Ingredients
- 15 ounce box of yellow cake mix
- 2 eggs (beaten)
- 1/3 cup olive oil (or vegetable oil)
- 12 oz chocolate chips
Instructions
- Step 1: Preheat the oven to 350 degrees Fahrenheit.
- Step 2: Beat the eggs in a small bowl until smooth.
- Step 3: Add the cake mix and olive oil to the beaten eggs and mix well to form a thick batter.
- Step 4: Stir in the chocolate chips until evenly distributed; the batter will be very thick.
- Step 5: Grease a 9 x 13 inch baking dish to prevent sticking.
- Step 6: Spread the batter evenly in the prepared baking dish. This can take a few minutes as the batter is thick and sticky.
- Step 7: Bake for 20 to 25 minutes, or until a toothpick inserted in the center comes out clean.
- Step 8: Allow the bars to cool completely before cutting into squares. Store leftovers in an airtight container.
Tips & Variations
- Try substituting the olive oil with melted butter for a richer flavor.
- Add chopped nuts or dried fruit to the batter for extra texture and taste.
- If you prefer a gooier center, reduce the baking time by a few minutes.
- Use different types of chocolate chips, such as white or peanut butter chips, for a unique twist.
Storage

FAQs
Can I use a different type of cake mix?
Yes, you can use other flavors like chocolate or spice cake mix, but it will alter the flavor of the cookie bars.
Why is the batter so thick?
The batter is thick because it doesn’t contain much liquid beyond eggs and oil, which makes it sticky and dense—perfect for bars rather than drop cookies.
