Preheat the oven to 425°F. Line a muffin pan with 9 liners, spray the liners and top of the pan with nonstick spray to ensure they come out of the pan.
Place the lemon zest and sugar in a large bowl, rub together or beat together until fragrant and combined.
Add the melted butter, vanilla extract, eggs, and milk in the bowl, whisk until combined.
Whisk together the flour, baking powder, and salt. Add it to the wet ingredients.
Whisk until combined and a batter just forms. Do not over mix.
Fold in the chopped strawberries, making sure they are distributed evenly.
Divide the batter evenly over the 9 muffin liners. It will look like a lot of batter for one liner, it’s not! This is how you get big tops. Top with a little more sugar (I like coarse raw sugar) to just coat the tops.
Place in the oven on the center rack of the oven to ensure even baking, avoiding placement too close to the top or bottom and immediately turn the oven temperature down to 400°F. Bake for about 18-22 minutes or until a toothpick comes out clean, check earlier if your oven runs hot.
Let cool before removing them from the pan.
