01 - Preheat oven to 350°F. Grease a 12-cup mini muffin pan or mini cake molds thoroughly.
02 - Whisk together flour, baking powder, and salt in a medium bowl. Set aside.
03 - Beat butter and sugar in a large bowl until light and fluffy, approximately 2-3 minutes.
04 - Add eggs one at a time, beating well after each addition. Stir in lemon zest, lemon juice, and vanilla extract.
05 - Add half the dry ingredients to the wet mixture, mixing gently. Pour in milk, then add remaining flour mixture. Mix until just combined—avoid overmixing.
06 - Divide batter evenly among prepared molds, filling each about 2/3 full. Bake for 18-20 minutes until a toothpick inserted in the center comes out clean.
07 - Let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
08 - Gently warm milk with lavender in a small saucepan over low heat for 2-3 minutes without boiling. Remove from heat, let steep for 5 minutes, then strain to remove lavender buds.
09 - Whisk together powdered sugar, lavender-infused milk, and lemon juice until smooth and pourable. Add additional milk if needed to achieve desired consistency.
10 - Spoon or drizzle glaze over cooled mini lemon cakes. Garnish with extra lavender buds or lemon zest if desired. Allow glaze to set before serving.
