Ingredients Needed

Here’s a quick look at what you’ll need to make these. You can find the full amounts and detailed instructions in the recipe card below.

Various baking ingredients including flour, powdered sugar, eggs, limes, butter, oil, vanilla extract, and other liquids arranged in bowls on a white surface.

How to Make It

Before you start, preheat your oven to 350°F and line a muffin tin with cupcake liners.

A glass bowl of yellow cake batter with a metal whisk inside, placed on a white surface next to two whole limes.

Step 1: In a large bowl, whisk together cake mix, vegetable oil, margarita mix, tequila, and eggs. Stir until well combined.

A muffin tin lined with green paper cups, each filled with yellow batter, sits on a white surface.

Step 2: Fill the cupcake liners, about 2/3-3/4 full. Discard any remaining cupcake batter. Bake for 15-18 minutes.

Twelve plain yellow muffins cooling on a black wire rack, placed on a white marble surface.

Step 3: Remove the cupcakes and place them on a wire rack to cool.

A glass bowl containing whipped or creamed butter on a white surface.

Step 4: For the frosting, beat the softened butter in a large mixing bowl until smooth.
Add vanilla and lime juice, and mix well to combine. Add powdered sugar, about 1 cup at a time, mixing well, until it is all incorporated.

Cupcakes with white frosting, each topped with a lime wedge and a green-striped straw, arranged on a wooden board with a green cloth in the background.

Step 5: Add the frosting to a piping bag fitted with a 1M star tip, then frost the cupcakes.

Optional decoration: Add a thin lime slice to each cupcake and top with a straw.

Recipe Tips

Use softened butter when making the frosting, as cold butter tends to form more lumps if you’re not experienced. If using cold butter, cut it into small pieces and beat it with a stand mixer until fluffy.

Don’t overfill your cupcake liners or they’ll dome up and overflow. 2/3 full is the sweet spot.

Fresh lime juice is best for the frosting. And if you want to get fancy, a tiny pinch of flaky sea salt on top of the frosting really adds that proper margarita finish.
