Peach Streusel Muffins in 28 Minutes

Instructions:

1. In a small bowl, combine 1/2 cup flour, brown sugar, and cinnamon. Rub the cold cubed butter into the mixture using fingertips or a fork until it resembles coarse sand with a few pea-sized lumps. Set aside.
2. In a large bowl, whisk together the remaining flour, granulated sugar, baking powder, baking soda, and salt.
3. In a medium bowl, beat the egg, then whisk in the milk, oil, vanilla, and lemon juice.
4. Pour the wet ingredients into the dry ingredients and fold together with a spatula until just combined; the batter should remain slightly lumpy.
5. Gently fold the diced peaches into the batter.
6. Spoon the batter into a 12-cup standard muffin tin, filling each cup about 3/4 full.
7. Generously sprinkle the cinnamon streusel topping over each muffin, pressing lightly.
8. Bake at 400°F (200°C) for 15–18 minutes until the tops are mahogany-colored and a toothpick comes out clean.
9. Let the muffins cool in the pan for 5 minutes before transferring them to a wire cooling rack.
