Peach Pecan Muffins in 40 Minutes

Instructions:

1. Preheat the oven to 425°F (218°C) and line a 12-cup standard muffin tin with paper liners or grease thoroughly with butter.
2. Prepare the peaches by peeling and dicing them into ¼ inch pieces.
3. In a large bowl, whisk together the 250g flour, 150g sugar, baking powder, baking soda, and salt.
4. In a medium bowl, whisk together the melted butter, buttermilk, egg, and vanilla extract until smooth.
5. Pour the wet ingredients into the dry ingredients and fold gently with a spatula until just combined; stop while a few streaks of flour remain to ensure tenderness.
6. Gently fold in the diced peaches using a toss-and-fold method to prevent them from sinking.
7. In a small bowl, combine the 60g flour, 100g brown sugar, chopped pecans, and cinnamon.
8. Add the cold cubed butter to the crumble mixture and use a pastry cutter or fork to rub the butter into the dry ingredients until a sandy texture forms.
9. Divide the batter evenly among the muffin liners and top each with a generous portion of the pecan crumble.
10. Bake according to the temperature settings (starting high for the dome) for approximately 25 minutes.
