Preheat your oven to 350°F (175°C) and grease a 9x9-inch baking pan.

In a large mixing bowl, cream together room-temperature unsalted butter and sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition.

In a separate bowl, sift together the flour, baking powder, and salt. Gradually add to the wet ingredients while mixing on low speed.

Spread the batter evenly into the prepared baking pan and bake for 30-35 minutes until golden.

Remove from the oven and let cool completely in the pan on a wire rack.

While the bars cool, wash and slice your strawberries, patting them dry if juicy.

Once cooled, slice the bars into squares and top with strawberries and whipped cream if desired.
