I am always paranoid about trying new recipes, mostly because I never know how they will rise during the baking process. I filled 3/5 full, as I do most recipes, but this one could have used a tablespoon more of batter since they did not rise much. I made a lemon cake with a light lemon-vanilla cream filling, topped with a lemon buttercream. I whipped the hell out of the butter today and it came out perfectly fluffy!
I topped with my favorite white sprinkles and yellow sugar, yay! I'm getting better with a piping bag, I swear :P
