Peanut Butter Candy

I've literally made a version of this about 12 times trying to nail it! I finally did and now am sharing with all of you! This has everything you are hoping for... creamy, sweet, chocolatey, and does not crumble! It is the perfect balance of flavors. It is also wonderful for making buckeyes for the holidays!

Peanut Butter Fudge

  • 2 cups peanut butter no sugar added
  • 1/2 stick butter salted
  • 1 tsp vanilla extract
  • 1 cup whey powder unflavored
  • 2 cups Swerve powdered
  • 1/2 tsp sea salt

Chocolate Topping

  • 1/2 cup Heavy Whipping Cream
  • 1 cup Chocolate Chips Lily's
  • 1.5 cups Swerve powdered
  • 2 tbsp butter salted
  • 1/2 tsp vanilla extract


  • Gently melt butter (stovetop or microwave, whichever you prefer). Remove from heat.
  • Add in peanut butter, vanilla, whey, and powdered Swerve (or powdered erythritol), and sea salt. Mix hard until it is well combined.
  • Pour peanut butter fudge into a 12 x 16 cookie sheet with, at least, a 1-inch lip around the pan. We line ours with parchment paper.
  • Gently warm the heavy whipping cream in a large bowl. Remove from heat and add the chocolate chips. Allow to sit for about 30 seconds so the chocolate chips can melt. Stir to combine.
  • Add vanilla and room temp (or melted) butter and powdered Swerve. Stir to combine and pour over peanut butter fudge.
  • Place in refrigerator and allow to set up for, at least, an hour. The longer it sets up the better it tastes and holds together.  We find it is the best the following day.

We absolutely love this cookie sheet and use it especially for making our peanut butter candy.
Important Note: You can make just the peanut butter part and serve as peanut butter fudge -- so, so good!
This is not something I would make on a regular basis but would be fantastic for holiday events! You can definitely make Southern Buckeyes out of these.
We do not include the carbs from sugar alcohol sweeteners (such as Swerve, Lakanto, or Erythritol), as they have zero net carbs and have been shown to not raise blood sugar levels.
