As the bars bake, the butter softens the cake mix into a rich, chewy dough. They come out of the oven golden and loaded with melted chocolate chips. Try them while they’re still warm, with a cold glass of milk.
Tips for Success
- Use yellow cake mix for a classic flavor, but white cake mix works if that’s what you have handy.
- Let the bars cool for at least 10 minutes before cutting to prevent crumbling.
- Store at room temperature for up to 5 days or freeze for up to 3 months.
- For extra texture (and who couldn’t use more chocolate), sprinkle a few chocolate chips on top just before baking.
