• Preheat the oven to 400° Fahrenheit and line 8 muffin cups with muffin liners or spray with cooking oil.
• To a large mixing bowl add the all-purpose flour, cinnamon, ginger, sugar, baking powder and salt. Mix. In a measuring cup, mix the milk, vanilla extract, egg, and olive oil until well blended.
• Pour into the bowl of dry ingredients and mix with a fork until just combined, being careful not to overmix. Fold in the chopped peaches.
• Fill the muffin cups ⅔ with the batter. Sprinkle with cinnamon sugar and extra coarse sugar if using. Fill any empty cavities with a few tablespoons of water.
• Bake for 15-20 minutes or until a toothpick inserted into the center comes out clean.

Air Fryer Method

• Follow steps 1-3 above. Scoop batter into silicone muffin cups filling them ⅔ full. Transfer to the air fryer and cook at 350°F (177°C) for 12 minutes. Insert a toothpick into the center to check for doneness, adding 1 minute at a time until cooked through if necessary. They may need up to 15 minutes.
