Preheat oven to 375 degrees. Add flour, sugar, baking powder and 1/2 tsp salt into a large bowl. Mix together. Add in the cheese and stir together so cheese is coated. In a separate bowl, add in the egg and lightly beat it, add in the milk and 1/4 Cup of the melted butter, whisk until combined.
Add wet mixture to the dry mixture and stir with a large spoon until just mixed. There might be some small lumps and that is okay, we just don't want any dry patches.
Evenly divide batter into 12 servings in a muffin tin that is lined or that has been sprayed with baking spray. Bake for 20 - 25 minutes, until lightly golden brown on top. Place tin on wired rack to cool.
Take the additional 1/4 Cup of melted butter and mix in the pinch of salt and 1/4 tsp garlic powder. Brush mixture on top of each muffin evenly. Serve warm, enjoy!
