Key Lime Cupcakes

It’s Key Lime Cupcakes for you all today.  They begin with a good old cake mix.  Then they get an additional color and flavor from a package of lime gelatin.  Next the flavor and color gets an added bonus of key lime juice. A few drops of food coloring are added too.  

The cupcake itself has a larger crumb than most cakes. I believe this is due to the addition of the gelatin. They are almost more like a muffin consistency in texture.  They also end up with a flat top rather than a round top. You may find that they even sink a little in the center, but don’t be alarmed.

After the key lime cupcakes cool, they get an extra punch of lime from a lime glaze.  Finally, they get a finishing off with a sweet cream cheese frosting to balance out the flavors.  I shared these with a few friends who all enjoyed them.  My husband even enjoyed them and he isn’t a fan of key limes at all!

    I just made these tonight for an Easter party at work. Put little jelly beans on top for garnish. My husband and I had to try one and these are fantastic!!! The Lime glaze is so tart and adds an extra zing other cupcakes dont have. If you like Key Lime, you’ll love these cupcakes.

    I love this recipe! I did not have key lime juice and I used some orange mango juice instead. Very moist and always requested!
