Simple Peanut Butter Fudge Ingredients 

Typically, fudge recipes are made with loads of sugar and butter. Don’t get me wrong, they’re totally delicious. However, from day to day, I prefer my sweets to be a little more nourishing. Know what I mean? So, I took the original recipe and made it even better with whole food ingredients you can feel good about eating! Here’s what you’ll need: 

  • Peanut Butter – I know there’s a big debate between crunchy and smooth peanut butter lovers, but just trust me. You’re gonna want crunchy. Mkay? 
  • Coconut Oil – Used to replace butter, coconut oil helps create combine the ingredients and provide the rich taste we love. 
  • Protein Powder – Don’t skip this! I found that Nuzest vanilla pea protein works best (Feel free to use code: thekellykathleen). However, feel free to experiment with whatever you like best. 
  • Peanuts – Mixing in whole peanuts takes the peanut butter flavor to the next level and adds an extra crunch you’ll love.
  • Sea Salt – Just a pinch of salt helps enhance the rest of the flavors. 

How to Make Easy Peanut Butter Fudge

Not to toot my own horn, but this might be the easiest peanut butter fudge recipe you’ll ever make!

  1. Combine all of the ingredients. 
  2. Line a small baking dish with a piece of parchment paper. 
  3. Pour the fudge mixture into the dish. 
  4. Freeze for at least an hour. 
  5. Let the fudge come to room temperature for 15-20 minutes.
  6. Slice it into pieces (preferably large ones), and dig in! 

Optional Add-Ins

Personally, I love the simplicity of this recipe. However, if you want to add a little extra flavor, feel free to experiment with additional add-ins! Some of my favorite options include: 

Chocolate Chips. Folding in a few chocolate chips makes for a classic chocolate and peanut butter combination. 

Candy Pieces. Break up your favorite candy like Reese’s or Butterfingers for an extra decadent dessert. 

Chopped Pretzels. If you’re a fan of salty flavors, try chopping up a few pretzels to add to the batter. 

Sprinkles. I’m pretty sure sprinkles can go in anything. They don’t add a ton of flavor, but they make everything pretty and so fun to eat! 

How to Store

I’ve never heard of anyone having leftover peanut butter fudge. However, if you do, it keeps well and can be stored 3 ways! 

Room Temperature: Store in an airtight container for 2-3 days

Refrigerator: Layer your fudge between pieces of parchment paper, and keep them in the fridge for 2-3 weeks

Freezer: For the longest-lasting results, place your peanut butter fudge in the freezer for p to 2-3 months
