    Although so easy to make, this chocolate cake traybake with frosting is really a treat! I mean, think about it! Double chocolate: in the cake and on top of it! You will just love it!

    This recipe makes quite a large batch, but trust me, no piece was left by the end of the day. We had some guests, and I had actually baked two cakes for the occasion... I could not believe that all of this tray bake was gone so fast.

    But then, it is chocolate... And hazelnuts! And an amazing frosting to make things complete!

    I love cake tray bakes. Wonderful cakes like this Hazelnut Banana Cake, our favorite Apple Cake with Stewed Apples, or this Stewed Apple Desert.

    • Chocolate Cake Traybake

    Recipe ingredients

    Chocolate for the cake and the frosting: As always recommended, when using chocolate in such large quantities, make sure you buy good quality. In this case, you will need the dark sort with about 70% cocoa; a bit more or less is OK.

    • Don't use milk chocolate or anything less than 60% cocoa to make the cake.
    • For the frosting, you will need semi-sweet chocolate.

    Spices: I use a little ground cardamom to flavor the batter. I love it, but if you don't like it or don't have it, you can leave it out or replace it with cinnamon. Here are more cakes using cardamom: Brown Sugar Cake and Ikea Cinnamon Rolls.

    Other ingredients are ground hazelnuts, unsalted butter, eggs, flour, and heavy/double cream.

    See the recipe card for full information on ingredients and quantities.

     How to make a chocolate cake traybake?

    Chocolate cake step-by-step

    • Step #1: Mix dry ingredients: flour, hazelnuts, grated chocolate, cardamom (if using), and salt. Set aside.
    • Step #2: In another large bowl, beat the eggs, sugar, and soft butter together until nice and fluffy.
    • Step #3: Add the dried ingredients and incorporate them.
    • Step #4: Pour this mixture onto a baking tray lined with baking paper and bake in a preheated oven for 25 minutes.
    • Step #5: Leave to rest for about 15 minutes. Cut it into squares, leaving the squares on the tray. Let the cake cool completely on the tray.

    Chocolate glaze step-by-step

    • Step #1: Bring the heavy cream to a light simmer. Remove and stir in the chopped semi-sweet chocolate, sugar, and cubed butter. Stir well until melted and glossy.
    • Step #2: Carefully pour the glaze all over the chocolate tray bake, and let it set for about an hour or longer. The glaze will not become completely solid; it will set but remain soft.
    • Step #3: Decorate each square with the decoration of your choice.

    How to store?

    Keep the chocolate tray bake squares in an airtight container in a cool place (not necessarily refrigerated; a cold cellar would do). The cake be okay for at least one week.

    The glaze can be refrigerated for 3 -4 days and can be frozen for 1-2 months.

    If you have some leftover glaze, you can pour it on top of ice cream or waffles, for instance, as a kind of sauce.
