1 tablespoon coarse sugar for decorating (Optional)
Instructions
Preheat oven to 350 degrees F (175 degrees C). Grease a 5x9-inch loaf pan and line with parchment paper.
Beat banana, sugar, butter, and shortening together until smooth; mix in eggs. Stir fresh orange zest, dried orange peel, nutmeg, and vanilla extract into mixture. Gradually stir flour into moist ingredients. Fold chocolate and lavender into batter. Spoon batter into prepared loaf pan. Sprinkle coarse sugar crystals over batter.
Bake in the preheated oven until a toothpick inserted into the center of the loaf comes out clean, about 1 hour.
