Puree 400 g of quartered strawberries using a food processor or blender until smooth. Transfer the puree (approximately 375 ml) to a medium saucepan. Simmer over medium heat, stirring frequently, until reduced to 180 ml, about 20–25 minutes. Pour into a measuring cup, cool to room temperature.

Preheat oven to 176°C. Line the bases of three 20 cm round cake tins with parchment paper and lightly grease the sides.

In a large bowl, whisk together the cooled strawberry reduction, sour cream, milk, eggs, and vanilla extract. Reserve 250 ml of this mixture in a separate bowl or jug; retain remaining 375 ml in the original bowl.

In a stand mixer bowl, combine flour, sugar, baking powder, baking soda, and salt.

With the mixer on low speed, add room temperature butter in tablespoon-sized pieces. Allow each piece to incorporate before adding the next, until the mixture resembles wet sand.

Add the larger portion (375 ml) of the strawberry-egg mixture to the dry mixture. Mix on low speed until incorporated, then scrape the sides. Increase speed to medium-high and beat for 45–60 seconds until light and fluffy. Scrape down the bowl.

With mixer on low, stream in the reserved 250 ml of liquid until fully incorporated. Scrape down the bowl, then mix on medium-high for 10–15 seconds until the batter is cohesive. Add optional pink food colouring, blending until even.

Divide batter evenly among prepared pans. Bake for 24–26 minutes or until a toothpick inserted in the centre comes out with a few moist crumbs. Remove tins from the oven, cool for 2–3 minutes, then carefully transfer cakes to a rack to cool completely.

Process freeze-dried strawberries in a food processor until finely ground. Yields slightly over 120 ml strawberry powder. Set aside.

In a mixer bowl, cream together cream cheese and butter until smooth. Gradually incorporate half of the icing sugar and vanilla. Mix in remaining icing sugar and the prepared strawberry powder. Add a pinch of salt to taste, mixing until fully combined and smooth.

Carefully level cooled cake layers with a large serrated knife. Place one layer on a serving plate. Spread with approximately 240 ml frosting. Evenly scatter half of the chopped strawberries over frosting and gently press in.

Add the second cake layer. Cover with another 240 ml frosting and the remaining chopped strawberries. Top with final cake layer.

Frost the cake's exterior and top with remaining frosting. Use a piping bag with desired tips to apply decorative borders on the top and bottom edge. Garnish with additional strawberries as desired. Chill until ready to serve.
