  • 3.5 quart slow cooker or larger
  • mixing spoons
  • slow cooker liner or parchment paper (optional)
  • rubber spatula or knife for smoothing
  • sharp knife


  • 20 oz peanut butter baking chips
  • 1 cup smooth peanut butter
  • 1 cup chunky peanut butter
  • 2 teaspoon vanilla
  • pinch of salt


  • place slow cooker liner or parchment paper into slow cooker
  • add peanut butter chips, peanut butter vanilla and salt into slow cooker
  • cover and cook on high for 30 minutes
  • after 30 minutes, stir to mix ingredients, place lid back on slow cooker and continue to cook
  • every 15 minutes after the initial 30, open slow cooker and stir ingredients to make sure sides and bottom don't burn and that everything is fully melted and combined. Depending on your slow cooker, this process should take a total of 45-90 minutes.
  • Once all ingredients are fully melted and stirred together, use a knife, or spatula to smooth out into a flat surface, turn off slow cooker and allow to cool and harden. You can carefully remove slow cooker insert from heating element to help speed up this process.
  • If you would like to add toppings or decorations like those in the photos, they should be added once the mixture starts to thicken a bit (so they don’t sink) but before the fudge has fully set so toppings will stick.
  • once fudge has fully set, lay on a flat surface and use a sharp knife to cut into squares for serving.


**Please note calorie count was calculated for one small square of fudge and does not include any toppings.
