Prep and chill components
- Preheat the oven to 375F, then line a 12-cup muffin tin. Set up so the batter can be mixed right after chilling steps.
- Beat cream cheese filling ingredients together until smooth, then refrigerate. Chill until firm enough to spoon, about 10-15 minutes.
- Make the oat crumble by combining the dry ingredients and cutting in cold butter until crumbly, then refrigerate. You want small clumps that will melt into a crisp top.
Mix the muffin batter
- Whisk flour, baking powder, baking soda, cinnamon, and salt in a mixing bowl. Mix until the color is evenly speckled with cinnamon.
- Whisk melted butter, brown sugar, eggs, sour cream, milk, and vanilla until smooth. The mixture should look glossy and fully combined.
- Fold in the flour mixture, then fold in diced apples. Stop mixing when no dry streaks remain so the muffins stay tender.
Fill, top, and bake
- Fill muffin cups halfway with batter, then add a teaspoon of cream cheese filling to the center. Leave a little space around the filling so it stays pooled.
- Cover the cream cheese with more batter, then top each muffin with oat crumble. Press lightly so the crumble adheres.
- Bake for 22-25 minutes at 375F until the tops are golden. A toothpick inserted near the center should come out mostly clean with moist crumbs, not wet batter.
Notes
Pro tip: keep the cream cheese filling and oat crumble cold so they hold their shape and create a distinct swirl and crunch. Refrigerate leftover muffins in a sealed container for up to 3 days; rewarm 10-15 minutes at 300F for best texture. Freezing is yes—freeze up to 2 months and thaw overnight in the fridge. Dietary swap: use Greek yogurt in place of sour cream for a slightly tangier, lighter muffin.
