Preheat your oven to 180°C (350°F) and line your tray with muffin liners or grease with butter.
In a medium-sized mixing bowl, sift and combine all the dry ingredients: flour, baking powder, cinnamon powder, sugar, and brown sugar.
Using another large bowl, combine and mix eggs, milk, vanilla extract, and melted butter.
Add the dry ingredients with the wet ones and mix just enough to combine.
Spoon some muffin batter into the muffin tins at about 2/3 of the liners.
For the toppings, combine sugar and cinnamon powder in a small bowl.
Top each muffin with about 1/4 to 1/3 teaspoon of the sugar-cinnamon mix.
Place your tray in the middle of the oven for 20 to 23 minutes or until the top becomes darker in color.
Remove each cinnamon muffin from the tin and serve.
