Have you ever made a recipe that you just weren't sure about? Even while I was baking this, I didn't know if it would be good or not. I had the idea to change up the recipe for Tuxedo Bars and I had a strawberry cake mix in the pantry. Chocolate and strawberries go together, right? I asked about the cake on Facebook, just to see if others thought it sounded good. I also wanted to know what kind of icing to put on it. I couldn't decide between chocolate, vanilla or strawberry. After reading all the opinions or friends, I decided to go with strawberry icing. The result was marvelous! The fresh strawberry frosting really set off the cake and the mini chocolate chips gave it just enough chocolate flavor. This make a 15x10-inch sheet cake, so it's great for a crowd. But I think it would also freeze well, if you have more than you can eat.
