Black Brushstroke Cake for Halloween

Black Brushstroke Cake for Halloween

Welcome to the dark side. But don’t worry, there’s cake! Black brushstroke cake, to be exact. Earlier this year, in my monthly baking column for Food24, I wrote about how darkness was going to descend on baking and treats were going to go gothic. Sometimes trends are silly and sometimes they can be fun – especially when they tie in with a celebration. And while I definitely don’t celebrate Halloween, it does give us bakers a fantastic excuse to get super creative. When the folks over at Food & Home Entertaining Magazine asked me to create a gothic food feature for their October issue, it was like putting me in a candy store! This Black Brushstroke Cake was the result and it is one heck of a showstopper – a jet-black velvet cake is sandwiched together with burnt vanilla buttercream and decorated with black chocolate brushstrokes. What is burnt vanilla, I hear you ask? Well, by baking the vanilla, the sugars in the bean caramelise giving it a more intense, toasty flavour.

If you haven’t yet tried the chocolate brushstrokes – check out my tutorial here – it’s a lot easier than it looks!

BLACK BRUSHSTROKE CAKE WITH BURNT VANILLA FROSTING 

Makes 1 x 20cm cake, serves 6-8

 

240g cake flour

490g Natura Sugars Golden Caster Sugar

100g The Kate Tin Cocoa Powder

10ml (2 tsp) bicarbonate of soda

5ml (1 tsp) baking powder

large pinch salt

2 large eggs

180ml (¾ cup) strong coffee, cooled

320g buttermilk

125ml (½ cup) canola oil

black gel food colouring

 

BURNT VANILLA FROSTING

1 vanilla pod, halved

125g butter, softened

60g The Kate Tin Cocoa Powder, sifted

300g Natura Sugars Demerara Icing Sugar, sifted

45 – 60ml (3 – 4 tbsp) milk

black gel food colouring

 

BLACK BRUSHSTROKES

black powder food colouring

100g The Kate Tin Dark Baking Chocolate, melted

 

For the cake, preheat the oven to 180˚C. Grease and line 3 cake tins (20cm diameter) with baking paper.

In a large bowl, sift together the dry ingredients and make a well in the centre. In a separate bowl, whisk together the eggs, coffee, buttermilk, canola oil and a few drops black gel food colouring.

Pour the wet ingredients into the dry ingredients and whisk until just combined. Divide the batter among the tins and bake in the preheated oven, 30 – 40 minutes or until springy to the touch and a skewer inserted in the centres of the cakes comes out clean. Allow to cool in the tins, 5 minutes, before turning out onto a wire cooling rack to cool down completely.

To make the icing, place the vanilla pod on a baking sheet in the oven and roast, 5 minutes, until fragrant. Scrape the seeds from the pod and discard the pod. Place the seeds in a blender or pestle and mortar and blitz or pound to form a fine powder. Cream the butter until light and fluffy, then add the vanilla powder, 60g cocoa, the icing sugar, milk and enough gel food colouring to make a black icing. Beat until smooth and completely combined.

For the brushstrokes, line a baking sheet with baking paper. Mix the powder colouring into the melted baking chocolate. Drop a teaspoonful coloured chocolate onto the baking sheet, then use the back of a spoon to smear the chocolate like a brushstroke over the baking sheet. Repeat until all of the chocolate has been used up. Allow to set before peeling off the brushstrokes.

Assemble the cake by layering the sponges with burnt vanilla buttercream icing between each layer. Cover the entire cake in icing and smooth out with a palette knife. Using dollops icing, stick the brushstrokes on the front of the cake to decorate.

 

Brushstroke Cake | How To Make It

Brushstroke Cake | How To Make It

The brushstroke cake is one of my favourite trends! Why? Because literally anyone can do it.

Brushstroke cakes have taken over our instagram feeds and I couldn’t be happier. Unlike some of the other cake decorating trends, this one is easy to nail. First we wanted them draped in fondant (ugh). Then we wanted them naked (ugh again). Then came the drip cakes (still kinda love this one), hypnotic mirror-glazes (pretty but tricky) and the unicorn obsession (please no) that we’re all still trying to mentally recover from. If you’re sick of unicorns, then I’m happy to tell you that they’ll be going back to the magical place they came from.

STEP 1: Make your favourite cake recipe (this is mine), frost it all over then refrigerate.

STEP 2: Make the brushstrokes – melt about 200g of chopped good-quality white chocolate (you’re going to eat it remember, so get the good stuff)

STEP 3: Tint it your desired colours using POWDER FOOD COLOURING. This is really important – the liquid/gel stuff will just cease your chocolate. You can find the powders at any baking shop. And don’t worry, because afterwards you can use the powders to colour frostings, batters, etc.

STEP 4: Drop a teaspoonful of the chocolate onto a silicone baking mat or baking paper, then use the back of the spoon to smear it outwards. Don’t make it too thin or the strokes will crack later. I’ve seen many people using a pastry brush to brush the chocolate but I find it makes them way too thin and they break easily. Allow them to set completely then remove them with a palette knife or sharp knife.

STEP 5: On your already-frosted cake, work from the back and gently press the chocolate brushstrokes into the buttercream. If they don’t stick, simply stick a knife into the cake to create a slot for the chocolate brushstroke to fit into. Continue layering to the front, using blobs of frosting to stick them onto the cake. Refrigerate until ready to serve! Brushstroke cake done -voila!

TIP If you want to add some bling, dust the brushstrokes in gold or metallic dust once they’re set – it would look spectacular on a chocolate cake!
