Did you know that the traditional red velvet cake was only 'red' because of the chemical reaction between cocoa powder and buttermilk?
These days, red velvet cake is a vivid red colour with the addition of food colouring.
This soft, rich and moist cake is my absolute favourite special-occasion cake. It looks impressive but is ridiculously simple. All you need to do is whisk the wet and dry ingredients together!
I top this cake with a smooth cream cheese frosting and decorate the top and sides with crumbled cake offcuts. It always impresses and feeds a fair crowd. Enjoy!
Top Tips & FAQs
- Do I have to use buttermilk? In short, yes. Buttermilk substitutes (such as milk combined with vinegar or lemon juice) don't work as well in this recipe and will produce a drier cake. You should be able to find buttermilk at most major supermarkets (in the US, UK and AUS) or in specialty/organic food shops.
- What type of red food colouring should I use? I use a high quality liquid food colouring. This dissolves easily into the batter and produces a vivid red colour even after baking. If you only have access to gel food colour, make sure it is high-quality and start by only using 1 tablespoon (then add more as needed).
- Baking soda or baking powder? Red velvet cakes use baking SODA as a raising agent. This gives the cake its distinctive tangy flavour. In a pinch, you can substitute 1 tsp of baking soda with 3 tsp of baking powder for this recipe.
- Why does this recipe use both oil AND butter? Oil keeps the cake moist and soft, while butter gives the cake a beautiful rich flavour.
- Why is my batter runny? This batter is fairly thin (and that is okay!). Make sure your spring-form pan is tightly sealed so the batter does not leak out. Do NOT bake this cake sitting on top of a cookie tray or it will not bake evenly.
- Why is my cake dry/dense/sunken?
- You are measuring your dry ingredients incorrectly: to measure dry ingredients such as flour, measure spoonfuls of flour into a measuring cup until it is heaped (do not pack down), then sweep off the excess with a flat-bladed butter knife.
- You overcooked the cakes: make sure to follow the recommended temperature guidelines and cooking times. These cakes do not tend to brown all across the surface so you must test your cakes with a skewer - it should be clean when inserted and removed from the centre of the cake, or just have a few moist clinging crumbs.
- Your baking soda is expired: check the expiry date of your baking soda. Expired baking soda is a VERY common cause of sunken or dense cakes.
For the Red Velvet Cakes
- 2 ¼ cups plain / all-purpose flour
- ¼ cup corn starch / cornflour
- 2 tbsp unsweetened cocoa powder
- 1 tsp baking soda / bicarbonate of soda
- 1 tsp salt
- 1 cup canola oil (or any other flavourless vegetable or cooking oil)
- 125g (½ cup) unsalted butter, melted and cooled slightly
- 1 ½ cups caster / superfine sugar
- 2 eggs
- 1 tsp white vinegar
- 1 cup buttermilk (substitutes do not work well for this recipe)
- 1 tbsp vanilla essence OR 2 tsp vanilla extract
- 2 tbsp red liquid food colouring OR 1 tbsp high-quality gel food colouring
For the Cream Cheese Frosting
- 125 g (½ cup) unsalted butter, at room temperature
- 250 g (1 cup) block of cream cheese, at room temperature
- 4 cups icing / powdered sugar
- 2 tbsp lemon juice
- 2 tsp vanilla essence OR 1 tsp vanilla extract
For the Red Velvet Cakes
- Preheat the oven to 160°C/320°F (fan-forced/convection) or 180°C/355°F (standard). Grease and line TWO pans measuring 20 cm (8 inch) with baking paper.
- In a large mixing bowl, sift together the flour, corn starch, cocoa powder, baking soda and salt. Whisk until well combined.
- In a separate large bowl, whisk together the oil and the cooled butter until well combined. Add sugar, eggs, vinegar, buttermilk, vanilla and food colouring. Whisk until well combined.
- Pour the wet ingredients into the dry ingredients and whisk until combined (a few lumps are okay - don't overbeat).
- Evenly distribute the batter between the two prepared tins. Bake for 35-40 minutes or until lightly browned around the edges and a skewer inserted in the centre of the cakes comes out clean.
- Allow to cool for 10 minutes in the tins before transferring to a wire rack to cool completely.
For the Cream Cheese Frosting
- In the large bowl of an electric mixer (or using a hand mixer), beat together the butter and cream cheese until thick, pale and creamy (about 3-4 mins).
- Add the icing sugar, lemon juice, and vanilla, and beat until very pale and thick (about 5 minutes). Add more icing sugar or lemon juice to adjust consistency as needed.
- If the cakes are very domed, level the top of each cake with a serrated knife.
- Place one cake on a large, flat plate. Top with one quarter of the cream cheese frosting and spread the frosting evenly over the cake.
- Flip the second cake upside down onto the first. Top with half of the remaining frosting, spreading the frosting from the centre towards the edges of the cake.
- Use the remaining frosting to cover the sides of the cake. Use a flat (palette) knife to smooth out the top and sides.
- Crumble up the offcuts of the cake and sprinkle along the sides and top of the cake, if desired.
- Refrigerate for 1-2 hours or until frosting is firm. Keep the cake refrigerated until ready to serve.
- Keep the frosted cake covered in the refrigerator for up to 4 days.
- To freeze the unfrosted cakes: wrap cooked cakes individually in clingfilm and place in zip-loc or freezer bags. Keep frozen for up to 6 months. Defrost for 6 hours or overnight at room temperature and frost as normal.
Substitutions & Tips
- Baking soda vs baking powder: baking soda is more potent than baking powder and has a somewhat tangy taste. Baking soda will help give red velvet cake its essential slightly tangy flavour. In a pinch, you can substitute 1 tsp of baking soda with 3 tsp baking powder.
- Canola oil: use any flavourless vegetable or cooking oil. Do not use coconut oil, olive oil, avocado oil, or any other strongly flavoured oils.
- Buttermilk: most recipes allow you to substitute buttermilk for a combo of milk and vinegar. However I do NOT recommend substituting buttermilk for milk in this recipe. It is an essential ingredient for a rich and tangy red velvet cake.
- White vinegar: substitute with an equal amount of apple cider vinegar, brown vinegar, malt vinegar, etc. Do NOT use balsamic vinegar.
- Baking your cakes evenly: my oven fits two cake tins on one rack. I recommend baking both tins in one rack and rotating at around the 25 minute mark. You can also bake one cake after the other to ensure very even cooking.
