Ingredients for 4 ingredient peanut butter fudge

INGREDIENTS 

  • Peanut butter- I typically use American Nut Butter (my favorite nut butter brand). If i’m grabbing a peanut butter from the grocery store, I’ll grab Smart Balance or Simple Truth creamy peanut butter. I would recommend a salted, drippy, natural peanut butter here if possible. Also a creamy peanut butter, as opposed to a crunchy peanut butter. You can use a more solid (less drippy) peanut butter here too, you may just need to microwave it so it’s easier to stir and work with.
  • Maple syrup – I used sugar free. You can use pure maple syrup or honey here. Use pure maple syrup for vegan.
  • Coconut oil
  • Vanilla extract – to bring out the flavor of everything more!
  • Optional toppings – chopped Reese’s cups are delicious on this fudge but you could also do chocolate chips, pretzels, peanuts, chopped Twix, etc.
How to make 4 ingredient peanut butter fudge (process steps)

HOW TO MAKE 4 INGREDIENT PEANUT BUTTER FUDGE

  1. Line a small 8×4-inch pan with parchment paper (or use a 8×8 square pan and only spread out as thin as you want the fudge to be). 
  2. Add the peanut butter, coconut oil, maple syrup and vanilla to a large bowl and mix together until smooth. If you are using peanut butter that is not very drippy, you will want to microwave everything together so it’s more drippy and spreads easier. 
  3. Transfer the peanut butter mixture into the prepared pan and smooth the top of the fudge mixture out as best as you can with the back of a spatula or wooden spoon. Add to the freezer for 10 minutes to firm up slightly then sprinkle the chopped Reese cups on top (if you are using). Freeze for 30 minutes to an hour or until firm.
  4. Then take out and cut into 18 small squares with a sharp knife. Depending on how long you froze the fudge, you may need to let it sit at room temperature for a few minutes before cutting. 

If you have a hard-to-stir solid peanut butter you might want to microwave it in a microwave-safe bowl with the coconut oil and syrup so it’s thinner and easier to work with.

4 INGREDIENT PEANUT BUTTER FUDGE: FAQ

What if I don’t have a drippy peanut butter?

No worries! Any kind of smooth peanut butter will work here! You may just want to microwave it in a microwave-safe bowl with the coconut oil and syrup so it’s thinner and easier to work with.

Can you use another nut butter besides peanut butter?

You can. Any nut butter will work here. Just know that the flavor of the fudge will completely change to whatever nut butter you use since it is the primary ingredient in this recipe.

Can you make this recipe gluten and dairy free?

Yes! This peanut butter dessert is gluten free as written, You will just want to double check that the Reese’s you are using are gluten free, if you are adding them (most of the varieties are!) Reese’s cups are not dairy-free though, so if you wanted to add a topping, you’ll need to find some dairy-free Reese’s or pick a different dairy-free topping.
