In a medium mixing bowl, whisk together the flour, salt, baking powder, black pepper, garlic powder, and onion powder until fully combined.
Add the softened butter to the dry ingredients and use your fingers or a pastry cutter to work it into the flour mixture until it resembles coarse crumbs.
Gradually pour in the milk, stirring gently with a wooden spoon or spatula, until a soft dough forms. The dough should be slightly sticky but hold its shape when scooped.
Using a tablespoon or a small ice cream scoop, drop rounded portions of the dough (about 1-2 tablespoons each) onto a greased baking sheet or into a simmering soup or stew.
If baking, bake the dumplings in a preheated 400°F oven for 15-18 minutes, or until they are golden brown and cooked through. If cooking in a soup or stew, cover and simmer for 10-12 minutes until the dumplings are fluffy and no longer doughy in the center.
