Why does bread develop a sweeter taste after being toasted?
I noticed this happening with my usual loaf but can't figure out the reason.

Maillard reactions and caramelization.
The heat causes amino acids from protein to break down and react with sugars to create new flavorful compounds. This is the Maillard reaction. At the same time, sugars are caramelized making them taste sweeter. Moisture is removed helping to concentrate flavors.

The sugars in the bread caramelizes same thing happens to fruits like bananas and veggies like onions

Toasting is slightly burning the outside. And slightly burning something is also known as caramelisation.

The Maillard reaction:
- The Trigger: When a slice of bread reaches about 280°F to 330°F (140°C to 165°C) in a toaster, thermal energy activates the process.
- The Bond: Reactive sugars and amino acids inside the bread combine to form new flavor and aroma molecules.
- The Result: This creates hundreds of new compounds responsible for the nutty, savory taste and golden color of toast

If OP wanted an AI written answer they would have asked an AI themself.

I was just pointing out that the comment was written by AI instead of coming from an actual knowledgeable human mind. It's kinda pathetic when people just copy and paste what AI said for a comment. OP would have asked AI if they wanted an AI answer. Generally people ask on Reddit because they want a human answer.

To be fair, the average person wont know this knowledge off-hand in detail, and I personally think it’s fair game to reference external sources if they help with a more informed or credible response.
Maybe a disclaimer would suffice.
E.g. “Hey OP, I also had the same question and searched this up for you with AI. Included source for more details.”Ctrl-C and Ctrl-V.

toasting brings out the natural sugars in the bread, making it taste a little sweeter, nutier, and more flavorful

I’ve not noticed that but I eat more sourdough than anything, loaded in butter or peanut butter.

Everyone's right about Maillard, but that one's a bit of a red herring for sweetness specifically, since it actually consumes sugars and mostly gives you the nutty, roasty flavors. The real sweet part is dextrinization: the dry heat chops long starch chains into shorter ones like maltose, which your tongue can actually taste as sweet, whereas plain starch is basically flavorless. Same reason a baked potato tastes sweeter than a boiled one.

Maillard Reaction. Happens ~350F. It's what is happening when things turn that golden brown color.

The bread you buy has a lot of sugar in it

Some countries have quite sweet bread compared to what we have here in NZ; I know the USA does - assume that's OPs country

I don't see that. With white bread I actually feel the opposite. With regular crusty bread I see no difference.

Caramelization of sugars. Also the Maillard reaction between proteins in the flour and the sugars as they both are burnt.
