Homemade Lemon-Lavender Lemonade
Cut half a lemon into slices and muddle them with some cane sugar. Fill glass with ice cubes and sparkling water, then add a dash of lavender syrup at the end. Stir to combine.
Set butter, eggs, and yogurt out to reach room temperature. Preheat oven to 175°C/350°F. Finely chop lavender. Butter a loaf pan and line it with a strip of parchment paper long enough to hang over short sides of the pan. Whisk together flour, baking powder, and salt; set aside. Cream butter, then add sugar, lemon zest, and lavender. Beat until light and well combined, then add eggs one at a time.
In a small bowl, combine yogurt with some of the lemon juice and vanilla extract. Fold half of dry ingredients into butter mixture, then add yogurt. Add rest of flour and stir to combine. Pour batter into loaf pan and bake for about 35 minutes, or until a toothpick inserted into center of the cake comes out clean. Let cool in pan for 15 minutes before turning cake out of pan. Let cool completely.
Meanwhile, stir together powdered sugar, remaining lemon juice, and vanilla until smooth. Drizzle glaze over cooled cake, sprinkle with lavender buds, and let set before slicing and serving.
