How to Make Chocolate Chip Cookie Bars From Cake Mix
Step 1: Preheat the Oven
Preheat your oven to 350°F.
Grease a 9×13-inch baking pan or line it with parchment paper for easier cleanup.
Step 2: Mix the Dough
In a large mixing bowl, combine:
- cake mix
- melted butter
- eggs
- vanilla extract
Mix until a thick dough forms.
Fold in the chocolate chips.
The dough will be much thicker than regular cake batter.
Step 3: Spread Into the Pan
Press the dough evenly into the prepared baking pan.
Use a spatula or lightly greased hands to smooth the top.
Sprinkle extra chocolate chips on top if desired.
Step 4: Bake
Bake for 20–25 minutes.
The edges should look lightly golden while the center remains slightly soft.
Do not overbake.
The bars will continue setting as they cool.
Step 5: Cool and Slice
Allow the cookie bars to cool completely before slicing.
Cut into squares or rectangles and serve.
Tips for the Best Cookie Bars
Don’t Overbake
Slightly underbaking creates soft, gooey centers.
Use Room Temperature Eggs
This helps the dough mix more evenly.
Add Extra Chocolate Chips on Top
This gives the bars a bakery-style appearance.
Line the Pan With Parchment Paper
Makes removing and slicing the bars much easier.
Let Them Cool Before Cutting
Warm bars can fall apart if sliced too early.
