These Cinnamon Streusel Apple Muffins are packed with soft apples and lots of warm cinnamon! The crumb topping makes these muffins almost like individual coffee cakes. They are super moist and flavorful! Perfect for a fall brunch!
Preheat oven to 350°F. Line a 12-cup muffin pan with liners or spray the pan generously with nonstick spray.
Prepare topping: Mix the brown sugar, ground cinnamon, and flour in a medium bowl. Pour in the melted butter and combine with a fork or whisk until crumbly. Set aside.
Whisk the flour, salt, baking soda, baking powder, and cinnamon in a medium bowl. Set aside.
In a large mixing bowl, cream the butter and granulated sugar on high speed for 2 minutes.
Add the eggs, vanilla extract, and sour cream and mix on medium speed for 1 minute. Scrape the sides.
Stir in the flour on low speed until just combined. Then mix in the apples. The batter will be thick.
Portion the batter into each muffin cup, filling to the top of the liner. Divide the topping mixture over each muffin and gently press into the batter.
Bake for 22-25 minutes, or until a toothpick inserted comes out clean. Remove from the oven and cool for 10 minutes, then remove to a wire cooling rack to cool completely.
To prepare the icing, whisk the confectioners’ sugar, milk, and vanilla extract in a small bowl. Drizzle over the muffins and serve.
