Easy cake mix fudge bars are rich, gooey, chocolaty, and delicious. Some people call them “can’t leave alone bars,” and it is for good reason, you will want to keep going back for more.
If you like chocolate, peanut butter, and soft cake like cookie bars, you are in the right place. These easy bars combine all of those things with some condensed milk to make a tasty fudgy treat.
These yummy fudge bars only take 7 ingredients. If you have a well stocked kitchen, you may already have them on hand.
I don’t know about you, but I tend to stock up on things like cake mixes, chocolate chips, and condensed milk when they are on sale at the grocery store. They all have a nice long shelf life, and I find it very convenient to have them on hand.
That way, when you want to make something delicious, you are likely to have the ingredients to make something fun. These fudge bars are a perfect example of a quick and economical treat you can have ready to go in the oven in just a few minutes.
Turning a Cake Mix into Delicious Bars
Having a cake mix or two in the pantry means you are just a few minutes away from baking up something delicious. There are so many fun ways you can turn a box of cake mix into something other than a cake.
Of course, they are great for making easy cakes as well. Then, all you have to do is make a delicious homemade frosting to turn it into a special treat.
This particular recipe starts with making a cookie/cake hybrid using the cake mix, oil, and eggs. Pat about 2/3 of the mixture onto the bottom of a greased 9×13-inch pan to form the bottom crust.
It won’t be a very thick layer, but it should be enough to cover the whole thing. Then it is time to turn your attention to the fudgy layer.
Luckily, this tasty layer is just as easy to put together as the crust. If your butter is cold, go ahead and start melting it in a medium glass bowl in the microwave.
Once the butter is most of the way melted, add peanut butter chips and chocolate chips along with a can of sweetened condensed milk. Cook the mixture in short 20-30 second bursts in the microwave until you can stir it smooth.
Chocolate scorches easily, so it is better to take it out and stir it frequently than to accidently burn it. Now pour this fudge mixture over the bottom crust.
Drop little bits of the remaining cake mix mixture over the top of the fudge. It won’t be enough to cover the fudge layer, so just try to distribute it relatively evenly.
Bake the bars for 25-30 minutes. The cake parts should be golden brown and look cooked.
These bars are really gooey when hot, so I would recommend cooling them completely or even chilling them a bit before cutting them. That will make getting nice-looking pieces easier.
That is it! These bars are rich and fudgy.
They have a nice mix of peanut butter, chocolate, and vanilla. It really doesn’t get much better!
Substitutions and Adaptations
Of course, you can play with the chips you use in the fudge layer. Use all chocolate chips if you don’t want the peanut butter.
We used milk chocolate because they are Little Dude’s favorite. However, using semi-sweet chocolate chips would help to cut the sweetness of the condensed milk.
If you really like peanut butter, you can stir some in with the cake mix mixture. I have seen people use as much as a cup of peanut butter in the crust.
For big chocolate fans, you could use a chocolate cake mix instead of yellow. Or experiment with different flavor combinations of chips and cake mixes to match your preferences.
