Preheat oven to 400 degrees F. Add eggs, oil, and zest from the lemon to a mixing bowl. Measure milk in a liquid measuring cup and squeeze the juice from the lemon into it. Set aside for 1 minute, then add to the bowl with the other ingredients and mix to combine.

In a separate large bowl combine dry ingredients: flour, sugar, baking powder, and salt in a large bowl. Stir the wet ingredients into the flour mixture, being careful not to over-mix the batter.

Fold in the raspberries.

Line a muffin tin with liners, or grease with non-stick cooking spray. Fill muffin cups 3/4 full. Bake at 400 degrees F for 16-20 minutes or until a toothpick inserted in the center comes out with few crumbs.

In a small bowl, whisk together the confectioners sugar and 2 tablespoons lemon juice. (if you want the glaze even thinner, add an extra tablespoon of lemon juice). Allow the muffins to cool for a few minutes before drizzling with glaze.
