Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
Add Eggs: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
Mix Dry Ingredients: In a separate bowl, combine the flour and baking powder. Gradually add this dry mix to the butter mixture, alternating with milk. Stir in the vanilla extract until smooth.
Bake: Pour the batter into the prepared baking pan and smooth the top. Bake for 30–35 minutes or until a toothpick inserted into the center comes out clean.
Cool and Top: Once cooled, transfer the cake to a serving platter. Top with sliced strawberries and dust with powdered sugar, if desired.
