Preheat oven to 425°F degrees. Spray 12 muffin cups or muffin paper liners with non-stick cooking spray.
In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar.
In a medium bowl, whisk the eggs with the yogurt, melted butter, lemon juice, lemon zest and vanilla extract just until combined.
Pour the wet ingredients into the dry ingredients and stir with a wooden spoon or a rubber spatula just until combined. Do not over mix.
Add fresh or frozen raspberries to muffin batter and fold in just enough to distribute them around. The batter should be thick..
Divide the batter evenly between the muffin cups using a large cookie scoop to fill muffin tins almost to the top.
Bake muffins for 3 minutes at 425°F degrees and then reduce the oven temperature to 350°F. Continue baking for an additional 12-17 minutes until a toothpick inserted into the center of the muffin comes out clean.
Cool muffins for 10 minutes and then move to a wire rack to cool completely. When the muffins are cooled, make the lemon glaze to drizzle on top of your lemon raspberry muffins.
