In a large bowl whisk together flour, sugar, poppy seeds, baking powder, baking soda and salt. Set aside.
Add the dry ingredients to the liquid ingredients and whisk together just until combined and no streaks of flour remain and a very thick batter forms. Don’t overmix otherwise the batter will become dense. The batter will look very thick.
Divide the batter among the muffin cups among 18 muffin cavities. Use your finger or back of a small spoon to lightly spread the thick muffin batter evenly into the liner.
Bake at 425°F for 5 minutes, then reduce the oven temperature to 350°F and bake for another 12-13 minutes or until a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the pan for 5 minutes before transferring to a wire rack to cool.
