Preheat the Oven: Start by preheating your oven to 180°C (350°F). Grease a mold that is approximately 22 cm in diameter.
Prepare the Strawberries: Wash the strawberries well, then remove the leaves and cut them in half. Set aside.
Sift Dry Ingredients: In a bowl, sift together the flour, salt, and baking powder.
Cream Butter and Sugar: In a separate bowl, using an electric mixer, beat the butter and sugar for about 3 minutes until it becomes creamy and light.
Mix Wet Ingredients: Reduce the mixer speed and add the egg and vanilla extract, beating until the mixture is homogenous.
Combine Ingredients: Gradually add the dry mixture into the wet, alternating with milk. Stir at low speed until just combined.
Assemble the Cake: Pour the batter into your prepared mold. Place the strawberries with their cut side down on top of the batter, pressing them slightly so they stay visible; sprinkle with the additional tablespoon of sugar.
Bake: Bake at 180°C for about 10 minutes, then lower the temperature to 160°C and continue baking for an additional 1 hour until golden brown.
