Ingredients
  

Peanut Butter

  • Why it's essential: The creamy texture and rich flavor of peanut butter are what make this fudge so irresistible. It’s the base that gives the fudge its melt-in-your-mouth consistency.
  • Tip: For the smoothest fudge use creamy peanut butter. Natural or chunky peanut butter can work too, but they might change the texture slightly.
  • Amount: 1 cup of peanut butter will give you the perfect consistency.

Butter

  • Why it's essential: Butter adds richness and helps bind the fudge together giving it that creamy, meltable quality.
  • Tip: Use unsalted butter to control the sweetness. If you're dairy-free you can substitute with coconut oil for a different twist (and a slight coconut flavor!).
  • Amount: 1/4 cup of butter about half a stick will be just the right amount.

Powdered Sugar

  • Why it's essential: This is the magic ingredient that sweetens the fudge without giving it a gritty texture. Powdered sugar dissolves easily into the peanut butter and butter creating a smooth and creamy finish.
  • Tip: Sift the powdered sugar before adding it to avoid any lumps. If you prefer a less sweet fudge you can reduce the amount slightly.
  • Amount: 2 cups of powdered sugar will give you the perfect sweetness and consistency.

Instructions
 

Melt the Peanut Butter and Butter

  • Step 1: In a medium saucepan, add 1 cup of creamy peanut butter and 1/4 cup of butter (unsalted).
  • Step 2: Heat the mixture over medium heat, stirring consistently until both the peanut butter and butter have completely melted and blended together. This process should be quick, so keep an eye on it and stir to avoid any burning.
  • Pro Tip: If you’re short on time, you can microwave the peanut butter and butter in a microwave-safe bowl for about 30 seconds, then stir until smooth.

Incorporate the Powdered Sugar

  • Step 1: Once the peanut butter and butter have fully melted, remove the pan from the heat.
  • Step 2: Gradually add 2 cups of powdered sugar to the mixture, stirring constantly to incorporate it evenly. The sugar will dissolve into the peanut butter and butter, forming a thick, smooth base.
  • Pro Tip: For an extra smooth texture, consider using a hand mixer on low speed, but be careful not to overmix.

Pour into a Pan and Set

  • Step 1: Line an 8x8-inch baking dish with parchment paper or lightly grease it to prevent the fudge from sticking.
  • Step 2: Pour the peanut butter mixture into the prepared pan, spreading it evenly with a spatula or spoon.
  • Pro Tip: To create a smooth, clean top, use another piece of parchment paper to gently press down on the fudge, helping to eliminate any air pockets.

Chill Until Firm

  • Step 1: Place the pan in the refrigerator and allow the fudge to chill for at least 2 hours, or longer if possible. The fudge will firm up during this time, making it easier to cut into squares.
  • Pro Tip: If you’re in a rush, the freezer works too! Just pop the pan in for about 30-45 minutes for a quicker set, but be sure not to leave it for too long to avoid overhardening.
