Ingredients
Method
- Preheat oven to 400°F and prepare a cupcake pan with paper liners.
- Make crumb topping: whisk flour, sugar, brown sugar, and cinnamon. Add melted butter, stir until crumbly, and refrigerate.
- Mix dry ingredients: flour, baking powder, and salt. Set aside.
- Combine wet ingredients: sugar, eggs, sour cream, oil, and vanilla. Fold into dry ingredients.
- Add peaches to batter, reserving 1 cup for topping. Fill muffin tins 2/3 full, top with peaches and crumb mixture.
- Bake at 400°F for 5 minutes, then reduce to 375°F for 15 minutes. Cool and glaze with powdered sugar mixture.
Notes
For best results, use fresh peaches and let muffins cool before glazing. Store in an airtight container for up to 3 days.
