Chocolate Milk Cake is my favourite version of Mexican Tres Leches Cake. In this recipe, a light chocolate cake is bathed in a chocolate milk syrup.
Preheat the oven to GM4/180 C and butter a9 x 13 oven trayor casserole dish leaving a 1 cm gap around the edges, do not butter the sides. Adjust oven rack to middle of oven.
Combine flour, baking powder and salt in a large bowl.
Seperate 5 eggs - Put the egg & yolks in 2 seperate bowls.
Beat the egg whites on high until soft peaks form. This takes around a minute. With the machine still running, add 50g/1/4 cup caster sugar and beat on high until egg whites are stiff (1 - 2 minutes).
Stir in 80g or 1/3 cup milk and Lime Juice into the yolk mixture.
Gently add the flour mixture to the egg yolk mixture. Then carefully fold in the egg whites. This takes some gentle persuasion but don't be tempted to rush it or be too heavy handed.
Pour into tin/dish and bake for 25 – 30 minutes.
Make Milk mixture by combining evaporated milk, condensed milk, double cream, Lime and Cocoa powder in a bowl and whisk together.
Once the cake has cooled, pierce all over with a fork and drizzle in the milk mixture. Leave to stand for 30 minutes.
In a large bowl combine double cream and sugar and whip on high until thick. This takes around 3 - 5 minutes. Keep a very close eye on it though.
Spread cream over the cake with a spatula then drizzle with melted chocolate and add Lime zest.
Add all the ingredients for the syrup in a bowl and whisk together.
Cut cake into pieces and add to bowls. Drizzle syrup around the cake and serve.
This is one of those rare cakes that really benefits from fridge time. Store covered in the fridge for a few hours or up to 3 days.
It can but without the syrup and decoration. Make just the cake can be made ahead of time. Allow to cool and then cover with 2 layers of cling film before freezing for up to 2 months.
To serve, thaw in the fridge over night and add the syrup and decoration the following day.
