Prepare a 9x9 baking pan (square or springform pan) by greasing the inside with butter or a flour baking spray, or lining with parchment paper. Set aside.
In a large mixing bowl whisk together the dry ingredients: flour baking powder, baking soda and salt. Set aside.2 1/2 cups all purpose flour, 1 1/2 tsp baking powder, 1/2 tsp baking soda, 1/4 tsp salt
In a separate bowl of a stand mixer, cream together the butter and sugar until smooth and creamy (I just use the paddle attachment).1/2 cup butter, 1 cup sugar
Add the eggs to the butter mixture, one at a time, mixing well.2 large eggs
Add in the vanilla and mix well.1 tsp vanilla
To the butter mix add 1/3 of the flour mixture, then 1/2 of the buttermilk. Repeat until everything is combined. Make sure to scrape the sides of the bowl with a rubber spatula as you go.1 cup buttermilk
In a separate bowl, gently toss the chopped strawberries with 1 tsp of flour. This will help to keep the berries from staining the cake batter.2 cups chopped fresh strawberries, 1 tsp all purpose flour
Use a wooden spoon to gently stir the chopped strawberries into the cake batter. Don’t use a mixer or the batter will become pink.
Transfer the cake batter into the prepared pan. Smooth it down (it's a sticky batter).
Sprinkle the top of the cake with 2 tbsp sugar.
Bake the cake for 60 minutes, or until a toothpick inserted into the centre of the cake comes out clean. The top of the cake should be light golden brown. If you're using a springform pan, remove the sides (I leave the bottom on). Let the cake cool on a wire rack.
