You can bake incredibly moist, fluffy pistachio muffins with tall domes right in your home kitchen. This easy recipe uses a simple ingredient to guarantee a bakery-quality result perfect for breakfast or brunch.
Preheat your oven to 400 degrees Fahrenheit. Line a 12-cup muffin tin with paper liners or grease well.
In a large bowl, whisk together the flour, baking powder, baking soda, salt, granulated sugar, and the entire package of instant pistachio pudding mix. This dry mix is key for flavor and texture.
In a separate medium bowl, combine the milk, vegetable oil, sour cream, eggs, and vanilla extract. Whisk until just combined.
Pour the wet ingredients into the dry ingredients. Mix with a spatula until the batter is just combined. Do not overmix; a few lumps are fine.
Gently fold in the 1/2 cup of chopped pistachios meant for the batter.
Prepare the topping by mixing the remaining 2 tablespoons of sugar with the 1/4 cup of chopped pistachios.
Fill each muffin cup about two-thirds full. Sprinkle the pistachio sugar topping evenly over the top of the batter in each cup.
Bake at 400 degrees Fahrenheit for 5 minutes. This initial high heat helps create the tall dome.
Reduce the oven temperature to 375 degrees Fahrenheit and continue baking for another 15 to 18 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Notes
For the tallest dome, make sure your oven is fully preheated to 400 degrees Fahrenheit before placing the muffins in for the initial 5 minutes.
You can substitute the vegetable oil with melted unsalted butter for a richer flavor, though the oil aids in moisture retention.
If you want a more vibrant green color, add 1-2 drops of green food coloring to the wet ingredients.
