FAQ
1. Can I use yellow cake mix instead of white cake mix?
Yes. Yellow cake mix works well and will give the blondies a slightly richer flavor.
2. Can I add other mix-ins?
Absolutely. Try adding chocolate chips, macadamia nuts, coconut flakes, or colorful sprinkles.
3. Why is my batter so thick?
Blondie batter is naturally thick. This helps create the chewy cookie-bar texture.
4. How do I know when the blondies are done baking?
The edges should look set and lightly golden while the center remains slightly soft.
5. How should I cut blondies cleanly?
Let them cool completely, then use a sharp knife and wipe the blade between cuts for neat slices.
