01 - Preheat oven to 350°F. Grease and line an 8x8-inch baking pan with parchment paper.
02 - In a large bowl, combine melted butter, granulated sugar, and strawberry puree. Whisk until thoroughly blended.
03 - Add eggs and vanilla extract to the mixture. Mix until fully smooth.
04 - In a separate bowl, whisk together all-purpose flour, baking powder, and salt.
05 - Gently fold the dry ingredients into the wet mixture until just combined. Avoid over-mixing.
06 - Pour batter into the prepared pan and smooth the surface with a spatula.
07 - Bake for 22 to 25 minutes, or until the edges are set and a toothpick inserted in the center yields a few moist crumbs.
08 - Let the baked brownies cool completely in the pan before glazing.
09 - In a bowl, whisk powdered sugar, strawberry puree, and lemon juice until smooth and pourable.
10 - Spread glaze evenly over cooled brownies. Allow glaze to set for 15 minutes, then cut into squares for serving.
