Chocolate and peanut butter is a classic combination that just can’t be beat. When you put those flavors into fudge form, it’s even more delicious! This chocolate peanut butter fudge is simple to make and will satisfy even the biggest chocolate craving.

How do you make chocolate peanut butter fudge?

This fudge starts with the chocolate layer, which is made of chocolate chips, condensed milk and butter. Everything gets heated together in the microwave and the fudge is spread into the bottom of the pan.

If your chocolate fudge mixture looks a little grainy at first, don’t worry about it. As you spread it into the pan it will smooth out. Just be be sure to firmly press the fudge into the bottom of the pan so that it forms an even layer. I like to use an offset spatula for this step.

The next step is to chill the chocolate fudge so that it’s fully set before you add your peanut butter layer. The peanut butter layer is made with peanut butter, butter and powdered sugar. It starts out quite liquid, but as it chills it will firm up into a delicious melt-in-your mouth fudge.

The peanut butter cups go over the top, and the whole pan goes into the fridge to chill until firm. Lining the pan with foil makes it much easier to remove the whole slab of fudge for slicing later on.

What is the difference between chocolate and chocolate fudge?

Chocolate bars and chocolate fudge have similar flavors, but the difference is in the texture and the ingredient list. Fudge is softer, sweeter, and always contains ingredients like butter or sweetened condensed milk. Chocolate bars do not contain butter or condensed milk and are firm in texture.

After your fudge is chilled, simply cut into small squares and serve! This is a rich treat, so I cut my fudge into 36 small pieces.

I make this chocolate peanut butter fudge every year for the holidays, it’s a family tradition! It always gets rave reviews from friends and family.

    1. The recipe calls for a 9 inch square pan which is the same as a 9×9. The fudge will be super thin in a 9×13, I wouldn’t recommend it.

  1. I’m so sorry that happened, I haven’t seen this happen before! You should make sure there isn’t any butter or greasy residue left on top of the chocolate layer. That could potentially cause the peanut butter layer not to stick to the chocolate.

  2. Hi! This recipe looks amazing and I can’t wait to try! Quick question: the recipe calls for 7 oz sweetened condensed milk- 1/2 of a standard size can but under recipe notes it states “the amount of sweetened cond milk in this recipe is the equivalent of one 14 oz can. Can you clarify the amount of sweetened condensed milk? Thank you!

  3. Oh my goodness! Those PB cups on top have taken this treat over the edge! Love this treat!

  4. 5 stars
