My mom and grandma always worked feverishly in their kitchens around the holidays. They’d whip up batches of their famous peanut brittle that required precise temperatures and even spatulas or it would flop.

Fortunately, Peanut Butter Fudge is foolproof! It has the creamiest texture and can’t-keep-my-hands-off-it quality that keeps you coming back for more!

I love all fudge at the holidays, including this classic chocolate fudge and vanilla fudge, but none can stack up to the sweet and salty creaminess ofthis fudge!

Two ingredients make this fudge recipe stand above the rest – milk and powdered sugar. It gives it the creamiest, dreamiest crowd-pleasing texture!

This Peanut Butter Fudge recipe is incredibly quick and easy to make. It takes just 10 minutes, six staple ingredients and a little patience to solidify before you enjoy. That’s the most difficult part for me, waiting!

It’s so good that I recommend you have a share plan in mind. It’s seriously addictive.

Even better, this fudge doesn’t require any special tools or candy thermometers. It is made in a baking dish like the same square pan you use to make brownies. Honestly, it’s so SIMPLE! It’s a great no bake dessert!

Ingredients and Substitutions

It’s made with staple ingredients you likely already have in your pantry!

  • Butter – salted or unsalted, your preference.
  • Brown Sugar – this ingredient offers beautiful color and a hint of molasses flavor.
  • Whole Milk – or half and half, one reader even mentioned using skim, though I haven’t tested it.
  • Peanut Butter – use creamy, but avoid using natural. It has an entirely different consistency that doesn’t play well with fudge and allow it to solidify.
  • Vanilla – I like to use Homemade Vanilla Extract, but any vanilla will do!
  • Powdered Sugar – also known as confectioner’s sugar, this maintains that smooth, creamy consistency that’s synonymous with peanut butter fudge.

Variations

  • Add nuts
  • Swirl it into chocolate fudge
  • Add marshmallows
  • Add chocolate chips
  • Cover in melted chocolate to make Buckeye Fudge – seriously, it tastes exactly like Buckeyes!
  • Substitute coconut milk for the Whole Milk for a different flavor profile and less dairy.

Frequently Asked Questions

Why won’t my peanut butter fudge harden?

Often this means that your ingredients need to be cooked down a little longer, or to a higher temperature. If this happens, try reheating your peanut butter fudge by adding a little more milk and bringing it back to a slow boil.

Why is my peanut butter fudge oily on top?

If your fudge shows oil on the top, it could actually be that you are overcooking or simply over-stirring. Use a gentle hand with very minimal stirring and allow the ingredients to come to a slow boil.
