Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C and line a 12-cup muffin tin with paper liners. In a medium bowl, whisk together the flour, baking powder, and salt until well combined and aerated.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In the bowl of your stand mixer fitted with the paddle attachment, cream the butter and sugar together on medium-high speed for 3-4 minutes until pale and fluffy. This extended creaming process creates tiny air pockets that will help your cupcakes rise properly and create that tender crumb we're aiming for.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the eggs one at a time, beating well after each addition until fully incorporated. Scrape down the sides of the bowl between additions. The mixture should look smooth and satiny, not curdled. If it does curdle slightly, don't worry – the flour will bring it back together.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Pour in the vanilla extract and bourbon, mixing until just combined. The alcohol will partially bake off, leaving behind that wonderful bourbon flavor without overwhelming the cake.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Gradually add the flour mixture in three parts, alternating with the milk (begin and end with flour), mixing on low speed just until combined after each addition. Overbeating at this stage will develop gluten and make your cupcakes tough, so mix until the ingredients are just incorporated.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Divide the batter evenly among the cupcake liners, filling each about 2/3 full. Use an ice cream scoop for consistent portioning. Bake in the preheated oven for 16-18 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Allow the cupcakes to cool in the pan for 5 minutes before transferring to a wire rack to cool completely. The cupcakes must be completely cool before frosting to prevent the buttercream from melting.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>For the mint buttercream, first prepare the mint infusion. Finely chop the fresh mint leaves and rub them with a little of the measured sugar to release the oils. Let this mixture sit for 15 minutes to develop flavor. This technique extracts maximum mint flavor without adding bitterness.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>In a clean mixer bowl, beat the butter for the frosting on medium-high speed for 3 minutes until very pale and creamy. Add the powdered sugar in three batches, beating well after each addition. The slow incorporation prevents a sugar cloud and ensures a smooth texture.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Mix in the mint-sugar mixture, milk, and mint extract (if using). Add a tiny drop of green food coloring if desired for a pale mint color. Beat on high speed for 2-3 minutes until light and fluffy. The extended whipping time creates that silky, pipeable consistency.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>For the bourbon glaze, whisk together the powdered sugar and bourbon in a small bowl until smooth and pourable. The mixture should coat the back of a spoon but still flow smoothly.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Transfer the mint buttercream to a piping bag fitted with a large star tip. Pipe generous swirls onto each cooled cupcake, starting from the outside and working toward the center with even pressure.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Drizzle each frosted cupcake with a teaspoon of bourbon glaze, allowing it to cascade down the sides slightly. The glaze will set partially but remain slightly shiny and soft.</li><li class="MethodStepper"><h4 class="step-title">Step 14</h4>Garnish each cupcake with a small fresh mint leaf or a crystallized mint leaf for an elegant finish. For the authentic mint julep experience, serve these sophisticated cupcakes slightly chilled, as the cool temperature enhances the refreshing mint flavor against the warming bourbon notes.</li></ol>
