! The peanut butter swirl and flaky salt make it look like they came from one of those dreamy shops we love so much! This fudge is great paired with my Chocolate Covered Potato Chips , Pretzel Christmas Crack, and Chocolate Covered Graham Crackers for an easy holiday treat box.

Charlotte's Tips for making the best Peanut Butter and Chocolate Fudge
- Microwave-safe bowls and silicone spatulas make this super smooth and easy to stir.
- Stop microwaving once most of the chips are melted; the residual heat will finish the job.
- For a cleaner swirl, warm the peanut butter just enough to drizzle smoothly.
- Use a butter knife, skewer, or toothpick to swirl vertically for that signature look.
- Refrigerate uncovered until firm, then cover for storage.
Recipe Variations
- Top with crushed pretzels or flaky sea salt for sweet & salty vibes.
- Add a sprinkle of mini chocolate chips or holiday sprinkles after swirling.
- Swirl in cookie butter or Nutella for a different flavor option.
- Use white chocolate chips and swirl with peanut butter for a different look.
Recipe Substitutions
- Use almond butter, cashew butter, or sunflower seed butter if you would like to swap out the peanut butter.
- Swap semi-sweet chocolate chips with dark or milk chocolate for different sweetness levels.
- If you’re out of butter, coconut oil works as a 1:1 substitute.

You can also freeze it for up to 2 months; place squares in a single layer, freeze, then transfer to a bag or container. Thaw overnight in the fridge before serving.
