Peanut Butter Chocolate Chip Bars

Peanut Butter Chocolate Chip Bars are full of chocolate chips and delicious creamy peanut butter. Using a cake mix to bake cookies is just another one of my favorite Cake Mix Hacks that I love to share with you! Let me show you how easy these are to make.

Everybody needs easy cookie bar recipes with few ingredients in their recipe box and this recipe for Peanut Butter Chocolate Chip Bars is just that…easy!

They’re the perfect dessert to make for your family when you need something sweet.

You never know when you need to make a dessert recipe at the last minute. When my son was in high school, I had to make a lot of desserts for football team dinners, not to mention the snack bar on game night. 

Sometimes I didn’t get much notice for when a dessert was needed, which is why I love using a cake mix to create this recipe for Peanut Butter Chocolate Chip Bars.  They’re ready fast and everyone loves them.

What you’re really doing is creating a cake mix hack by adding a few extra ingredients to a boxed cake mix. The end result is a totally different recipe than what’s featured on the front of the box.

Ingredients for Bar Cookies.

Directions

I find it easier to use a hand-held mixer to combine all the ingredients together, but you can definitely do this by hand with just a wooden spoon. Once the ingredients are combined, add them to the bottom of a 9X13 baking dish that’s been sprayed with non-stick cooking spray. 

Use your fingers or the back of a spoon to help smooth out the cookie dough into the greased pan.

Baking Instructions

Bake in a preheated 350 degree oven for 15 to 17 minutes or until the bars are golden brown.

Tip: After the cookies have cooled, place a cutting board on top of the baking dish and then invert to flip the baked bars out! I find them much easier to cut on top of a cutting board than in the baking dish.

Peanut Butter Chocolate Chip Bars

Peanut Butter Chocolate Chip Bars

Yield: 18 - 24 bars
Prep Time: 10 minutes
Cook Time: 15 minutes
Total Time: 25 minutes

Ingredients

  • 1 box yellow cake mix
  • 2 eggs
  • 1/3 cup creamy peanut butter
  • 1 cup chocolate chips
  • 1/3 cup oil

Instructions

  1. Combine all the above ingredients into the bowl of a stand-up mixer and combine well. You can also combine all the ingredients using a wooden spoon.
  2. Press out the mixture into a 9X13 baking dish that's been sprayed with non-stick cooking spray.
  3. You will have to use your fingers or the back of a spoon to spread everything out evenly as the dough will be sticky.
  4. Bake in a 350 degree oven for 15 to 17 minutes or until the bars are golden brown.
  5. Let cool slightly before removing them from the baking dish to slice into bars.

Notes

Easy Tip:

I find it easier to slice by removing them from the baking dish to slice into bars on top of a cutting board.

      I’m not sure how that would work Mary! I’ve only used cake mixes for this recipe, not a cookie mix. Thank you for visiting.

          Hi Paula, I sent you a personal email as well. You don’t say that you added the peanut butter? That could be the problem. Let me know!

    Looks yummy! And I love a 'pan cookie' or bar like that because it doesn't involve all the shaping that cookies take.
