Ingredients

  • 110 g (1/2 cup) coconut cream or heavy cream, *see note 1
  • 113 g (1/2 cup) butter plant-based, regular, ghee, or coconut oil
  • 272 g (1.5 cups) sweetener of choice I used a stevia & erythritol blend by Nkd Living, see note 2 for link
  • 216 g (3/4 cup) natural peanut butter (100% nuts) or almond butter
  • 1 tsp vanilla
  • 1/8 tsp salt skip if using salted butter

Instructions

  • Line an 8x8 baking dish with parchment paper or greaseproof paper and set it aside.
  • Add the coconut cream, butter, and sweetener to a pot over medium heat and heat until everything melts together and there are no granules of sweetener left.
  • Turn off the heat and mix in the peanut butter, vanilla, and salt.
  • Pour the mixture into the lined baking dish and allow it to cool to room temperature.
  • Once cooled, place it in the fridge for 2 hours or until firm.
  • Slice with a hot knife (for clean lines) and enjoy!

Notes

  1. The solid part from the top of a chilled can of coconut milk
  2. The Stevia & Erythritol Blend I used can be found here: https://amzn.to/3GhhT6d
  3. Keto Chocolate Peanut Butter Fudge: Add sugar-free chocolate chips to this keto fudge recipe. Chocolate + peanut butter is heaven!
  4. To make this creamy fudge paleo, use another nut butter like almond butter (peanuts are a legume and therefore not paleo), ghee or coconut oil instead of butter, and a paleo-friendly sweetener like stevia, monk fruit, or coconut sugar. It will no longer be keto if you use coconut sugar. Sprinkle with a little sea salt at the end to really make those flavors pop!
  5. Store this sugar-free traditional peanut butter fudge in an airtight container in the fridge for up to a week.
  6. Freeze in a sealed container for up to 3 months. Eat thawed or frozen.
