Had some key lime juice to use up and this worked well. We froze several and they are good that way also.

This recipe was fast and super easy. I did have to make a few changes because of what I had on hand. I used bottled lime juice and since no fresh limes I didn't have any zest. So I added extra lemon extract in the crust. This turned out tangy and sweet, but not overly, which IMO lots of citrus baked goods are. I enjoyed the lower fat content because lemon/lime squares can be extremely high in fat. The only thing I didn't like was the streusel topping. It just crumbled off and made a mess all over the counter and floor. Even though, I will make this again making sure to try with the fresh juice and zest. Thank you for a tasty recipe. My daughter (6) and I had a wonderful time making this together.

I just made this from my old copy of Cooking Light and had to check here because I definately want to add it to my 'zaar cookbook. This is very good, even though we did not use key limes. Big thanks for clearly separating the ingredients and steps; your writing is more clear than Cooking Light.
