    • Lazy Cake (Chocolate Biscuit Cake)

    No-bake fridge Chocolate Biscuit Cake is known as the favorite cake of the Royal family, especially the late Her Royal Majesty Queen Elizabeth and Prince William.

    It is super easy to create this simple yet impressive Lazy Cake with a few ingredients such as tea biscuits, good-quality chocolate, butter, cacao powder, and milk.

    If you love rich and decadent chocolate desserts, check out my other recipes such as Moist Chocolate Cream Cake, Chocolate Nutella Babka Bread, Chocolate Strawberry Tartlets, and Chocolate Eclair Cake with Choux Pastry.

    What is Lazy Cake (Chocolate Biscuit Cake)?

    Lazy Cake is an indulgent and rich no-bake Chocolate Biscuit Cake that requires minimal effort and ingredients, hence the name.

    This simple dessert is made by mixing crushed tea biscuits with some sort of chocolate sauce.

    The recipe might vary depending on the region, some might contain sweetened condensed milk and others eggs. 

    Lazy Cake is a very popular dessert around the world and is known by different names in different countries.

    In Turkey, we call it Mozaik Pasta (Mosaic Cake) and it usually requires eggs. In Italy, it is known as a Chocolate Salami, and in Greece as a Kormos or Mosaico.

    • It is a crowd-pleaser, this recipe will give you 12 generous slices!

    • You can make it ahead, and keep it in the fridge for up to a week, or in the freezer for up to 3 months.

    Ingredients You'll Need

    Please scroll down to the recipe card below for the full ingredients list with measurements, complete recipe method, recipe notes, and nutritional information

    Labelled picture of ingredients for lazy cake - chocolate biscuit cake
    • Biscuits - I use Petit Beurre biscuits as they are the most popular ones that we use in Turkey for making Mozaik Pasta (or Mosaic Cake). However, you can use whatever is available for you, such as digestive biscuits or graham crackers.
    • Chocolate - Here in this Chocolate Biscuit Cake recipe, chocolate is the star of the show so it is important to choose a top-quality one you can afford. I use Lindt 70% dark chocolate but Valrhona chocolates are also quite popular.
    • Butter - I melt the butter in the microwave before adding it to milk to make things quicker. However, you can melt the butter together with the milk. Both salted and unsalted butter works fine with this recipe.
    • Milk - Milk provides the moisture necessary to help the sugar dissolve, and also thin out the batter making it much easier to mix with the biscuits. You can substitute it with orange juice.
    • Cacao Powder - Same as when I am making no-bake dessert Classic Italian Tiramisu, I prefer using good quality unsweetened cocoa powder for a rich & bitter chocolate taste.
    • Walnuts - They add extra crunch and flavor to Lazy Cake. Lightly toast them in the oven and crush them before adding them to the biscuits. You can substitute walnuts with pecan nuts, hazelnuts, or pistachio nuts.
    • Icing Sugar - Because it melts quicker! You can use caster sugar if you prefer.

    How to Make Lazy Cake?

    Although making Lazy Cake (Chocolate Biscuit Cake) is very easy, you need to follow a few simple steps to achieve the best results:

    Preparing the Chocolate Sauce

    Melt the butter in a microwave, and place it in a saucepan along with the milk, cacao powder, and icing sugar. 

    milk, butter, sugar and cacao powder are placed in a pan

    Give them a good stir, place the pan on medium-low heat, and bring it to a boil.

    Remove the pan from the heat and add the chocolate pieces. 

    Chocolate pieces are added to hot mixture of milk, sugar, butter and cacao powder

    When the chocolate pieces melt, give the mixture a good stir until the sauce is nice and shiny, and all the chocolate is incorporated.

    Chocolate pieces are melted and incorporated with milk mixture

    Let the chocolate sauce cool down for 10 minutes while preparing the biscuits and lining the loaf pan with a cling film or parchment paper.

    Preparing the Cake

    Line a 23 cm (9") loaf pan with cling film or parchment paper, leaving an overhang to cover the cake later.

    This step is necessary to avoid the cake from sticking to the pan when you flip it.

    Break the biscuits into chunky pieces in a large bowl.

    Chop or crush the walnuts (lightly toasted in a 160° C - 320° F preheated oven for 10 minutes), and add them to the biscuits.

    Pour in the chocolate sauce and give them a gentle stir, making sure all is combined.

    Transfer the mixture to the loaf pan and press it gently, making sure that the biscuits are firmly packed without any gaps.

    Cover the top of the cake with overhanging cling film (or parchment paper), and place it in a freezer.

    Freeze the cake for a minimum of 3 hours, remove the cling film and transfer it to a serving plate. 

    Alternatively, if you're not serving it on the same day, you can place the cake in the fridge overnight.
