Preheat your oven to 350°F (175°C) and lightly grease a pizza pan or line a baking tray with parchment paper.
In a bowl, mix flour, baking powder, and salt. Set aside.
In another bowl, beat butter and sugar until smooth. Add lemon zest, lemon extract, and egg, mixing until combined.
Gradually add the dry ingredients and mix until a soft dough forms.
Press the dough evenly into a 10-inch circle on your prepared pan.
Bake for 15–18 minutes or until lightly golden. Let it cool completely.
For the topping, beat cream cheese, powdered sugar, vanilla, and salt until smooth.
Slowly add heavy cream while mixing, then beat on high until light and fluffy.
Spread the topping evenly over the cooled crust.
Arrange strawberries and blueberries on top in your desired pattern.
Slice and serve fresh for best results.
