Preheat your oven to 350°F (175°C). Grease and lightly flour a 9-inch cake pan.
In a medium bowl, whisk flour, baking powder, baking soda, and salt together.
In a large mixing bowl, cream butter and sugar until light and fluffy.
Beat in eggs one by one, then mix in vanilla extract.
Add lemon juice, zest, and buttermilk, stirring until smooth.
Gradually fold in the dry ingredients until just combined.
Gently stir in the chopped strawberries.
Transfer batter into the prepared pan and smooth the surface.
Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely before glazing.
To make the glaze, whisk powdered sugar, strawberry puree, and lemon juice until silky smooth.
Drizzle glaze generously over the cooled cake before serving.
