Step 1

Preheat your oven to 350 degrees F. Grease your muffin tin with nonstick cooking spray or use cupcake/muffin liners.

Step 2

To make the muffins, cream together the butter and sugar in a large bowl with a hand or stand mixer. Beat the mixture for about two minutes.

Step 3

Add the baking powder, cinnamon, vanilla extract, and salt and mix just until combined.

Step 4

Add  eggs to the butter mixture, one at a time and mix just until combined.

Step 5

Add about half of the flour and half of the milk and mix just until combined. Add the remaining half and half and flour and mix while scraping edges until well combined.

Step 6

Spoon batter into your paper liners or greased muffin cups until they are about ¾ of the way full.

Step 7

Place the muffin pan in the preheated oven and bake the muffins for about 22-27 minutes. The muffins are done when a toothpick inserted into the middle of a muffin pulls out clean and edges of muffins are golden brown.

Step 8

Place the muffins on a wire rack to cool.

Step 9

In a medium bowl, mix the sugar and cinnamon together for the topping. In a separate small bowl, melt the butter.

Step 10

Once the doughnut muffins cool to room temperature, dunk them into the melted butter and then roll them in the cinnamon sugar mixture until they are nicely coated.
