Any Belgian waffle recipe should work with a boxed mix.  Just make sure that your boxed mix is compatible with your waffle iron.  If you use a different recipe and mix, the result will be slightly different.

From scratch, if you have time.

What is the difference between Belgian waffles and American waffles?

Belgian waffles are a type of pancake.  Usually they’re thick, covered in syrup, and topped with fruit or powdered sugar.  They’re not covered with a batter and are cooked on a flat surface, usually a griddle.

I want to make Belgian waffles. Should I make Belgian waffles from scratch or boxed mix?
