Can I use regular all-purpose flour instead of white whole wheat flour?

You can, though you will lose some of the fibre benefit. White whole wheat flour has a mild flavour that is very similar to all-purpose flour, so it is worth seeking out if you can. Plain wholemeal flour also works but gives a slightly more rustic texture.

How do I know when the churro cake is fully baked?

Insert a toothpick or thin skewer into the centre of the cake. It should come out clean or with just one or two moist crumbs clinging to it. If batter comes out wet, give the cake another 3 to 5 minutes and check again.

Can I double the recipe for a bigger batch?

Absolutely. Simply double all the ingredients and bake in a 9x13 inch tin. The baking time will increase to roughly 35 to 40 minutes, so keep an eye on it and use the toothpick test to check for doneness.

Is this churro cake suitable for kids?

Yes, it is a great option for kids. The natural sweetness from banana and the lower sugar content make it a much more nourishing treat than shop-bought baked goods, and most children love the warm cinnamon flavour.

Easy Churro Cake with Cinnamon Sugar Topping (Healthier Version)

If you have ever stood at a fairground with a warm churro in hand and thought, I wish I could eat this every day without the guilt, this recipe is your answer. This easy churro cake with cinnamon sugar topping captures everything you love about the classic street food treat: the crisp cinnamon coating, the soft and fragrant interior, and that deeply satisfying warmth that only cinnamon can deliver. Unlike traditional churro cakes that lean heavily on refined white flour, buckets of butter, and cups of white sugar, this version is built with health-conscious bakers in mind. It is genuinely lighter, genuinely nourishing, and genuinely delicious. One slice and you will wonder why you ever needed the original.

The ingredient list is where the magic starts. White whole wheat flour forms the base, giving the cake a tender crumb while adding more fibre than plain all-purpose flour. A ripe mashed banana and unsweetened applesauce step in to replace most of the fat, keeping every slice moist without needing a heavy hand of oil or butter. Coconut sugar replaces refined white sugar throughout, bringing a gentle caramel depth that actually complements the cinnamon beautifully. The cinnamon sugar topping itself uses just one tablespoon of coconut sugar mixed with a generous amount of ground cinnamon, giving you that iconic churro crust on top with a fraction of the usual sweetness. A splash of vanilla extract and a little Greek yogurt round out the batter, adding protein and a subtle tang that balances the spice perfectly.

The texture lands somewhere between a snack cake and a coffee cake, soft and lightly springy in the centre with a slightly crisp, fragrant top from the cinnamon sugar crust. The aroma as it bakes is honestly one of the best things about making this recipe. Your kitchen will smell like a cinnamon-dusted dream. Serve slices slightly warm for maximum flavour, alongside a cup of black coffee, a chai latte, or a glass of cold almond milk. It is equally at home on a weekend breakfast table, a casual afternoon snack spread, or a healthier dessert plate after dinner. A small drizzle of honey over the top just before serving adds a lovely finishing touch if you want something a little extra special.

From a nutritional standpoint, this recipe delivers real advantages over traditional churro cake recipes. Each serving comes in under 210 calories, with a meaningful hit of fibre from the whole wheat flour and banana, and a protein contribution from the Greek yogurt and egg. The total sugar per slice is kept genuinely low by using coconut sugar in small amounts, and the fat content is reduced significantly by skipping butter entirely in the batter. Cinnamon itself is worth mentioning here too: it has been studied for its potential role in supporting healthy blood sugar levels, making it more than just a flavour agent. This cake is not trying to pretend it is a salad. It is a real dessert that tastes indulgent, feels satisfying, and just happens to be made with ingredients your body will appreciate.

Ingredients

Serves:9

1.5 cups white whole wheat flour (spooned and levelled)
1.5 tsp baking powder
0.5 tsp bicarbonate of soda
0.3 tsp fine sea salt
2 tsp ground cinnamon (for the batter)
1 medium ripe banana (mashed until smooth, about 80g)
0.5 cup unsweetened applesauce
0.3 cup coconut sugar (for the batter)
2 tbsp light olive oil or melted coconut oil
1 large egg (at room temperature)
0.5 cup plain low-fat Greek yogurt (at room temperature)
1 tsp pure vanilla extract
0.3 cup unsweetened oat milk (or any milk of choice)
1 tbsp coconut sugar (for the cinnamon sugar topping)
1.5 tsp ground cinnamon (for the cinnamon sugar topping)

Instructions

1
Preheat your oven to 175 degrees Celsius (350 degrees Fahrenheit). Lightly grease an 8x8 inch square baking tin with a little coconut oil or cooking spray, then line the base with baking parchment.
Lining the base makes removing the cake much easier once it has cooled.
2
In a small bowl, mix together the 1 tablespoon of coconut sugar and 1.5 teaspoons of ground cinnamon for the topping. Set this aside.
3
In a large mixing bowl, whisk together the white whole wheat flour, baking powder, bicarbonate of soda, salt, and 2 teaspoons of ground cinnamon until evenly combined.
Whisking the dry ingredients together first ensures the leavening agents are distributed evenly throughout the batter.
4
In a separate medium bowl, mash the banana until completely smooth with no large lumps. Add the applesauce, coconut sugar, olive oil, egg, Greek yogurt, vanilla extract, and oat milk. Whisk everything together until well combined and smooth.
Make sure your egg and yogurt are at room temperature so they incorporate smoothly and help the batter come together without lumps.
5
Pour the wet ingredients into the bowl with the dry ingredients. Using a spatula or wooden spoon, fold gently until just combined. Stop as soon as you no longer see streaks of flour. Do not overmix.
Overmixing develops gluten and can make the cake dense rather than soft. A few small lumps in the batter are perfectly fine.
6
Pour the batter into the prepared tin and spread it evenly with a spatula. Sprinkle the reserved cinnamon sugar topping evenly across the entire surface of the batter.
For a more pronounced churro crust, gently press the cinnamon sugar into the surface with the back of a spoon before baking.
7
Bake in the centre of the preheated oven for 28 to 32 minutes, or until a toothpick inserted into the middle of the cake comes out clean or with just a few moist crumbs.
Start checking at the 28-minute mark. Every oven runs slightly differently, so trust the toothpick test over the timer.
8
Remove the cake from the oven and allow it to cool in the tin for 10 minutes. Then lift it out using the parchment and transfer to a wire rack. Let it cool for at least another 10 minutes before slicing.
Cutting into the cake while it is too hot can cause it to crumble. A little patience goes a long way here.

Pro Tips

✓
Use a very ripe banana with lots of brown spots for the best natural sweetness and the smoothest texture in the finished cake.
✓
Room temperature ingredients blend together more easily and produce a more even crumb, so take the egg and yogurt out of the fridge 30 minutes before you begin.
✓
Do not substitute the Greek yogurt with a runny regular yogurt, as the thicker consistency is important for the batter structure.
✓
If you want an extra cinnamon hit, add a quarter teaspoon of cinnamon directly on top of the cinnamon sugar topping right before the cake goes into the oven.
✓
This cake tastes even better the next day once the cinnamon flavour has had time to deepen and meld through the crumb.

Frequently Asked Questions

Variations

•
Chocolate Swirl Churro Cake
Before adding the cinnamon sugar topping, dot the batter with a few teaspoons of unsweetened cocoa powder mixed with a little coconut sugar, then swirl gently with a skewer for a chocolatey twist.
•
Apple Churro Cake
Fold half a cup of finely diced peeled apple into the batter along with a pinch of nutmeg. The apple pieces add natural sweetness, extra fibre, and a lovely soft texture throughout the cake.
•
Churro Muffins
Spoon the batter into a lined 12-cup muffin tin, filling each cup about two-thirds full. Sprinkle the cinnamon sugar topping over each muffin and bake at 175 degrees Celsius for 18 to 22 minutes.

Substitutions

•
Greek yogurt → Dairy-free coconut yogurt (Use a thick, unsweetened coconut yogurt to keep the batter consistency the same. This also makes the recipe dairy free.)
•
Egg → Flax egg (Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water, stir, and leave for 5 minutes to gel. This works well as a vegan binder in this recipe.)
•
Coconut sugar → Maple sugar or light brown sugar (Both work at a 1-to-1 ratio. Coconut sugar is preferred for its lower glycaemic index, but maple or brown sugar produce a similar caramel-like depth of flavour.)
•
Oat milk → Any plant-based or dairy milk (Almond milk, soy milk, or regular semi-skimmed dairy milk all work here. Just make sure it is unsweetened to avoid adding extra sugar.)
•
White whole wheat flour → Spelt flour (Spelt flour has a naturally mild, slightly nutty flavour and works wonderfully in this cake with no other adjustments needed.)

🧊 Storage

Store cooled cake slices in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. The cinnamon sugar topping softens slightly in the fridge, but a quick 15 seconds in the microwave brings back some of the warmth and texture.

📅 Make Ahead

This cake bakes beautifully the day before serving. Make it, allow it to cool completely, then store it covered at room temperature overnight. The cinnamon flavour actually deepens overnight, making day-two slices arguably even better than day-one.
