I finally got around to using these Wilton's Bake Even Strips. I've had them for... probably almost a year! This week's Tuesdays with Dorie recipe, a layered carrot cake, was the perfect time to test them out.
I have the small package, which is two strips, enough for two 8 or 9 inch round pans. The strips are soaked in cold water, and excess water is squeezed out using your fingers. On my 9 inch pans, the ends just barely cross over each other, and are secured with a pin. They came out of the oven dry (and a warm to the touch), so I just let them cool and then stowed them away.
Results: I think my carrot cake layers came out great! I certainly don't feel the need to level them off. Some edges were slightly more browned than I'd like, but that may have to do with me not turning the oven down 25 degrees for my dark, nonstick pans. Overall I think they work great!
