Cook the turkey bacon until crispy, then let it cool slightly before chopping it into small pieces.
In a large mixing bowl, whisk together the flour, baking powder, and salt to evenly combine the dry ingredients.
Add the shredded cheddar and chopped bacon to the dry mixture, stirring gently to distribute evenly.
In another bowl, whisk the eggs until well blended, then stir in the milk and melted butter until smooth.
Pour the wet mixture into the dry ingredients, folding gently with a spatula until just combined; the batter will be slightly lumpy.
Using a cookie scoop or spoon, divide the batter evenly into the prepared muffin tin, filling each cup about 3/4 full.
Place the muffin tin in a preheated oven at 375°F (190°C) and bake for about 20 minutes, until the tops are golden brown and a toothpick inserted in the center comes out clean.
Remove the muffins from the oven and let them cool in the tin for a few minutes before transferring to a wire rack to cool completely.
Once cooled slightly, serve these savory muffins warm or at room temperature, enjoying the crispy bits of bacon and gooey cheese inside.
