Cacao and cocoa are the same bean — Theobroma cacao — handled differently: cacao powder is cold-pressed from unroasted beans, while cocoa powder is roasted first, which is why it tastes mellower and less bitter. But the difference that actually matters in baking is not raw versus roasted, it is natural versus Dutch-processed. Natural cocoa and raw cacao are acidic (pH 5.0 to 5.8) and react with baking soda (bicarbonate of soda) to raise a cake, whereas Dutch-processed cocoa has been alkalised (pH 6.8 to 8.0) and will not react at all — swap it into a recipe leavened only with baking soda and you get a flat, dense cake with a soapy taste.
There is a whole aisle of brown powder out there and the tins are no help at all. Here is the short of it: what the label calls it matters far less than whether it has been alkalised. Get that one thing right and your cake rises. Get it wrong and no amount of good chocolate will save you.
| Product | Fat | pH | Reacts with baking soda? | Swap for natural cocoa |
|---|---|---|---|---|
| Raw cacao powder | 10-14% | 5.3-5.8 (acidic) | Yes | 1:1 by weight. More bitter, a touch fruitier. |
| Natural cocoa powder | 10-12% | 5.0-5.6 (acidic) | Yes | This is the baseline. |
| High-fat natural cocoa (breakfast cocoa) | 22-24% | 5.0-5.6 (acidic) | Yes | 1:1. Richer, softer crumb. The extra fat is only about 6 g per 50 g of cocoa, so most recipes cope unadjusted. |
| Dutch-processed cocoa (alkalised, Dutched, cacao rouge) | 10-12% (up to 24%) | 6.8-8.0 (neutral to alkaline) | No | 1:1 by weight, BUT replace each 1 tsp baking soda with 3 tsp baking powder. |
| Black cocoa | 10-12% | 7.8-8.2 (alkaline) | No | Use for no more than a quarter of the total cocoa. Above that it bakes dry and ashy. |
| Cacao nibs | 45-55% | 5.0-5.5 (acidic) | Not applicable | No swap possible. They are crunchy pieces of bean, not a powder. |
| Unsweetened baking chocolate | 50-55% | 5.0-5.8 (acidic) | Yes | Reverse swap: 20 g cocoa plus 15 g butter or oil = 30 g (1 oz) chocolate. |
Cacao Powder vs Cocoa Powder: What Actually Changes
Both start as beans from the cacao pod, fermented and dried in the sun. Cacao powder is then cold-pressed at low temperature — usually under 48C (118F) — and the cocoa butter squeezed out, leaving a powder that has never been properly roasted. Cocoa powder gets a real roast first, somewhere around 120C to 150C (250F to 300F), and that roast is what builds the deep, familiar chocolate smell and knocks the harsh edges off.
In the bowl the difference is smaller than the price tag suggests. Raw cacao powder is more bitter, more astringent and slightly fruitier. Cocoa powder is rounder and more chocolatey. Both sit at roughly 10 to 14 per cent fat and both are acidic, so cacao powder swaps into a natural cocoa recipe at 1:1 by weight with nothing else changed — just expect a sharper cake. One honest note while we are here: almost no cacao powder is genuinely raw. Fermentation alone pushes the beans to 45C to 50C in the heap before anyone presses anything.
Cacao Nibs vs Cocoa Powder: The Differences That Matter
Cacao nibs are not a powder at all, and this trips people up constantly. Nibs are the whole bean cracked into crunchy little pieces with all the cocoa butter still inside them, which is why they run 45 to 55 per cent fat against 10 to 14 per cent for a powder. That fat is the entire difference. Cocoa powder is simply what is left over once the butter has been pressed out.
So they do not swap, and you cannot make one into the other at home. Grind nibs in a food processor and you get a thick paste, not a powder — there is far too much fat in there to stay dry. Nibs are for crunch and bitterness: scattered over a frosted cake, stirred through cookie dough, on porridge, in granola. They taste like very dark chocolate with no sugar whatsoever and they never soften in the oven, so they stay crisp. If a recipe asks for 25 g of cocoa powder, nibs will not do it. If a recipe asks for chocolate chips and you want less sweetness, nibs are a fair swap by weight.
Natural vs Dutch-Processed Cocoa: The Bit That Ruins Bakes
This is the one worth knowing. Natural cocoa powder is acidic, pH 5.0 to 5.6. Dutch-processed cocoa — also sold as alkalised, Dutched, or cacao rouge — has been washed with a potassium carbonate solution that neutralises that acid and takes it to pH 6.8 to 8.0. It comes out darker, redder, mellower and much less bitter. It also comes out chemically inert.
Baking soda (bicarbonate of soda) is a base. It needs an acid to fizz against, and in plenty of chocolate recipes the natural cocoa IS that acid — the only one in the bowl. Put Dutch cocoa in instead and the bicarbonate has nothing to react with: the cake bakes flat and dense, and the unreacted bicarbonate tastes soapy and faintly metallic. So the rule of thumb is simple. Natural cocoa goes with baking soda. Dutch-processed goes with baking powder, which carries its own acid built in.
Before you panic about every recipe you own, read the rest of the ingredients. If there is buttermilk, soured cream, vinegar, treacle, brown sugar or hot coffee in there, the bicarbonate has plenty of acid without the cocoa and Dutch is usually safe. Our old-fashioned wacky cake is a good example — it has vinegar in it, so it will rise either way. It is the plain devil's food made with milk, cocoa and bicarbonate and nothing else acidic that Dutch cocoa flattens.
How to Swap Dutch-Processed for Natural Cocoa (and Back)
If the recipe says natural cocoa and all you have is Dutch, keep the cocoa 1:1 by weight and fix the leavening instead: replace each 1 tsp of bicarbonate of soda with 3 tsp of baking powder. It is a blunt fix — that much baking powder brings extra sodium and a slight aftertaste — but the cake will rise, which beats the alternative. And again, if the recipe already has buttermilk, soured cream, vinegar, treacle or hot coffee in it, leave the leavening entirely alone.
Going the other way is far easier. Natural cocoa into a Dutch-cocoa recipe leavened with baking powder: use it 1:1 and expect a slightly paler, redder, tangier cake. If you want to mellow it towards Dutch, add a pinch of bicarbonate of soda — 1/8 tsp per 20 g (3 tbsp) of natural cocoa, and not a grain more. Overdo it and you are back to soap.
Is Raw Cacao Healthier Than Cocoa?
A little, on paper. Raw cacao does keep more flavanols — the antioxidant compounds that roasting degrades — along with more magnesium and iron. The trouble is that you are about to put 25 g of it into a cake and bake it at 180C (fan 160C / gas 4) for half an hour, which undoes the point rather thoroughly. Heat is heat, whether it happens at the factory or in your oven.
So if the health claim is why you are buying cacao powder, eat it in something that never gets hot: a smoothie, bliss balls, stirred into porridge off the heat, or nibs on yoghurt. For baking, buy on flavour and pH and ignore the word on the front of the tin. A good natural cocoa for anything leavened with bicarbonate of soda. A good Dutch for brownies, custards, ice cream and hot chocolate, where there is no leavening to worry about and its dark, mellow flavour has room to show off.
Questions we get asked
Is cacao the same as cocoa?
Same bean, different processing. Both come from Theobroma cacao. Cacao powder is cold-pressed from unroasted beans; cocoa powder is roasted first, which makes it mellower and less bitter. In baking they behave almost identically — both are acidic and both react with baking soda — so cacao powder swaps for natural cocoa 1:1 by weight.
Can I use cacao powder instead of cocoa powder?
Yes, 1:1 by weight, as long as the recipe calls for natural cocoa rather than Dutch-processed. Your bake will taste sharper and more bitter, with a slightly fruity edge. Do not use cacao powder as a straight swap in a recipe built around Dutch cocoa and baking powder without expecting a tangier, paler result — though it will still work.
What is the difference between cacao nibs and cocoa powder?
Fat, mostly. Nibs are cracked whole beans with the cocoa butter still in them, at 45 to 55 per cent fat. Cocoa powder is what is left after that butter has been pressed out, at 10 to 14 per cent. They are not interchangeable in either direction — nibs stay crunchy and will not dissolve, and grinding them gives you paste, not powder. Use nibs for crunch and bitterness, roughly as you would chocolate chips.
How do I know if my cocoa powder is Dutch-processed?
Read the ingredients. If it says processed with alkali, alkalised, or potassium carbonate, it is Dutch. If it just says cocoa, it is natural. Hershey's in the brown box and Ghirardelli are natural; Droste, Valrhona and Cacao Barry are Dutch, and most European supermarket cocoa is Dutched by default. Colour is a rough clue — natural is a lighter reddish-brown, Dutch is darker. The old baking soda fizz test does work in theory, but natural cocoa is only mildly acidic and the fizz is so faint it is not worth trusting. Read the label.
Can I substitute Dutch-processed cocoa for natural cocoa?
Yes, but you must fix the leavening or the bake will fail. Keep the cocoa 1:1 by weight, then replace each 1 tsp of bicarbonate of soda with 3 tsp of baking powder. The exception: if the recipe already contains buttermilk, soured cream, vinegar, treacle or hot coffee, there is enough acid without the cocoa, so change nothing at all.
What happens if you use Dutch-processed cocoa with baking soda?
Not much, and that is the problem. Dutch cocoa has been alkalised to pH 6.8 to 8.0, so there is no acid for the bicarbonate of soda to react with. If the cocoa was the only acid in the recipe, the cake bakes flat and dense, and the leftover unreacted bicarbonate tastes soapy and slightly metallic. It is the single most common way a chocolate cake goes wrong.
