# Cooking Steps:
01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or lightly grease with nonstick spray.
02 - In a large bowl, whisk together all-purpose flour, granulated sugar, light brown sugar, baking powder, baking soda, salt, cinnamon, and nutmeg until evenly incorporated.
03 - In a separate bowl, whisk unsweetened applesauce, Greek yogurt, oil, eggs, vanilla extract, and milk until smooth and homogeneous.
04 - Pour wet ingredients into dry ingredients and stir gently until just combined, avoiding overmixing to maintain tender texture.
05 - In a small bowl, mix light brown sugar and ground cinnamon to create the cinnamon swirl mixture.
06 - Fill each muffin cup halfway with batter, sprinkle approximately 1/2 teaspoon of the cinnamon swirl over the batter, then top with remaining batter. Use a toothpick to gently swirl the cinnamon sugar into the batter.
07 - Combine all-purpose flour, light brown sugar, and cinnamon in a small bowl. Cut in cold diced butter using a fork or pastry blender until mixture is crumbly.
08 - Evenly distribute the streusel topping over each muffin prior to baking.
09 - Bake in preheated oven for 20 to 22 minutes or until a toothpick inserted into the centers comes out clean.
10 - Allow muffins to cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
