Preheat the oven to 350°F (175°C) and grease and flour your cake pan.
Whisk together the all-purpose flour, granulated sugar, baking powder, and salt in a mixing bowl.
Add the softened unsalted butter, large eggs, milk, and vanilla extract to the dry ingredients and mix until smooth and creamy.
Pour the batter into the prepared cake pan and spread it evenly. Bake for 25 minutes or until a toothpick inserted in the center comes out clean.
Cool the cake completely before frosting.
Whip the chilled heavy cream in a mixing bowl until soft peaks form.
Add the powdered sugar and vanilla extract to the whipped cream and continue whipping until stiff peaks form.
Spread a layer of frosting generously on top of your cooled cake.
Top with mixed fresh fruits and edible flowers for decoration.
Slice and serve your Monet cake to enjoy!
