One of the biggest problems with a stand mixer is that the mixer blade does not reach all the way down to the bottom of the bowl, so you have to get out a spatula and mix your batter by hand. It’s only an annoyance because the beauty of a stand mixer is that it should be hands-free. Over the past several months, a number of companies have come out with  mixer attachments that offer a solution to this problem, and Beater Blade is one of them.
Beater Blade looks like the regular paddle attachment for a mixer, but it has a flexible “wing” that reaches out from the paddle to the bottom of the bowl, so it scrapes the bowl with a soft blade that mixes efficiently without damaging your mixer. The company makes Beater Blades to fit all different styles and brands of electric mixers, including KitchenAid, Viking and DeLonghi, and all the Blades are dishwasher safe.
I used my Beater Blade to whip up some egg whites and to make a batch of cupcakes. It performed very well at both tasks, scraping in every last bit of flour for my cupcake batter - without over-mixing and making the cupcakes tough - and whipping the egg whites up so that they were fluffy and left no unwhipped pool of egg white around the dimple at the bottom of my KitchenAid bowl.  I was a bit skeptical before I tried it, but the Blade delivered all that it promised and is a nice accessory to have in the kitchen if you want to make better use of your stand mixer.
