BEST Peanut Butter Cookie Bars
These bars are amazing – it’s my favorite peanut butter cookie recipe topped with an EASY fudge! Obviously, I started with peanut butter cookies. Have you read this blog? It should be called Crazy for Peanut Butter.
These cookie fudge bars please everyone – the cookie and candy lovers alike. Plus: PB&C, you can’t go wrong.
I love that these chocolate fudge bars are made as cookie bars because, come on. Sometimes scooping cookie dough is just too hard. Bars are so much easier! Basically, you bake the cookie bars, let them cool, and then make an easy fudge recipe that spreads all over the top. Your entire family will love these bars!
They are a riff on these cookie fudge bars. When I made the funfetti version, I told myself every cookie needs a fudge topper. Am I right or am I riiiiiight?

How to Make Peanut Butter Chocolate Cookie Bars
1. Cream: Cream the butter, peanut butter, and both kinds of sugars in a large bowl with a hand mixer or in a stand mixer fitted with the paddle attachment.
2. Mix: Add the eggs, vanilla, milk, baking soda, and salt. Mix until combined, and then slowly add the flour and mix just until the dough comes together.
3. Bake: Press the dough into a prepared 9×13” baking pan. Bake at 350°F for 18 to 24 minutes or until golden. Let the peanut butter bars cool completely.
4. Fudge: Once the cookie bars are cooled, make the fudge topping. Place the chocolate chips and sweetened condensed milk in a saucepan. Heat them over low heat, frequently stirring, until smooth.
5. Top: Pour the mixture over the cooled bars and sprinkle the nuts and sprinkles over the top, if using. Let the fudge cool so it can set up before slicing the bars.
These are like having a peanut butter cookie bar with chocolate fudge frosting!
- The toppings are optional, but I like to add some sprinkles and nuts for decoration. Any color sprinkles you like will work, and chopped peanuts add some crunch.
- I think it’s easier to make the fudge on the stove, but you can use the microwave, too. If you use the microwave, you will need to melt the chocolate with the milk in one-minute increments stirring between each. It takes a while to do it this way, and be careful because the bowl gets very hot.
- Storing cookie bars: Once the bars are cooled, you can store them in an airtight container. They will keep well for up to three days at room temperature – if they last that long!
- Can you freeze cookie bars? Yes you can – these can be frozen with or without the fudge topping.
