1. 1Preheat oven to 350°F (175°C).
2. 2For the cinnamon swirl: combine 2 tablespoons melted butter, 1 teaspoon ground cinnamon, and 1/3 cup brown sugar in a small bowl. Set aside.
3. 3For the cupcakes: In a large bowl, mix together 0.5 cup melted butter, 2 eggs, 0.75 cup milk, 0.5 cup granulated sugar, and 2 teaspoons vanilla extract.
4. 4Add 2 cups cake flour, 1.75 teaspoons baking powder, and a pinch of salt to the wet ingredients and mix until smooth.
5. 5Line a cupcake tin with 12 cupcake liners. Pour about 1.5 tablespoons of batter into each liner. Add about 0.5 teaspoon of the cinnamon swirl mixture and use a toothpick to swirl it around.
6. 6Top off each cupcake with more batter until 3/4 full and add another swirl of the cinnamon mixture. Swirl again with a toothpick.
7. 7Bake for 22-24 minutes or until a toothpick inserted in the center comes out clean. Let cupcakes cool completely.
