Preparation Steps

• Begin by preheating your oven to 350°F (175°C). Grease a 9x13 inch baking pan and set aside.
• In a large bowl, mix the melted butter with both sugars until combined. Add the eggs one at a time, ensuring they are mixed in well after each addition.
• Sift together the flour, cocoa powder, and salt in a separate bowl. Gradually fold this dry mixture into the wet ingredients until just combined.
• Pour the brownie batter into the prepared baking pan, smoothing the top. Bake for 25 to 30 minutes, or until a toothpick inserted comes out mostly clean. Let cool completely.
• While the brownies cool, whip the heavy cream until it starts to thicken. Gradually add in the powdered sugar and vanilla, and continue whipping until soft peaks form.
• Gently fold the pureed strawberries into the whipped cream until well incorporated, being careful not to deflate the mixture.
• Spread the strawberry mousse evenly over the cooled brownies. Chill in the fridge for at least an hour before serving, so the mousse sets beautifully.
