A rubber spatula is your best tool to get every bit of cake batter into the pan (leaving just a little bit behind in the bowl to lick). It also folds beaten egg whites into a batter. A plastic bowl scraper can be used, of course, to scrape out bowls, but we use it to scoop the measured dry ingredients into the mixing bowl. A metal bench scraper is best for dividing bread doughs and for scraping your work surface clean.
