Ingredients
To bake this wonderfully wholesome cake, we’ll be using a selection of simple, nourishing ingredients. The true hero is the oatmeal, which we’ll magically turn into a light, fine flour. Here is everything you will need to get started.
For the Carrot Cake:
- 250g rolled oats (ensure they are certified gluten-free if necessary)
- 2 teaspoons baking powder
- 1 teaspoon bicarbonate of soda
- 1 ½ teaspoons ground cinnamon
- ½ teaspoon ground nutmeg
- ½ teaspoon ground ginger
- ½ teaspoon salt
- 3 large free-range eggs
- 180ml pure maple syrup
- 120ml melted coconut oil (or other neutral oil)
- 2 teaspoons vanilla extract
- 300g carrots, peeled and finely grated (about 3 medium carrots)
- 100g walnuts or pecans, roughly chopped (optional)
- 75g sultanas or raisins (optional)
For the Cream Cheese Icing:
- 250g full-fat cream cheese, softened to room temperature
- 120g thick Greek yoghurt
- 60ml pure maple syrup
- 1 teaspoon vanilla extract
Instructions
We have created this recipe to be as simple and enjoyable as possible. By following these easy steps, you’ll soon have a perfect oatmeal carrot cake cooling on your worktop. Our top tip? Be gentle when combining the wet and dry ingredients to avoid over-mixing!
- To begin, let’s get the oven and your tin ready. Preheat your oven to 180°C (160°C Fan / Gas Mark 4). Then, grease and line a 20cm (8-inch) round cake tin with baking parchment.
- Now, it’s time to make the oat flour. Tip the rolled oats into a high-powered blender or a food processor. Blitz on high for around 30-60 seconds, until you achieve a fine, floury texture.
- In a large bowl, whisk together your freshly made oat flour, the baking powder, bicarbonate of soda, cinnamon, nutmeg, ginger, and salt. Mixing these dry ingredients first helps to ensure everything is distributed evenly.
- Using a separate, medium-sized bowl, whisk the eggs until they become light and airy. Next, pour in the maple syrup, melted coconut oil, and vanilla extract, and continue to whisk until thoroughly combined.
- Pour the wet mixture into the bowl containing the dry ingredients. Use a spatula to gently fold everything together until it is just incorporated. A few little lumps in the batter are perfectly okay, so don’t be tempted to over-mix.
- It’s time for the best part of any carrot cake! Carefully fold in the finely grated carrots, followed by the chopped walnuts and sultanas if you have chosen to include them. The batter will be lovely and thick.
- Spoon the batter into your prepared tin, using the back of your spatula to level the surface. Place it in the preheated oven and bake for 35-45 minutes. You’ll know the cake is done when it’s a beautiful golden brown, feels firm, and a skewer inserted into the middle comes out clean.
- Let the cake cool in its tin for approximately 15 minutes. Afterwards, gently turn it out onto a wire rack to cool down completely. It is essential that the cake is entirely cool before you add the icing, or it will simply melt away.
- While your cake is cooling, you can prepare the yummy cream cheese icing. In a medium bowl, use an electric mixer (or a whisk and a bit of effort) to beat the softened cream cheese until it’s smooth. Add the Greek yoghurt, maple syrup, and vanilla extract, and beat again until the mixture is smooth and free of lumps.
- Once the cake has cooled completely, spread the icing evenly and generously over the top. You can make pretty swirls with a spatula or the back of a spoon. For a final flourish, you could sprinkle over a few more chopped walnuts. Your beautiful cake is now ready to slice and enjoy!
Tips for Success
We’re keen for your oatmeal carrot cake to be an absolute triumph. Here are a few extra pointers we’ve picked up:
- Grate Your Own Carrots: For the best texture, grate your own carrots. While shop-bought pre-grated carrots are handy, they can be a bit dry. Freshly grating your own will add essential moisture, resulting in a much more tender cake.
- Room Temperature Ingredients: To get that perfectly smooth, lump-free consistency for the icing, your cream cheese should be properly softened. It helps it blend seamlessly with the other ingredients. The same principle applies to the eggs for the cake.
- Don’t Over-Bake: Be sure to check on it near the end of the cooking time. An over-baked cake can become dry, and our goal here is a deliciously moist result. The skewer test is the most reliable way to check for doneness.
