Key Lime Cupcakes
For step-by-step instructions, check out the printable recipe card below. But here is what you’ll need to get started!
- LEMON CAKE MIX – Lemon cake mix can be hard to find. If you can’t find it, you can substitute for another cake mix. White, yellow or vanilla could work. We’ve also used Lemon Pound Cake Mix in a pinch. The cupcakes were still delicious, they just came out a little denser.
- LIME GELATIN – One small, 3 ounce box.
- WATER –
- VEGETABLE OIL – We love baking cupcakes with vegetable oil as it really helps keep the results super moist!
- KEY LIMES – In total, you’ll need about 2/3 cups of key lime juice, so make sure you buy enough, depending on the size and look of them in your grocery store. If you can’t find key limes, you can order the juice online. Or, you can also just use regular limes.
- 3 LARGE EGGS – Make sure you get your eggs to room temperature for best results.
- GREEN FOOD COLORING – If desired to give your cupcakes a green tint.
- POWDERED SUGAR – Also called Confectioners Sugar.
- LIME JUICE –
- CREAM CHEESE – One 8 oz package. Make sure you soften it or it will be really hard to work with.
- BUTTER – Make sure you soften your butter too. You can use salted butter or unsalted butter.
KEY LIME JUICE –
- POWDERED SUGAR –
- LIME PEEL – Use a grater to use key lime zest as a garnish if desired. We recommend zesting your limes BEFORE you juice them.
Do You Need Salt In This Recipe?
Some Key Lime Cupcake Recipes do add salt. This is usually because they use Key Lime Extract, and the salt helps balance that out. Because we aren’t using Key Lime Extract, our cupcakes aren’t quite as “potent” as some of the other recipes. We are going for a gentle, more subtle Key Lime Flavor. But if you want to add a little salt to balance that out, go for it. You could also just use salted butter.
Storage, Freezing Key Lime Cupcakes
Store leftovers in your refrigerator in an Airtight Container. They should be good in your fridge for about 5 days.
I would not freeze these cupcakes, as the cream cheese frosting may separate a bit when defrosted.
