This lavender honey angel food cake recipe is a light and fluffy dessert option. Using a food processor, blend together flour, sugar, and salt. In a separate bowl, whisk together egg whites, honey, lavender, and cream of tartar until stiff peaks form. Fold the dry ingredients into the egg white mixture and pour into an ungreased angel food cake pan. Bake for 35-40 minutes. Once cooled, dust with powdered sugar and garnish with fresh lavender sprigs.
