Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper, leaving about a 2-inch overhang on each side for easy removal.

In a medium bowl, combine the all-purpose flour, granulated sugar, brown sugar, and salt (if using unsalted butter). Whisk together to eliminate any lumps.

Pour the melted salted butter and vanilla extract into the dry mixture. Stir until it begins to come together, then use your fingertips to create large crumbs.

Press about two-thirds of this crumb mixture evenly into the bottom of your prepared pan. Bake for 15-20 minutes or until lightly golden.

In another bowl, combine the chopped strawberries, granulated sugar, and all-purpose flour. Gently mix to coat the strawberries.

Once the crust has cooled slightly, spoon the strawberry mixture evenly over the crust.

Crumble the remaining one-third of the crust mixture over the strawberries.

Return the pan to the oven and bake for an additional 30-35 minutes, until the strawberry juices are bubbling and the topping is golden brown.

Remove from oven and allow to cool completely in the pan.

In a small bowl, whisk together the powdered sugar, cream, and vanilla extract until smooth. Drizzle this over the cooled bars.

Cut into 12 bars and enjoy!
