Prepare cake batter as directed and swirl in some sprinkles.
Put 1 cup of batter on a Belgian Waffle iron and cook on med/high for 2 minutes.
Sprinkle with additional sprinkles if desired.
Here's what I used. I only had 1/2 package of the cake mix and it made 3 waffles so I am assuming the whole package would make 6.
I used the large scoop by pampered chef and scooped the batter in the center of the triangles. Any 1/4 cup scoop will work. This method worked great.
