Margarita Cake with Key Lime Cream Cheese Frosting

This margarita cake recipe is made easy with a cake mix and frozen margarita mix. Look at the label on your margarita mix. If it says “ready to drink” it will have alcohol in it, which will cook out in the baking process.

Otherwise, the mix may only have orange liqueur, lime juice, sugar, salt and maybe some extra citric acid. 

It’s sweet, but not too sweet. Great for citric fans.

Great to serve at parties and banquets. 

It’s an easy-to-make dessert. Find the recipe card below!

Why add cream cheese to frosting?

Why not? Cream cheese is smooth, creamy and sweet and tart. It’s the perfect accompaniment to a cake flavored with lime juice. 

How do I substitute cream cheese frosting?

You can use Neufchatel for 33% less fat. Mascarpone has even more fat than cream cheese, but some people like the velvety texture. 

Can I use Greek yogurt instead of cream cheese?

It is a healthier alternative. It’s low in fat, high in protein, calcium, and vitamin B12.

How to serve Margarita Cake with Key Lime Cream Cheese Frosting?

This dessert can be cut up and served to guests by itself as a dessert or a snack. Fresh lime slices and lime zest are suggested as garnishes, but if you’re feeling a bit artistic, you can decorate with curlicues of green icing. 

Cooking Tips:

As this recipe calls for egg whites, you will have to separate the eggs. You can do this with your hand or the shells, but the easiest way is with an egg separator. If you do not have one, an empty water bottle can be used to suction the yolk out of the white. As with any cake, do not overmix.

Variations:

Lemons can be used instead of limes. Daiquiri mix can be used instead of margarita mix.
