Peanut Butter Chocolate Chip Bars

I’ve been making these delicious and easy peanut butter cookie bars with cake mix and chocolate chips for several years now and it’s one of my favorite treats to make for my family.

I love it because it uses everyday ingredients that I almost always have in my pantry and fridge.

These peanut butter chocolate chip bars are also super quick to whip together in a 9×13 pan, making them the perfect choice for taking to family gatherings and parties.

And trust me when I say they’re SO good – it’s pretty much a given that you won’t come home with any leftover dessert bars.

Not to mention the combination of peanut butter and chocolate are pretty much THE BEST ever, am I right?!

What’s in Peanut Butter Chocolate Bars?

These cake mix bars come together with just 7 simple ingredients which I’ve included below.

• Boxed Yellow Cake Mix
• Creamy Peanut Butter
• 1 Large Egg
• Cream Cheese (You can use full fat or 1/3 fat)
• Milk (I prefer 2%)
• Granulated Sugar
• Semi-Sweet Chocolate Chips

You only need just a few simple kitchen tools to make these peanut butter bars.

• 9×13 Cake Pan
• Electric Hand Mixer
• Glass Mixing Bowl
• Rubber Spatula
• Measuring Cups
• Measuring Spoons
• Cooling Rack

Tips for Making Peanut Butter Chocolate Chip Bars

Use a metal or glass pan to bake them 

I recommend using a metal 9×13 cake pan for baking these peanut butter and chocolate chip bars.

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.

You can, however, use no stir varieties such as this natural one from JIF.

That said – if you try other types with success, please let us know in the comments!

Can I Use Another Nut Butter?

Again, I wouldn’t recommend this recipe with any nut butters that require stirring/refrigeration, but you should be fine with a no-stir variety.

I’d recommend a no-stir almond butter, cookie butter, or even hazelnut (Nutella) would make for a delicious swap.

Can I add Nuts?

Yes! These bars are delicious with some peanuts added on top.

Simply add 1/4 cup peanuts right on top with the chocolate chips.

It adds a delicious crunch and the perfect sweet and salty balance.

You could also try adding walnuts or pecans if you prefer that instead.

Should Peanut Butter Chocolate Chip Bars be Refrigerated?

Yes, because these dessert bars feature a cream cheese filling, they should be refrigerated to maintain 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.

Can these cake mix bars be frozen?

Yes. You can freeze them in a freezer safe bag or container for up to 3 months.

Once ready to eat, thaw in the fridge overnight or reheat individual servings in the microwave until warm.

Step 1 – Preheat & Spray Your Pan

Preheat the oven and spray a 9×13 metal pan or glass baking dish with non-stick cooking spray.

Prepare your crust by combining the yellow cake mix, 2/3 of the peanut butter, and egg in a large mixing bowl and mixing together with an electric hand mixer until crumbly.

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.

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.

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.
