01 - Preheat your oven to 350°F. Grease a 12-cup mini muffin pan or mini cake molds thoroughly with cooking spray or butter.
02 - In a medium bowl, whisk together the all-purpose flour, baking powder, and salt until well combined. Set aside.
03 - In a large bowl, beat the softened butter and granulated sugar together using an electric mixer or whisk until light and fluffy, about 2-3 minutes.
04 - Add eggs one at a time, beating well after each addition. Stir in lemon zest, lemon juice, and vanilla extract until fully incorporated.
05 - Add half of the dry ingredients to the wet mixture and mix gently. Pour in the milk, then add the remaining flour mixture. Mix until just combined—do not overmix.
06 - Divide batter evenly among the prepared mini cake molds, filling each about 2/3 full to allow for rising during baking.
07 - Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
08 - While cakes cool, gently warm the milk with dried lavender in a small saucepan over low heat for 2-3 minutes (do not boil). Remove from heat and let steep for 5 minutes, then strain to remove lavender buds.
09 - In a bowl, whisk together powdered sugar, lavender-infused milk, and lemon juice until smooth and pourable. Add more milk 1 teaspoon at a time if needed for desired consistency.
10 - Spoon or drizzle glaze over cooled mini lemon cakes. Garnish with extra lavender buds or lemon zest if desired. Let glaze set for 10-15 minutes before serving.
