Key Lime Cupcakes Recipe

We’ve been spending more time baking in the kitchen together, and I have to admit that it’s a blast. The boys love helping out and knowing that what they’re eating, they’re a part of!

The fun part about baking cupcakes is that they’re so simple to flavor. Adding the lime flavoring to the cupcakes creates a fun and tasty surprise!

Combining the cupcakes with homemade frosting proves it doesn’t have to be difficult. Just a few easy ingredients are needed to create these tasty treats.

Does lime juice and lemon juice taste the same?

Regarding citrus fruits, lime and lemon are two of the most popular. While they may look similar on the outside, many people debate whether or not they taste the same.

Some argue that lime juice is sweeter and less acidic, while others claim that lemon juice has a more tart flavor.

Ultimately, the taste difference between lime juice and lemon juice may be subtle, but it’s there.

For those who love to cook or experiment with different flavors, experimenting with both types of juice is a fun way to explore new tastes and add some variety to your dishes.

Can I add frosting to warm cupcakes?

The tantalizing aroma of freshly baked cupcakes fills your kitchen, and you eagerly count the minutes until they are ready to be frosted. But wait!

You’ve heard that adding frosting to warm cupcakes can cause a creamy disaster. Fear not; if you follow a few simple steps, you can have your cake and frost it too.

First, ensure your cupcakes have cooled to at least room temperature before applying frosting.

Next, apply a bit and see if it holds steady on the cupcake. If it does, you’re good to go to frost the rest!

This Key Lime Cupcakes Recipe is an easy dessert loaded with citrus flavor. Fun and simple summer treat!


  • 1 ⅔ cups of sugar
  • ½ cup of unsalted butter, softened
  • 6 large egg whites
  • 2 cups of all purpose flour
  • 2 ½ tsp Baking powder
  • ½ tsp Salt
  • 1 ¼ cup of cold milk
  • ¼ cup of vegetable oil
  • 1 tsp key lime zest
  • 1 Tbsp key lime juice

Key Lime Frosting Ingredients:

  • ½ cup of unsalted butter, softened
  • ½ cup of shortening
  • ½ t.sp alt
  • 1 tsp Key lime zest
  • 2 Tbsp Key lime juice
  • 4 cups of powdered sugar
  • 1 sleeve graham crackers, crushed
  • Additional key limes for decoration, sliced


  1. Preheat the oven to 350 degrees. Line a cupcake pan with cupcake liners.
  2. Beat the butter in a mixing bowl until fluffy. Add the egg whites, milk, key lime juice and zest, and oil. Mix well.
  3. Combine the flour, sugar, baking powder, and salt in a different bowl. Whisk.
  4. Add the dry ingredients to the wet ingredients and mix on low for 1 minute. Scrape the side of the bowl and mix on medium speed for another minute.
  5. Add the cupcake batter to the liners, 2/3 full.
  6. Put the pan in the oven and bake for 14-16 minutes.
  7. Let the cupcakes cool before adding frosting.
  8. To make the frosting, mix the butter and shortening. Add the key lime juice, zest, salt, and half the powdered sugar. Mix on low until most of the sugar is incorporated. Scrape the sides of the bowl and then add the rest of the powdered sugar.
  9. Mix on medium speed for one minute. If you need to add more lime juice to thin out the frosting, you can.
  10. Add the frosting to the pastry bag that has a large round tip on the end.
  11. Once the cupcakes are cooled, pipe the frosting on top starting at the outer edge.
  12. Add the crushed graham crackers by putting the crumbs on a plate and then carefully following the edges of the frosted cupcakes to coat them.
  13. Slice the limes and add one in the middle of the frosting.
