Method
Prep oven and chill components
- Preheat the oven to 375°F and line a 12-cup muffin tin.
- Beat the cream cheese filling ingredients together until smooth, then refrigerate while you prepare the rest.
- Make oat crumble by combining the dry ingredients and cutting in the cold butter until crumbly, then refrigerate.
Mix muffin batter and assemble
- Whisk together the flour, baking powder, baking soda, cinnamon, and salt until evenly combined.
- Whisk the melted butter, brown sugar, eggs, sour cream, milk, and vanilla until smooth and glossy.
- Fold the flour mixture into the wet ingredients just until no dry streaks remain.
- Fold in the finely diced apples.
- Fill each muffin cup halfway with batter.
- Add about a teaspoon of cream cheese filling to the center of each muffin.
- Cover each with more batter until the filling is enclosed.
- Top each muffin with oat crumble, pressing lightly so it sticks.
Bake
- Bake at 375°F for 22 to 25 minutes, until the tops are golden and the center looks set.
Notes
Pro tip: Chill the cream cheese filling and crumble so they stay distinct in the batter—warm ingredients can blur together. Store airtight in the refrigerator up to 4 days; rewarm 10 to 15 minutes at 300°F. Freeze baked muffins up to 2 months. For a lighter option, use reduced-fat cream cheese and sour cream (texture remains best when you refrigerate the filling).
