In making the kids breakfast each morning, which has moved on from crepes and waffles to pancakes, I want a consistent amount of baking powder. I realized that the container has a built-in "measuring spoon". If you shake it with the lid on, powder gets up above the leveling shelf:

Take the lid off, and it remains:

Then you can dump it in the batter:

It's a bit awkward to do this with a full container, since you can't tip it very much, but it's quite easy once you've used a bit first.

With the particular brand of baking powder we've been buying it's consistently 2/3 of a teaspoon.

I wonder whether anyone has tried designing a baking powder container to make this easier? The current shape is not ideal for measuring, and it would make much more sense for it to be one teaspoon instead of 2/3.
