Preheat the oven to 350°F (175°C). Grease and flour a 9x13 inch baking dish. In a bowl, whisk together flour, baking powder, and salt. In another bowl, beat the butter and sugar until light and fluffy. Add eggs one at a time, mixing well after each addition, then stir in vanilla. Gradually add the flour mixture to the butter mixture, mixing until just combined. Pour the batter into the prepared baking dish and bake for 25-30 minutes, or until a toothpick inserted comes out clean.

Prepare the Milk Mixture

In a separate bowl, combine sweetened condensed milk, evaporated milk, and whole milk. Once the cake is baked and still warm, poke holes all over the cake with a fork or skewer. Pour the milk mixture evenly over the cake, allowing it to soak in. Let the cake cool completely.

Make the Whipped Cream

In a medium bowl, whip the heavy cream until soft peaks form. Gently fold in the pureed strawberries to create a strawberry crema.

Assemble the Cake

Once the cake has cooled and soaked up the milk, spread the strawberry crema evenly over the top. Garnish with dark chocolate shavings.

Serve

Slice the cake and serve chilled. Enjoy your delicious Tres Leches with strawberry crema and dark chocolate!
