Prepare the strawberry sauce:
In a saucepan over medium heat, add the diced strawberries, sugar, and water.
Cook for a few minutes, stirring occasionally, until the strawberries start to break down and the mixture thickens slightly.
Remove from heat and let cool.
Prepare the cake:
Preheat the oven to 350°F (180°C) and line a 24 x 34 cm (9 x 13 inch) baking sheet with parchment paper.
In a large bowl, beat the cream cheese, eggs, 1 1⁄2 cups of sugar, coconut oil and vanilla extract until smooth.
Then, fold in the flour, salt, and baking powder with a spatula until fully incorporated.
Finally, add the milk and mix until the batter is smooth.
Pour the batter into the prepared baking sheet and evenly distribute the sliced strawberries on top. Sprinkle with 1⁄4 cup of sugar.
Bake for 30-35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Allow the cake to cool slightly before slicing.
Serve:
Cut into portions and serve with the strawberry sauce and a scoop of ice cream or whipped cream.
