Condensed Milk Chocolate Sheet Cake

If you like chocolate desserts then you are definitely going to love this recipe. A soft chocolate sponge cake topped with a condensed milk chocolate frosting, I bet you are loving it already right?

They are quick easy and perfect for bake sales, parties or just for afternoon tea.

Portable too, these treats can be baked sliced and served from the same tray as well.

With this Condensed Milk Chocolate Sheet Cake, it is no different.

Perfect for parties and feeding a crowd (though you might just want to save a couple of pieces for yourself first)

The entire can of condensed milk is used in this cake, with the majority of it being used in the frosting

Making the cake

• Start by greasing and lining a 9 x 13 inch / 23 x 33 cm cake pan with parchment/baking paper.
• Melt the butter and then stir in the cocoa powder and water with 1 teaspoon of coffee dissolved in it. Coffee enhances the taste of the chocolate, and there is no taste of the coffee in the cake at all.
• However, if you do not want to use coffee, then just leave it out and add the plain water instead. Bring this mixture to a boil, then remove from the heat.
• In another bowl, combine the flour, baking soda ( bicarbonate of soda) sugar, and salt.
• Beat the cocoa mixture into the flour mixture, then stir in just ⅓ cup (102g) of the condensed milk, vanilla extract and buttermilk*. Whisk until combined.

• Pour the cake mixture into the prepared pan.
• Bake in a preheated oven of 350°F/ 170°C for 15 to 20 minutes, until the cake springs back when lightly touched. Remove from the oven and allow the cake to cool in the pan.

Buttermilk substitute

*If you do not have buttermilk, then substitute it by adding 2 teaspoons of lemon juice or vinegar to ½ cup (125ml) full fat / full cream milk. Let it stand for 5 minutes before using it in place of the buttermilk.

Chocolate frosting

• In a small pan, melt the butter and stir in the cocoa powder and ¾ cup ( 230g) condensed milk.
• Stir in the powdered sugar/icing sugar and mix well.
• Pour the frosting over the cake and allow it to set before slicing.

Leftover frosting? Delicious ideas

If you find that you have extra frosting, don't throw it away. This frosting makes a great chocolate sauce for your ice cream. Store any extra frosting in an airtight container and use it over ice cream or in a milkshake.
