A one-bowl banana bread recipe: every AI model's reply, tested

Summarize this YouTube video from its transcript. Start with one sentence on what it's about, then the key points in order.

---
Hey everyone, welcome back to the kitchen. Today it's the easiest banana bread you'll ever make, and it all happens in one bowl. First, preheat your oven to 175 degrees Celsius, that's 350 Fahrenheit, and line a loaf tin with baking paper. Take three really ripe bananas, the spottier the better, and mash them with a fork. Stir in 75 grams of melted butter, then 150 grams of brown sugar, one egg and a teaspoon of vanilla. Now the dry stuff: 190 grams of plain flour, one teaspoon of baking soda and a pinch of salt. Fold it in gently, just until you can't see any flour. Overmixing is what makes banana bread tough, so stop early. Pour it into the tin and bake for 55 to 60 minutes, until a skewer comes out clean. If the top browns too fast, cover it loosely with foil after about 40 minutes. Let it cool in the tin for 10 minutes before you turn it out. That's it. Let me know in the comments what you add to yours; I like a handful of walnuts.
