Is Baking a Cake a Chemical Change

Is baking a cake a chemical change you may wonder. Some believe that baking is an art itself as well as science, and based on our experience, it’s true.

Furthermore, baking is like being a chemist – you need to understand how things work in a very chemical way if you like.

Every beginner baker thinks that baking is just mixing some stuff up, baking them, and boom – you have the perfect baked good. The truth is, if you want to be a good baker or a pastry chef, you really gotta understand every single chemical reaction that occurs during the baking process.

And today, we are here to do exactly that – help you understand an important part of the baking process!

Is Baking a Cake a Chemical Or Physical Change

Both! Think about it – when you add the batter to the cake pan, it looks one way, but once you take it out of the oven – it looks completely different, doesn’t it?

Of course, it’s due to the chemical reactions mainly, but you have to remember that you start with physical ingredients and then you let the magic happen.

Why is baking a cake a chemical change, though? – Well, it’s often the carbon dioxide from the baking powder that gets released when it gets hit by the heat.

To put this simply  Рbubbles appear that get trapped, which leads to the cake rising. If you cut a piece of cake, you can see all the irregular structures, this is basically due to the chemical reaction.

Furthermore, it’s not just the baking powder that causes the rice or a chemical reaction. Eggs do that too, heat does that, and the mix of ingredients together achieves a chemical reaction too. It’s all a big magic!

Is Baking a Cake An Example Of Chemical Change

Absolutely. And it’s not just baking you know… it’s with every type of cooking really. When you boil an egg, it comes out hard.

When you expose certain ingredients to certain situations like heat, and moisture, for example, they react.

What Type Of Chemical Change Is Baking a Cake?

Typically, it would be carbon dioxide (chemical formula CO 2) – but as mentioned above, eggs are a chemical reaction that occurs during the baking process as well.
You see, there are a lot of changes that happen in the oven, a lot of reactions occur the moment the heat hits the batter.

Baking a Cake is a Chemical Change Because…

…Of the reaction in the baking powder that releases gas and traps bubbles, from the egg’s protein, and from the sugar melting. It’s also worth mentioning that the fat that in the cake has a very important role to play. All the chemical reactions that happen can often dry up the cake, but that’s where the fat comes in to keep it soft and spongy.

Furthermore, the fat also acts as a barrier, that holds everything together. You don’t want those bubbles escaping…


1. Chemical Reactions In Baking Cookies
What about cookies though? Pretty much the same as cakes, if you think about it, often the same ingredients that go into a cake batter, go into the creations of cookies, just in different proportions.

You have got eggs, sugar, baking powder/baking soda, fat, flour, etc.

2. Is Baking Always a Chemical Change?
Absolutely, baking is 100% a chemical change, without it, we wouldn’t get the results we want, hence the reason we manipulate different reactions out of the ingredients via quantity and heat.

3. Is Mixing a Cake a Chemical Change?
When you mix the cake batter and add the ingredients together, a reaction happens right there in that bowl. How?

Well, to begin with, you are crushing ingredients together, combining them with each other.

Furthermore, When you expose certain ingredients to moisture, for example, they start reacting. A good example is a baking powder and baking soda, they start releasing gasses when they are exposed to moisture.

4. Is Baking Bread a Chemical Change?
Very much so! Remember, you are working with yeast, yeast itself is almost just like baking powder, when it’s exposed to heat or moisture, it reacts.



Fascinating isn’t it? We don’t think of cake in that way, we just like to eat it! But what goes on behind the scenes is something very fascinating.

Cake chemistry is a thing guys, and today you learn your first lesson of exactly what happens when you bake a cake and its chemical reactions, as well as how is baking a cake a chemical reaction.
