📖 Instructions

1. First things first, preheat your oven. Get it to a solid 350°F (175°C). This ensures your bread starts baking immediately and evenly. Don't skip this; a cold oven is a sad oven.
2. Next, prepare your loaf pan. Take a standard 9x5-inch loaf pan and lightly grease it. Then, line it with parchment paper, making sure some paper hangs over the long sides. This creates 'handles' that will make lifting the baked bread out super easy. Believe me, it's a game-changer.
3. In a medium bowl, mash those gloriously ripe bananas. You can use a fork for a chunkier bread or a potato masher for a smoother consistency. I like a few small lumps myself; it adds character. Just mash 'em good, okay?
4. Now, let's get our dry ingredients ready. In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking soda, and salt. Make sure it's all well combined. We don't want any surprises from pockets of baking soda!
5. Time for the wet ingredients (besides the bananas). In a separate small bowl, whisk together the mashed bananas, the large egg, melted unsalted butter, and vanilla extract. Give it a good mix until everything is just combined. No need to go crazy here.
6. Pour the wet banana mixture into the dry ingredients. With a rubber spatula, gently fold them together until just combined. The key word here is 'just'. Overmixing will lead to a tough bread, and nobody wants that. A few streaks of flour are perfectly fine.
7. Melt your dark chocolate. You can do this gently in the microwave in 30-second bursts, stirring in between, or over a double boiler. Once smooth and glossy, let it cool for a minute or two. We don't want it too hot, or it'll just sink to the bottom.
8. Add about two-thirds of the batter to your prepared loaf pan. Dollop about half of the melted dark chocolate over this layer. Take a knife or a skewer and gently swirl the chocolate into the batter. Don't overdo it, or you'll lose the beautiful swirl effect. Less is more here.
9. Carefully spoon the remaining batter over the swirled layer. Then, dollop the rest of the melted dark chocolate on top. Repeat the swirling process with your knife or skewer, creating those lovely ribbons of chocolate.
10. Sprinkle a few extra chocolate chips on top if you're feeling fancy (and why wouldn't you be?). This also helps create a lovely cracked crust during baking.
11. Bake the banana bread for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean or with moist crumbs, but no wet batter. Around the 40-minute mark, check on it. If the top is browning too quickly, you can loosely tent it with aluminum foil.
12. Once baked, remove the loaf pan from the oven and let it cool on a wire rack for about 10-15 minutes. This is crucial for it to set up properly. Trust the process!
13. After cooling a bit, use those parchment paper handles to carefully lift the banana bread out of the pan and transfer it to the wire rack to cool completely. Slicing it while still hot is tempting, I know, but it will be much cleaner and less crumbly if you wait until it's cooled. Seriously, I've made that mistake more times than I care to admit.
14. Slice it up, grab a cup of coffee, and savor every single, glorious bite. You've earned this!
