Preheat oven to 350F. Line a 12-cup muffin pan with wrappers and set aside.
In a large bowl, beat sugar, melted butter, eggs, yogurt, vanilla, and milk until smooth. In a separate bowl, combine 2 cups flour, baking powder, and salt.
Fold flour mixture into liquid until batter is just combined. In a small bowl, toss strawberries with remaining 1 tablespoon flour until evenly coated. Gently fold strawberries and chocolate chips into muffin batter.
Divide muffin batter between prepared cups, filling each cup to the brim with batter. Bake muffins at 350F 20-25 minutes until muffins are golden brown and a toothpick inserted in center of a muffin comes out clean.
Cool muffins on a wire cooling rack and serve. Enjoy!
