I came across this recipe at a blog called Lil' Luna and I immediately knew I needed to give this cake a try. Good thinking on my part, this cake is not only easy, but absolutely delicious!!!
You may find the recipe on her blog (along with a lot of other sheet cake recipes) by clicking HERE, or find the recipe below.
1 box white cake mix (plus ingredients required for mix)
juice of one lime
1 (3oz pkg) lime flavored instant JELLO gelatin box
1/4 c butter, softened
4oz cream cheese, softened
2 c powdered sugar
1 tsp vanilla
1 tbsp (or more) lime juice
a few tsp lime zest
In a bowl, pour cake mix and JELLO powder. Add the ingredients required for the cake mix as specified on the box (water, oil and eggs), as well as the lime juice. Mix until all the ingredients are well mixed and you have a smooth cake batter (1-2 minutes). Pour your cake batter evenly on a well greased half sheet/jelly roll pan (18" x 13"). Bake at 350 degrees Fahrenheit for 20-22 minutes. Let cool.
While your cake is cooling make the frosting. Start by mixing the softened butter and cream cheese. Add the vanilla, lime juice, and lime zest. Finish off by adding the powdered sugar. If your frosting ends up being too thick, you may add one to two tablespoons of milk to thin it out. You may also add more lime juice if you'd like. I made mine without the milk and extra lime, and found it to be just perfect.
Frost your cake and sprinkle some more lime zest on the top to decorate. Enjoy!
