Preheat the oven to 350°F (175°C) and prepare a baking pan.

In a large mixing bowl, combine melted butter, brown sugar, and granulated sugar.

Add the eggs and vanilla extract to the sugar mixture, whisk until combined.

In another bowl, whisk together the flour, baking powder, and salt.

Gradually add the dry ingredients to the wet ingredients and mix until just combined.

Fold in the chopped strawberries, lemon zest, and lemon juice until evenly distributed.

Pour the batter into the prepared pan and spread it evenly.

Bake for 25-30 minutes, or until the edges are lightly golden and a toothpick inserted comes out with moist crumbs.

Let the blondies cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.

Once cooled, slice into squares and enjoy!
