01 - Preheat the oven to 350°F. Grease and flour an 8-inch round cake pan.
02 - Whisk together flour, baking powder, and salt in a bowl. Set aside.
03 - Beat softened butter and sugar in a large bowl until light and fluffy. Add eggs one at a time, mixing well after each addition. Stir in lavender and vanilla extract.
04 - Alternate adding the flour mixture and milk to the butter mixture, beginning and ending with the flour mixture. Mix until just combined, being careful not to overmix.
05 - Pour batter into the prepared pan and smooth the top evenly. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
06 - While the cake bakes, simmer water, sugar, and lavender buds in a small saucepan for 3 minutes. Strain the syrup and set aside to cool slightly.
07 - Let the cake cool in the pan for 10 minutes. Poke small holes across the surface and brush with warm lavender syrup. Allow to cool completely.
08 - Whisk powdered sugar with lemon juice and chopped lavender until smooth and drizzling consistency is achieved.
09 - Drizzle the glaze evenly over the cooled cake. Allow the glaze to set before slicing and serving.
