Step 1

Preheat oven to 350 degrees F (175 degrees C). Grease a 10-inch cast iron skillet.

Step 2

Combine flour, baking powder, and salt in a bowl. Set aside.

Step 3

Cream butter and 1 cup sugar with an electric mixer together in another bowl until light and fluffy. Add eggs, 1 at a time, mixing well after each addition. Add vanilla. Add dry ingredients and buttermilk alternately. Fold in strawberries. Transfer batter into the prepared skillet and smooth out the top. Sprinkle with 2 tablespoons sugar.

Step 4

Bake in the preheated oven until golden brown and a toothpick inserted in center comes out clean, 60 to 75 minutes.
