Step-by-Step Guide to Making the Mary Berry Inspired Chocolate Traybake Cake
Now, let’s get down to the nitty-gritty! Don’t worry, it’s really quite straightforward, and the results are so worth it. We’ll get this gorgeous cake into the oven in no time.
Step 1: First things first, get your oven preheated to 350°F (175°C). While that’s warming up, take your 13 x 9 inch traybake tin and give it a good grease and line it with baking paper. You want it nicely prepared so the cake doesn’t stick.
Step 2: In a nice big bowl, cream together your softened butter and caster sugar until it’s really pale and fluffy. You want to beat it well – this is where you build that lovely light texture.
Step 3: Now, add your eggs, but do it one at a time. Beat well after each egg goes in. This helps to make sure everything emulsifies properly and you don’t end up with a split mixture.
Step 4: Gently fold in about half of your self-raising flour, followed by the cocoa powder. Don’t overmix at this stage; just fold until it’s *almost* combined.
Step 5: Add the rest of the flour and stir everything together until you have a nice, smooth batter. Then, stir in your four tablespoons of milk until it’s all perfectly blended and looks lovely and glossy. It should be a lovely dropping consistency, like a thick batter.
Step 6: Spoon all that delicious batter into your prepared tin. Make sure it’s spread evenly to the edges so you get a nice, flat top – perfect for frosting!
Step 7: Pop it in the preheated oven and bake for about 30 to 35 minutes. You’ll know it’s ready when it springs back up lightly when you touch the top, and a skewer poked into the centre comes out clean. No gooey batter on the skewer!
Step 8: Once it’s baked, leave the cake to cool in the tin for about 10 minutes. This is important so it doesn’t break when you move it. Then, carefully turn it out onto a wire rack to cool completely. Patience is a virtue here!
Step 9: While the cake cools, let’s make that divine buttercream. Beat your softened butter with your sifted icing sugar and sifted cocoa powder. It’s crucial to sift them to avoid any lumps – nobody wants lumpy buttercream! Add your two tablespoons of milk and keep mixing until it’s super smooth and perfectly spreadable.
Step 10: Once the cake is completely cool – and I mean *totally* cool, otherwise the buttercream will melt – spread that gorgeous chocolate buttercream all over the top. Be generous!
Step 11: Finally, the fun part! Sprinkle on your chocolate sprinkles and white chocolate stars. It just makes it look so festive and cheerful. You could even add some extra chocolate shavings if you’re feeling really decadent, or perhaps some of these fabulous brownies if you have any leftover! Then, slice it into squares and enjoy your masterpiece.
Serving Suggestions for Your Chocolate Traybake Cake
This cake is utterly perfect on its own, but if you fancy jazzing it up a bit for a special occasion, here are a few ideas:
A Scoop of Vanilla Ice Cream: The classic for a reason! The cool, creamy vanilla is just divine with the rich chocolate. It’s like a hug in a bowl.
A Dollop of Fresh Cream: A simple swirl of softly whipped cream adds a lovely lightness that complements the cake beautifully.
Dusting of Cocoa Powder: For an extra sophisticated touch, a light dusting of extra cocoa powder over the top looks beautiful and intensifies that chocolatey punch. If you’re feeling really fancy, serve it alongside some creamy chocolate mousse!
Storing and Reheating Your Mary Berry Inspired Chocolate Traybake Cake
Now, if by some miracle you have any of this gorgeous Mary Berry Inspired Chocolate Traybake Cake left over, storing it is super simple. Just pop it into an airtight container. It’ll keep beautifully at room temperature for about 3-4 days, as long as it’s not too warm, of course. If it’s a really hot day, or you’ve made it further in advance, popping it in the fridge is a good idea, but remember to let it come back to room temperature for about 15-20 minutes before serving again. This really helps bring back that lovely soft texture. It’s also quite brilliant for meal prep; you can make it a day or two ahead of that party or occasion you’re planning!

Frequently Asked Questions About Mary Berry Inspired Chocolate Traybake Cake
Got a burning question about this delightful bake? I’m happy to help!
Can I make this Mary Berry Inspired Chocolate Traybake Cake dairy-free?
Oh, that’s a good question! While this recipe uses butter and milk in both the cake and the buttercream, you could certainly adapt it. For the cake, you could try using a dairy-free spread or a good quality margarine instead of butter, and a dairy-free milk alternative like oat or soy milk. For the buttercream, a dairy-free block butter alternative and a splash more milk alternative would work. It might change the texture slightly, but it should still be wonderfully chocolatey and delicious! You can also find loads of dairy-free ideas on sites like Pinterest.
What’s the secret to a really smooth buttercream?
The absolute magic trick, trust me, is *sifting*. Sifting your icing sugar and cocoa powder before you even start mixing is non-negotiable for a silky smooth buttercream! It gets rid of any little lumps that can make your frosting feel a bit grainy. Also, make sure your butter is properly softened but not melted – you want it creamy, not greasy. And don’t be afraid to beat it for a good few minutes; that’s what really helps to incorporate air and make it light and fluffy.
My cake looks a bit different to the picture, what could I have done wrong?
Don’t you worry about a thing! Sometimes cakes can look a little different, and that’s perfectly okay. Did your oven’s temperature run a little hot or cool? Sometimes they can be a bit temperamental! Or perhaps the baking paper wasn’t quite right? For a truly flawless top, make sure you spread the batter evenly right to the edges of the tin. If it baked a little unevenly, you can always snip off any very proud bits once it’s cooled before adding the buttercream! If it’s a flavour issue, perhaps try adding a touch more cocoa or a splash of coffee to the batter next time, like in my Mary Berry chocolate cake recipe, or really amp up the chocolate flavour with something like chocolate bread and butter pudding.
