This Chocolate Raspberry Cake is a foolproof gluten-free buttermilk chocolate cake, sandwiched with a simple fresh raspberry swiss meringue buttercream.

My house is calm and silent. My toddler has slept in his own bed for the full night through in weeks and my husband’s alarm hasn’t yet shrieked for him to get up and get dressed. If my husband is still in bed no doubt the dog is snuggled up next to him, both as unwilling to start the day as the other. The cats have been fed, one of which is curled comfortably around this laptop, her belly in the air for attention and the other is still eating his breakfast. Yet I am awake, googling recipes and writing. Despite my eye constantly twitching from excessive exhaustion, my whole body feeling so big and heavy all it wants to do is sink within our brand new duvet cover and hug my pregnancy pillow close to me, I am up and awake. Why? Welcome to the third trimester of pregnancy.

I remember first time round people saying that the reason you can’t sleep in this final stage of pregnancy is nature’s way of getting you ready for all the sleepless nights ahead. I don’t need getting ready though, I’ve been having those for a couple of years already and I know the drill. What I need now is a head start on sleep to get ready for my return to night feeds but someone else has other ideas. This little baby I’m carrying is super active and wakes me up all night through twisting and squirming, except when I need to turn over which practically requires the assistance of a fork-lift truck or I need the loo for the twentieth time or my mouth is desert dry and can only be appeased by a gallon of water. Couple these restless nights with a day of full-time commitment to an extremely bouncy, chatty, effervescent and hungry toddler in potty-training then it’s safe to say my head is in a scramble and my body is like a lead balloon with the shape to match. How I long for the days of my first pregnancy when afternoons were given over to the Food Network and lazy naps on the sofa with a mountain of chocolate by my side.

In fact the only thing that hasn’t changed is the mountain of chocolate. It’s fuel to me at the moment. Luke asked if we wanted to do anything for Valentine’s Day this year and I scoffed at the thought of going out. Meals out are not fun at this stage. I can’t eat a lot and feel very uncomfortable sitting at a table for any length of time. Plus all I really want to eat is the pudding so the rest of the meal is somewhat wasted. The cinema also puts me off, I’m not sure I could be in those skinny seats for a great length of time in front of an Oscar bait film. I’d rather watch something that didn’t make me think or cry at the moment. Also they finish way past my bedtime.

So we’re celebrating Valentine’s this year with Netflix and Chocolate Raspberry Cake and I couldn’t be more happy. In fact, I don’t know why I’m blaming any of this lethargy on the pregnancy, really Netflix and chocolate cake are my go-to way to have a kicking time babies or no babies.

This Chocolate Raspberry Cake epitomises my favourite way of baking and eating cake. Simple and no-fuss. The gluten-free chocolate cake itself is one of my favourites that I return to time and time again. It’s moist and tangy from the buttermilk but incredibly chocolately thanks to cocoa powder and melted 70% dark chocolate.

If you haven’t made swiss meringue buttercream before then I urge you to splash out on the extra time it takes. It sounds complicated as there are a couple of extra steps involved compared to a buttercream made with just icing sugar and butter but if you’re a regular reader or a customer of my cake stall then you’ll be aware that swiss meringue buttercream is my cake covering of choice. It’s not too sweet, incredibly buttery and is so easy to work with. If pureeing the fresh raspberries seems a little too much effort on top of making the buttercream then you can always use raspberry powder which also gives a lovely zingy flavour and colour to your buttercream but I thought fresh raspberries suited the celebration of Valentine’s Day.

The piped roses on the top of the cake are a cinch I promise and if you are just making this cake for you and your Valentine now is the perfect time to practice as they two of you won’t care. All you need is a Wilton 1M nozzle, a piping bag and five extra minutes. Hold your piping bag straight up above the cake without angling it at all then squeeze the buttercream out in a circular motion starting from the centre. You want the swirls to be slightly on top of each other so they are nice and tight. However, they don’t have to be neat or perfect buttercream roses by any stretch as once they are all piped onto the cake then the effect is lovely no matter what your piping skills are like. If one rose goes wrong, just pipe another on top to cover it or use a palette knife to carefully lift it off the top of the cake and start again. Actually this is a much quicker cake to decorate than covering the whole affair in a smooth buttercream icing as you’re not faffing for ages getting the corners perfect.

So I may be tired, over-emotional, maybe a little complainy, definitely huge and always hungry but at least I have a big hefty Chocolate Raspberry Cake to devour this Valentine’s with my partner-in-crime.

Ingredients

• 125 g dark chocolate
• 150 g white rice flour
• 60 g oat flour
• 20 g tapioca flour
• 90 g cocoa powder
• 2 teaspoons espresso powder
• 1¾ teaspoons bicarbonate of soda
• 1 teaspoon salt
• 400 g buttermilk
• 160 g caster sugar
• 160 g soft light brown sugar
• 170 ml olive oil
• 3 eggs
• 1 teaspoon vanilla extract

Raspberry Swiss Meringue Buttercream

• 210 g egg whites around 7
• 350 g caster sugar
• 425 g unsalted butter at room temperature, cubed
• ¼ teaspoon of salt
• 1 teaspoon vanilla extract
• 300 g raspberries

Instructions

• Pre-heat oven to 160°C and line and grease 2 x 8 inch round cake tins.
• Melt the chocolate in a bain marie or a bowl set over a saucepan of simmering water, then set aside.
• In a large mixing bowl whisk together the flours, cocoa powder, espresso powder, bicarbonate of soda and salt until well mixed.
• In a separate bowl mix together the buttermilk, sugars, olive oil, eggs and vanilla then beat into the flour mixture.
• Finally mix in the melted chocolate until completely incorporated.
• Divide the mixture between the 2 cake tins and bake in the oven for 30-35 minutes until an inserted cocktail stick comes out clean.
• Turn out the cakes and cool on wire racks before covering with buttercream.

Raspberry Swiss Meringue Buttercream

• Heat the egg whites and caster sugar in a bain marie, or a bowl set over a saucepan of simmering water, stirring constantly until the sugar has dissolved and the temperature has reached 71°C.
• Remove the egg whites and sugar from the heat and pour into a stand mixer with a whisk attachment. Whisk until the meringue forms firm peaks.
• Change the attachment to a paddle attachment. On a low speed add the butter slowly cube by cube. When you have almost added all the butter the mixture will look curdled. Do not fret – this is supposed to happen and just means you are nearly done. Just continue to add all the butter. Once the butter is totally incorporated the buttercream will miraculously become a smooth velvety consistency.
• Make the raspberry puree by tipping all the raspberries into a blender and blending on high for a couple of minutes. Press the puree through a sieve to remove the seeds.
• Then add the raspberry puree to the buttercream along with the vanilla extract and salt. At first the buttercream will look curdled again but just mix for a couple of minutes until it returns to its smooth state.

Assembly

• Spread the buttercream in an even layer over one of the chocolate cakes, then place the second chocolate cake on top.
• Smooth out the buttercream squidging from the centre of the cakes with a palette knife to create the naked effect.
• Pipe buttercream roses on top of the cake until completely covered.
• You can keep the cake in the fridge until needed but do serve the cake at room temperature.

SHOP THE RECIPE

The cake tins I always use are these PME Anodised Aluminium Round Cake Pan 8 x 4-Inch Deep which are wonderful as they have completely straight sides so your layer cakes will be beautifully neat, the anodised aluminium means the heat disperses evenly throughout the cake without cooking the sides too quickly, which some darker cake tins do. The cakes slip out of the tins easily and they come in all the sizes you would need, although typically I use the 8 inch tins.

For checking the temperature of your egg white sugar syrup when making your swiss meringue buttercream don’t be without a Classic SuperFast Thermapen 3 professional food thermometer in grey colour It gives quick and accurate temperature readings meaning you can don’t have to guess at any temperatures when making candy, caramel or fancy buttercreams. I use mine all the time.

The piping tip I used in this recipe is the Wilton Number 1M Carded Open Star Tip which can so many different kinds of piping patterns and is one of the most useful piping tips to have handy.

I find these huge disposable piping bags are the most robust ones you can buy, I do get a huge pack of them as the worst thing is to get ready to ice your cake and discover you don’t have any piping bags left. I use disposable as I bake a lot of cakes and find washing up the re-usable piping bags takes a lot of time and I can never get them totally clean. I use these piping bags for everything from cupcakes to drizzling melted chocolate to piping a straight level of buttercream evenly over a whole layer cake. This 1 Roll of Savoy Disposable Piping Bags – 100 21 Bags by Cn-Ice is an absolutely invaluable piece of kit in my baking.
