Chocolate Cake with Key Lime Cream Cheese Filling

Chocolate cake with Key lime cream cheese fillingWhen I received this interesting Fillables pan to try and review I was intrigued. The pictures on the box look so pretty and the possibilities are infinite! I really had trouble deciding what to make. Rummaging through my pantry and freezer, plus looking for inspiration online I decided to recreate one of my favorite flavor combinations chocolate and Key lime. When I told a friend about the flavors she was skeptical and asked if I’d ever had it. I have because Godiva makes a dark chocolate Key lime truffle, that if you’ve never had it, will rock your world! Of course, you have to like Key lime.

I had 2 cake mixes and frozen real Key lime juice on hand so I thought I’d give it a try. I set off to find a filling recipe and wound up at the Taste of Home website. The original recipe was for Key lime mousse cups but I decided to use it as the filling. Well, it was a complete success. I took it to a meeting at school and there was not a morsel left. Many of my “taste testers” commented that the filling wasn’t too sweet, which they liked. So, with it also being Taste of Home Tuesday, be sure to check out the other links below for more great recipes.

There really isn’t anything I don’t like about this Fillables pan. It’s easy to store, easy to use, makes an impressive cake, and has limitless flavor combination possibilities. Plus, if you cut it between the dips in the pan, you get a good size portion with the filling in the middle. Some ideas are yellow cake with chocolate frosting, chocolate cake with buttercream, any flavor with fruit, or any type of candy such as chocolate chips, M&M’s, or even, jelly beans as a fun surprise for Easter. There are a variety of shapes available including cupcake cones, 9 x 13-inch rectangle pans, 10-inch round, and a few others. Fun for graduation, special occasions, birthdays, family, friends, or church potluck parties.

  1. I honestly wouldn’t have thought chocolate and lime could be a thing, but I’m willing to trust you because this looks amazing! My gut would have said a vanilla cake, but I’ve gotta give chocolate+lime a chance!
