Frequently Asked Questions
Can I use regular cocoa powder instead of dutch-processed?
Yes. Dutch-processed cocoa provides a deeper chocolate flavor, but regular cocoa powder will work just fine.
Do I have to broil the marshmallows?
The broiler creates the classic toasted smores flavor and appearance, so it’s highly recommended.
Why let the brownies cool briefly before adding the marshmallows?
A short cooling period helps to avoid the marshmallows sinking into the brownies.
