Try my soft, delicious, and gooey peanut butter chocolate chip bars for a quick and easy dessert! These cake mix cookie bars are made in a 13×9 pan using a yellow cake mix, creamy peanut butter, cream cheese, and are topped with semi-sweet chocolate chips.
Easy Peanut Butter Chocolate Chip Bars
Today I’m excited to share one of my favorite cake mix dessert bars – Peanut Butter Chocolate Chip Bars.
These delicious peanut butter and chocolate chip bars are one of my favorite 9×13 desserts to make for a gathering, and they’re a super easy dessert that starts with a box yellow cake mix and other simple ingredients.
Even better, these easy peanut butter bars take less than 30 minutes to bake, making for an easy weeknight or weekend treat.
Alternatively, if you don’t have a metal pan, you can use a glass 9×13 baking pan, but make sure you check it at the lowest recommended baking time to ensure you don’t overbake your bars.
Metal tends to cook baked goods more evenly, which is why I prefer using it.
Let the bars cool before cutting them
I know it’s tempting to want to dig in right away, but because these are a more gooey dessert bar (and loaded with chocolate chips on top), you’ll want to let the dessert bars cool on a wire cooling rack before cutting them.
I recommend waiting at least 30 minutes – 1 hour before cutting them with a plastic knife.
Tip: If you’re not in a hurry or are making them in advance, you can even wait to cut them after putting them in the fridge for a bit to firm up.
Store leftover bars in the fridge
Because these dessert bars are made with cream cheese, it’s best to refrigerate them to maintain optimal freshness.
Once they’ve cooled completely and you have cut them into bars, store in the fridge in an airtight container for up to 5 days.
If desired, you can reheat the bars in the microwave for 15-30 seconds before eating, but they’re also delicious cold.

Peanut Butter Chocolate Chip Bars FAQ’s
Can I Use Another Kind of Chocolate Chips?
Sure! Use whatever kind is your favorite.
I personally love the balance that semi-sweet chocolate chips gives these cake mix peanut butter bars, but you can also use milk chocolate chips, dark chocolate chips, white chocolate chips, or a combination.
Can I Use a Natural Peanut Butter?
I wouldn’t recommend using a natural peanut butter that has to be stirred/refrigerated since those tend to be oily and it might alter the texture.
Use your hands or a fork to press the crumb mixture into the greased baking pan, ensuring it gets evenly in all the corners of the pan.
Step 3 – Prepare Your Cake Mix Bars
In the same large mixing bowl as before, beat together the softened cream cheese and 1/3 cup of peanut butter with an electric hand mixer until combined. Next add in sugar and milk and mix together until smooth.
Carefully pour the mixture over the crust. Spread evenly and sprinkle with chocolate chips.
Step 4 – Bake
Bake the peanut butter and chocolate chip bars in the oven for 25-30 minutes or until the edges are lightly browned and the center is set.
Step 5 – Cool and Cut
Let the peanut butter chocolate chip bars cool completely on a wire cooling rack before cutting with a plastic knife.
Serve and enjoy!
