Preheat your oven to 350°F (175°C). In a mixing bowl, combine the Bisquick mix and sugar. In another bowl, blend the mashed bananas, vegetable oil, egg, and vanilla until smooth. Gradually add the wet ingredients to the dry and mix until just combined. Avoid overmixing for a tender loaf!
Pour the batter into a greased 9x5 inch loaf pan, smoothing the top with a spatula. Bake in the preheated oven for about 50 minutes or until a toothpick inserted into the center comes out clean.
Once done, let the bread cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Slice and enjoy your fresh banana bread!
Notes
This banana bread keeps well for a few days, and the flavors improve over time!
