Why This Recipe Works

Lastly, the generous amount of chocolate chips provides bursts of rich chocolate flavor, complementing the cake beautifully.
Ingredients at a Glance
- 1 (15-ounce) box yellow cake mix
- 1/2 cup (113g) unsalted butter, softened
- 1 large egg
- 1 (14-ounce) can sweetened condensed milk
- 2 cups (340g) chocolate chips
Before You Start: Equipment
- Mixing bowl: For combining your ingredients.
- 9×13 inch baking pan: To bake the bars to perfection.
- Spatula: For spreading the batter evenly in the pan.

Chocolate Chip Gooey Cake Bars Made Stepwise

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your cake bars bake evenly.
Step 2: Prepare the Baking Pan
Grease a 9×13 inch baking pan with butter or line it with parchment paper for easy removal later.
Step 3: Mix the Base
In a large mixing bowl, combine the yellow cake mix, softened butter, and egg. Mix until well combined and the batter is smooth.
Step 4: Spread the Batter
Pour half of the batter into the prepared baking pan and spread it evenly across the bottom. This will serve as the base layer.
Step 5: Add the Chocolate Chips
Sprinkle 1 cup of chocolate chips evenly over the batter in the pan. This will create a deliciously melty, chocolatey filling.
Step 6: Prepare the Gooey Layer
In a separate bowl, pour the sweetened condensed milk and mix in the remaining batter until well combined. The mixture will be thick and gooey.
Step 7: Pour the Gooey Layer
Carefully pour the gooey mixture over the chocolate chips in the pan. Use a spatula to spread it gently to cover the chocolate chips as evenly as possible.
Step 8: Top with Remaining Chocolate Chips
Sprinkle the remaining 1 cup of chocolate chips on top of the gooey layer, ensuring they are evenly distributed.
Step 9: Bake
Place the pan in the preheated oven and bake for 25-30 minutes, or until the edges are golden brown and the center is set but still slightly gooey.
Step 10: Cool and Serve
Once baked, remove the pan from the oven and let it cool in the pan for about 10-15 minutes. Then, cut into squares and serve warm or at room temperature.
Holiday & Seasonal Touches

- For a festive touch, add a sprinkle of cinnamon to the batter.
- During the holidays, consider incorporating crushed peppermint candies or holiday-themed sprinkles.
- For a fall-inspired variation, swap out the chocolate chips for butterscotch or pumpkin spice chips.
- In the summer, fresh berries can be mixed into the batter for a fruity twist.
Troubleshooting Tips
- If your bars are too gooey in the center, bake them for a few extra minutes, checking for doneness.
- For firmer bars, allow them to cool completely before cutting.
- If you find the top is browning too quickly, cover the pan loosely with aluminum foil during baking.
- Ensure that your oven is properly calibrated for accurate baking times.
Storing, Freezing & Reheating
These Chocolate Chip Gooey Cake Bars can be stored in an airtight container at room temperature for up to 3 days. If you want to keep them longer, they can be frozen for up to 2 months. Wrap the bars tightly in plastic wrap and then place them in a freezer-safe bag. To reheat, simply thaw at room temperature or warm in the microwave for a few seconds until just heated through.
Your Questions, Answered
Can I use a different cake mix flavor?
Absolutely! While yellow cake mix is traditional, you can experiment with chocolate, vanilla, or even spice cake mixes for unique flavor variations.
What if I don’t have sweetened condensed milk?
If you don’t have sweetened condensed milk on hand, you can make a substitute using evaporated milk and sugar. For each cup of sweetened condensed milk, combine 1 cup of evaporated milk with 1 1/4 cups of sugar, heat until dissolved, and let cool.
Can I add nuts to the recipe?
Yes! Chopped nuts such as walnuts or pecans can be added for an extra crunch. Just fold them in with the chocolate chips for a delightful texture contrast.
How do I know when the cake bars are done baking?
The edges should be golden brown, and the center should be set but still slightly soft. A toothpick inserted into the center should come out with a few moist crumbs, indicating that they are perfectly gooey.
The Takeaway
These Chocolate Chip Gooey Cake Bars are a delightful treat that combines the best of cake and cookie worlds.
