Easy Single-Serving Banana Bread Recipe

0 Grease an 8-ounce mini loaf pan, small ramekin, or muffin tin with cooking spray. Then, preheat your oven to 350 F.
1 Take 1/2 a single overripe banana and mash it up with a fork in a small bowl. Add in the oil, egg yolk, vanilla extract, and sugar, to the mashed banana and mix.
2 Stir in the cinnamon, baking powder, salt, and flour until everything is just mixed.
3 Add in the chocolate chips and walnuts.
4 Pour the batter into your prepared ramekin and pop it into the center of your preheated oven for around 20 minutes, or until a toothpick inserted into the center comes out clean.Once it's done, take it out of the oven and let it cool on a wire rack, or enjoy warm banana bread before it's completely cooled.
