Preheat oven to 425°F. Line two baking sheets with parchment.
Combine water, milk, butter, and salt in a saucepan. Bring to a strong simmer.
Stir in flour all at once. Mix vigorously until a smooth ball forms.
Cook dough over low heat, stirring, until slightly dry and a film forms, about 2 minutes.
Let cool 3 minutes. Beat in the eggs gradually until glossy and stretchy.
Fold in cheddar, black pepper, paprika, and chives until evenly mixed.
Scoop tablespoon mounds onto the sheets, spacing about 2 inches apart.
Bake 10 minutes, then reduce to 375°F. Bake 12–15 minutes until puffed and deeply golden. Avoid opening early.
Cool 5 minutes on the pan. Serve warm while crisp.
Notes
Variation: Swap half the cheddar for grated Gruyère or add a pinch of cayenne for extra heat. To make ahead, freeze scooped, unbaked puffs on a sheet, then bake from frozen, adding 2–3 minutes.This recipe is an original creation inspired by classic Easy Cheese Puff Recipes flavors.
