Ingredients
Scale
- 1 1/2 cups (190g) all-purpose flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 cup (115g) unsalted butter, melted and cooled
- 1/2 cup (100g) granulated sugar
- 1/2 cup (100g) packed light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup (120ml) sour cream or plain yogurt
- 1 1/2 cups (about 180g) peeled and diced apples (about 2 medium apples, firm varieties like Granny Smith or Honeycrisp)
- For the crumb topping:
- 1/2 cup (100g) packed light brown sugar
- 1/4 cup (50g) granulated sugar
- 1 teaspoon ground cinnamon
- 6 tablespoons (85g) unsalted butter, melted
- 3/4 cup (95g) all-purpose flour
Instructions
- Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease well.
- Make the crumb topping: In a medium bowl, mix brown sugar, granulated sugar, and cinnamon. Stir in melted butter until combined. Add flour and stir until crumbly. Set aside.
- In a large bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.
- In another bowl, whisk melted butter with granulated sugar and brown sugar until combined. Add eggs one at a time, then vanilla and sour cream; mix until smooth.
- Add wet ingredients to dry ingredients and stir just until combined. Fold in diced apples gently.
- Divide batter evenly among muffin cups, filling each about 3/4 full.
- Press crumb topping evenly over each muffin.
- Bake for 5 minutes at 425°F (220°C), then reduce oven temperature to 350°F (175°C) and bake for an additional 15-20 minutes or until a toothpick inserted in the center comes out clean.
- Cool muffins in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Notes
For best results, use firm apples like Granny Smith or Honeycrisp to maintain texture. Press the crumb topping firmly on the batter for a crunchy top. The initial high oven temperature helps create tall muffin tops.
