Preheat oven to 375°F (190°C) and line a 12-cup muffin tin.
Whisk flour, sugar, baking powder, baking soda, and salt in a bowl.
In another bowl, whisk eggs, butter or oil, milk or yogurt, vanilla, and pistachio paste.
Fold wet ingredients into dry until just combined. Gently fold in pistachios.
Divide batter evenly, filling liners about ¾ full.
Bake 18–22 minutes, until golden and a toothpick comes out clean. Cool slightly before serving.
