These Apple Crumb Muffins are fluffy and filled with chunks of apples. The crumb topping is perfectly crunchy and sweet. Make them in just 3 easy steps!
Preheat the oven to 400° F. Line muffin pan with baking liners. I recommend parchment paper liners, not the colorful cupcakes ones.
Peel apples and cut into ¼" chunks.
Bake muffins for 7 minutes. Then, without opening the oven door, lower the temperature to 375° F and bake muffins for another 13 to 15 minutes. The magic number for me was 14 minutes.
