In a large bowl, add the gluten free flour, baking powder, salt, and whisk.
In a medium bowl, add white sugar, and cooled melted butter and stir.
Add milk, eggs, vanilla, and lemon zest to the sugar mixture. Stir.
Add the wet ingredients to the dry ingredients until fully combined.
Add the raspberries to the batter. Stir.
Cover the batter and allow it to hydrate (rest) for thirty minutes at room temprature. This will prevent a gritty texture.
Add muffin liners to a muffin pan. Scoop the batter evenly with an ice cream scoop or large cookie scoop.
Sprinkle the turbinado sugar over the top of each muffin, if using.
Bake in a preheated 375 degree F oven for 20-28 minutes or until a toothpick inserted comes out clean.
Leave the muffins in the tin for ten minutes. Remove and place a cooling rack for another ten minutes.
Enjoy the muffins within a day. Otherwise, freeze the cooled muffins to enjoy at a later date.
