1-Getting started with these cinnamon sugar donut muffins: Begin by preheating it to 350 degrees Fahrenheit and preparing your muffin tin with grease or paper liners. This sets the stage for baking treats that mimic the soft texture of classic donuts.

2-In a large bowl, whisk together 1 1/2 cups flour, 1/2 cup sugar, 1 1/2 teaspoons baking powder, 1/8 teaspoon salt, 1/2 teaspoon cinnamon, and 1/4 teaspoon nutmeg until everything is evenly mixed. In another bowl, beat 1 large egg and then stir in 1/2 cup milk, 1 teaspoon vanilla extract, and 1/3 cup melted and cooled butter to create a smooth wet mixture.

3-Combine the wet ingredients with the dry ones, stirring just until moistened to keep the muffins tender over-mixing can make them tough. Spoon the batter into the muffin cups, filling them about half to three-quarters full, then bake for 20-25 minutes until they’re golden and a toothpick comes out clean. Once done, let them cool for 5 minutes before dipping in the topping: mix 1/3 cup sugar with 2 teaspoons cinnamon, melt 5 tablespoons of butter, and coat the warm muffins for that signature finish.
