Preheat & Prep:Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or spray with nonstick cooking spray.
Make Streusel:In a small bowl, combine flour, sugar, cinnamon, and softened butter. Mix until crumbly and set aside.
Mix Muffin Batter:In a large bowl, whisk together flour, sugar, salt, baking powder, and pumpkin pie spice.In another bowl, combine melted butter, sour cream, pumpkin purée, egg + yolk, milk, and vanilla.Gently fold the wet ingredients into the dry ingredients until just combined. Be careful not to over mix.
Prepare Cream Cheese Filling:Beat the cream cheese, sugar, and vanilla until smooth.
Assemble Muffins:Fill each muffin liner about halfway with pumpkin batter.Add about 1 tablespoon of cream cheese filling in the center.Top with more pumpkin batter until the liner is ¾ full.Sprinkle generously with streusel. Alternatively, you can divide the pumpkin batter evenly between 12 caverns, make a small hole at the top of each muffin batter with the back of a tablespoon, and plop the cream cheese right in there! Then cover with streusel. This is an easier method in my opinion. (Just note that the cream cheese will sit closer to the top than center of the muffins when baked).
Bake:Bake for 22-25 minutes, or until a toothpick inserted in the muffin (avoiding the cream cheese center) comes out clean.
Cool & Serve:Let muffins cool in the pan for 5 minutes before transferring to a wire rack. My personal favorite way to enjoy them is warm with salted Irish butter and a sprinkling of cinnamon and sugar!
