Using Tequila in Buttercream

I have to admit that I was a little skeptical at first about how adding tequila to buttercream would go over. I didn't know if there would be enough tequila flavor to be noticeable...and for that matter, if it would be any good!

As it turns out, the tequila-lime combo works perfectly when combined with buttercream, and is just what our Margarita Cake needed!

Keep this simple recipe in mind for margarita cakes and cupcakes! We think that you'll love it!

How Much Tequila Should You Use in the Buttercream?

Although we only used three tablespoons of tequila in this generous batch of frosting, we found the flavor to be unmistakable without being overpowering.
However, if you like a stronger tequila flavor and are feeling adventurous, go for it! You can easily substitute out the milk in the recipe for more tequila (and then some). Enjoy!

  1. Hi Melisa Diamond. I would love to join you to learn how to bake cakes and decorate them. You are such an inspiration my dear. I have looked for a school where I can learn all these but I found your online cake school. I don't know how to pay for 1 year lessons as I am in Botswana in Africa. I don't have a credit card.

  2. Thank you! Was the perfect addition for a gin tonic drizzle cake recipe I found! I quartered the ingredients for my small cake and used only 200g sugar & a tiny bit more gin (instead of tequila) & lime juice. Very tasty ?
