Start by preheating an oven to 180c (350f) and prepare a 9×13 baking pan with parchment paper.
Into a medium mixing bowl, add the flour, baking powder, and baking soda. Mix with a whisk until combined.
Into a big mixing bowl, add the eggs and sugar and mix with an electric hand mixer until the mixture is fluffy and light in color.
Add the vanilla extract, strawberry puree, vegetable oil, chopped strawberries, and strawberry jam. Mix until combined.
Then add the buttermilk and mix with the hand mixer until combined.
Add the dry ingredient, and mix until just combined. Don’t overmix!
Pour the batter into the prepared baking pan and bake the cake in a 180c (350f) preheated oven for about 30 minutes or until a skewer inserted into the cake comes out clean. let the cake cool to room temperature.
Into a big mixing bowl, add the cold heavy cream, powder sugar, and mix with an electric hand mixer until stiff peaks form.
Add the softened cream cheese and the strawberry puree and mix until just combined. Don’t overmix.
Top the cake with the strawberry whipped cream and smooth it out. We made a wave pattern with a spatula.
Slice fresh strawberries in half and top the whipped cream with more strawberries. Serve and enjoy!
