I learned this recipe on the internet. There are many versions. The baking methods and directions are very similar to each other. But when I first baked it, I stumbled on a mistake that not many pointed out.

Eventually, I found that there are several do-it-and-forget-it tips that you and other bakers can use and make it more enjoyable for preparing this delicious cookie recipe.


Many recipes said that combine everything together in a baking dish and flatten the batter out and bake. Honestly, you will have quite a mess by doing it on a baking dish. Because the dish is very shallow, not to mention that the cake mix is everywhere on the kitchen counter. Even though it may be one more bowl to wash, a mixing bowl is a must to mix everything together before transferring the batter into the baking dish. Ultimately, washing an extra bowl will save you a lot of effort in cleaning the kitchen mess.

Mix chocolate chips into the dry ingredient first will make the pieces distribute more evenly throughout the batter.

Use a solid spoon made of wood or nylon will be easier to mix all ingredients once the melted butter is added in.

Many recipes you may find on the internet skip this step that I am going to share. When I first tried the recipe found on the internet, the bottom of the cake mix bar cookies was super crumbly. There are 2 easy ways to fix this. A greased baking dish works the best. Simply spray the bottom of the dish with non-stick cooking spray. Or line it with parchment paper, it works, too.

Vanilla extract is an optional ingredient. I added this in the second time when I made this recipe again. It turned out the fragrant and taste is very close to regular chocolate chip cookies.

You may be super anxious to dig into the yummy goodies as soon as it gets out of the oven. Let it sit for at least 10 minutes in room temperature first before cutting. The best tool to cut up the warm cookie bar is to use a plastic knife. It comes out very clean without having the chocolate sticking to it.

Cake Mix Bar Cookies Recipe and Directions

1 box (15.25oz / 432g) Yellow Cake Mix
1 stick or 1/2 cup (4oz / 101g) Butter (melted)
2 Large Eggs (beaten)
2 cup or (12oz / 340g) Chocolate Chips (I use semi-sweet chocolate chips)
1 tsp Vanilla Extract (optional)
No-stick Cooking Spray


  1. Preheat oven at 350F (177C).
  2. Melt butter in a small sauce pan at medium low to low heat.
  3. Whisk eggs in a separate bowl and then slowly whisk in melted butter and vanilla extract.
  4. In another bowl, add ingredients in this order: cake mix and chocolate chips (quick stir before adding the rest), lastly, butter and egg mixture. (Once dry and wet ingredients are combined together, you will need a utensil more sturdy to help mixing everything together. It is the perfect time to switch from the whisk to solid spoon.)
  5. Coat 9"x13” (23x33cm) pan with cooking spray and transfer cookie batter into the pan, use the same spoon flattening out the batter in even layer and bake for 20 minutes.
  6. Let it cool in room temperature for at least 10 minutes before cutting it and enjoy.
  7. When it is completely cooled down, store cookie bars in glass air tight container. They will be good up to 2 weeks.
