Preheat oven to 375 degrees. Spray cooking spray into mini muffin tins. In a medium bowl, combine melted butter and sugar. Then add the cinnamon, vanilla & milk.Once that is combined, add the flour and baking powder and stir until it is well incorporated. With a small scooper or spoon, scoop batter into tins and fill almost to the top. Bake for 15-17 minutes or until a toothpick can be inserted in the middle of one and comes out clean.

Once they are done, remove them from the pan and let cool on a cooling rack. In a separate small bowl, mix together icing ingredients until combined. Dip the top of the cooled muffins in the icing and let them set. Enjoy!!
