Preheat the oven to 350°F (175°C). Grease a 9-inch baking pan and set aside. In a small bowl, prepare the sliced strawberries and set aside.
1 cup fresh strawberries
In a large mixing bowl, whisk together the flour, sugar, and lemon zest until combined. Add the melted butter, eggs, lemon extract, and milk, then stir until the batter is smooth and just combined. Gently fold in the sliced strawberries until evenly distributed.
1 cup fresh strawberries
Pour the batter into the prepared baking pan, spreading evenly with a spatula. Place in the preheated oven and bake for about 30 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack and allow to cool completely until the surface feels firm and slightly shiny.
Slice the cake and serve, revealing a moist crumb dotted with strawberries and a hint of lemon aroma. The surface should be lightly browned with visible bits of fresh berries.
