To make easy cupcakes, preheat your oven to 350°F (180°C). In a mixing bowl, whisk together 1 1/2 cups of all-purpose flour, 1 1/2 tsp of baking powder, and 1/4 tsp of salt. In another bowl, beat together 3/4 cup of granulated sugar and 1/4 cup of softened unsalted butter until fluffy. Add 2 large eggs, one at a time, beating after each, and 1 tsp of vanilla extract, and mix well. Gradually add the flour mixture alternating with 1/2 cup of milk, beating until smooth. Then, line a muffin tin with paper liners and fill each liner about 2/3 full with the batter. Bake for 18-20 minutes or until a toothpick inserted into the center of one of the cupcakes comes out clean. Allow cupcakes to cool completely before frosting and decorating.
