Step 1

Preheat the oven to 350°F (177°C). Line a 12-cup muffin pan with cupcake liners.

Step 2

Whisk the flour, baking powder, and salt together in a large bowl. Set aside.

Step 3

With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on high speed in a large bowl until smooth and creamy, about 1 minute. Add the granulated sugar and beat on high speed for 2 minutes until creamed. Scrape down the sides and up the bottom of the bowl as needed. With the mixer running on low speed, add the eggs one at a time, then add the vanilla extract. Beat on medium-high speed until combined. Scrape down the sides and up the bottom of the bowl as needed.

Step 4

With the mixer running on low speed, slowly add some of the dry ingredients alternating with some of the milk until all is mixed. Increase to high speed and beat in the lime zest and juice until incorporated. Try to avoid overmixing.

Step 5

Pour/spoon the batter into the liners – fill only 1/2 – 2/3 full to avoid spilling over the sides. Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. For around 30 mini cupcakes, bake for about 11-13 minutes, same oven temperature. While still warm, brush finished cupcakes with tequila. This infuses extra tequila flavor. Allow the cupcakes to cool completely before frosting.

Step 6

In a large bowl using a handheld or stand mixer fitted with a whisk attachment, beat the butter on high speed until completely smooth and creamy, about 2-3 minutes. Add the confectioners’ sugar 1 cup at a time, beating on low at first then increasing to high speed. Once incorporated, add the next cup. Once creamy and combined, beat in the tequila, vanilla extract, lime flavoring, and pinch of salt on high speed. Taste. Add more salt or flavoring as needed.

Step 7

Frost cooled cupcakes. I used a Wilton 1M tip for these photos. (Another favorite is this Wilton #12 round tip.) Garnish with lime slices, lime zest, or coarse sugar.
