Preheat the oven to 375℉. Prepare 12 muffin tins with liners.
Hull and dice the strawberries. Toss the strawberries with 2 teaspoons of flour (this will prevent sinking). Set aside ½ cup for the topping.
Combine the flours, baking powder, cinnamon, and salt in a large mixing bowl. Set aside.
Whisk together eggs, strawberry puree, maple syrup, Greek yogurt, oil, and vanilla in a medium mixing bowl.
Make a well in the dry ingredients and pour the wet ingredients into the dry ingredients. Mix until the dry ingredients are just incorporated (there can be a few streaks of flour). Fold in 1½ cups of strawberries.
Spoon the batter into the muffin tins, filling nearly to the top. Distribute the remaining ½ cup of strawberries on the tops of the muffins. Sprinkle the centers with turbinado sugar, if desired. Avoid the edges to prevent sticking.
Bake the muffins for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean and the tops are lightly golden. Allow the muffins to cool inside the muffin tins on a cooling rack 10 minutes before removing them from the muffin tin. Enjoy!
