Peanut Butter Chocolate Chip Bars with Yellow Cake Mix
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.

Step-by-Step Directions
Step 1 | Combine the Ingredients
- 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.
Step 2 | 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.

Could these be made in a 9x9 pan?
Lois says
Yes, you can make this recipe in a 9x9-inch pan. However, since the original recipe is designed for a 9x13-inch pan, using a smaller pan will result in thicker bars. To ensure they bake evenly, you'll need to adjust the baking time accordingly.
Typically, thicker bars may require a longer baking time. It's advisable to start checking for doneness around the original bake time of 15 to 17 minutes, but be prepared to extend the baking time by an additional 5 to 10 minutes. Keep an eye on the bars and use a toothpick to test the center; if it comes out clean or with a few moist crumbs, they're done.
Remember, baking times can vary based on oven differences and the exact thickness of the batter, so it's best to monitor closely to avoid overbaking.
