The vanilla in this muffin adds a bit of sweetness, while the cheese adds a savory taste. Serve them as a side dish or eat them for breakfast!
In a bowl, mix all the ingredients (except cheese) until well combined. Grease puto molds or line with paper cups.
Pour or fill the mixture in the prepared molds (at least 2/3 of the mold) and top with cheese.
Prepare the steamer by bringing water to a boil over medium-high heat. Place the molds into a steamer. Cover with cheesecloth to avoid water drip.
Steam for 15 minutes or until toothpick inserted comes out clean.
