These cinnamon roll muffins are warm and full of the same cinnamon flavor that you get with homemade cinnamon rolls but without all the extra work. Yes, please!
Mix the wet ingredients in a large bowl, then add the dry ingredients and whisk until the batter is thick.
Cinnamon Sugar Filling
In a small bowl, mix brown sugar and cinnamon.
Cream Cheese Filling
In another bowl, mix softened cream cheese with sugar, sugar, vanilla and egg yolk. Mix until smooth and just combined.
Muffin Assembly:
Line a muffin tin with 12 liners. Add a spoonful of batter to each liner, then a spoonful of cinnamon sugar. Add another spoonful of batter on top. Use a wet spoon to make a small well in the center and add a spoonful of cream cheese filling. Sprinkle more cinnamon sugar on top.
Bake at 400°F for 15–18 minutes until golden and a toothpick comes out clean. Cool for 5 minutes, then move to a rack to cool completely.
