Preheat the oven to 350°F (175°C). Grease and flour a 9-inch cake pan.
In a large mixing bowl, combine flour, sugar, baking powder, baking soda, and salt. Whisk together until evenly distributed.
1 cup buttermilk, 1.5 cups granulated sugar, 1 teaspoon baking powder, 0.5 teaspoon baking soda, 0.5 teaspoon salt
In a separate bowl, whisk together buttermilk, vegetable oil, eggs, vanilla extract, and pickle juice until smooth and well combined.
1 cup buttermilk, 0.5 cup vegetable oil, 3 large eggs, 1 teaspoon vanilla extract, 2 tablespoons pickle juice
Pour the wet mixture into the dry ingredients, then gently fold until just incorporated. Do not overmix.
Fold in chopped strawberries and lemon zest into the batter, ensuring even distribution and visible fruit pieces.
1 cup fresh strawberries, 2 teaspoons lemon zest
Pour the batter into the prepared cake pan, smoothing the top with a spatula. Bake for 35 minutes or until a toothpick inserted into the center comes out clean.
Remove the cake from the oven and allow it to cool in the pan for 10 minutes. Then, transfer to a wire rack and cool completely.
