01 - Preheat oven to 375°F. Line a baking sheet with parchment paper or lightly grease a mini muffin tin.
02 - In a large bowl, whisk together flour, baking powder, baking soda, salt, ranch seasoning mix, smoked paprika, and cayenne pepper until evenly blended.
03 - Add shredded cheddar and grated Parmesan cheese to the flour mixture and toss to distribute evenly.
04 - In a separate bowl, whisk eggs, buttermilk, and melted butter until well combined and smooth.
05 - Pour the wet ingredients into the bowl with the dry ingredients; stir gently until just incorporated.
06 - Fold in the chopped jalapeños and chives, if using. Be careful not to overmix.
07 - Using a small cookie scoop or spoon, form dough into 1.5-inch balls and place onto the prepared baking sheet or into muffin tin wells.
08 - Bake for 16 to 18 minutes, or until golden brown and a toothpick inserted in the center comes out clean.
09 - Allow muffin balls to cool slightly before serving. Enjoy warm or at room temperature.
