What You’ll Need
Key Ingredients

- ½ Cup Milk – I typically use 2% but feel free to swap for any milk or plant-based alternative.
- ⅓ Cup Vegetable Oil or Canola Oil – This helps keep the bars fluffy and light.
- 1 Cup Chocolate Chips – Because who can resist more chocolate?
Optional Add-Ons
If you want to elevate your bars even further, consider adding nuts, dried fruits, or even a sprinkle of sea salt on top for an extra flavor boost.

Step 2 – Mix It Up
In a large bowl, combine the cake mix, egg, milk, and oil. Stir until just incorporated—don’t overmix or your bars won’t be as tender! Fold in those chocolate chips.
Step 3 – Bake It Perfect

Spread the batter evenly into your prepared pan. Bake for 20-25 minutes, or until a toothpick comes out clean.
Pro Tip – Keep It Crispy, Not Greasy
Allow the bars to cool completely before cutting. This ensures they won’t fall apart and will keep their delicious chewy texture.

Can I use a different flavor of cake mix?
Yes, absolutely!
You can swap the yellow cake mix with chocolate, funfetti, or even red velvet for a fun twist.
Different cake mix flavors let you personalize the bars to your taste or the season. Chocolate cake mix adds richness, while funfetti brings color and a party vibe. Just keep the base ratio of wet to dry ingredients the same.
How do I know when the bars are done baking?
They’re done when a toothpick inserted in the center comes out clean.
You should also notice the edges turning golden and slightly pulling away from the sides of the pan.
Don’t overbake—remember, they’ll continue to cook slightly as they cool. Aim for that perfect soft, chewy center!
