I’d love to know who was baking one day and thought to themselves ‘I know what would perfect this recipe, a generous dose of red food coloring!’

Such a bizarre missing ingredient but it somehow manages to turn a humble chocolate cake into something pretty amazing.

Why this recipe

  1. Next level deliciousness - A traditional red velvet cake apparently has cream cheese buttercream but this recipe uses an American-style buttercream ‘frosting.’ It takes it to a whole new level.
  2. Rich, moist & velvety - this cake has the perfect soft, tender crumb with just the right balance of chocolatey goodness & a little tang.
  3. Perfect for any occasion - whether it's a Birthday, anniversary or just a 'treat yourself' day this red velvet cake is a show stopper.
  4. No special skills required

If you can resist going back for seconds, you’re much stronger-willed than me.

​Cake Ingredients

To make this red velvet cake you will need: 

  • Water - preferably filtered
  • Butter - pure butter not margarine (most recipes say to use unsalted butter but I usually use salted)
  • Cocoa
  • Plain flour - also known as all-purpose flour (or cake flour can be used). 
  • Caster sugar
  • Baking soda
  • Salt
  • Eggs
  • Buttermilk (or use milk soured with a little lemon juice)
  • Vanilla - Here's how to make your own vanilla extract.
  • Red food colouring - if you can get your hands on gel colouring it's the best for this.

Cake Instructions

The method is a little bit different to a classic red velvet cake apparently.

It a different method to any cake I've made.

Actually in the magazine, these are called brownies but I don’t see one part of them that even remotely resembles a brownie (or is that cake in America?) so I called it cake.

  1. You start by melting the butter in a small saucepan then add the water and cocoa and stir it all together until it’s smooth.
  2. Take the saucepan off the heat. 
  3. Put the flour, sugar, baking soda and salt (the remaining dry ingredients) in the bowl of a stand mixer with the paddle attachment in and then pour the chocolatey mixture over the flour mixture.
  4. Mix it on low speed to begin with (not LOW if you don’t want chocolate from one end of the kitchen to the other) and then increase the speed to high and beat until everything is very well mixed together.
  5. Add the red colouring, egg, buttermilk (or soured milk like I used) and vanilla then start on low speed again and increase it to high to beat everything well.
  6. The batter is really really runny at this stage. I actually didn’t think there was even a slither of hope that it would bake into something resembling a cake but I kept on going.
  7. Use a rubber spatula to scrape the batter into a prepared tin. It’s best not to use a spring-form tin or it might drip all over your oven.
  8. Once you’ve licked the bowl, pop the tin into the oven at 160C for 25-30 minute or until a cake tester comes out clean.
  9. Once it’s cooked, leave it to cool completely in the tin.

If you watch Two Broke Girls you might have seen the ‘buttercream is a b-i-t-c-h’ episode.

They have a little cupcake business and get an order for 60 cupcakes with buttercream frosting which they have to transport on the subway.

I’ve always thought buttercream was just butter beaten with icing sugar and a little milk or water the thin it so I wasn’t quite sure what the big deal was with transporting cupcake topped with it across New York in summer.

Actual American buttercream is completely different to what I thought.

It’s light and fluffy and not too sweet and there’s not a bit of icing sugar (or powdered sugar) in it.

The downside to the buttery goodness is that it’s very temperamental and easily splits resulting in a melted, ugly mess.

I think it’s best to serve buttercream icing-topped items straight away.

American buttercream is a delicious, fluffy but not-too-sweet frosting quite different to the buttercream we’re used to here in Australia. 

Icing Ingredients

To make American buttercream icing for this red velvet cake you will need: 

  • Caster sugar (also known as superfine sugar)
  • Milk - I always like to use full-fat milk (also called whole milk) in baking for more flavour. 
  • Plain flour - also known as all-purpose flour
  • Salt
  • Vanilla extract
  • Butter - the butter is really important. Make sure you use the real stuff that comes wrapped in foil not something in a tub with added ingredients. 

Icing Instructions

To make it, heat the sugar, milk, flour and salt in a small saucepan, whisking constantly until it starts to bubble and thicken.

It probably takes about 5 minutes.

Once it starts to thicken, reduce the temperature and whisk it for one more minute then take it off the heat and add the vanilla.

Set it aside to cool to room temperature.

Don’t be tempted to move on to the next step before it cools or your icing won’t be too pretty.

Once it is cool transfer the mixture into the bowl of an electric mixer then a little at a time, add the softened butter, beating until the icing is thick and smooth.

It might start to curdle a little but keep on beating – it’ll smooth out eventually.

When your icing is ready, spread it into the top of the cake (an offset spatula will make the job easy) and call your friends.

The creamy frosting can be spread down the sides of the cake but I think it looks better piled on top.

You don’t want to be alone with this once you’ve got a taste for it let me tell you.

It looks like there’s a lot of icing for such a small piece of cake but believe me, it’s just right. It's also best cut in individual slices this big to slow you down. 

Being red and white, it’s the perfect cake for your Christmas dessert table (oh sorry is it just me who has an entire table dedicated to dessert?).

​It would also make a perfect Valentine's Day dessert.

Cake FAQs

What's the best cocoa to use for red velvet cake?

Natural cocoa powder is the best cocoa to use for red velvet cake as it has the most authentic chocolate flavour. 
The other reason is to lower the pH of the cake. This is getting a little technical but to get a true red colour, we want to have a more acidic cake. 
It's why we use baking soda instead of baking powder and buttermilk instead of regular milk. 
If you use a dutch processed cocoa or cacao powder then I would recommend adding a teaspoon of white vinegar to the recipe so the red colour is vibrant. 

What type of red food colouring should you use for red velvet cake? 

Red food colouring comes in 3 different types - liquid, gel and powdered. 
This recipe uses liquid food colouring. 
If using gel food coloring (which probably gives it the best red colour), start with ⅓ of the amount and add more to get the desired colour as in the photos. 
Unfortunately, the natural food colourings would probably not be strong enough for this recipe but if I were to try one, I'd go with beetroot. 

Can you use this recipe to make red velvet cupcakes?

Absolutely you can. 
It should make about 12 regular size cupcakes. 
Line a cupcake tray with wrappers then divide the cake batter between them. 
The bake time will be less than a whole cake. 
Bake them at the same temperature for 15-20 minutes or until a cake tester comes out clean. 
Take them out of the tin to cool on a wire rack.

Enjoy!

    This cake is really delicious. I made it last night. Even though you suggested not making it in a spring based tin, I did as I want to try a layered cake this weekend. The cake took about 1hr 10mins on 160c fan bake. I really didn't think it was going to turn out as my skewer kept coming out runny. I wonder if putting it up to 180c on just bake would cook it faster? But anyway, it is extremely moist and delicious, so whatever works! Thanks so much Claire!

    Hi, your cakes looks very nice and moist. Just to clarify a couple of things. Red Velvet is a very old European cake made originally with beetroots. American buttercream is made with icing sugar (confectioners sugar), and fat (e.g. Crisco) and very rarely has real butter in it, but fake butter flavouring instead. The 'icing' in this recipe which is made on the stove with hot milk and flour is usually called German Pastry Cream. The American 'version' of the red velvet cake, has a cream cheese icing with coconut flakes on it and was developed at the Waldorf Hotel in New York (that's apparently still being debated).

      It's just like a mudcake without the chocolate. You'd never guess from the flavour though. Red velvet seems to have been a popular wedding cake choice!

    Ooh yum I love red velvet cake. The best part is cutting into it to see that shock of bright red against the creamy white frosting! I thought American buttercream was just icing sugar + butter as well! I have heard of this frosting before though and it looks pretty yummy. Need to give it a try again! (I'm usually pretty lazy and do the easiest option which is just the icing sugar and butter heheh.)
