Preheat your oven to 350°F and line a 12-cup muffin tin with cupcake liners.
Pour the all-purpose flour, baking powder, and salt into a large bowl and mix until the dry ingredients are well-combined then set the bowl aside.
If you have an electric mixer, fit the paddle attachment and put in the butter and sugar. Cream them at a medium speed until the batter is pale yellow in color. You can also cream by hand but using the electric mixer can make the process take 3-5 minutes.
Once the butter and sugar are creamed, mix in the eggs and vanilla extract then add the codensed milk. Make sure to mix the ingredients well until they are fully incorporated.
Lower the speed of your electric mixer and gradually add the dry ingredients.
Add 3/4 cup grated cheese into the mixture and mix everything until it is well combined.
Scoop the batter onto the prepared muffin tin until cups are 3/4 full.
Top the cupcake batter with 1 to 2 teaspoons of grated cheese then bake for 25-30 minutes. You can also test the cupcakes by inserting a toothpick in the center and see if it comes out clean.
When the cupcakes are ready, remove them from the pan and let them cool on a wire rack. Once the cupcakes are cooled, serve them fresh.
