These tangy margarita cupcakes turn your favorite drink into a tasty dessert that's perfect for grown-up parties. The cupcakes have real tequila in them and come topped with a zingy lime frosting, giving you all the flavors of a summer cocktail in a fun, bite-sized treat.
I whipped these up for the first time when my sister turned 30 and we couldn't visit our go-to Mexican spot. Everyone at the party was so blown away by these boozy treats that they've now become what I'm known for at summer get-togethers and Cinco de Mayo celebrations.

Delicious Margarita Cupcakes Steps
- Heat Your Oven:
- Get your oven hot at 350°F for even cooking. Put paper liners in your muffin tin so the cakes won't stick and cleanup's a breeze.
- Make Tangy Milk:
- Mix your room temp milk with fresh lime juice and let it sit for around 5 minutes. This makes a tangy milk that adds moisture and boosts the lime taste throughout.
- Combine Dry Stuff:
- Stir together flour, baking powder and salt in a bowl until everything's well mixed. This stops lumps and makes sure the rising agents spread evenly in your batter.
- Mix Butter And Sugar:
- Beat your room temp butter and sugar in a mixer for a full two minutes until it gets noticeably lighter and fluffier. This puts air in the mix for soft cakes that rise well.
- Add Eggs Slowly:
- Put eggs in one at a time on low speed, waiting until each one's fully mixed before adding another. This keeps the batter from breaking and holds the air needed for fluffy cakes.
- Mix Wet And Dry Parts:
- Add flour mix and milk mix back and forth, starting and ending with flour. Mix just until combined to avoid tough cakes.
- Bake Them Right:
- Fill your paper liners about two-thirds full and bake for 18 to 24 minutes, checking with a toothpick. They should bounce back when touched and look slightly golden at the edges.
- Brush With Tequila:
- While still warm, brush tequila on top of each cake. This adds the real margarita taste and keeps them moist. Let them soak it up for about five minutes before moving to a cooling rack.
- Whip Up Lime Frosting:
- Beat room temp butter until super light and fluffy, about three minutes. Slowly add powdered sugar and fresh lime juice, going back and forth until you get the perfect taste and thickness.
- Top Them Off:
- Pipe your frosting onto fully cooled cakes using a star tip for a fun look. Sprinkle with sanding sugar for sparkle and add just a few salt grains on top if you want that true margarita feel.

The tequila brush is hands down my favorite part of making these. I found out how key it was when I once didn't add enough lime and thought they lacked flavor. Adding the tequila not only gives them that real cocktail kick but also makes them super moist and helps them stay fresh longer.
Keeping Them Fresh
These boozy cupcakes will stay good at room temp in a sealed container for up to three days. The lime frosting keeps its shape nicely but tastes best in the first two days when the citrus flavor is strongest. Don't put them in the fridge unless your kitchen is super hot, as cold air can dry them out.
Do Stuff Ahead of Time
You can bake the cakes up to two days before you need to frost them. Keep the plain cakes in a sealed container at room temp, then add fresh frosting just before serving. The tequila soak actually makes them taste better after a day as it soaks fully into the cake.
Try Different Tastes
For a fruity change, try adding a tablespoon of orange zest to the mix for a Cadillac margarita style. Switch the tequila for orange liqueur if you want a milder taste without tequila. For a spicy kick, add a tiny bit of cayenne to the batter and top the frosting with a small jalapeño slice.
Ways to Serve Them
Show off these cupcakes on a plate with fresh lime slices and mint leaves to make them look amazing. Put some berries or tropical fruit on the side for a complete dessert. For a fun touch, offer a small dish of lime zest mixed with salt or sugar so guests can dip their cakes for extra flavor.

These fun cupcakes make the perfect treat for grown-up birthday bashes, backyard cookouts, or Cinco de Mayo parties. The mix of tangy lime, smooth frosting, and hint of tequila creates a fancy little dessert that captures all the magic of the popular cocktail in every bite.
