01 - Preheat oven to 400°F. Grease a 24-cup mini muffin tin thoroughly with melted butter or nonstick cooking spray, ensuring each cup is well-coated for easy removal.
02 - In a medium mixing bowl, whisk together flour, sugar, baking powder, baking soda, and salt until evenly distributed.
03 - In a separate bowl, whisk together buttermilk, egg, melted butter, and vanilla extract until completely smooth and well incorporated.
04 - Pour wet ingredients into dry ingredients. Mix gently with a spatula or wooden spoon just until combined—some small lumps are acceptable. Avoid overmixing to ensure tender poppers.
05 - If desired, gently fold in chocolate chips or blueberries until evenly distributed throughout the batter.
06 - Spoon batter into prepared mini muffin tin, filling each cup approximately 3/4 full. Use a small cookie scoop or tablespoon for consistent portioning.
07 - Bake for 8 to 10 minutes until tops are golden brown and a toothpick inserted into the center comes out clean.
08 - Allow poppers to cool in the tin for 2 minutes before carefully removing. Serve warm with maple syrup, melted chocolate, or fruit preserves for dipping.
