I was really rushed when making these fresh strawberry Hello Kitty birthday cupcakes for my friend's daughter's birthday. As a result, I not only messed up on the cupcake batter (that's a whole other story), I also messed up on the frosting.
While making the cream cheese frosting, I had decided to add some pureed strawberries... bad decision. I normally make my fresh strawberry buttercream using strawberry puree, and the frosting comes out great because my buttercream always needs a bit of liquid to buttercream anyway (usually milk or water). But I had forgotten that cream cheese frosting is already a very loose frosting, and when I added the strawberry puree it became very goopy. And un-pipeable. I tried adding small pieces of cold butter, thinking it would make it thicker. But it only made it really lumpy. So I had to start over with a new batch of cream cheese frosting!
After I was finally done decorating the cupcakes, I still had a batch of goopy, runny, lumpy strawberry cream cheese frosting, unused and sitting in my fridge. I didn't want to throw it out - what could I turn this into? And then I remembered a recipe for Japanese-style cheesecake that I've been meaning to try out. I quickly checked the recipe - it called for cream cheese. Check. It also called for sugar and butter. Check, and check - all of those were already in the frosting. All I needed to add was flour, cornstarch, salt, and eggs!
So I ended up turning my runny frosting into a fresh strawberry Japanese-style cheesecake. I used this recipe - It requires one-fourth of the cream cheese required in NY-style cheesecake, and the batter is lightened with whipped egg whites. After I baked it in a water bath and then let it cool, I couldn't wait - I had to try it. The cake turned out light, fluffy, and lived up to its nickname of "cotton cake". I usually see this cake decorated with fresh fruit and glaze, but I actually thought it tasted great just plain. The next time I make it, hopefully I'll have the will power to refrain from cutting into it before it's decorated!
