Florencia Baldini Last Updated on February 27, 2026Rich. Chocolatey. Super fudgy. The kind of brownie that feels indulgent from the very first bite — with that soft, almost molten centre and deep cocoa flavour.
And here’s the part nobody ever guesses: they’re made with sweet potato.
This recipe is such a game changer. There’s no earthy taste, no savoury undertone — nothing “vegetable-like” at all. Once baked, sweet potato becomes naturally sweet and beautifully soft, creating the perfect base for a dense, fudgy brownie. If I didn’t tell you, you would never know.
No flour. No ultra-processed ingredients. Just simple, wholesome ingredients working together.
Why I Love This Recipe
I love a bake that feels like a proper treat but is secretly nourishing. These brownies are made with almond butter for richness, cacao for deep chocolate flavour, honey for natural sweetness and sweet potato for that dreamy texture.
They’re mixed in one bowl, made with just a handful of ingredients and require no fancy equipment. Real food. Real flavour. Buonissimo.
Why Sweet Potato Works So Well
Sweet potatoes are naturally sweet, especially once cooked and baked. Their natural sugars caramelise slightly in the oven, giving that soft, fudgy consistency we usually rely on refined flour and sugar to achieve.
Unlike white flour, sweet potato contains fibre, vitamins and antioxidants such as beta-carotene. The fibre helps slow down the release of sugars into the bloodstream, meaning you get steadier energy rather than a sharp spike. When paired with healthy fats from almond butter, the overall glycaemic impact is gentler than traditional brownies made with refined flour.
So instead of using an ultra-processed base, we’re using a whole root vegetable that brings natural sweetness, structure and nourishment — without compromising on texture.
Naturally Gluten Free
There’s no gluten here because there’s no flour at all. The structure comes from the combination of sweet potato and almond butter, creating a brownie that’s soft in the centre yet holds together beautifully once cooled.

Why This Recipe Is Good For You
This one-pan berry baked oats is more than just an easy breakfast — it’s designed to keep you full, energised and satisfied all morning. The oats and berries provide plenty of fibre to support digestion and steady energy levels, while the ground almonds and pecans add healthy fats that help with satiety. Using ripe bananas and just a small amount of honey keeps the sweetness natural and balanced, avoiding big sugar spikes. When served with yoghurt, it becomes a complete meal, adding protein and moisture for a breakfast that’s nourishing, comforting and genuinely sustaining — exactly what busy mornings need.
How To Bake Sweet Potatoes
To bake a sweet potato, preheat your oven to 200°C. Give the sweet potato a good scrub and pat it dry, then prick it a few times with a fork to allow steam to escape.
Place it on a lined baking tray and bake for 40–50 minutes, depending on its size, until the skin is crisp and the inside is soft all the way through. You’ll know it’s ready when a knife slides in easily. Let it rest for a few minutes before slicing open.
Baking Dish Notes
I use a small 16 x 12 cm (6.3 × 4.7 inch) baking dish and always line it with parchment paper. It makes lifting the brownie out so much easier once it’s baked, especially with a fudgy texture like this.
As soon as it comes out of the oven, carefully transfer it to a cooling rack. Letting it cool completely will make slicing much neater and cleaner — but if you love a warm, super fudgy centre, feel free to dig in straight away.
This recipe makes a small batch, which I actually love for portion control. I cut it into 6 squares, and they’re the perfect size for a satisfying treat without overdoing it.
All The Ingredients Are From Ocado *
I switched my food shopping to Ocado a few months ago and genuinely haven’t looked back. I love that I can always find everything I need for my recipes and testing — even those slightly harder-to-find ingredients that my local supermarket doesn’t always stock. There’s almost always a delivery slot available too, which means I can order at short notice, sometimes even for the same day. On busy weeks, that’s such a lifesaver.
What I really appreciate is the variety — from well-known brands to M&S and the Ocado own range, it makes everything feel seamless and convenient. For this recipe, I used sweet potatoes and honey from the Ocado range, M&S 70% dark chocolate, ‘Naturya Organic Fair Trade Cacao Powder’, and ‘Pip&Nut’ Almond Butter.
I’m partnering with Ocado, and I’m so chuffed to be able to give you a special discount.
If you’ve never shopped with Ocado before, you can use code FLO30 on the Ocado website to get 30% off your first order plus 3 months of unlimited free deliveries. Such an amazing offer—let me know in the comments if you’ll be using it .

Tips & Hacks
Mash while warm: Warm sweet potato blends more smoothly and gives the fudgiest texture.
Don’t overbake: Slightly underbaked is perfect — they’ll firm up as they cool.
Use good chocolate: A 70% dark chocolate keeps them rich without being overly sweet.
Storage
Fridge: Store in an airtight container for up to 4 days. They become even fudgier the next day.
Freezer: Slice and freeze for up to 3 months. Defrost at room temperature or warm slightly before serving.

Ingredients
- 150 g cooked sweet potato
- 100 g almond butter
- 15 g cacao
- 1 egg
- 50 g honey
- 30 g 70% dark chocolate, chopped (or chocolate chips)
Instructions
- Use leftover cooked sweet potato or bake one from scratch (see instructions above). Add the cooked sweet potato to a bowl and mash really well until you have a smooth purée.
- Add the almond butter, cacao powder, honey and egg, then mix until fully combined. You can use a fork for this, but if you prefer an ultra-smooth texture, a hand blender works beautifully.
- Transfer the mixture into a small baking dish lined with parchment paper. Fold in most of the dark chocolate chips, keeping a few aside to sprinkle over the top. Smooth the surface, then scatter the remaining chocolate chips on top.
- Bake in a preheated oven at 180°C for about 30 minutes. If you prefer a gooier centre, remove the brownie from the oven around 5 minutes earlier. Once baked, lift it out using the parchment paper and allow it to cool completely on a wire rack before slicing.
Recipe looks great! If I’m in a pinch, can I microwave my potato instead? Thank you for the reply!
Personally, I would use the oven if you can. I did try microwaving the potato once and wasn’t very happy with the result. It tends to dry out the inside of the potato a bit, which can make the brownies less soft and fudgy.
If you’re short on time though, the microwave is still a good shortcut for cooking potatoes quickly. Just make sure it’s cooked until really soft and still moist inside when you cut into it. Happy cooking 😊
