Preheat to 375℉, grease a mini muffin tin or line with paper liners. Set aside.
In a bowl, mix the flour, baking powder, salt, garlic & onion powder, and sugar. Set aside.
1 ½ cups all-purpose flour, 2 tsp baking powder, ½ tsp salt, ½ tsp garlic powder, ¼ tsp onion powder, 1 ½ tbsp granulated sugar
In a separate bowl, whisk together the egg, milk, greek yogurt, and melted butter.
1 large egg, ½ cup milk, ½ cup plain greek yogurt, 4 tbsp butter
Use a rubber spatula to gently fold the dry ingredients into the wet, until just mixed- be careful not to over mix! Fold in the shredded cheddar, crumbled bacon, and chives.
1 cup sharp cheddar cheese, ½ cup cooked & crumbled bacon, 2 tbsp freshly chopped chives
Fill each mini muffin tin about ¾ of the way. Bake for 12-15 minutes, or until a toothpick comes out clean.
Allow the muffins to cool in the pan for about 5 minutes, before removing them and letting them cool on a wire cooling rack for another 5+ minutes, or until ready to eat.
