Fresh strawberries are abundant in these bakery style muffins. With a fluffy and tender muffin, fresh berries, and a crumble topping, you're going to love these easy strawberry muffins.
Preheat. Preheat the oven to 450°F and line a muffin pan with paper liners. Set aside.
Make crumble topping. In a medium bowl, whisk together the flour, granulated sugar, and cinnamon. Cut in the cold butter using forks or a pastry blender until coarse crumbs form. Set aside.
Mix dry ingredients. In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
Mix wet ingredients. In a large bowl, whisk together the sugar, vanilla extract, and sour cream. Stir in the melted butter quickly, then add the egg and orange zest if using.
Combine batter. Add the dry ingredients to the wet ingredients and fold just until combined. The batter will be thick. Gently fold in the strawberries.
Fill muffin pan. Scoop the batter into the muffin cups, filling about ⅔ full. Sprinkle the crumble topping over each muffin and press gently to adhere.
Bake. Bake at 450°F for 7 minutes, then reduce the oven temperature to 375°F and continue baking for 5 to 7 minutes, until a toothpick inserted into the center comes out clean.
Cool. Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Glaze. Whisk together the powdered sugar, vanilla extract, and milk until smooth. Drizzle over the cooled muffins and allow the glaze to set, about 10 minutes.
Notes
Two-stage baking. Starting at a higher temperature helps create domed tops, crisp crumble, and a fluffy interior.
Doneness. Avoid opening the oven early. Test with a toothpick near the end and add 1 to 2 minutes if needed.
Storage. Store in the refrigerator for up to a few days. Best enjoyed within 3 to 5 days for optimal texture and flavor.
